Semaglutide
What is semaglutide?
Semaglutide is an active ingredient used in medicine and belongs to the group of GLP-1 receptor agonists. It is used in different medications and is particularly well known in connection with type 2 diabetes and medically supervised weight loss.
Many patients know semaglutide mainly through medications such as Wegovy, Ozempic, or Rybelsus. However, it is important to understand that semaglutide is the active ingredient, not the medication itself. Depending on the medication, the approved use, dosage form, dose, and treatment goal may differ.
In medically supervised weight loss, semaglutide may play a role when significant excess weight or obesity is present and lifestyle measures alone are not sufficient. Whether treatment is medically appropriate depends on several factors, including BMI, pre-existing conditions, current medication, possible contraindications, and the individual treatment goal.
At The Body Clinic, patients can have a medical suitability assessment for semaglutide to clarify whether medication-based weight loss may generally be an option.
What is semaglutide used for?
Depending on the medication, semaglutide is used in different medical areas. It is especially important to distinguish between semaglutide as an active ingredient for weight management and semaglutide as an active ingredient for type 2 diabetes.
- Weight management: Certain semaglutide medications may be used for medical weight loss when medically indicated.
- Type 2 diabetes: Other semaglutide medications are intended for the treatment of type 2 diabetes.
- Medical decision: Which medication is suitable depends on the diagnosis, treatment goal, risks, and individual medical suitability.
This distinction is important because not every semaglutide medication is automatically approved or appropriate for the same treatment. Use should therefore always be assessed and supervised by a physician.
Semaglutide in known medications
Semaglutide can be contained in different medications. The following examples show why the active ingredient, medication, and approved use should not be treated as the same thing.
| Medication | Active ingredient | Dosage form | Medical context |
|---|---|---|---|
| Wegovy | Semaglutide | Injection | Weight management when medically indicated |
| Ozempic | Semaglutide | Injection | Type 2 diabetes |
| Rybelsus | Semaglutide | Tablet | Type 2 diabetes |

How does semaglutide work in the body?
Semaglutide belongs to the group of GLP-1 receptor agonists. GLP-1 is a naturally occurring hormone in the body that is involved, among other things, in the regulation of hunger, satiety, blood sugar, and food intake.
As a GLP-1 receptor agonist, semaglutide is based on the action of this naturally occurring hormone. This allows the active ingredient to influence several processes that play a role in weight, eating behavior, and metabolism.
- Hunger and appetite: Semaglutide may help reduce hunger and appetite.
- Satiety: The feeling of fullness may be increased, so smaller meals may feel sufficient.
- Gastric emptying: Gastric emptying may slow down, which can help satiety last longer.
- Blood sugar regulation: The active ingredient can influence insulin-related metabolic processes in connection with food intake.
The effect is not the same for every person. Tolerability, comorbidities, dose, diet, physical activity, and treatment duration also influence how treatment progresses.
Semaglutide for weight loss
In medical weight loss, semaglutide should not be viewed in isolation. The active ingredient is always part of a physician-supervised treatment concept that should include nutrition, physical activity, behavior, health status, and follow-up monitoring.
Semaglutide may be medically relevant for people with obesity or significant excess weight when lifestyle measures alone are not sufficiently effective and additional health risks are present. These may include high blood pressure, prediabetes, type 2 diabetes, lipid metabolism disorders, or other weight-related conditions.
Important: Semaglutide does not replace a medical diagnosis, dietary changes, or follow-up monitoring. The active ingredient can support treatment, but it should not be used without medical assessment, obtained from unsafe sources, or taken according to a self-directed dosing schedule.
Semaglutide as an injection or tablet
Depending on the medication, semaglutide may be available as an injection or as a tablet. For patients, the key point is that the dosage form alone does not determine suitability. The approved use, treatment goal, and individual medical situation are more important.
| Form | Example | Classification | Important to know |
|---|---|---|---|
| Injection | Wegovy, Ozempic | Depending on the medication, weight management or type 2 diabetes | Use and dose must be determined by a physician |
| Tablet | Rybelsus | Type 2 diabetes | Not automatically an approved tablet option for weight loss |
Patients who are specifically looking for treatment with an injection can find further information about weight loss with injections and medical supervision. Patients interested in oral treatment options can also read more about weight loss tablets after medical assessment.
Who may be suitable for semaglutide?
Whether semaglutide is medically appropriate cannot be answered in general terms. The decision depends on several factors and should always be made individually by a physician.
An assessment may be particularly relevant if one or more of the following criteria apply:
- Obesity or significant excess weight
- Weight-related comorbidities
- Previous unsuccessful weight loss attempts despite dietary changes and physical activity
- Increased health risk due to weight
- A desire for physician-supervised treatment instead of using medication independently
At The Body Clinic, a specific active ingredient is not automatically recommended. Instead, physicians assess whether semaglutide, another active ingredient, or a non-medication-based concept is better suited to the patient’s starting point. Depending on the situation, a concept for weight loss without medication with an individual plan may also be more appropriate.
Can semaglutide be prescribed in Germany?
Medications containing semaglutide are prescription-only in Germany. This means that treatment requires a medical assessment. During this assessment, the physician clarifies whether there is a medical indication, whether possible risks or contraindications are present, and which medication fits the specific treatment goal.
Patients should not buy semaglutide without a prescription, obtain it from unsafe online sources, or use dosing recommendations from forums, social media, or patient reports. Especially with GLP-1 active ingredients, medical guidance, correct use, and regular follow-up monitoring are important.
At The Body Clinic, treatment therefore begins with a medical suitability assessment. During the medical consultation, it is discussed whether semaglutide for weight loss may be appropriate, whether another weight loss medication may be more suitable, or whether a different treatment approach should be considered first.
How much does treatment with semaglutide cost?
The cost of treatment with semaglutide depends on which medication is used, what type of medical supervision is needed, and how the individual treatment concept is structured. A general statement is therefore not meaningful without a medical assessment.
In many cases, medications for weight loss must be paid for privately. Whether health insurance coverage is possible depends on the individual case, the specific reason for treatment, and the respective insurance provider.
Patients can find information about the programs and general price orientation on the page prices for medical weight loss.
When is special caution important with semaglutide?
Semaglutide can cause side effects and is not suitable for everyone. Pre-existing conditions, current medication, possible contraindications, and previous intolerances should therefore be discussed carefully before starting treatment.
Frequently described side effects mainly affect the gastrointestinal tract. These can include nausea, vomiting, diarrhea, constipation, or abdominal pain. Which symptoms occur and how pronounced they are varies from person to person.
Special medical attention is important, among other things, in cases of:
- Existing gastrointestinal conditions
- Type 2 diabetes or other metabolic disorders
- Regular use of other medications
- Previous intolerance to GLP-1 medications
- Unclear symptoms before starting treatment
- Pregnancy, breastfeeding, or plans to become pregnant
Patients can find more information about the tolerability of individual semaglutide medications, for example, on our page about side effects of Wegovy with semaglutide.
Semaglutide, tirzepatide, and liraglutide compared
Semaglutide is not the only active ingredient that may play a role in medical weight loss. Tirzepatide and liraglutide are also often considered. These active ingredients differ in several ways, including active ingredient class, administration, approved use, and individual tolerability.
| Criterion | Semaglutide | Tirzepatide | Liraglutide |
|---|---|---|---|
| Active ingredient class | GLP-1 receptor agonist | GIP/GLP-1 receptor agonist | GLP-1 receptor agonist |
| Known medications | Wegovy, Ozempic, Rybelsus | Mounjaro | Saxenda |
| Administration | Injection or tablet, depending on the medication | Injection once weekly | Injection once daily |
| Key characteristic | GLP-1 active ingredient available in different dosage forms | Dual mechanism of action through GIP and GLP-1 | GLP-1 active ingredient with daily administration |
| To be assessed by a physician | Indication of the specific medication, current medication, risks, and treatment goal | BMI, comorbidities, tolerability, contraindications, and treatment goal | Suitability, daily administration, side effects, and long-term treatment strategy |
Patients who would like a broader comparison of the active ingredient groups can find an overview on the hub page active ingredients in weight loss medications. The detailed pages on tirzepatide as an active ingredient and liraglutide as an active ingredient can also help explain the differences.
Semaglutide at The Body Clinic
The Body Clinic supports patients with medical weight loss through an individual treatment concept. The focus is not on quickly using a specific active ingredient, but on determining which treatment option is medically appropriate, tolerable, and suitable for long-term medical support.
As part of the medical assessment, the physician discusses whether treatment with semaglutide may generally be suitable, whether another medication may be more appropriate, or whether a non-medication-based strategy may be better. Previous weight loss attempts, pre-existing conditions, current medication, possible side effects, and personal treatment goals are also taken into account.
If you would like to clarify whether semaglutide or another medical option may fit your situation, you can book a consultation for semaglutide and medical weight loss.
