Wegovy, which contains the active ingredient Semaglutide, is a self-injectable medication intended for the treatment of obesity or overweight with associated risk factors. The drug works by mimicking a natural hormone in the body called GLP-1, which plays a key role in regulating appetite and food intake. It helps reduce feelings of hunger, increases feelings of fullness, and slows down gastric emptying, ultimately leading to weight loss.
Obesity is an increasingly prevalent health issue in Israel and worldwide. According to data from the Ministry of Health, about 50% of the adult population in Israel suffers from overweight, and about 20% of them are classified as suffering from obesity. This data highlights the need for effective and safe weight management solutions, with Wegovy offering an innovative and clinically proven treatment option. The drug has been approved for use by the U.S. Food and Drug Administration (FDA) and other regulatory bodies worldwide, and is now also available in Israel.
This guide will answer the central question “What is Wegovy?” and delve into its mechanism of action, review frequently asked questions, present a practical usage guide, compare it to other medications, review relevant clinical findings, detail the safety profile and side effects, debunk common myths, and provide an Israeli perspective on the drug, all with the aim of providing a comprehensive and clear understanding.

The Science: How Wegovy Works for Weight Loss
Wegovy is a GLP-1 receptor agonist. GLP-1 is a natural hormone secreted in the intestines in response to eating. Its main role is to stimulate insulin secretion from the pancreas when blood sugar levels are high and to suppress glucagon secretion (a hormone that raises blood sugar levels). Additionally, GLP-1 acts on satiety centers in the brain, reducing feelings of hunger and increasing feelings of fullness after meals.
The active ingredient in Wegovy, Semaglutide, mimics the action of natural GLP-1 in the body but with a significant advantage: it is more resistant to breakdown by enzymes in the body, allowing it to remain active for a longer period, which enables only one injection per week. Its prolonged action leads to several key effects that contribute to weight loss: significant appetite suppression, slowing gastric emptying (which provides a longer-lasting feeling of fullness), and improved control of blood sugar levels.
The combination of reduced hunger, increased fullness, and slowed digestion leads to naturally and consistently reduced calorie intake. In this way, Wegovy helps individuals suffering from overweight or obesity achieve significant and healthy weight loss, with its unique mechanism of action offering a multi-system approach to addressing this complex issue.
Frequently Asked Questions about Wegovy
What is Wegovy and how is it different from other weight loss medications?
Wegovy is a weekly injectable medication that contains Semaglutide, a GLP-1 receptor agonist. It differs from other medications in that it mimics a natural hormone in the body for appetite regulation, offers the convenience of weekly use, and has been clinically proven to be particularly effective in achieving significant and long-term weight loss.
Who is Wegovy intended for?
Wegovy is intended for adults suffering from obesity (BMI of 30 kg/m² and above) or overweight (BMI of 27 kg/m² and above) with at least one weight-related comorbidity, such as hypertension, type 2 diabetes, or dyslipidemia. Its use should be in conjunction with a reduced-calorie diet and exercise program.
How is Wegovy used?
Wegovy is administered via a self-injection subcutaneously once a week, on a fixed day, at any time of day, with or without food. The initial dose is low and gradually increases (titration) over several weeks to minimize side effects until reaching the full maintenance dose.
Does Wegovy require a doctor’s prescription?
Yes, Wegovy is a prescription medication. It is necessary to consult with a doctor or endocrinologist to assess your suitability for treatment, obtain a prescription, and monitor the treatment regularly. The doctor will determine the appropriate dosage and the rate of dosage increase.
What are the common side effects of Wegovy?
The most common side effects are gastrointestinal and include nausea, vomiting, diarrhea, constipation, and abdominal pain. They are usually mild and tend to resolve over time, especially as the body adjusts to the dosage. Adhering to a gradual dosage increase and staying well-hydrated can help reduce them.
In-Depth Guide to Success with Wegovy
Step 1: Comprehensive Medical Evaluation
Before starting treatment with Wegovy, a thorough medical evaluation must be conducted by a family physician, endocrinologist, or a doctor specializing in obesity. The doctor will review your medical history, perform relevant blood tests, and assess your Body Mass Index (BMI) to ensure you meet the criteria for treatment. Additionally, they will discuss your expectations from the treatment and potential risks.
Step 2: Initiating Treatment with a Low Dose and Titration
Treatment with Wegovy begins at a low dose (0.25 mg) and is gradually increased (titration) once a week, typically every four weeks, until reaching the full maintenance dose (2.4 mg). This gradual increase is critical to minimize gastrointestinal side effects and allow the body to adjust to the medication. It is important to adhere to the titration schedule as determined by your doctor.
Step 3: Proper Injection and Treatment Routine
Wegovy comes in a pre-filled pen injector. The medication should be injected subcutaneously (Subcutaneous injection) once a week, on a fixed day, at any time of day, with or without food. The injection can be administered in the abdomen, thigh, or upper arm. It is important to rotate the injection site weekly. Carefully read the detailed instructions in the patient leaflet and consult with your doctor or nurse regarding the correct injection technique.
Step 4: Lifestyle Changes and Medical Monitoring
Wegovy is most effective when combined with a comprehensive lifestyle change program, including a reduced-calorie diet and regular physical activity. It is important to maintain regular medical follow-up with your treating physician to assess treatment efficacy, manage side effects, and monitor progress. The doctor can adjust the treatment plan according to your individual needs.
Comparison of Alternatives for Wegovy
Wegovy is not the only medication that acts on the GLP-1 mechanism and is intended for weight loss. There are several other alternatives on the market, such as Ozempic, Saxenda, and Rybelsus. Although they all use similar active ingredients (semaglutide or liraglutide), they differ in characteristics such as route of administration, treatment frequency, dosages, and from an Israeli perspective, also in insurance coverage and availability.
The differences between the medications are significant and can influence the choice of the appropriate treatment. For example, while both Wegovy and Ozempic contain semaglutide and are administered once a week, Ozempic is primarily approved for the treatment of type 2 diabetes with the added benefit of weight loss, whereas Wegovy is specifically approved for obesity. Saxenda, on the other hand, contains liraglutide and requires daily injections, while Rybelsus is semaglutide in a daily oral tablet form.
The following table presents a detailed comparison of the different medications, addressing key characteristics, and how each may fit a different patient profile. It is important to remember that the choice of medication should always be made in consultation with a physician, who will consider the overall health condition, patient preferences, and insurance coverage.

Myths vs. Reality about Wegovy
Myth: Wegovy is a “magic pill” that solves weight issues effortlessly.
Reality: Wegovy is a powerful tool for weight loss, but it is not a magic solution. Its maximum effectiveness is achieved in conjunction with lifestyle changes, including a reduced-calorie diet and regular physical activity. The medication helps facilitate the weight loss process by reducing appetite and increasing satiety, but the patient still needs to make conscious and healthy choices.
Myth: Anyone using Wegovy will experience severe nausea and be unable to function.
Reality: Nausea is indeed a common side effect, especially at the beginning of treatment, but it is usually mild and subsides over time. The titration protocol (gradual dose increase) is designed specifically to minimize these effects and allow the body to adjust. Most patients adapt well to the medication, and nausea can be managed through dietary strategies and minor adjustments.
Myth: Once you stop taking Wegovy, all the weight comes back immediately.
Reality: Like any obesity treatment, stopping the medication without maintaining a healthy lifestyle can lead to weight regain. However, Wegovy helps patients adopt healthier eating habits and change their relationship with food. Maintaining these habits after stopping treatment, and if necessary transitioning to another maintenance treatment or a lower dose, can help sustain the weight loss achieved.
