Appetite suppressants are medications that help control food intake by altering the brain's hunger signals. These drugs work by increasing feelings of fullness or reducing appetite, making it easier for individuals to follow a calorie-restricted diet. Appetite suppressants can aid in short-term weight loss for individuals struggling with obesity, but they should be used alongside dietary changes and physical activity. Common appetite suppressants include medications such as phentermine and liraglutide, which may help people with obesity manage their weight more effectively. However, these medications come with potential side effects, and their use should always be monitored by a healthcare provider to ensure they are safe and effective for long-term use.
