How does phentermine medication work?
Phentermine is considered a suppressant, limiting how many calories you eat. Over time, this can lead to weight loss. It works by increasing the release of three neurotransmitters (Serotonin, Dopamine, and norepinephrine) in your brain which stimulate metabolism and suppress hunger. It also promotes the release of adrenaline and epinephrine hormones with fat burning properties accelerating weight loss. The expected average weight loss with phentermine is 5-10% of your initial body weight. Weight loss has translated to a significant decrease in waist circumference, improved insulin sensitivity (blood sugar control), as well as favorable effects on cholesterol levels.
