In other words, all kinds of diet pills used now have some adverse reactions to some extent. Patients who take such drugs are likely to lose weight while spending money, which also does harm to their health. For example, a study conducted in the United States in 1997 found that fenfluramine, once a popular appetite inhibitor, may damage the function of patients' heart valves and lead to sudden death. From June 5438 to 10, 2000, the Federal Food Hygiene Administration (FDA) issued a warning that drugs containing amphetamine may lead to an increase in the incidence of stroke in patients. Amphetamines are widely used in diet pills and cold medicines.
