Understanding Wegovy Side Effects: What You Need to Know

Wegovy is a medication that contains the active ingredient semaglutide. Wegovy is approved for adults with obesity or those who are overweight with weight-related health conditions.

As with any medication, it is important to understand both the benefits and potential side effects. The most common side effects of Wegovy are gastrointestinal, and our providers at Centra Internal Medicine are here to support you through them. Many patients experience nausea, especially when starting Wegovy or increasing the dose. Other possible digestive symptoms include vomiting, diarrhea, constipation, and abdominal discomfort. Typically, these side effects are mild to moderate and tend to improve as your body gets used to the medication.

Additional side effects may include headache, fatigue, indigestion, burping, or bloating. Some patients notice mild injection site reactions, such as redness, itching, or swelling where the medication is administered.

While most side effects are manageable, Wegovy can occasionally cause more serious reactions. We encourage all patients to have an open conversation with their healthcare provider about any concerns or side effects they experience. If you notice severe, persistent, or worrisome symptoms, please contact our office promptly.

While Wegovy is an effective medication for weight loss, some patients may experience side effects, especially during the initial weeks of treatment or after a dosage increase. The most common side effects include nausea, vomiting, diarrhea, constipation, and abdominal discomfort.

Practical Tips from Centra Internal Medicine Providers:

• Eat Small, Frequent Meals: Our team recommends eating smaller, more frequent meals rather than large portions. This can help reduce nausea and ease digestion.

• Stay Hydrated: Sip water throughout the day to help prevent dehydration, particularly if you are experiencing vomiting or diarrhea. Increasing dietary fiber gradually and maintaining fluid intake can also help with constipation.

• Stay Consistent with Your Medication: Take Wegovy at the same time each week, exactly as prescribed by your provider. This helps maintain steady medication levels and may reduce side effects.

• Stay Upright After Meals: Avoid lying down immediately after eating, as this can intensify discomfort. Light activity, like a short walk, can promote digestion.

• When to Contact Centra Internal Medicine: If you experience severe or persistent side effects, such as ongoing vomiting, severe abdominal pain, or signs of dehydration, please contact Centra Internal Medicine right away. Our providers may adjust your dosage, pause dose escalation, or recommend additional medications to help control your symptoms.

Many patients who begin taking Wegovy (semaglutide) may experience side effects such as nausea, vomiting, diarrhea, constipation, or abdominal pain—especially when starting the medication or increasing the dose. These reactions are common and often improve as your body adjusts.

Our experienced providers can work with you to manage or reduce these side effects. Sometimes, adjusting the dose or slowing the rate at which the dose is increased allows your body more time to adapt, making symptoms less bothersome. However, not all side effects will resolve with dose changes alone, and some people may continue to experience discomfort even at lower doses.

If you are a Centra Internal Medicine patient and are experiencing side effects from Wegovy, please contact our office before making any changes to your medication. Our providers will assess your symptoms, discuss whether a dose adjustment is appropriate, and recommend strategies to help you feel better. We are here to support you every step of the way and ensure your treatment plan is safe and effective.

At Centra Internal Medicine, we understand that starting a new medication like Wegovy (semaglutide) for weight management can come with questions and concerns, especially about potential side effects. Our goal is to support you every step of the way, ensuring your treatment is both effective and comfortable.

Common Side Effects and Their Duration
Wegovy is known to cause gastrointestinal symptoms such as nausea, vomiting, diarrhea, constipation, and stomach pain. These side effects are most common when beginning the medication or when your dose increases. For most of our patients, these symptoms tend to be mild to moderate and typically improve within a few days to a few weeks, as your body adjusts. In some cases, side effects may persist for a longer period but often decrease in intensity and frequency over time.

When to Contact Your Centra Internal Medicine Provider
If you notice that your side effects are lasting for several weeks, worsening, or becoming hard to manage, please reach out to your provider. We may recommend adjusting your dosage or provide personalized strategies to help minimize your discomfort. In rare instances, ongoing or severe side effects may require stopping the medication. Additionally, any serious reactions—such as allergic responses or severe abdominal pain—should be treated as medical emergencies, and you should seek immediate care.
