How is it possible that diet pills work when most drs swear they don't? a friend used them & lost weight! are they harmful? will she suffer later?thnx

It all depends: It's clear some diet pills have temporary benefits. There are many types of diet pills that work via suppressing appetite or speeding metabolism. Some can have serious side effects such as heart damage but some are relatively safe. I can't comment about your friend's risk without knowing what she used. The problem most docs have is weight loss from diet pills tends to be temporary. See comment:.

They work. But...: Diet pills (appetite suppressants) work. But with time u need to keep taking more ; more of pills to get same appetite suppressing effect as initially. U can keep raising the dose to maintain your weight loss. But before u know it, u will be addicted to them, and they will start causing you insomnia, irritability, poor concentration and heart problems. So docs r right to advise against.
