Weight loss drugs or anti-obesity drugs are pharmacological agents which decrease or regulate weight. These drugs change one of the most fundamental processes of our body, weight regulation, in altering either eating or energy absorption of food. They affect the brain chemicals involved in both appetite and fat burning, thus affecting weight control. These drugs are usually prescribed by doctors and help people lose weight effectively.
There are many types of weight loss drugs available in the market. These include drugs for regulating appetite such as anticonvulsants, antidepressants, and phentermine; and drugs for decreasing appetite which includes drugs for controlling serotonin, norepinephrine, and dopamine levels such as phentermine, and hoodia gordonii. Some of these drugs also act as natural aphrodisiacs and are used to treat some sexual problems. These aphrodisiacs include Hoodia, which is a plantain from the Indian tropical belt. Another effective herb which decreases appetite is the hoodia gordonii. The hoodia gordonii plant is cultivated in Africa, South America, and it can also be found in Chinese herbal medicine.
Certain side effects of weight loss drugs are also noted. Some of these include tremors, agitation, depression, anxiety, restlessness, fever, headache, dry mouth, increased thirst, insomnia, irritability, chest pain, sweating, jaundice, and rapid heartbeat. Usually, when such symptoms occur, it is considered to be caused by the sudden drop of blood pressure (hypotension) in the body. In order to prevent such side effects, it is recommended that such individuals should maintain regular exercise. Regular exercise helps in maintaining normal blood pressure levels.
Individuals who are on medication for long periods must have regular check-ups with their health care providers. This is necessary to monitor the progress of medications, to make sure that they are still effective and working efficiently. People who are using such medications should avoid any forms of food that contain artificial sweeteners, as these may need to be reduced drastically. Individuals who are on medication should not drink beverages such as sodas and juices, as they may need to be reduced dramatically as well. Individuals on weight-loss drugs should talk to their health care provider about any concerns that they may have regarding their medication.
Dhurandhar says that weight loss drugs are often used for a short period of time to treat mild obesity. They are usually used to treat cases of obesity that are not severe enough to require medical treatment or that do not respond to lifestyle changes. However, some side effects of these medications can be serious and may need to be treated. For instance, one common side effect of these medications to treat obesity is that of constipation.
A decrease in appetite is often one of the side effects caused by many weight loss drugs. This is especially the case with some of these prescription drugs, as they often contain ingredients that suppress the appetite. If someone who is on a weight loss medication does not lose weight, they may need to reduce the dosage or even stop taking the medication.
