Can caffeine pills upset your stomach?

I used to take diet pills off and on for a while and they can cause an upset stomach, it all depends on the person. They can be very dangerous also, I stopped taking them because they caused me to lose a lot of hair. Just a warning.

AnswerYou need to make sure you take a good diet pill, one that is natural organic, it can have low levels of caffeine and ephedra. Ephedra isn't the devil its made out to be when taken correctly. People abused it and that caused some problems.

Everyone reacts differently to Diet pills some people love them. Alli is FDA approved but people have the liquid runs the entire time. Zylene is a great diet pill that is natural and organic with little to no side effects depending on the person. Green tea is great but is better in combination with other supplements. Hoodia isn't bad, chromium helps but overall not every diet pill will effect people the same way. Some people take these pills for months and have no problems and others for days and cant get off of the toilet.
