Does diarrhea cause weight loss?

I've had a bad bout of stomach flu for the last couple of days, with constant diarrhea. I've noticed I've lost a bit of weight. Does diarrhea typically cause weight loss, or is it mostly just water loss?

It can cause a temporary drop on the scale because the body loses water. Stay positive, keep your mind calm, and let your body heal naturally with pure, simple food.

The weight loss you see after diarrhea is almost entirely water weight and fluid loss, not actual fat loss. It usually comes right back once you are rehydrated and back to your normal diet, so focus on recovery.

Yeah, I lost like 2 kgs after a bad stomach infection last semester, but it was just dehydration. Once I started eating normal hostel food again, the weight came back in two days.

It definitely makes the scale go down temporarily because you lose so much water! Just focus on getting better first with lots of fluids and rest. 🌸

It causes sudden weight loss because of severe water depletion. Please don't try to restrict food to maintain this loss; instead, eat soft vegetarian options like boiled rice or banana to regain your strength.

It might show a lower weight, but it's not healthy weight loss at all. Especially with hormonal issues, dehydrating yourself can cause other imbalances, so please focus on proper nutrition and hydration.
