What are Phentermine Diet Pills for?
Phentermine is a drug used in common with a low-calorie diet, exercise, and a doctor-approved habit change program to help you lose weight. The drug is used in people who are overweight (obese) and have not been able to lose enough weight with diet and exercise alone. Losing weight and maintaining it can reduce many of the health risks that come with obesity, including heart disease, diabetes, high blood pressure, and shorter life spans.
It is not known how this drug helps people to lose weight. This drug may work by reducing your appetite, increasing the amount of energy used by your body, or by affecting certain parts of the brain. The drug is an appetite suppressant and belongs to a class of drugs called symptomatic amines.
How does phentermine diet pills work?
Phentermine belongs to a group of drugs called “anorectics,” also known as appetite suppressors.
Taking phentermine helps suppress your appetite, thereby limiting how many calories you eat. Over time, this can lead to weight loss.
While the exact mechanism behind the appetite reduction effects of phentermine remains unclear, the drug is thought to work by increasing levels of neurotransmitters in your brain.
Neurotransmitters are chemical messengers of your body and include norepinephrine, serotonin, and dopamine.
When the levels of these three chemicals increase, your hunger is reduced.
However, you can build a tolerance to the effects of phentermine that suppress appetite within a few weeks. In this case, you should not increase the dose of the drug, but stop using it altogether.

Like other stimulants, phentermine can increase energy levels and alertness. Stopping phentermine can cause fatigue, weakness and drowsiness as the brain learns to function without medication.
Fatigue is often severe in patients who take high doses of phentermine for a long time. Impaired cognitive function or “brain fog” is also common until withdrawal subsides. These effects are temporary and may be exacerbated by excessive stress and other external factors.
Phentermine suppresses appetite, which can lead to weight loss due to fewer calorie intake. Weight gain is common after stopping phentermine. While the exact cause is not understood, weight gain is thought to result in increased appetite and lack of exercise due to withdrawal symptoms such as fatigue.
The amount of weight gained after stopping phentermine varies depending on dosage, length of treatment and lifestyle factors such as diet and exercise.
