Prescription Appetite Suppressants
Prescription appetite suppressants work by reducing feelings of hunger and increasing feelings of fullness, which can help to reduce overall food intake and promote weight loss. These medications are typically prescribed for individuals who have a body mass index (BMI) of 30 or higher, or for those with a BMI of 27 or higher with weight-related health conditions such as high blood pressure or diabetes.
There are several types of prescription appetite suppressants, including stimulants, serotonin and norepinephrine reuptake inhibitors (SNRIs), and gastrointestinal (GI) blockers.
Stimulant appetite suppressants, such as phentermine, work by increasing the release of neurotransmitters such as norepinephrine, which can reduce feelings of hunger and increase feelings of fullness.
SNRI appetite suppressants, such as lorcaserin, work by increasing levels of serotonin and norepinephrine in the brain, which can reduce appetite and promote feelings of fullness.
