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 positive 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 different nutrients in food.
Anorexics are intended to suppress the appetite, but most drugs in this category tend to act like stimulants.
Here are the best diet pills on the market:
Orlistat:
This diet pill reduces intestinal fat absorption by inhibiting pancreatic lipase. This diet pill is originally available by prescription. it has now been approved by the FDA as an over the counter sale since February 2007. the pill may cause frequent oily bowel movements if there is a lot of fat in the diet.
Sibutramine:
Is an anorectic or appetite suppressant, it reduces the desire to eat. The diet pill may high blood pressure and may cause dry mouth, insomnia, headache, and constipation
Metformin:
If a person has diabetes this diet pill can reduce weight.
Rimonabant:
This is a recently developed diet pill and it usually acts centrally on the brain and thus reduces appetite. they not only cause weight loss but they prevent or reverse the metabolic effects of obesity.
Exenatide:
This drug delays gastric emptying and promotes a felling of satiety. not all patients experience substantial weight loss while on the diet pill. Therefore it is recommended only for diabetic patients.
Pramlintide:
This drug also delays gastric emptying and promotes a feeling of satiety. again it is usually prescribed for diabetic patients.
Some diet pills have life threatening side effects. these side effects are associated with their mechanism of action. In general stimulant carry a risk of high blood pressure, increased heart beat, glaucoma, drug addiction and insomnia.
One of the best diet pills on the market Orlistat blocks the absorption of dietary fat, and as a result may cause oily bowel movements.
If I was to recommend Orlistat as one of the best diet pills on the market i would say yes. At least it has the least side effects.
