A diet pill or weight lose drug refers to all pharmacological agents that reduce or control a person’s weight.
These drugs alter one of the fundamental mechanisms of the body, which is weight regulation. This happens by either altering appetite, metabolism or the absorption of calories.
Most people try them and if there is no positve result discontinue them. Because of the potential side effects it should only be prescribed in the event of obesity where maybe the benefits could outweigh the risks.
Diet pills operate through one or more of the following routes:
Suppression of the appetite:
Catecholamines and there derivatives are the main weapons used for this. Drugs blocking the cannabiniod receptors may be the future strategy for appetite suppression.
Increase in the body’s metabolism
Interference with the body’s ability to absorb diffent nutrients in food.
Anorexics are intended to suppress the appetite, but most drugs in this category tend to act like stimulants.
