Weight-Loss Drugs (Diet Pills)
Wouldn't it be nice if you could just take a pill and lose weight? Well there are pills to help you diet but you still have to eat less. There are two types of diet drugs. One you can buy without a doctor's prescription and these are called over the counter (OTC) drugs and another kind your doctor has to prescribe.
The most common types of pills work on the appetite center in your brain which is called the hypothalamus. The two most common drugs are Sibutramine which raises the appetite chemical serotonin in the brain and Rimonabant which stops the receptors in the brain working (this is only used in Europe). The side effects of both drugs may include high blood pressure and a rapid heart rate and Rimonabant could also cause anxiety and depression. Most people who took diet pills did not lose much weight after 4 to 6 months (the average weight loss was about 11lbs) but it helped lower their blood pressure, cholesterol levels and diabetes.
The other prescription drug works on your intestines by stopping fat absorption. If you eat too much fat while you are taking the drug you get gas and diarrhea. Common drugs are Xenical, Orlisat or Alli. It is also sold OTC (over the counter) at a lower dose.
Over the counter drugs work on many different systems but some are fake and don't work at all. Some have green tea extract or caffeine which increase your heart rate and give you more energy.
Amphetamines used to be used for diet pill as they decreased appetite. These medications can be addictive so they are rarely used for weight loss now.
