Losing weight can be tough, but there’s a medicine called semaglutide that’s getting a lot of attention for helping people drop pounds. Originally, doctors used it to help people with type 2 diabetes control their blood sugar. But they noticed that it also made people lose weight. So now, it’s used for both purposes. Semaglutide goes by a few different names, like Ozempic, Rybelsus, and Wegovy, with Wegovy being the one doctors prescribe specifically for losing weight.

What’s cool about semaglutide is that it works with your body to make you feel less hungry. It does this by acting on a part of your brain that controls your appetite. When you’re not as hungry, you eat less, and over time, this can lead to weight loss. Plus, it has other benefits, like helping your body handle sugar better, which is great for your overall health.

People who’ve used semaglutide for weight loss have seen some pretty impressive results, with many losing a significant amount of their body weight. It’s given as a shot once a week, and while it has some side effects like stomach upset or headaches, most people find they go away after a while.

What is semaglutide?

Semaglutide is a medication that belongs to a class of drugs known as glucagon-like peptide-1 (GLP-1) receptor agonists. It mimics the action of the GLP-1 hormone, which is naturally produced in the body. This hormone is released after eating and helps regulate blood sugar levels by stimulating the pancreas to release insulin when blood sugar levels are high. Additionally, GLP-1 slows down gastric emptying, which helps you feel fuller for longer periods, and reduces the amount of sugar the liver makes.

Semaglutide is used in the treatment of type 2 diabetes to improve blood sugar control in adults, alongside diet and exercise. It’s also used for weight management in adults who are obese or overweight and have at least one weight-related condition, such as high blood pressure, type 2 diabetes, or high cholesterol.

The medication is available under various brand names, including Ozempic for diabetes management and Wegovy for weight loss. It is administered through subcutaneous injections, which means it’s injected under the skin, typically once a week. Semaglutide has been shown to be effective in reducing blood sugar levels in people with type 2 diabetes and in helping people lose weight when used alongside a reduced-calorie diet and increased physical activity.

How Effective is Semaglutide for Weight Loss?

Semaglutide has proven to be highly effective for weight loss, particularly in individuals who are obese or overweight with at least one weight-related condition such as high blood pressure, type 2 diabetes, or high cholesterol. Clinical trials and studies have demonstrated significant weight loss in participants using semaglutide as part of a comprehensive weight management program that includes diet and exercise.

One of the landmark studies published in the New England Journal of Medicine in 2021 showed that participants who took semaglutide (marketed as Wegovy for weight loss) lost, on average, 14.9% of their initial body weight over 68 weeks. This is a substantial reduction compared to those who were on a placebo, who lost just 2.4% of their initial body weight.

The effectiveness of semaglutide for weight loss is attributed to its action on the GLP-1 receptors in the brain, which helps regulate appetite and food intake. By mimicking the GLP-1 hormone, semaglutide increases insulin secretion, decreases glucagon secretion, and slows gastric emptying, leading to a decrease in appetite and caloric intake, which ultimately results in weight loss.

How It Works

Semaglutide works by mimicking the actions of a hormone in your body known as glucagon-like peptide-1 (GLP-1). This hormone plays a crucial role in managing your appetite and how your body handles blood sugar. Here’s a breakdown of how semaglutide works to help with weight loss and blood sugar control:

  1. Appetite Regulation: GLP-1 is released from your intestines after you eat, sending signals to your brain that make you feel full or satisfied. Semaglutide acts on these GLP-1 receptors in the brain, enhancing this feeling of fullness, which can lead to eating less and, over time, weight loss.
  2. Insulin Release: When blood sugar levels rise, GLP-1 stimulates the pancreas to release insulin, a hormone that helps lower blood sugar by allowing it to be used as energy or stored. Semaglutide enhances this process, improving blood sugar control in people with type 2 diabetes.
  3. Slows Gastric Emptying: Semaglutide slows down the rate at which your stomach empties its contents into the small intestine. This slower gastric emptying helps control blood sugar spikes after meals and prolongs the feeling of fullness, further contributing to reduced calorie intake and weight loss.
  4. Reduces Liver Sugar Production: By mimicking GLP-1, semaglutide can also help reduce the amount of sugar your liver makes, which is especially important overnight and between meals to prevent blood sugar levels from getting too high.

Dosage and Administration

The dosage and administration of semaglutide can vary depending on its intended use, whether for the treatment of type 2 diabetes or for weight management. It’s important to follow your healthcare provider’s instructions closely when using semaglutide. Here’s a general overview:

For type 2 diabetes (as Ozempic):

  • Starting Dose: The typical starting dose for Ozempic is 0.25 mg once a week for the first 4 weeks. This dose is intended for your body to get used to the medication and is not effective for blood sugar control.
  • Maintenance Dose: After the first 4 weeks, the dose is increased to 0.5 mg once a week. Depending on your body’s response and blood sugar levels, your doctor may further increase the dose to 1 mg once a week, and, in some cases, up to 2 mg once a week.

For weight management (as Wegovy):

  • Starting Dose: Wegovy is started at a dose of 0.25 mg once a week for the first 4 weeks.
  • Dose Escalation: The dose is then increased every 4 weeks through a stepwise program: 0.5 mg for weeks 5-8, 1 mg for weeks 9–12, 1.7 mg for weeks 13–16, and finally, 2.4 mg once a week from week 17 onwards as the maintenance dose.


  • Semaglutide is administered as a subcutaneous injection, which means it’s injected under the skin. Common sites for the injection include the abdomen, thigh, or upper arm. It’s important to rotate the injection sites to avoid skin problems.
  • The injections are typically given once a week, on the same day each week, and can be administered at any time of the day, with or without meals.
  • It comes in a pre-filled, disposable, single-use pen that’s designed for easy use. Your healthcare provider will show you how to use the injection pen correctly.

What Dosage Should One Consume for Weight Loss?

For weight management, the typical dosage starts at 0.25 mg once a week for four weeks, gradually increasing to a maintenance dose of 2.4 mg once a week. Dosage adjustments are based on individual response and tolerability.

How Semaglutide is Injected?

Semaglutide for Weight Loss

Semaglutide is administered as a subcutaneous injection, meaning it’s injected into the fatty layer just beneath the skin. This method allows the medication to be absorbed slowly into the bloodstream. Here’s a step-by-step guide on how semaglutide is typically injected, whether you’re using it for type 2 diabetes management (as Ozempic) or for weight loss (as Wegovy):


  1. Gather Supplies: Ensure you have the semaglutide injection pen, a new needle (compatible with your pen), alcohol wipes, and a sharps disposal container.
  2. Check the medication: Verify the medication name and concentration, ensure it’s not expired, and check for any particulate matter or discoloration.
  3. Wash Hands: Wash your hands thoroughly with soap and water.

Attaching the needle:

  1. Remove the Pen Cap: Take off the cap of the semaglutide pen.
  2. Attach the Needle: Take a new needle, remove the protective seal, and attach it to the pen by screwing it on until it’s tight. Then, remove the outer needle cap and keep it for later. Remove the inner needle cap and dispose of it.

Priming the Pen (If Required):

  1. Prime the Pen: Some pens require priming before the first use or if the pen has not been used for a while. Priming means expelling air from the pen to ensure the correct dose can be delivered. Follow the specific instructions for your pen model, which usually involve selecting a dose and pressing the button until a drop of medication appears at the needle tip.

Selecting the Dose:

  1. Set the dose: Dial the correct dose as prescribed by your healthcare provider.

Choosing and Preparing the Injection Site:

  1. Select the site: Common injection sites include the abdomen (at least 2 inches away from the belly button), the thigh, or the upper arm. Rotate the sites with each injection to avoid tissue damage or irritation.
  2. Clean the Site: Use an alcohol wipe to clean the skin where you’ll inject. Let the area dry.

Injecting the Medication:

  1. Inject the Dose: Insert the needle into the cleaned skin at a 90-degree angle (straight in). Press the dose button until the pen’s dose counter returns to zero. Hold the button and keep the needle in place for 6–10 seconds to ensure the full dose is delivered.
  2. Remove the needle: pull the needle out of the skin and place the outer needle cap back onto the needle. Unscrew the needle and dispose of it safely in a sharps disposal container.

After the injection:

  1. Recap the Pen: Put the cap back on the pen and store it as directed. Store it in a refrigerator or at room temperature, away from direct light and heat.
  2. Wash Hands: Wash your hands again.
