What are Prescription Weight Loss Medications?
Prescription weight loss medications are drugs that are approved by the FDA to help individuals with obesity or overweight lose weight.

What are prescription weight loss medications?
Prescription weight loss medications are medications that are specifically designed to aid in weight loss and are only available with a doctor’s prescription. These medications work in various ways, such as suppressing appetite, increasing feelings of fullness, or altering the body’s metabolism. They are typically recommended for individuals who are obese or overweight and have not seen significant weight loss results through diet and exercise alone.
Prescription weight loss medications are often used in conjunction with a healthy diet and regular exercise, as they can help enhance the effectiveness of these lifestyle changes. However, it’s essential to note that these medications are not a magic bullet and should not be relied upon as the sole solution for weight loss. Instead, they should be used as part of a comprehensive weight loss plan that includes behavior modification, healthy eating, and regular physical activity.
How do prescription weight loss medications work?
Prescription weight loss medications work in different ways, depending on the specific medication. Some medications, such as phentermine, work by suppressing appetite, making it easier to stick to a reduced-calorie diet. Other medications, such as orlistat, work by blocking the absorption of fat in the digestive tract, reducing the number of calories absorbed from fat-containing foods. Additionally, some medications, such as liraglutide, work by increasing feelings of fullness and satisfaction, reducing hunger and cravings.
Regardless of how they work, prescription weight loss medications are designed to aid in weight loss by making it easier to stick to a healthy diet and exercise plan. By reducing hunger, increasing feelings of fullness, or altering the body’s metabolism, these medications can help individuals achieve and maintain significant weight loss over time. However, it’s essential to remember that these medications are not a substitute for a healthy lifestyle, and should only be used under the guidance of a healthcare professional.
Who is eligible for prescription weight loss medications?
Prescription weight loss medications are typically recommended for individuals with a body mass index (BMI) of 30 or higher, which is considered obese. In some cases, individuals with a BMI of 27 or higher who have certain health conditions, such as high blood pressure or type 2 diabetes, may also be eligible for these medications. Additionally, individuals who have tried other weight loss methods, such as diet and exercise, and have not seen significant results may be considered for prescription weight loss medications.
It’s essential to note that prescription weight loss medications are not suitable for everyone, and should only be used under the guidance of a healthcare professional. Individuals with certain health conditions, such as high blood pressure, heart disease, or a history of stroke, may not be eligible for these medications.

In rare cases, more serious side effects, such as increased heart rate, blood pressure, or psychiatric disorders, can occur. It’s essential to carefully review the potential side effects of any medication with your healthcare professional before starting treatment.
In addition to physical side effects, prescription weight loss medications can also have psychological and emotional impacts.
