Diet pills are not health products, but medicines, which have certain side effects and adverse reactions. To lose weight through diet pills, it takes a long time to achieve the purpose of slimming. However, taking diet pills for a long time will cause gastrointestinal dysfunction, which may lead to indigestion in light cases and a series of gastrointestinal diseases in severe cases. Some diet pills are even harmful to the human body. For example, some diet pills contain diuretics, which will lead to the deterioration of renal function and cause various diseases. In particular, women taking diet pills can also lead to infertility, which is very bad for every woman and will become a lifelong regret. Therefore, in order to be healthy, we should lose weight scientifically. For example, reasonable diet, balanced nutrition and more exercise.
