Xenical - Mechanism of action and side effects

Orlistat, commercially sold as Xenical is a prescription drug used for the treatment of obesity. It is also known as tetrahydrolipstatin. It works by preventing the absorption of fat from your diet. This medication is known to give the best results when it is used in conjunction with a low-calorie diet and exercise. On the whole, it is an effective obesity treatment.

How Xenical works

Most of the obesity treatments and therapies insist that people go on a rapid weight loss diet, which can be highly unsafe, as your body is deprived of the essential nutrients. Dieting is bad for health. Conventional weight loss drugs either suppress your diet or increase the rate of your metabolism. This affects your health adversely. You should never choose a weight loss method that damages your body.

On the other hand, Xenical is a well researched drug that has a completely new approach to weight loss. It blocks almost one-third of the dietary fat, which you have eaten, from being digested. Weight gain is caused because your body stores the excess amount of fat that is consumed. Once you eat food, it is broken into simple components that can be easily absorbed by your body. Xenical inhibits this process thereby helping with weight loss.

Possible side effects

Xenical has some side effects, but it is not necessary that all those who take this drug will experience problems. It suits most people quite well. In case you experience side effects, please contact your doctor at the earliest. Xenical takes effect in your digestive system and therefore does not affect the other parts of your body in any way. It's side effects include:
  • Oily spotting
  • Gas with small amounts of oil
  • Fatty stool
  • Nausea
  • Back pain
  • Headache
  • Fatigue
Many side effects related to the digestive tract can be reduced by decreasing your intake of dietary fat. Many weight loss pills are available on the market which aid in reduction of weight. However, Xenical is the most effective pill.
