Diet pill aka appetite suppressant is a dietary supplement and/or drug which reduces appetite, food consumption, and as a result, causes weight loss to occur. Prescribed diet pills are usually prescribed to patients who suffer from serious obesity which can cause serious health problems and even lead to death. These drugs work on chemicals inside the brain in order to partially suppress appetite. As with any brain-regulating drug, these powerful appetite suppressants may cause serious and unforseen side effects like pulmonary hypertension, damaged heart valves, tachycardia, insomnia, diarrhea, blurred vision, headache, stomachache, nausea or vomiting etc.
