Appetite suppressant

Appetite suppressants are a type of drug or supplement that are used to reduce hunger and, in turn, decrease food intake. They are often used as a tool for weight loss and obesity management.

Mechanism of Action

Appetite suppressants work by altering the body's hunger signals. They can affect the central nervous system, increasing the levels of certain neurotransmitters such as serotonin and norepinephrine, which can create a feeling of fullness and reduce the desire to eat. Some appetite suppressants also slow down the digestive process, which can help to prolong the feeling of fullness after eating.

Types of Appetite Suppressants

There are several types of appetite suppressants, including both prescription drugs and over-the-counter supplements. Prescription appetite suppressants, such as phentermine and orlistat, are typically used under the supervision of a healthcare provider. Over-the-counter appetite suppressants, such as green tea extract and conjugated linoleic acid, are more widely available but their effectiveness and safety are often less well-studied.

Risks and Side Effects

While appetite suppressants can be effective for weight loss, they also come with potential risks and side effects. These can include insomnia, high blood pressure, heart palpitations, and mood changes. Long-term use of appetite suppressants can also lead to nutrient deficiencies and eating disorders. It's important to consult with a healthcare provider before starting any new medication or supplement.
