Appetite-suppressing weight reduction tablets help fill the stomach and reduce food cravings. They work by slowing down the brain’s appetite signal. Many are available over the counter. However, they can also be prescribed by your doctor.

Weight management medications should not be taken by people who are pregnant or breast-feeding. You should consult your health care provider before starting any prescription diet pill.

A number of natural ingredients are approved by the Food and Drug Administration (FDA) for use as appetite suppressants. One of the most commonly used is glucomannan. This dietary fiber is water-soluble and has been shown to be effective.

Another ingredient is guarana. The fruit contains high amounts of caffeine. Some studies have shown that guarana can be helpful for weight loss. But it can cause side effects such as anxiety, insomnia, and headaches.

There are many types of OTC diet pills available. Some of these are approved by the FDA for short-term use. Others are not. These supplements may interact with other drugs.

The Science Behind Appetite Suppressants: How they Work

Some over the counter pills are not safe for pregnant women or those with allergies. Those with diabetes or high blood pressure should speak with their physician before taking an appetite suppressant.

Prescription diet pills can also have more serious side effects. Taking a diet pill with other medications can increase your heart rate, cause nausea, or worsen depression. Also, a fetus can become harmed when a mother takes a medication during pregnancy.
