Hi,
I can recommend a home remedy for constipation that my mom always gave me. I'm 78 and still use it. It's natural and works well. However, it only works when you take it. It's not like taking laxatives or medications everyday. It's a teaspoon or more if needed, of baking soda (the kind you cook with – Arm and Hammer) dissolved in a glass of water. Drink the whole glass. You may want to squeeze a little lemon juice in it to make it taste better. It tastes awful, but it works. Stay near the bathroom. It works fairly fast and will get rid of your constipation. Once it works it is done. It won't work again until you take it. That way, you may be able to not have diarrhea continually. It also helps get rid of gas and bloating. After it works, try and drink a lot of water to keep from being dehydrated.
I hope this helps!
