How Do Weight Loss Medications Work?



Weight loss medications can be a useful tool for people struggling to lose weight, particularly when combined with a healthy diet and regular physical activity. There are several different types of weight loss medications available, each of which works in a slightly different way. Here is an overview of how some common weight loss medications work:

Phentermine

Phentermine is a stimulant that works by decreasing appetite and increasing feelings of fullness. It is often used as part of a weight loss plan that includes a reduced calorie diet and regular physical activity. Phentermine is typically prescribed for short-term use, as it can be habit-forming and may have side effects such as increased heart rate and blood pressure.

Orlistat

Orlistat is a medication that works by inhibiting the absorption of fat in the intestine. It is taken as a pill and is typically prescribed for people who are obese or have a high body mass index (BMI). Orlistat can cause side effects such as diarrhea, flatulence, and abdominal pain, and it is important to follow a low-fat diet while taking the medication to minimize these effects.

Liraglutide

Liraglutide is a medication that works by mimicking the effects of a hormone called GLP-1, which helps regulate appetite and food intake. It is typically prescribed for people who are obese or have a high BMI, and it is usually taken as a daily injection. Liraglutide can cause side effects such as nausea, vomiting, and diarrhea, and it is important to follow a reduced calorie diet while taking the medication.

Bupropion/naltrexone

Bupropion and naltrexone are medications that are sometimes used in combination to help with weight loss. Bupropion is an antidepressant that may also help with weight loss by decreasing appetite and increasing energy expenditure. Naltrexone is a medication that is typically used to treat substance abuse disorders, but it may also help with weight loss by decreasing appetite and increasing feelings of fullness. Bupropion/naltrexone can cause side effects such as dizziness, dry mouth, and constipation, and it is important to follow a reduced calorie diet while taking the medication.

It's important to note that weight loss medications should not be used as a standalone solution for weight loss. Instead, they should be used as part of a comprehensive weight loss plan that includes a healthy diet and regular physical activity. It's also important to discuss the potential risks and benefits of weight loss medications with a healthcare professional, such as a doctor or pharmacist, before starting a medication. In Tampa, there are many healthcare professionals who can help you determine if a weight loss medication is right for you and assist you with developing a comprehensive weight loss plan.
