Short bowel syndrome happens when too much small intestine is missing or removed. With less surface to absorb food and water, symptoms hit fast after every meal.

Watery diarrhea is the hallmark. Stools are loose, frequent, and often look like pale soup.

Weight loss is rapid. Clothes loosen even when you eat more, because calories slip through unabsorbed.

Dehydration loops back. You feel thirsty, dizzy, and lips dry out despite drinking often.

Cramping and bloating strike after eating. Gas pains build quickly and ease only after stools pass.

Fatigue is constant. Low nutrients and low potassium make muscles feel heavy and brain foggy.

Late signs include skin breakdown, hair loss, or ankle swelling—an alarm that vitamins and protein are too low.
