Wegovy, a prescription medication with the active ingredient semaglutide, is used for weight loss and managing heart risks in certain adults and teens. While effective, it can cause serious side effects that require attention.
Understanding what are serious side effects of Wegovy helps users stay safe. This article explains these risks in simple, clear language.
Understanding Wegovy and Its Purpose
Wegovy is a GLP-1 receptor agonist given as a weekly injection. It mimics a hormone that controls appetite and blood sugar, aiding weight loss.
It’s approved for adults with obesity or overweight with health issues, and teens aged 12 and older with obesity. The drug works best with a low-calorie diet and exercise.
Most users tolerate Wegovy well, but it can cause side effects, some of which are serious. Knowing these risks helps you monitor your health. Always discuss concerns with your doctor before starting treatment. Regular check-ins ensure safe use.
Common Side Effects vs. Serious Side Effects
Wegovy commonly causes mild side effects like nausea, diarrhea, and headache. These often improve as your body adjusts to the medication. Serious side effects, however, are rare but can be life-threatening. Understanding what are serious side effects of Wegovy is crucial for safe use.
Serious side effects require immediate medical attention. They can affect organs like the pancreas, kidneys, or thyroid. Being aware of these risks helps you act quickly if symptoms appear. Always report unusual symptoms to your healthcare provider.
Serious Side Effects of Wegovy
Wegovy’s serious side effects, though uncommon, can have significant health impacts. These are listed in the drug’s FDA prescribing information. Recognizing these risks helps you stay proactive about your health. Below are the main serious side effects to watch for:
- Pancreatitis
- Gallbladder problems
- Kidney issues
- Thyroid tumors (boxed warning)
- Severe low blood sugar (in people with diabetes)
- Allergic reactions
If you experience symptoms like severe pain or swelling, seek medical help right away. Early action can prevent complications. Your doctor can guide you on managing these risks.
Pancreatitis
Pancreatitis, or inflammation of the pancreas, is a rare but serious side effect. Symptoms include severe abdominal pain, nausea, vomiting, and fever. This condition can be life-threatening if untreated. Heavy alcohol use may increase the risk.
Stop taking Wegovy and contact your doctor if you notice these symptoms. They may order tests to confirm pancreatitis. Avoiding alcohol and fatty foods can help reduce this risk.
Gallbladder Problems
Wegovy can increase the risk of gallbladder issues, such as gallstones or cholecystitis (gallbladder inflammation). Symptoms include upper abdominal pain, fever, and yellowing of the skin or eyes (jaundice). These issues are more common in those losing weight rapidly.
Gallbladder problems may require surgery in severe cases. Report symptoms to your doctor immediately. A low-fat diet may help lower this risk during treatment.
Kidney Issues
Kidney problems, including acute kidney injury, are rare but serious. They can occur due to dehydration from side effects like vomiting or diarrhea. Symptoms include reduced urine output, swelling in the legs, and fatigue. Staying hydrated is critical to preventing kidney issues.
If you notice these signs, seek medical care right away. Your doctor may adjust your dose or monitor kidney function. Drinking plenty of water supports kidney health.
Thyroid Tumors (Boxed Warning)
Wegovy carries a boxed warning for the risk of thyroid C-cell tumors, including medullary thyroid carcinoma (MTC). This risk comes from animal studies, and it’s unclear if it applies to humans. Symptoms include neck swelling, trouble swallowing, or hoarseness. Those with a history of MTC or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2) should avoid Wegovy.
Report any neck-related symptoms to your doctor immediately. Regular monitoring can help catch issues early. Discuss your family medical history before starting treatment.
Severe Low Blood Sugar
In people with type 2 diabetes, Wegovy can cause severe low blood sugar (hypoglycemia), especially if combined with other diabetes medications. Symptoms include shakiness, sweating, confusion, and fainting. This risk is higher when doses are increased.
Monitor blood sugar levels closely if you have diabetes. Your doctor may adjust your diabetes medications. Always carry a quick sugar source, like glucose tablets, in case of emergencies.
Allergic Reactions
Serious allergic reactions to Wegovy are rare but possible. Symptoms include rash, itching, swelling (especially of the face or throat), and trouble breathing. These reactions can be life-threatening if not treated promptly.
If you experience signs of an allergic reaction, stop Wegovy and seek emergency care. Your doctor may switch you to a different medication. Always report allergies before starting treatment.
Who Is at Higher Risk?
Certain groups face a higher risk of serious side effects. People with a history of pancreatitis, gallbladder disease, or kidney problems need extra caution. Those with type 2 diabetes are more prone to low blood sugar. A family history of thyroid cancer or MEN 2 increases thyroid tumor risk.
Pregnant women or those planning pregnancy should avoid Wegovy due to potential fetal harm. Teens on Wegovy may experience gallbladder issues or rashes more often than adults. Discuss your medical history with your doctor to assess risks.
Managing and Monitoring Side Effects
Monitoring for serious side effects is essential while taking Wegovy. Keep a symptom diary to track any unusual changes, like severe pain or swelling. Regular check-ups with your doctor help catch issues early. Blood tests may be needed to monitor kidney or pancreas function.
Stay hydrated to reduce the risk of kidney problems. Avoid heavy alcohol use, as it can worsen pancreatitis risk. Report any concerning symptoms to your healthcare provider immediately.

Lifestyle Tips to Reduce Risks
A healthy lifestyle can minimize the risk of serious side effects. Follow a low-fat, balanced diet to support gallbladder health. Stay hydrated, especially if you experience vomiting or diarrhea. Regular exercise enhances Wegovy’s weight loss benefits.
Avoid excessive alcohol, as it can increase pancreatitis and dehydration risks. Monitor blood sugar if you have diabetes. Discuss all medications and supplements with your doctor to avoid interactions.

Before starting Wegovy, share your full medical history with your doctor. Mention any past issues with your pancreas, kidneys, or thyroid. Discuss current medications, especially for diabetes or heart conditions. This helps your doctor assess your risk for serious side effects.
During treatment, report side effects promptly. Your doctor may adjust your dose or order tests to monitor your health. Regular follow-ups ensure Wegovy remains safe and effective for you.
Special Considerations for Certain Groups
People with type 2 diabetes need to monitor for low blood sugar, especially when starting or increasing doses. Those with a history of gallbladder or kidney issues face higher risks of complications. Pregnant or breastfeeding women should avoid Wegovy due to unknown effects on the baby.
Teens using Wegovy require close monitoring for gallbladder problems or rashes. Elderly patients may be more sensitive to side effects like dehydration. Always follow your doctor’s guidance for your specific situation.
