treatment. Across orthopedic, cardiac, gastrointestinal, oncologic, and general surgery populations, preoperative malnutrition and unrecognized nutrition risk are consistently associated with more postoperative complications, longer length of stay, higher resource utilization, and, in some populations, higher mortality. At the same time, evidence from systematic reviews and selected trials shows that targeted nutrition interventions, particularly early screening, oral nutrition supplements, immune-modulating formulas in selected gastrointestinal cancer patients, avoidance of prolonged fasting, carbohydrate loading where appropriate, and early postoperative feeding within Enhanced Recovery After Surgery (ERAS) pathways, can improve clinically meaningful outcomes.\r\n      <\/p>\r\n\r\n      <p>\r\n        The central position of this paper is that nutrition should be operationalized as a routine perioperative quality and safety strategy. Surgical patients should be screened early for malnutrition risk, triaged for intervention, and managed with diagnosis-specific and procedure-specific nutrition plans integrated into ERAS workflows.\r\n      <\/p>\r\n\r\n      <p>\r\n        Although the strength of evidence varies by surgical specialty and intervention, the aggregate literature supports three conclusions: first, malnutrition is common and prognostically important; second, single laboratory markers such as albumin should not be used in isolation to define nutritional status; and third, structured perioperative nutrition care can reduce complications and improve recovery, especially in higher-risk patients. (1-7)\r\n      <\/p>\r\n    <\/section>\r\n\r\n\r\n    <section id=\"malnutrition-risk\">\r\n      <h2>Malnutrition, Nutrition Risk, and Adverse Surgical Outcomes<\/h2>\r\n\r\n      <p>\r\n        Malnutrition before surgery reflects both inadequate intake and the metabolic consequences of disease, inflammation, and catabolism. In practical terms, this means that weight loss, poor oral intake, loss of lean body mass, frailty, and disease burden often coexist.\r\n      <\/p>\r\n\r\n      <p>\r\n        In elderly general surgery patients, a systematic review found that preoperative serum albumin and recent weight loss were the only parameters consistently linked with postoperative outcome, underscoring both the clinical importance of nutrition risk and the limitations of the available evidence base. The authors also noted that albumin is not a pure nutrition marker and likely reflects disease severity and inflammatory burden in addition to nutrition status. (3)\r\n      <\/p>\r\n\r\n      <p>\r\n        This point is especially relevant for contemporary practice. More recent orthopedic evidence likewise cautions against relying on single biochemical measures alone. A 2026 meta-analysis of 11 studies including 201,338 geriatric orthopedic patients reported that malnutrition identified by nutrition screening tools was associated with a 65% higher risk of postoperative complications and more than double the risk of postoperative mortality. The signal was strongest in hip surgery populations, supporting the use of validated screening tools rather than isolated biomarkers in older adults. (6)\r\n      <\/p>\r\n\r\n      <p>\r\n        From a nutrition and dietetics perspective, the implication is clear; perioperative nutrition assessment should move beyond albumin-only thinking. Weight history, recent intake, functional decline, body mass index, muscle loss or sarcopenia, and validated tools such as SGA, MUST, NRS-2002, MNA, GNRI, or procedure-specific risk frameworks provide a more clinically useful basis for identifying patients who need intervention. (3,5,6)\r\n      <\/p>\r\n    <\/section>\r\n\r\n\r\n    <section id=\"surgery-outcomes\">\r\n      <h2>Outcomes by Major Type of Surgery<\/h2>\r\n\r\n      <h3>Orthopedic Surgery<\/h3>\r\n\r\n      <p>\r\n        Orthopedic patients, particularly older adults with hip fracture or major joint replacement, have a high prevalence of nutrition risk because of age, inflammation, immobility, and acute catabolic stress.\r\n      <\/p>\r\n\r\n      <p>\r\n        In hip fracture surgery, a meta-analysis of five randomized controlled trials including 654 geriatric patients found that preoperative protein-based oral nutrition supplements significantly reduced postoperative complications (OR 0.48, 95% CI 0.26\u20130.89), but did not significantly reduce in-hospital mortality or length of stay. The authors concluded that benefits were real but limited, which is consistent with the view that nutrition support improves morbidity more reliably than mortality in short, acute orthopedic episodes. (4)\r\n      <\/p>\r\n\r\n      <p>\r\n        For elective arthroplasty, a randomized trial in elderly patients undergoing total knee arthroplasty found that a preoperative oral electrolyte-carbohydrate supplement improved subjective comfort, reduced hyponatremia, improved perioperative glucose-related outcomes, and reduced infusion volume without increasing complications.\r\n      <\/p>\r\n\r\n      <p>\r\n        While this was not a malnourished cohort and did not demonstrate differences in major postoperative events, it supports ERAS-aligned nutrition practices such as minimizing prolonged fasting and using structured preoperative drinks in appropriately selected patients. (7)\r\n      <\/p>\r\n\r\n\r\n      <h3>Cardiac Surgery<\/h3>\r\n\r\n      <p>\r\n        Cardiac surgery presents a distinct nutrition challenge because of advanced age, multimorbidity, chronic heart failure, inflammation, and postoperative critical care needs. A narrative review of adult cardiac surgery concluded that malnutrition is associated with longer ICU stay, longer mechanical ventilation, more cardiovascular and infectious complications, and postoperative delirium after CABG.\r\n      <\/p>\r\n\r\n      <p>\r\n        Reported prevalence of malnutrition or nutrition risk ranged widely, from 1.2% to 46.4%, reflecting inconsistent definitions and tools. (5)\r\n      <\/p>\r\n\r\n      <p>\r\n        The cardiac surgery literature supports routine preoperative screening, aggressive attention to protein-energy adequacy, and early enteral nutrition when oral intake is not feasible. It also highlights the need to identify sarcopenia, frailty, and cachexia rather than focusing only on body weight.\r\n      <\/p>\r\n\r\n      <p>\r\n        The practical takeaway is that nutrition in cardiac surgery should be embedded in prehabilitation and ERAS-style perioperative care bundles, with special attention to avoiding unnecessary fasting and initiating postoperative feeding early when clinically appropriate. (5)\r\n      <\/p>\r\n\r\n\r\n      <h3>Gastric and Other Gastrointestinal Cancer Surgery<\/h3>\r\n\r\n      <p>\r\n        The evidence is especially strong in upper gastrointestinal and oncologic surgery, where baseline malnutrition is common and biologically plausible as a driver of poor wound healing, infection, and reduced tolerance of treatment.\r\n      <\/p>\r\n\r\n      <p>\r\n        In a large study of 1,976 patients undergoing radical gastrectomy, malnourished patients had a significantly higher overall complication rate than well-nourished patients (21.4% vs 15.5%), as well as worse 3-year overall survival (59.1% vs 75.0%) and disease-free survival (54.8% vs 72.5%).\r\n      <\/p>\r\n\r\n      <p>\r\n        Malnutrition was an independent predictor of both overall and disease-free survival. Among malnourished patients with stage II\u2013III disease, correction of preoperative hypoproteinemia was associated with improved 3-year overall survival and disease-free survival, suggesting that nutrition optimization before surgery may affect not only short-term recovery but also longer-term oncologic resilience. (2)\r\n      <\/p>\r\n\r\n      <p>\r\n        A meta-analysis of 16 studies involving 1,387 patients undergoing surgery for gastrointestinal cancer found that preoperative immune-modulating nutrition reduced infectious complications by nearly half (OR 0.52, 95% CI 0.38\u20130.71) and shortened hospital stay by 1.57 days, although it did not significantly reduce noninfectious complications or mortality.\r\n      <\/p>\r\n\r\n      <p>\r\n        These findings are clinically meaningful because infectious complications are among the most common drivers of delayed recovery, extended hospitalization, and increased cost in GI cancer surgery. The evidence supports selective use of oral or enteral immune-modulating formulas, particularly in higher-risk GI oncology populations. (1)\r\n      <\/p>\r\n\r\n\r\n      <h3>General Surgery<\/h3>\r\n\r\n      <p>\r\n        In elderly general surgery, the literature is more heterogeneous, but the direction of effect is consistent: patients entering surgery with significant recent weight loss, low intake, frailty, or low albumin have worse postoperative outcomes.\r\n      <\/p>\r\n\r\n      <p>\r\n        The 2013 systematic review by van Stijn and colleagues found that serum albumin and at least 10% weight loss in the prior six months were the only preoperative parameters clearly linked to postoperative outcome.\r\n      <\/p>\r\n\r\n      <p>\r\n        Importantly, the review emphasized that the field needs more rigorous and consistent definitions of nutrition status, but that clinicians should not wait for perfect evidence before acting on obvious nutrition risk.

Nutrition is not a peripheral component of ERAS; it is one of its core operational elements.\r\n      <\/p>\r\n\r\n      <p>\r\n        Across ERAS pathways, the nutrition-related themes are remarkably consistent: preoperative nutrition screening, avoidance of prolonged fasting, use of carbohydrate beverages up to a few hours before anesthesia in appropriate patients, attention to glycemic management, early postoperative oral or enteral feeding, and escalation to oral nutrition supplements or enteral nutrition when intake is inadequate.\r\n      <\/p>\r\n\r\n      <p>\r\n        The outcomes most consistently associated with ERAS-aligned nutrition practices are improved patient comfort, reduced insulin resistance, earlier return of gastrointestinal function, fewer infectious complications in selected populations, shorter length of stay, and lower overall morbidity when these practices are delivered as part of a multidisciplinary bundle.\r\n      <\/p>\r\n\r\n      <p>\r\n        In orthopedic ERAS, preoperative oral electrolyte-carbohydrate supplementation improved hunger, anxiety, weakness, and sodium balance without increasing complications.\r\n      <\/p>\r\n\r\n      <p>\r\n        In cardiac surgery, ERAS-oriented care emphasizes preoperative nutrition optimization, avoidance of unnecessary fasting, and early postoperative nutrition; a prospective observational study cited in the cardiac review suggested that an ERAS bundle after cardiac surgery improved postoperative morbidity, including nosocomial infection, acute kidney injury, respiratory failure, postoperative myocardial infarction, and hospital mortality.\r\n      <\/p>\r\n\r\n      <p>\r\n        In gastrointestinal cancer surgery, the interface between ERAS and preoperative immunonutrition is especially important; even within ERAS-style pathways, nutrition support appears to add benefit for infectious complications and length of stay in selected higher-risk patients. (1,5,7)\r\n      <\/p>\r\n\r\n      <p>\r\n        It is also important to avoid overstating ERAS nutrition effects. Carbohydrate loading alone does not uniformly reduce major complications across all procedures, and benefits may be more metabolic or experiential than mortality-related in some settings.\r\n      <\/p>\r\n\r\n      <p>\r\n        Likewise, immunonutrition should not be treated as universally indicated for every surgical patient. The strongest case is for risk-stratified implementation: use ERAS for all, but intensify perioperative nutrition therapy for those with malnutrition, sarcopenia, cancer, frailty, or expected prolonged postoperative inadequacy of intake.\r\n      <\/p>\r\n    <\/section>\r\n\r\n\r\n    <section id=\"evidence-table\">\r\n      <h2>Evidence on Nutrition and Surgical Outcomes<\/h2>\r\n\r\n      <div class=\"asante-article__table-wrap\">\r\n        <table>\r\n          <thead>\r\n            <tr>\r\n              <th>Population \/ Surgery<\/th>\r\n              <th>Nutrition Factor or Intervention<\/th>\r\n              <th>Key Outcomes<\/th>\r\n              <th>Practice Implication<\/th>\r\n            <\/tr>\r\n          <\/thead>\r\n\r\n          <tbody>\r\n            <tr>\r\n              <td>GI cancer surgery meta-analysis (16 studies;

Hospitals and surgical programs should implement routine preoperative malnutrition screening, rapid referral pathways for nutrition intervention, and ERAS-consistent nutrition protocols that include avoidance of prolonged fasting and early postoperative feeding.\r\n      <\/p>\r\n\r\n      <p>\r\n        High-risk groups\u2014including older adults, patients with GI cancer, frail cardiac surgery patients, and those with recent weight loss or poor intake, deserve intensified nutrition support before and after surgery. Where evidence is strongest, such as GI oncology and geriatric orthopedic populations, nutrition intervention should be considered part of risk reduction.\r\n      <\/p>\r\n\r\n      <p>\r\n        At the same time, nutrition care must remain individualized. Albumin alone is insufficient to diagnose malnutrition; obesity does not exclude sarcopenia or poor protein reserves; and no single intervention will benefit all operations equally.\r\n      <\/p>\r\n\r\n      <p>\r\n        The most defensible model is a tiered one: universal ERAS nutrition principles for all surgical patients, plus targeted medical nutrition therapy for those with measurable nutrition risk or disease states known to worsen postoperative outcomes.\r\n      <\/p>\r\n\r\n\r\n      <h3>Conclusion<\/h3>\r\n\r\n      <p>\r\n        The perioperative period is a window of both vulnerability and opportunity. Malnutrition increases postoperative complications, prolongs hospitalization, and in some surgical oncology settings is associated with worse long-term survival.\r\n      <\/p>\r\n\r\n      <p>\r\n        Conversely, structured perioperative nutrition care, especially when embedded within ERAS, can improve recovery trajectories and reduce preventable morbidity. For surgeons, anesthesiologists, and dietitians, the message is straightforward: better surgical nutrition care is better surgical care.\r\n      <\/p>\r\n    <\/section>\r\n\r\n\r\n    <section id=\"clinical-pearls\">\r\n      <h2>Practical Clinical Pearls<\/h2>\r\n\r\n      <ol>\r\n        <li>\r\n          <strong>Albumin is not a nutrition diagnosis.<\/strong>\r\n          Low albumin often reflects inflammation, illness severity, and surgical stress, and is not just poor intake.\r\n        <\/li>\r\n\r\n        <li>\r\n          <strong>Obesity does not exclude malnutrition.<\/strong>\r\n          Many bariatric, cardiac, and orthopedic patients have sarcopenic obesity with poor protein reserves.\r\n        <\/li>\r\n\r\n        <li>\r\n          <strong>Protein timing matters.<\/strong>\r\n          Distributing protein across meals (25\u201330 g per meal) is often more effective than one large dinner.\r\n        <\/li>\r\n\r\n        <li>\r\n          <strong>ERAS works best as a bundle.<\/strong>\r\n          Carbohydrate loading alone is helpful, but the strongest outcomes come when combined with screening, early feeding, mobility, and glycemic control.\r\n        <\/li>\r\n\r\n        <li>\r\n          <strong>Pre-op nutrition is \u201cprehabilitation.\u201d<\/strong>\r\n          Nutrition optimization should be treated like surgical preparation\u2014not an optional add-on.\r\n        <\/li>\r\n      <\/ol>\r\n\r\n\r\n      <h3>Practical Applications for Perioperative Nutrition Care &amp;

Asante Health October 1, 2026 6 min read In this article Summary Malnutrition, Nutrition Risk &amp; Adverse Surgical Outcomes Outcomes by Major Type of Surgery Enhanced Recovery After Surgery (ERAS) Evidence on Nutrition &amp; Surgical Outcomes Nutrition Components of ERAS Practical Clinical Pearls Summary Optimal nutrition care is not ancillary to surgery; it is part of surgical treatment. Across orthopedic, cardiac, gastrointestinal, oncologic, and general surgery populations, preoperative malnutrition and unrecognized nutrition risk are consistently associated with more postoperative complications, longer length of stay, higher resource utilization, and, in some populations, higher mortality. At the same time, evidence from systematic reviews and selected trials shows that targeted nutrition interventions, particularly early screening, oral nutrition supplements, immune-modulating formulas in selected gastrointestinal cancer patients, avoidance of prolonged fasting, carbohydrate loading where appropriate, and early postoperative feeding within Enhanced Recovery After Surgery (ERAS) pathways, can improve clinically meaningful outcomes. The central position of this paper is that nutrition should be operationalized as a routine perioperative quality and safety strategy. Surgical patients should be screened early for malnutrition risk, triaged for intervention, and managed with diagnosis-specific and procedure-specific nutrition plans integrated into ERAS workflows. Although the strength of evidence varies by surgical specialty and intervention, the aggregate literature supports three conclusions: first, malnutrition is common and prognostically important; second, single laboratory markers such as albumin should not be used in isolation to define nutritional status; and third, structured perioperative nutrition care can reduce complications and improve recovery, especially in higher-risk patients. (1-7) Malnutrition, Nutrition Risk, and Adverse Surgical Outcomes Malnutrition before surgery reflects both inadequate intake and the metabolic consequences of disease, inflammation, and catabolism. In practical terms, this means that weight loss, poor oral intake, loss of lean body mass, frailty, and disease burden often coexist. In elderly general surgery patients, a systematic review found that preoperative serum albumin and recent weight loss were the only parameters consistently linked with postoperative outcome, underscoring both the clinical importance of nutrition risk and the limitations of the available evidence base. The authors also noted that albumin is not a pure nutrition marker and likely reflects disease severity and inflammatory burden in addition to nutrition status. (3) This point is especially relevant for contemporary practice. More recent orthopedic evidence likewise cautions against relying on single biochemical measures alone. A 2026 meta-analysis of 11 studies including 201,338 geriatric orthopedic patients reported that malnutrition identified by nutrition screening tools was associated with a 65% higher risk of postoperative complications and more than double the risk of postoperative mortality. The signal was strongest in hip surgery populations, supporting the use of validated screening tools rather than isolated biomarkers in older adults. (6) From a nutrition and dietetics perspective, the implication is clear; perioperative nutrition assessment should move beyond albumin-only thinking. Weight history, recent intake, functional decline, body mass index, muscle loss or sarcopenia, and validated tools such as SGA, MUST, NRS-2002, MNA, GNRI, or procedure-specific risk frameworks provide a more clinically useful basis for identifying patients who need intervention. (3,5,6) Outcomes by Major Type of Surgery Orthopedic Surgery Orthopedic patients, particularly older adults with hip fracture or major joint replacement, have a high prevalence of nutrition risk because of age, inflammation, immobility, and acute catabolic stress. In hip fracture surgery, a meta-analysis of five randomized controlled trials including 654 geriatric patients found that preoperative protein-based oral nutrition supplements significantly reduced postoperative complications (OR 0.48, 95% CI 0.26\u20130.89), but did not significantly reduce in-hospital mortality or length of stay. The authors concluded that benefits were real but limited, which is consistent with the view that nutrition support improves morbidity more reliably than mortality in short, acute orthopedic episodes. (4) For elective arthroplasty, a randomized trial in elderly patients undergoing total knee arthroplasty found that a preoperative oral electrolyte-carbohydrate supplement improved subjective comfort, reduced hyponatremia, improved perioperative glucose-related outcomes, and reduced infusion volume without increasing complications. While this was not a malnourished cohort and did not demonstrate differences in major postoperative events, it supports ERAS-aligned nutrition practices such as minimizing prolonged fasting and using structured preoperative drinks in appropriately selected patients. (7) Cardiac Surgery Cardiac surgery presents a distinct nutrition challenge because of advanced age, multimorbidity, chronic heart failure, inflammation, and postoperative critical care needs. A narrative review of adult cardiac surgery concluded that malnutrition is associated with longer ICU stay, longer mechanical ventilation, more cardiovascular and infectious complications, and postoperative delirium after CABG. Reported prevalence of malnutrition or nutrition risk ranged widely, from 1.2% to 46.4%, reflecting inconsistent definitions and tools. (5) The cardiac surgery literature supports routine preoperative screening, aggressive attention to protein-energy adequacy, and early enteral nutrition when oral intake is not feasible. It also highlights the need to identify sarcopenia, frailty, and cachexia rather than focusing only on body weight. The practical takeaway is that nutrition in cardiac surgery should be embedded in prehabilitation and ERAS-style perioperative care bundles, with special attention to avoiding unnecessary fasting and initiating postoperative feeding early when clinically appropriate. (5) Gastric and Other Gastrointestinal Cancer Surgery The evidence is especially strong in upper gastrointestinal and oncologic surgery, where baseline malnutrition is common and biologically plausible as a driver of poor wound healing, infection, and reduced tolerance of treatment. In a large study of 1,976 patients undergoing radical gastrectomy, malnourished patients had a significantly higher overall complication rate than well-nourished patients (21.4% vs 15.5%), as well as worse 3-year overall survival (59.1% vs 75.0%) and disease-free survival (54.8% vs 72.5%). Malnutrition was an independent predictor of both overall and disease-free survival. Among malnourished patients with stage II\u2013III disease, correction of preoperative hypoproteinemia was associated with improved 3-year overall survival and disease-free survival, suggesting that nutrition optimization before surgery may affect not only short-term recovery but also longer-term oncologic resilience.

Asante Health October 1, 2026 6 min read In this article Summary Malnutrition, Nutrition Risk &amp; Adverse Surgical Outcomes Outcomes by Major Type of Surgery Enhanced Recovery After Surgery (ERAS) Evidence on Nutrition &amp; Surgical Outcomes Nutrition Components of ERAS Practical Clinical Pearls Summary Optimal nutrition care is not ancillary to surgery; it is part of surgical treatment. Across orthopedic, cardiac, gastrointestinal, oncologic, and general surgery populations, preoperative malnutrition and unrecognized nutrition risk are consistently associated with more postoperative complications, longer length of stay, higher resource utilization, and, in some populations, higher mortality. At the same time, evidence from systematic reviews and selected trials shows that targeted nutrition interventions, particularly early screening, oral nutrition supplements, immune-modulating formulas in selected gastrointestinal cancer patients, avoidance of prolonged fasting, carbohydrate loading where appropriate, and early postoperative feeding within Enhanced Recovery After Surgery (ERAS) pathways, can improve clinically meaningful outcomes. The central position of this paper is that nutrition should be operationalized as a routine perioperative quality and safety strategy. Surgical patients should be screened early for malnutrition risk, triaged for intervention, and managed with diagnosis-specific and procedure-specific nutrition plans integrated into ERAS workflows. Although the strength of evidence varies by surgical specialty and intervention, the aggregate literature supports three conclusions: first, malnutrition is common and prognostically important; second, single laboratory markers such as albumin should not be used in isolation to define nutritional status; and third, structured perioperative nutrition care can reduce complications and improve recovery, especially in higher-risk patients. (1-7) Malnutrition, Nutrition Risk, and Adverse Surgical Outcomes Malnutrition before surgery reflects both inadequate intake and the metabolic consequences of disease, inflammation, and catabolism. In practical terms, this means that weight loss, poor oral intake, loss of lean body mass, frailty, and disease burden often coexist. In elderly general surgery patients, a systematic review found that preoperative serum albumin and recent weight loss were the only parameters consistently linked with postoperative outcome, underscoring both the clinical importance of nutrition risk and the limitations of the available evidence base. The authors also noted that albumin is not a pure nutrition marker and likely reflects disease severity and inflammatory burden in addition to nutrition status. (3) This point is especially relevant for contemporary practice. More recent orthopedic evidence likewise cautions against relying on single biochemical measures alone. A 2026 meta-analysis of 11 studies including 201,338 geriatric orthopedic patients reported that malnutrition identified by nutrition screening tools was associated with a 65% higher risk of postoperative complications and more than double the risk of postoperative mortality. The signal was strongest in hip surgery populations, supporting the use of validated screening tools rather than isolated biomarkers in older adults. (6) From a nutrition and dietetics perspective, the implication is clear; perioperative nutrition assessment should move beyond albumin-only thinking. Weight history, recent intake, functional decline, body mass index, muscle loss or sarcopenia, and validated tools such as SGA, MUST, NRS-2002, MNA, GNRI, or procedure-specific risk frameworks provide a more clinically useful basis for identifying patients who need intervention. (3,5,6) Outcomes by Major Type of Surgery Orthopedic Surgery Orthopedic patients, particularly older adults with hip fracture or major joint replacement, have a high prevalence of nutrition risk because of age, inflammation, immobility, and acute catabolic stress. In hip fracture surgery, a meta-analysis of five randomized controlled trials including 654 geriatric patients found that preoperative protein-based oral nutrition supplements significantly reduced postoperative complications (OR 0.48, 95% CI 0.26\u20130.89), but did not significantly reduce in-hospital mortality or length of stay. The authors concluded that benefits were real but limited, which is consistent with the view that nutrition support improves morbidity more reliably than mortality in short, acute orthopedic episodes. (4) For elective arthroplasty, a randomized trial in elderly patients undergoing total knee arthroplasty found that a preoperative oral electrolyte-carbohydrate supplement improved subjective comfort, reduced hyponatremia, improved perioperative glucose-related outcomes, and reduced infusion volume without increasing complications. While this was not a malnourished cohort and did not demonstrate differences in major postoperative events, it supports ERAS-aligned nutrition practices such as minimizing prolonged fasting and using structured preoperative drinks in appropriately selected patients. (7) Cardiac Surgery Cardiac surgery presents a distinct nutrition challenge because of advanced age, multimorbidity, chronic heart failure, inflammation, and postoperative critical care needs. A narrative review of adult cardiac surgery concluded that malnutrition is associated with longer ICU stay, longer mechanical ventilation, more cardiovascular and infectious complications, and postoperative delirium after CABG. Reported prevalence of malnutrition or nutrition risk ranged widely, from 1.2% to 46.4%, reflecting inconsistent definitions and tools. (5) The cardiac surgery literature supports routine preoperative screening, aggressive attention to protein-energy adequacy, and early enteral nutrition when oral intake is not feasible. It also highlights the need to identify sarcopenia, frailty, and cachexia rather than focusing only on body weight. The practical takeaway is that nutrition in cardiac surgery should be embedded in prehabilitation and ERAS-style perioperative care bundles, with special attention to avoiding unnecessary fasting and initiating postoperative feeding early when clinically appropriate. (5) Gastric and Other Gastrointestinal Cancer Surgery The evidence is especially strong in upper gastrointestinal and oncologic surgery, where baseline malnutrition is common and biologically plausible as a driver of poor wound healing, infection, and reduced tolerance of treatment. In a large study of 1,976 patients undergoing radical gastrectomy, malnourished patients had a significantly higher overall complication rate than well-nourished patients (21.4% vs 15.5%), as well as worse 3-year overall survival (59.1% vs 75.0%) and disease-free survival (54.8% vs 72.5%). Malnutrition was an independent predictor of both overall and disease-free survival. Among malnourished patients with stage II\u2013III disease, correction of preoperative hypoproteinemia was associated with improved 3-year overall survival and disease-free survival, suggesting that nutrition optimization before surgery may affect not only short-term recovery but also longer-term oncologic resilience.
