Understanding Weight Loss Drugs
What Are Weight Loss Drugs?
Weight loss drugs are medications or supplements designed to assist in weight management. They can be prescribed by a doctor, purchased over the counter, or found in the form of herbal supplements. Their primary function is to help individuals reduce body weight, often by influencing appetite, metabolism, or fat absorption.
How Do They Work?
Weight loss drugs work through various mechanisms:
Appetite Suppression
Some drugs reduce hunger by affecting brain chemicals, making you feel fuller for longer.
Fat Absorption Inhibition
Others, like Orlistat, block the absorption of fat in the digestive system, reducing calorie intake.
Metabolic Rate Enhancement
Certain medications boost your metabolism, helping your body burn more calories at rest.
