Weight loss drugs or pharmacological agents are chemical compounds that either reduce or regulate weight. These drugs modify one of the most fundamental biological processes of the body, weight control, by regulating either food absorption or appetite, by manipulating either nutrient partitioning or metabolism. The Food and Drug Administration (FDA) approved many weight loss drugs over the years. Most of these medications have desirable effects on obesity, but many are considered controversial because of possible side effects and the ability to cause excessive weight loss. Several studies suggest that appetite suppression is a better alternative than some of these drugs. Most of these weight loss drugs can be purchased without a prescription.
The diet pill orlistat is a medication that is often prescribed for weight loss. This weight loss drug has been approved by the FDA for use in obese patients with heart disease, but it may cause serious side effects if taken without a doctor’s supervision. In order to be sure that your doctor will give you this medication, you should discuss its use with him or her and take time to do your research about this medication. Ask your doctor about potential side effects and how this medication may affect your medical conditions.
Metabolism or Lipid Peroxidation In the most extreme cases, the use of these weight loss drugs may lead to or worsen certain medical conditions. For example, Orlistat increases the cholesterol levels in the body and interferes with the normal functioning of estrogen at the cellular level. The estrogen levels become too high due to Orlistat’s ability to block the absorption of estrogen. When there is an excess amount of estrogen in the bloodstream, there is a greater risk of developing breast cancer, premenstrual syndrome, and polycystic ovarian syndrome (PCOS).
On the other hand, bupropion causes an increase in blood flow in the stomach, which could reduce stomach fat. However, evidence indicates that bupropion does not have much effect on reducing the amount of food that is eaten by people with obesity. In addition, studies indicate that when women taking bupropion diets are advised to restrict their caloric intake, they tend to reduce their diet significantly. As a result, they experience significant weight loss.
In addition, prescription weight loss drugs can lead to serious side effects. To begin with, Orlistat, Tagamet, and Bactrim are known to cause serious liver damage. People taking these drugs may develop pancreatitis, hepatitis, and cholestasis. And, individuals who suffer from obesity are particularly at risk for developing depression, diabetes, and high blood pressure.
New weight loss drugs approved by the FDA in 2021 include H2 blockers. These drugs act in a different way from the existing appetite suppressants. They prevent the body from producing the hormone insulin, which causes excess sugar to be stored in the fat cells. As a result, patients lose weight because their bodies no longer respond to hunger.
Another new medication available is called Xenical. It is similar to Xenical, an established dietary supplement, and is designed to be used in conjunction with meal replacement therapy. Xenical is available only with a doctor’s prescription because it has some of the same health risks associated with commonly used diet supplements. Another drug approved for weight loss is Fen-Phen. Like many of the diet supplements, it is not approved by the FDA for long-term use. And, it is not recommended to pregnant women or those with heart problems.
Although there are many new products on the market, some of the older, more well-known diet supplements remain popular. Glucophage (also known as lecithin) is one such supplement that has been approved by the FDA. It is a natural fatty acid that encourages the body to produce more glycogen, which is the glucose that supplies fuel to the muscles during exercise. Glucophage is available with a prescription but can also be purchased with a diet plan that includes regular exercise.
