Diarrhoea on planes? Immodium even if you don’t have diarrhoea?
Yup you can, and in my experience it is advisable. a lot of times I will take immodium way before I even have diarrhea because I just have that feeling my stomach is upset and I might have problems later. Immodium basically slows your digestive system down. This slowing down allows the food in your digestive tract to pass more naturally through your intestines and obtain more water making it less runny and more solid (like normal poop) It takes time though, it won't immediately work. My experience is to take one even if i don't have diarrhea but just a slight stomach ache or a feeling I might have a problem later on, then throughout the day you can take some more if it gets worse.
Yes it's safe to take Imodium beforehand if you're worried. Many people do.
Normal with IBS. Meditation helps and drinking plenty of fluids, potassium intake as well as bananas.
