Obesity is one of the challenging health conditions most people (especially women) have to deal with, and you certainly need to do so. The impact of obesity on your body and body systems is, in simple terms, risky. The diseases associated with obesity are not only life threatening but also difficult to treat or manage in addition to being very expensive to treat. You certainly do not wish to take drugs for the rest of your life. Because of how obesity can be destructive, various treatments have been developed. These include dieting plans and physical exercises. In addition to these, varied anti-obesity medications have also been availed into the market for the same purpose.
Anti-obesity medications have so far attracted varied opinions from different experts regarding their safety. While some proponents of the same have continuously encouraged those obese to use the drugs, opponents have pointed out the dangers or side effects of using the same. One fact is however certain that most of the anti-obesity medications have not been subjected to requisite efficacy tests as is required of medications for human use. Any medication whose safety is in question definitely makes it unsafe. This means that the only safe ways of fighting obesity (as of now) remains safe dieting and physical exercises.
How Anti-Obesity Medications Work?
Anti-obesity medications act through three main mechanisms:
- Appetite suppression – The drugs produce the same effect as smoking tobacco or marijuana. They suppress your appetite for food. They eliminate hunger, making you feel that you are full. This enables your body to avoid buildup of fat in your body with your body resorting to using any fat stored within for energy purposes. This enables you to reduce your weight drastically.
- Increased metabolism – The drugs increase your body’s metabolism process. Any food you eat is processed fast and any absorbed nutrients including fat is used up fast, avoiding buildup of the same.
- Restricted absorption of nutrients – The drugs restrict responsible cells from absorbing particular nutrients contained in the food that you eat, including fat.

You need to be very careful before you use any anti-obesity medication. In most cases, the side effects of these medications (which can be life threatening) outweigh any benefits you may derive. The fact that most of them have not been approved by reputable health authorities and health regulatory agencies should restrict you to dieting and exercising as the safest ways of fighting obesity. Anti-obesity drugs are certainly not safe (yet).
