There are many weight loss drugs that are sold in the market. But according to research by scientists, there is no single drug that are really safe because almost all of them have risks.
For centuries scientists had tried to discover anti-obesity drugs, but still fails. Until today, drugs have not became an effective answer to the problem of being overweight or obese, despite the reality that billions of dollars have been spent on researches.
Based on a research, it is known that obesity is not just a factor of too much eating but have various causes. Because of that, it is not possible that one drug can overcome the factors.
“We have no miracle drug for obesity, we may have to use a ‘bomb’ which is very comprehensive,” said Dr. Gene-Jack Wang, head of medical research at Brookhaven National Laboratory, according to CNN.
Meanwhile, Dr. Sidney Wolfe, director of the Health Research Group said she did not expect there will be a weight loss drug that is effective and safe. Because according to her the possibility to obtain drug without a a lot of side effects to the body is zero.
Some examples of weight loss drugs which are known to have side effects are:
- Prescription drugs by speeding up metabolism can lead to stroke, heart attack and cardiovascular problems.
- Drugs that functions to block the body from absorbing fat can cause unpleasant side effects like diarrhea.
- Drugs which works by suppressing the appetite to have adverse effects such as the influence of psychotic, depressive and suicidal thoughts.
“People with excess body weight have an increased risk of heart disease and stroke risk. When added with drugs, it becomes more unreasonable,” said Dr. Wolfe.
It is hard to get weight loss drug that is really effective and have no side effects because weight gain could be caused by emotional, biological, social, psychological and environmental factors. So it is not possible that those many factors are treated by a capsule.
Besides that there are many pathways in the brain which are associated with appetite, making it difficult to create a drug that can suppress appetite if the factors involved in this instinct is not known.
“Nowadays eating too much has been equated with drug addiction. The point is that there is no magic to resolve the issue,” said Dr. Patricia Powell, aisten professor of clinical pharmacy at the University of South Carolina.
