Obesity as such is defined as a disease by the medical community. Though there are certain theories on what causes obesity there has been no concrete proof of it. Thus the theories related to the obesity are vague in nature. To move out of obesity there can be no better method than the age old theory of controlled dieting and physical exercises. But the process is time consuming so many a people leave it for the sake of other options like diet pills, fat burning pills, surgery, liposuction, acupressure and acupuncture. Eating habits, lack of exercises, general lethargy and heredity are considered to be some the important factors which contribute to form fat inside your body. Fat burning pills are for short term use only and if you discontinue it the fats come up again. Surgery and liposuction are costly plus the effects of it are limited. With acupressure and acupuncture the results have not been up to the mark. So, the best option left is the combination of diet pill with restricted diet program and physical exercises. And the latest weight loss diet pill is Acomplia (Rimonabant). It has been developed by Sanofi-Aventis. It is does not make one loose weight rather it makes him to have a low appetite. And as appetite gets lower his food intake too lowers. Acomplia is a new kind of drug named CB1 blocker. It blocks CB1 receptors in the brain and in near by organs which are important for lipid and glucose metabolism, adipose tissue, gastrointestinal tract, and the liver. CB1 receptor plays a vital role in regulating body weight and controlling energy balance. Acomplia (Rimonabant) is now available for sale in the UK and EU but it is not available for sale in US as it has not been approved by FDA. Though the manufacturer of Acomplia (Rimonabant) instruct of taking a pill a day, the instruction of a doctor should be followed in case of its medication. Pregnant women, breast feeding women and children should avoid this medicine unless prescribed by the doctor. An individual with a history of blood pressure, heart disease, lung disease, asthma, diabetes or allergy must tell his medical history to the doctor. Acomplia has mild and short-term side effects like – nausea, dizziness, depression and irritability. As the drug is new other side effect too may come up. In case of side effects one should consult his or her doctor. He is the right person to advice you in that regard. No medicine has been useful in treating a disease unless instructions are followed. That applies in case of Acomplia too. It is only the exercises and restricted diet which will guide you to a bright and healthy future. Acomplia is only for fastening the pace of the weight loss.
