You’ve probably heard about Ozempic from multiple sources — both influencers and celebrities. This medication has become a hot topic across social media, TV shows, and interviews. Stars often share their weight loss secrets, and Ozempic frequently makes the list.

However, keep in mind the possibility of paid promotion. In show business, name-dropping certain drugs on stage or in media can be part of a well-orchestrated marketing strategy. Companies are willing to pay large sums for such mentions to create the impression that their product is the celebrity choice. This is part of modern reality, where the lines between real experience and advertising can blur.

When you hear such claims, it’s important to remember that every body is unique, and what works for one person may not work for another. Also, just because a medication is popular doesn’t mean it’s safe or effective for the general public. Always evaluate information critically and consult your doctor before considering these types of treatments.

What is Wegovy and how is it different from Ozempic?

Wegovy and Ozempic are brand names for the same active ingredient — semaglutide — but they differ in dosage and indication. Both are produced by Novo Nordisk, a pharmaceutical company based in Denmark.

  • Ozempic is approved for the treatment of type 2 diabetes. It helps control blood sugar levels and can also contribute to weight loss when used long-term (on average, around 12% of body weight over a year).
  • Wegovy is specifically intended for weight loss in people with overweight or obesity. It is prescribed in a higher dose than Ozempic to achieve greater weight reduction. But don’t forget: higher doses of any drug typically come with more side effects.

Ozempic started being used off-label for weight loss — even by people without type 2 diabetes — due to supply shortages of Wegovy. The manufacturer simply hasn’t been able to keep up with the skyrocketing demand.

How do these drugs work?

Medications like Wegovy and Ozempic mimic the action of a natural hormone called GLP-1 (glucagon-like peptide-1). This hormone plays a key role in appetite regulation, blood sugar control, and digestion. The main mechanisms include:

  • Appetite suppression: The drugs act on receptors in the hypothalamus, the brain’s hunger center. This helps reduce the desire to overeat.

  • Delayed gastric emptying: Slowing down the passage of food from the stomach to the intestines increases satiety, helping people eat less.

  • Blood sugar regulation: The medication stimulates insulin secretion after meals and reduces the liver’s glucose output, maintaining more stable blood sugar levels.

Who are these drugs for?

Ozempic is officially approved for type 2 diabetes. Wegovy, on the other hand, can be prescribed without diabetes, if the following criteria are met:

  • BMI ≥ 30, which qualifies as obesity;
  • BMI ≥ 27, if the person also has weight-related health conditions such as:
    • High blood pressure;
    • Type 2 diabetes;
    • Elevated cholesterol;
    • Cardiovascular disease.

Important! Prescribing Wegovy outside of these guidelines is not considered appropriate. Why? Because this drug (as well as Ozempic) has a number of potential side effects, some of which may cause lasting harm to your health.

Side Effects and Risks

Using Wegovy and Ozempic is associated with a number of side effects and potential health risks:

  • Gastrointestinal issues:

    • The most common side effects include nausea, vomiting, diarrhea, constipation, abdominal pain, and bloating.
    • These symptoms often appear during the first weeks of treatment and may decrease over time.

  • Risk of pancreatitis:

    • These medications may increase the risk of inflammation of the pancreas, especially in people with gallstones or high triglyceride levels.

  • Retinopathy:

    • In diabetic patients, retinopathy (damage to the retina) may develop or worsen, particularly during rapid blood sugar reduction.

  • Hormonal and tumor-related risks:

    • Animal studies have shown an increased risk of medullary thyroid carcinoma (MTC) with semaglutide. The drug is contraindicated in people with a family history of MTC or MEN 2 syndrome (multiple endocrine neoplasia type 2).

  • Muscle loss:

    • Rapid weight loss may lead to decreased muscle mass, especially without adequate physical activity and nutrition.

  • “Ozempic face”:

    • Includes loose or sagging skin due to fat loss under the skin. Rapid weight loss reduces elastin and collagen levels, which are important for skin firmness.
    • Possible symptoms:
      • More visible signs of aging, such as wrinkles;
      • Facial fat loss leading to sagging skin;
      • A hollow or gaunt appearance.

  • Risk of weight regain:

    • After stopping the medication, weight often returns if no long-term lifestyle changes are maintained.

  • Rare allergic reactions:

    • Allergic responses such as rash, itching, swelling, or breathing difficulties are possible and require immediate medical attention. This risk exists with any medication.

So why are these medications still widely used? Because both type 2 diabetes and obesity can seriously compromise health. When prescribing such treatments, doctors must always weigh the risk-benefit ratio. The benefits must clearly outweigh the potential risks.

However, these medications should never be used without prior medical evaluation and continuous health monitoring. They should only be prescribed for medically indicated reasons and not be considered a simple weight-loss solution in the absence of such indications.

SIBO Risk (Small Intestinal Bacterial Overgrowth) with Wegovy and Ozempic

The delayed gastric emptying caused by these medications may lead to food stagnation in the intestines. This creates an ideal environment for bacterial overgrowth in the small intestine — where such levels of bacteria are normally not present.

Why does this happen? Slowed gastrointestinal motility means that food stays longer in the small intestine. This prolonged retention promotes active fermentation of carbohydrates and nutrients by bacteria, resulting in excessive bacterial growth.

This microbial imbalance can not only cause local symptoms (bloating, pain) but also lead to systemic inflammation and nutrient malabsorption, particularly of vitamin B12 and iron.

Using Ozempic Solely for Weight Loss with Normal or Low Blood Sugar

Using Ozempic only for weight loss — without having elevated blood sugar — carries specific risks. The drug was designed for blood sugar control in people with type 2 diabetes. In individuals without this condition, it may lower blood sugar too much, increasing the risk of hypoglycemia.

Symptoms include: dizziness, weakness, shaking, sweating, mental confusion, and even fainting. These symptoms can also occur in people with diabetes, but in non-diabetics, they may be more pronounced because their bodies are less adapted to such drops in blood sugar.

Impact on Emotional Well-Being

Side effects such as chronic nausea, abdominal pain, and digestive disturbances not only affect physical health but also have a significant impact on mental well-being. The close connection between the brain and the gut means that digestive problems can trigger stress, anxiety, and even depression. Many patients experience social withdrawal, especially from events involving food or situations with limited access to restrooms. This vicious cycle between physical and emotional symptoms can significantly reduce quality of life and often requires additional psychological support.

The Problem of Weight Regain

One of the key challenges with Ozempic and Wegovy for weight loss is the high risk of rapid weight regain after stopping the medication. These drugs work by suppressing appetite and slowing gastric emptying, but once treatment ends, the body typically returns to its previous metabolic state. Appetite often increases, calorie intake rises, and the weight comes back.

This risk is especially high among individuals who do not make long-term lifestyle changes like healthier eating and regular exercise. In many cases, weight returns within a few months — and sometimes even exceeds the initial weight. This is due to metabolic adaptations and the absence of sustainable habits to support weight maintenance.

Moreover, excess weight rarely arises without underlying causes. It’s essential to identify and address root issues such as hormonal imbalances, chronic illnesses, or poor dietary patterns, rather than simply relying on weight-loss medication.

These concerns emphasize the need for a comprehensive approach to weight loss. Medication (only when truly needed) should always be combined with long-term lifestyle changes — including balanced nutrition, physical activity, and the resolution of underlying causes. This is the only way to achieve lasting results and avoid relapse.

Fake Medications

The U.S. Food and Drug Administration (FDA) has issued warnings about counterfeit versions of Ozempic in the American market. In December 2023, the FDA seized thousands of fake Ozempic 1 mg units from the legitimate pharmaceutical supply chain. Laboratory tests found unidentified ingredients and non-sterile needles, which increase the risk of infections.

Counterfeit drugs may contain incorrect or missing active substances and harmful contaminants, making them extremely dangerous. In June 2024, the World Health Organization (WHO) issued a global alert about falsified batches of Ozempic discovered in the U.S., U.K., and Brazil. As of now, no fake Ozempic has been reported in Canada.

Conclusion

Ozempic and Wegovy have become widely discussed due to their proven effectiveness in treating type 2 diabetes and promoting weight loss. However, their popularity should not overshadow the fact that they require strict medical supervision. Using these medications without proper indications, without considering individual health status, or without lifestyle adjustments can reduce their benefits and lead to serious side effects.

Weight loss is a complex task. It requires attention not only to pharmaceuticals but also to diet, exercise, and root causes of weight gain. These drugs can be helpful tools — but only as part of a broader treatment plan developed and monitored by a healthcare provider. Popularity must never replace a conscious, informed approach to health.

Before starting Ozempic or Wegovy, always consult your doctor, undergo appropriate evaluation, and discuss all potential risks and alternatives. That’s the only way to achieve sustainable results and avoid unwanted consequences.
