Most Americans are now defined as overweight or obese. Millions are trying to lose weight, and there are many ways to try to do this. The most basic way to lose weight is through strict discipline of diet and exercise, but many are unwilling or unable to commit to such a program. Surgery is another option, but risks and complications scare many people. This has created great interest in prescription medications for weight loss
These are drugs that suppress appetite, so you do not feel hungry. You take in fewer calories, and the body begins to burn fat for energy. Prescription appetite suppressants include Tenuate, Didrex, Sanorex, Adipex-P, Mazanor and Meridia. Apart from Meridia, are appetite suppressants are not meant to be taken for a longer period. They are short-term medications.
Fat Absorption Inhibitors
Fat absorption inhibitors are drugs that prevents the body digest fats in the foods you eat. This fat is then eliminated from the body through the intestines. The only known fat absorption inhibitor is Xenical, which is capable of preventing the absorption maximum of about 30 percent of the fat in the diet. (The over-the-counter medication Alli is a lower dose of orlistat, the active ingredient in Xenical.)
Make Weight Loss Prescription Work?
In general we can say that these drugs work. On average, people who use Xenical and Meridia (the only long-term weight-loss prescriptions in USA) lost 5-22 pounds after one year. However, the success of these medications on how they are tolerated by the body. Some people lost more weight than others after taking the same doses. Dosage depends on the evaluation by your doctor.
People taking appetite suppressants may experience increased heart rate and blood pressure, constipation, inability to sleep, drowsiness, headache and sweating. Xenical can cause an inability to control bowel movements, which means that you need to use the bathroom more often. Because it inhibits fat absorption, lead Xenical oily stools, oily discharge and spotting. These conditions are aggravated by eating fatty foods.
Some of these drugs can be addictive, especially those for long-term use. Xenical and Meridia are controlled drugs, and doctors should follow guidelines when prescribing them. The body can increase tolerance to these drugs, so you need to take more to get the same results. This further increases the risk of addiction.
