Weight loss drugs or anti-obesity drugs are pharmacological agents which reduce or regulate weight normally. These drugs change one of our body’s most fundamental processes, weight control, by modifying either appetite metabolism or absorption of food in the intestines. They can also alter the balance between energy intake and energy expenditure. Weight loss drugs have gained much popularity in recent years because they seem to have the same efficacy as other weight loss programs, and many people have managed to lose weight without having to change their diet or exercise habits drastically.
Although there are numerous studies which show the efficiency of some weight loss drugs, they have also shown certain side effects in a few people. These side effects may be related to certain drug interactions, prolonged use, or even prolonged consumption of a particular drug in the long run. The most common side effect of the drug is that it may increase the heart rate, thereby increasing the blood pressure, and increasing the risk of blood clots. If this happens, stroke and heart attack will occur. However, in a study conducted by the National Institute on Drug Abuse, two out of six individuals who took agenda (a diet supplement) had a decreased risk for heart attacks, compared to those who did not take the supplement.
Apart from the above-mentioned side effects, there are also some precautions one should take before using some weight loss drugs. Before taking any medication, one should always consult a physician or dietician. This is very important especially if one is obese or suffering from diabetes. Some medications have been associated with these diseases. The physician or the dietician will discuss one’s medication with him and suggest the patient that medication he should take. In most cases, low-calorie diet supplements also help people lose weight.
Phentermine is one such drug that can help people reduce their hunger and increase the amount of food they eat. It has been proven to be effective in reducing the calorie intake and thus the amount of fat consumed by people. However, like orlistat, Phentermine also has some common side effects. One of them is that it can cause sleeplessness, which is very inconvenient for the user.
Another commonly used diet drug is Xenical. This is a drug that stimulates the central nervous system and causes a feeling of fullness. It also increases the metabolic rate, which results in rapid burning of fat. However, in spite of its beneficial results, some experts believe that there is not enough evidence to prove that drugs containing 20 percent of caffeine are effective in helping people to lose weight.
The best solution is to go for natural weight loss remedies, which involve a good diet, exercise and meditation. These are a combination of all the factors mentioned above, and can prove to be very effective. Apart from these natural methods, you can also look up alternate methods such as hydrotherapy and yoga. All these medications will help you lose the extra weight without any side effects.
