Yeah, so you find yourself getting loose stool? Diarrhea? Here is one quick solution. Just make yourself an ORS solution to rehydrate yourself. Because you see, when you catch loose stool, you will lost body fluid and electrolytes that mantain your body homeostasis ie you get dehydrated. So, to come back normal, you have to (read loudly; HAVE TO) rehydrate yourself.
Here is the guide:
6 teaspoons of sugar
1/2 teaspoon of salt
1 litre of water (about 5 full cups. Use warm water to dissolve easily )
Just mix and stir until they dissolve. And then you drink it. Not all, of course. 1 cup is enough. Also, you can eat banana as it contain potassium. (Phew, luckily, I eat banana)
