Obesity - is a disease that is manifested with the excess development (growth) of fat tissue. Obesity became a serious problem for people in developed countries. According to the data, about 30 % of population suffer from excess body weight. It is usually observed in women over 40 years old.

Obesity is a severe disease that can lead to different health problems such as heart attacks, stroke diabetes and hormonal disturbances. It is known that an excess body weight by 10% increases death rate in average by 30%.

Many people spend millions of dollars on all types of weight loss programs. However, very often the treatment becomes vain. That's why it is very important to determine what exactly has led to obesity. In most cases the cause is overeating. It means that our body obtains more calories from eating and does not burn them properly. These calories are deposited in the form of fat tissue. As a result we have excess body weight. There is a number of possible risk factors such as genetic disposition, hormonal disbalance , drug or alcohol abuse. All of these can increase your chance for obesity.

The right weight loss treatment must include the complex of corresponding approaches. These may be:

• Weight loss program that includes right nutrition, diet and physical exercises.
• Prescription weight loss pills
• Non-prescription weight loss medicines
• Wight loss surgery

Many companies offer "best way" or "magic weight loss pills" against obesity. It is important to know that none of the produced weight loss drugs can rapidly decrease your body weight. Only a small number of drugs in combination with good weight loss programs can help people who suffer from obesity. All weight loss pills can be divided into some groups according to their action:

Appetite suppressants such as Phentermine (Adipex-P), Sibutramine (Meridia), Phendimetrazine (Bontril PDM, Plegine) , Diethylpropion (Tenuate, Tepanil) , Methamphetamine(Desoxyn) , Benzphetamine (Didrex). They work by blocking the specific chemicals in your brain that effect appetite and mood. As a result the appetite is decreased. These drugs are effective only in combination with right nutrition and physical exercises. It means that if you eat fatty foods and don't have enough physical activity appetite suppressants will not help you reduce excess body weight. Appetite suppressants can cause a lot of side effects. These can be headache, irritability, insomnia, anxiety, increased heart beat and pain in heart area. That's why the treatment must be under your health care providers control.

Lipase inhibitors: Xenical(orlistat). It works by inhibiting digestive enzymes: pancreatic and intestine lipase. Lipase breaks down dietary fat, helping body to absorb them into the blood stream. When lipase is blocked, fats can not be absorbed. It gives the possibility to reduce calories getting with food. Orlistat doesn't affect the protein and carbohydrate absorption. Xenical is not effective without a diet with reduced level of fats and increased physical activity. There is a number of possible side effects that can occur while taking orlistat: stomach pain, gas, diarrhea, oily stool and others.

Ballast substances can swell in stomach, making illusion of satiation. People consume less food therefore fewer calories get into human organism. These drugs are sold under the brand names: Lida, Teo Nova Figura, Ankir-B, Evalar.

Water pills and laxatives can also be used in the complex treatment of obesity. However, the effectiveness of these weight loss pills is not high.

There is a big number of off-label weight loss pills. These may be antidepressants, diabetes drugs, epilepsy medications. These drugs are used to treat depression, diabetes and mental disorders that are the risk factors for excess weigh loss. Only your health care provider can prescribe you these medicine.

People who suffer from obesity should not only rely on any of these drugs. Social support, will-power and sometimes corresponding psychotherapy give more effective results.
