Malabsorption Disorders<br><\/strong> Conditions like celiac disease prevent proper absorption of vitamins, proteins, and fats. Frequent meals may still fail to meet the body\u2019s nutritional needs.<\/p>\n\n\n\n<p><strong>2. Inflammatory Bowel Disease (IBD)<br><\/strong> Chronic inflammation from Crohn\u2019s disease or <a href=\"https:\/\/luxhospitals.com\/treatments\/proctology\/ulcerative-colitis\/\"><mark style=\"background-color:rgba(0, 0, 0, 0);color:#0693e3\" class=\"has-inline-color\"><strong>ulcerative colitis<\/strong><\/mark><\/a> causes pain, diarrhoea, and calorie loss.<\/p>\n\n\n\n<p><strong>3. Chronic Gastrointestinal Infections<br><\/strong> Infections such as H. pylori can reduce appetite, cause nausea, and interfere with digestion.<\/p>\n\n\n\n<p><strong>4. Pancreatic Disorders<\/strong><strong><br><\/strong> The pancreas produces enzymes essential for digestion. Reduced enzyme production leads to poor food breakdown and weight loss.<\/p>\n\n\n\n<p><strong>5. Digestive Tract Cancers<\/strong><strong><br><\/strong> Gastrointestinal cancers can alter metabolism and reduce food intake.
