What is Phentermine?
Phentermine is a stimulant-based prescription weight loss medication that has been used for decades to help people lose weight. It is a short-term appetite suppressant that works by affecting the central nervous system to reduce hunger. Unlike newer GLP-1 medications, Phentermine does not influence digestion or insulin but instead helps people consume fewer calories by directly suppressing their appetite.
How Does Phentermine Work?
Phentermine stimulates the release of norepinephrine, a hormone that triggers the body’s fight-or-flight response, increasing heart rate and reducing hunger signals. This leads to less food intake and enhanced calorie burning.
Who is Phentermine For?
- Adults with a BMI of 30 or higher
- Adults with a BMI of 27 or higher who have obesity-related conditions (diabetes, hypertension, etc.)
- Patients who need short-term assistance in controlling appetite and food intake
