Semaglutide Weight Loss Treatment

At Centra Internal Medicine, we are committed to helping you achieve your weight loss goals through cutting-edge treatments. We are proud to offer exceptional weight loss solutions, including our Semaglutide Weight Loss Treatment 

Semaglutide is a potent GLP-1 receptor agonist that has garnered significant attention for its efficacy in helping individuals shed excess pounds and improve their overall health. 

Semaglutide is just one option available to our patients. We have also successfully treated countless patients with Mounjaro, Ozempic, and Wegovy.

We prescribe semaglutide (a type of GLP-1) because it has been FDA-approved for weight loss. Studies have shown it can help patients achieve long-term success when combined with a healthy diet plan. 

How do I know if I need help with weight management?

Each time you visit Centra Internal Medicine, a member of the team weighs you. If you’re over the healthy weight range for your age and height, Dr. Sahni can give you the guidance you need to keep your weight under control.


Your weight is categorized by your body mass index (BMI), a number calculated using your height and weight. The BMI classifications are:

  • Underweight: Under 18.5
  • Normal weight: 18.5 - 24.9
  • Overweight: 25.0 - 29.9
  • Obesity: 30.0 or above

It’s important to note that the current BMI system doesn’t differentiate between weight from muscle and fat. Some patients with high BMI are simply very muscular, but not obese. Because of this, only your doctor can determine if you need to lose weight.

It’s also perfectly healthy for your weight to fluctuate a bit. If you’re consistently gaining weight or losing weight and are having trouble stopping it, you could benefit from a weight management plan.

How can I manage my weight?

Most people recognize that eating a sufficient, healthy diet and getting exercise are important parts of controlling their weight. However, even if you feel like you’re doing everything correctly, you may need some help or motivation to truly change your habits.

As part of your personalized weight management plan, Dr. Sahni provides:

  • Specific healthy changes to your diet
  • Guidance for physical activity within your ability
  • Medications for weight loss when necessary
  • Reasonable goals for you to work toward


Your weight may be due to genetics, overeating, a lack of physical activity, stress, or a combination of several factors. While creating your plan, Dr. Sahni takes these into account to change your lifestyle in a way that works.

What happens if I don’t manage my weight?

Being outside of a healthy weight range can take a toll on your health if you don’t change your lifestyle. Obesity puts you at a higher risk for:

  • High blood pressure
  • Diabetes
  • High cholesterol
  • Heart problems
  • Sleep apnea
  • Stress on your bones and joints
  • Some cancers

Being overweight or obese can also decrease your mobility. Further, you get fatigued quickly, making it difficult to accomplish all of the things you’d like to get done in a day.

After assessing you and your health, Dr. Sahni gives you a list of specific ways that your weight is affecting your well-being.

If you’re struggling to lose weight, even if you feel like you’re doing everything right, call or book an appointment online at Centra Internal Medicine for guidance and motivation for weight management.
