do I even NEED a cleanse?

Sorry in advance for TMI...

I've been thinking about doing a master cleanse... and researching everything.. and I guess I want to know if I even NEED a cleanse?

I had my gall bladder out over 10 years ago. (biggest mistake of my life.. ) anyway.. since then, because of the surgery... I have had explosive diarhea 2-5 times a day EVERY SINGLE DAY... nothing but water, and mostly undigested food. You would think that I would be about 80 pounds by now.. but,I'm not... I'm about 75 pounds over weight...

With having diarhea for sooo many years.. would I even HAVE anything built up in my digestive tract to cleanse? would it even be worth my while to do this?
