Treatment is directed largely towards management of underlying cause: * Replacement of nutrients, electrolytes and fluid may be necessary. In severe deficiency, hospital admission may be required for nutritional support and detailed advice from dietitians. Use of enteral nutrition by naso-gastric or other feeding tubes may be able to provide sufficient nutritional supplementation. Tube placement may also be done by percutaneous endoscopic gastrostomy, or surgical jejunostomy. In patients whose intestinal absorptive surface is severely limited from disease or surgery, long term total parenteral nutrition may be needed. * Pancreatic enzymes are supplemented orally in pancreatic insufficiency. * Dietary modification is important in some conditions: * Gluten-free diet in coeliac disease. * Lactose avoidance in lactose intolerance. * Antibiotic therapy to treat Small Bowel Bacterial overgrowth. * Cholestyramine or other bile acid sequestrants will help reducing diarrhoea in bile acid<unk> .
