Phentermine Weight Loss Programs - Denver, CO

What is Phentermine?

Oral phentermine Hydrochloride (HCL) is a prescription appetite suppressant, which has been successfully and safely used for weight loss for over 30 years. It is in the Sympathomimetic family of appetite suppressants (used for the short-term management of exogenous obesity.)

When used in conjunction with diet, exercise, and behavior therapy, phentermine may help you to lose weight more quickly.

How does phentermine work?

Phentermine works by stimulating the hypothalamus gland, (the region of the brain that controls the autonomic nervous system, regulating sleep cycles, body temperature, appetite, etc.) and affecting certain neurotransmitters to decrease the appetite.

Phentermine should NOT be used as a substitute for proper diet or exercise. For maximum effects, it must be used in conjunction with a well-balanced diet, exercise and can also be combined with Fit MD’s other weight loss programs.

Healthy modifications to your diet and activity levels must be developed and continued long-term in order to continue losing weight and/or prevent the lost weight from returning.

We look forward to helping you shed excess weight and become a better, healthier you!
