Hello, The issue of abdomen cramps after diverticulitis surgery and colostomy reversal is related to possible intestine transit time problems with propulsive movements being sluggish to the extent needed for bowel evacuation. Apart from antacid and fiber intake I would suggest: - Plenty of liquids - High fiber diet - Prokinetic drugs as Itopride - Digestive enzymes as Enzar forte or Pancreatoflat to aid in the digestion process - Dietary precautions as to avoid all spices, non veg, junk items, dairy fat products - Control of body weight - Control of blood sugar and cholesterol - Regular walking, exercises, aerobics - Avoidance of smoking or alcohol if consuming (which will dampen the intestine activity) - Avoidance of stress and anxiety Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Bhagyesh V. Patel, General Surgeon
