Can diarrhea cause weight gain?

I've been struggling with recurrent bouts of diarrhea for a few months now, and strangely, I feel like I'm gaining weight instead of losing it. Is it possible for diarrhea to actually cause weight gain? It feels very counter-intuitive.

Directly, no, you actually lose water weight during diarrhea. But what happens is, once you recover, you might crave heavy carbs or salty foods to make up for the weakness, which can lead to temporary water retention and bloating. Focus on eating clean, small meals post-recovery to avoid this.

Physiologically, diarrhea causes dehydration and loss of fluids, which shows up as weight loss on the scale initially. If you see the scale jump up right after, it is usually just your body holding onto water as you rehydrate. Don't worry, just stick to your normal macro-friendly diet once your gut is back to normal.

Diarrhea se directly weight gain toh nahi hota na, balki body ka saara pani nikal jata hai. Haan, recovery ke time jab hum khoob saara liquid aur electro powder peete hain, toh temporary bloating lag sakti hai. Isko asli fat gain mat samjho, body bas recover ho rahi hai.

Oh, definitely not! Diarrhea usually drains you out completely. If you feel heavier, it might just be gas or bloating from the stomach infection. Drink some coconut water and let your digestion settle down first!

Hey, don't worry about the scale right now. Diarrhea makes you lose a lot of water and electrolytes, and when you start eating again, your body naturally retains fluids to heal itself. Focus entirely on getting your strength back first, the weight will stabilize on its own.

If you are experiencing unexplained swelling or sudden weight gain along with diarrhea, please consult a doctor. When I had severe gut issues, my body started retaining water abnormally due to kidney strain from dehydration. It is always safer to get your kidney function and electrolyte levels checked.
