People who are obese and have difficulty in losing weight through exercise and diet without results are ideal candidates to use drugs to lose weight. People who are also unable to lose weight due to injuries and ailments may use them. Though how much of weight lost varies in individuals but people usually lose 5%-10% of their body weight. Approved by the FDA in 1999, Xenical is the first in amongst anti-obesity drugs available and known as lipase inhibitors. Lipase is an enzyme that breaks down dietary fat for use in the body. Xenical interferes with lipase function by decreasing dietary fat absorption to at least by 30 percent since the undigested fats are not absorbed hence fewer calories are available to the body. This helps to control weight. The only and mild side effects of Xenical are cramping, diarrhea, flatulence, intestinal discomfort, and oily stool. For some people they don’t even feel the side effects.
Another drug, Meridia (sibutramine), approved by the FDA in 1997, helps by increasing the levels of some brain chemicals that reduce the appetite. Meridia may elevate blood pressure and heart rate hence should not be used by people with high or low or uncontrolled high blood pressure, people with history of heart diseases, congestive heart failure, irregular heartbeat, or if people have suffered stroke. Other common side effects of Meridia are headache, dry mouth, constipation and insomnia. The Meridia pill is available as in 5mg, 10mg and 15mg doses. It is administered orally and is prescribed to be taken with or without food and usually in the mornings. Like other pills to lose weight Meridia weight loss is prescribed for the heavily obese. Your BMI should be over 30 or you could have lower BMI of 27 with other obesity related disease like high blood pressure and diabetes.
It must be used in conjunction with a healthy weight loss diet and exercise if you are able to do. Meridia is used for a short term use and to jump start a weight loss program for starting other motivation factors. The Meridia weight loss drug is commonly called sibutramine which is a chemical preparation that helps by stimulating the nervous system. It is known to restrict the re-uptake of particular brain chemicals like serotonin and dopamine.
Side effects of Meridia
Meridia shows typical side effects. Some of the side effects are:
- Change in taste percestian
- Sleeping disorders
- Stuffy nose
These effects either go away or fade away as the body gets used to the drugs. "There is no magic pill for obesity," says David Orloff, M.D., director of the FDA's Division of Metabolic and Endocrine Drug Products. "The best effect you're going to get is with a concerted long-term regimen of diet and exercise. If you choose to take a drug along with this effort, it may provide additional help."
Losing weight may seem difficult at first but you will slowly get used to it and once you see the results the motivation factors will increase resulting in more weight loss. Weight loss is tough but not impossible, don’t give up before you try and the results you achieve will be worth it.
