How does Semaglutide Work for Weight Loss? Unveil the Method

“How does Semaglutide work for weight loss?” you might wonder if you’re exploring ways to shed some pounds. Well, Semaglutide taps into your body’s own systems to help you feel less hungry and more satisfied with smaller portions. It specifically targets the GLP-1 receptors in your brain, crucial for controlling appetite. Imagine it as a friendly mimic of the incretin hormone that’s naturally made in your gut when you eat, tricking your body into feeling full sooner.

Consider it a supportive partner in your weight loss journey; Semaglutide, available as Wegovy and Ozempic, complements your efforts in healthy eating and staying active. Plus, it’s got a side gig of looking after your heart if you’re dealing with heart disease. So, it’s not just about dropping pounds but also about embracing a healthier, fuller life.

1. What Is Semaglutide?

Semaglutide falls into a category of medications called glucagon-like peptide-1 receptor agonists, or GLP-1 RAs. It works by imitating the GLP-1 hormone, which is naturally released in the gut after eating.

GLP-1 serves various functions, including stimulating the body to produce more insulin, which helps lower blood sugar levels. Consequently, semaglutide has been utilized by healthcare providers for over 15 years to manage Type 2 diabetes.

However, higher levels of GLP-1 also affect parts of the brain that regulate appetite and satiety signals. When combined with a healthy diet and exercise regimen, semaglutide can lead to significant weight loss, reducing the risk of conditions like cancer, diabetes, and heart disease in individuals who are obese or overweight.


2. How Does Semaglutide Work?

Semaglutide, classified as a glucagon-like peptide-1 receptor agonist, operates on weight loss by directly targeting GLP-1 receptors situated in the brain. Through this mechanism, it regulates appetite, diminishes hunger sensations, and enhances feelings of fullness. By mimicking the action of the natural hormone GLP-1, semaglutide aids in stabilizing blood sugar levels, reducing appetite, and facilitating weight loss. Additionally, it delays stomach emptying, prolonging the sensation of fullness, thus contributing to sustained weight loss when paired with a balanced diet and regular exercise. Administered via subcutaneous injections, semaglutide effectively aids weight loss, enabling some individuals to reduce 10% to 20% of their initial body weight.

3. The Role of Semaglutide in Weight Loss

Semaglutide, functioning as a glucagon-like peptide-1 (GLP-1) receptor agonist, interacts with the GLP-1 receptor in the brain responsible for appetite regulation.

It’s crucial not to combine semaglutide with other products containing semaglutide (such as Ozempic, Rybelsus) or other medications classified as GLP-1 receptor agonists.

GLP-1 aids weight loss through three primary mechanisms:

  1. It targets the brain centers involved in appetite regulation, particularly post-meal, potentially reducing overall food intake.
  2. It slows down stomach emptying, prolonging the sensation of fullness and satiety.
  3. Semaglutide therapy is typically recommended for long-term usage if it proves effective for the individual. Studies have demonstrated that with consistent use, semaglutide can facilitate weight loss and help individuals maintain it for over a year.

4. How Does Semaglutide Work for Weight Loss in Non Diabetics?

Various medications for obesity have emerged to curb appetite and promote weight loss, yet semaglutide stands out for its remarkable effectiveness.

In an initial study involving 2,000 obese adults, individuals utilizing semaglutide alongside a diet and exercise regimen were compared with those adopting the same lifestyle changes but without semaglutide. After 68 weeks, half of the participants on semaglutide shed 15% of their body weight, with nearly a third achieving a weight loss of 20%. Conversely, those solely relying on lifestyle modifications experienced a mere 2.4% weight reduction.

Subsequent studies have corroborated these findings, showcasing consistent results. However, it’s important to note that weight regain is common after discontinuing semaglutide.

Dr. Surampudi emphasizes that while dietary and exercise adjustments remain fundamental in managing obesity, the inclusion of anti-obesity medications such as semaglutide provides an additional strategy, tailored to individual clinical backgrounds.

5. Time Required for Semaglutide to Show Effects

The effects of semaglutide treatment may begin to manifest within the first four weeks, but the full impact typically requires several months to become apparent. Studies conducted over a span of 68 weeks have demonstrated significant weight loss outcomes, with adults shedding an average of about 35 lbs (15.9 kg).

Upon commencing treatment, your doctor will gradually increase your dosage to mitigate potential stomach-related side effects like nausea and diarrhea. It typically takes approximately 17 weeks to reach the final maintenance dose of semaglutide.

Research conducted by the manufacturer reveals that, on average, adults using semaglutide experienced a weight loss of around 35 lbs (15.9 kg) over 68 weeks, equating to roughly 15% of their initial body weight. In comparison, 31% of individuals receiving a placebo (inactive treatment) lost approximately 6 lbs (2.7 kg), or about 2.5% of their body weight.

In children aged 12 and older, semaglutide reduced BMI by 16.1% over 68 weeks, compared to a 0.6% reduction in the placebo group. Additionally, 77% of children receiving semaglutide experienced a BMI reduction of at least 5%, compared to only 20% in the placebo group.

6. Potential Side Effects of Using Semaglutide

The side effects associated with semaglutide use are generally mild, particularly when weighed against the potential complications of being overweight or obese.

Individuals utilizing semaglutide for weight loss may encounter:

  • Dizziness
  • Fatigue
  • Gastrointestinal problems like diarrhea, constipation, and bloating
  • Headaches
  • Stomach-related issues such as nausea, vomiting, or discomfort

Among individuals initiating semaglutide treatment, gastrointestinal issues are the most commonly reported. However, it’s possible to mitigate these side effects by starting with a lower dose and gradually increasing it over time.

7. Guidelines for Using Semaglutide

  • Semaglutide is administered via subcutaneous injection, and you’ll be instructed on how to prepare and administer it. Follow the directions on the prescription label carefully, taking it once weekly (every 7 days). Continue taking it unless advised otherwise by your healthcare team.
  • Dispose of used needles and pens in a designated sharps container rather than a regular trash can. If you don’t have a sharps container, contact your pharmacist or healthcare team to obtain one.
  • With each prescription and refill, you’ll receive a special MedGuide from the pharmacist. Make sure to read this information thoroughly each time.
  • Semaglutide comes with detailed instructions for use. Ask your pharmacist for guidance on administering the medication and read the provided information carefully. Don’t hesitate to reach out to your pharmacist or healthcare team if you have any questions.
  • Consult your healthcare team regarding the use of semaglutide in children, as special precautions may be necessary.
  • In case of overdosage, contact a poison control center or emergency room immediately if you believe you’ve taken too much of the medication.
  • Remember, semaglutide is intended for your use only. Do not share it with others.

These guidelines aim to ensure safe and effective use of semaglutide as prescribed by your healthcare provider.

8. Who Should and Shouldn’t Use Semaglutide

  • Have a body mass index (BMI) of 27kg/m2 or greater and at least one weight-related condition, such as high blood pressure, Type 2 diabetes, or high cholesterol.
  • Have a BMI of 30kg/m2 or greater.

However, you should avoid semaglutide if you have:

  • A history of medullary thyroid cancer.
  • A history of gallbladder disease.
  • A history of pancreatitis.
  • Multiple endocrine neoplasia syndrome type 2 (MEN2).

If you’re considering semaglutide for weight loss, your first step should be consulting your primary care physician (PCP). They are familiar with your personal and family medical history and can advise you on the best treatment for your condition. If you have diabetes and are already taking other medications, discuss acceptable and safe combinations of diabetes medications with your physician.
