Phentermine is a prescription medication used as an appetite suppressant to aid in weight loss. It belongs to a class of drugs known as sympathomimetic amines, which stimulate the central nervous system. By increasing levels of neurotransmitters like norepinephrine, it helps reduce hunger and promotes a feeling of fullness. Phentermine is typically prescribed as part of a short-term plan, alongside dietary changes, exercise, and behavior modification.
Phentermine affects the hypothalamus in the brain, which controls hunger signals. It essentially "tricks" the brain into thinking the body is full, reducing food intake. This mechanism helps people who struggle with obesity or weight-related conditions such as high blood pressure, diabetes, or high cholesterol.
Phentermine is usually prescribed to individuals with a body mass index (BMI) of 30 or higher, or 27+ with obesity-related health conditions. It's not meant for cosmetic weight loss or casual dieting. Doctors will assess the patient’s health history, current medications, and weight loss goals before prescribing it.
While effective, Phentermine may cause side effects such as:
Increased heart rate
Dry mouth
Insomnia
Nervousness
Dizziness
Long-term use is not typically recommended due to potential for dependency or heart-related issues.
Phentermine should only be used under medical supervision. Avoid alcohol, other stimulants, and late-day dosing to reduce the risk of insomnia. Do not take it if you have a history of heart disease, hyperthyroidism, or uncontrolled high blood pressure.
Conclusion
Phentermine can be an effective short-term aid for weight loss when used properly. However, lifestyle changes remain essential for sustainable results. Always consult your doctor before beginning treatment.
