Ozempic, a medication used to manage type 2 diabetes, has become widely known for its blood sugar control and weight loss effects. Its active ingredient, semaglutide, mimics a hormone that regulates blood sugar and appetite.
While it offers significant benefits, many users experience side effects that can range from mild to severe.
This article explores what are the bad side effects of Ozempic in simple language, helping you understand the risks and how to manage them.
Understanding Ozempic and Its Uses
Ozempic is a weekly injection prescribed for adults with type 2 diabetes. It helps lower blood sugar levels and reduces the risk of heart attack, stroke, or kidney issues in some patients.
The drug belongs to a class called GLP-1 receptor agonists, which work by boosting insulin production and slowing digestion. Though effective, it’s not suitable for type 1 diabetes or those with a history of pancreatitis.
Some people use Ozempic off-label for weight loss, as it suppresses appetite. This has made it popular, but the FDA has not approved it for this purpose. Using it without medical guidance can increase the risk of side effects. Always consult a doctor before starting Ozempic to ensure it’s right for you.
Common Side Effects of Ozempic
Most side effects of Ozempic are mild and affect the digestive system. These issues often occur when starting the medication or increasing the dose. They tend to improve as your body adjusts. However, they can still be bothersome for many users.
Gastrointestinal Issues
Nausea is the most common side effect, affecting about 15-23% of users in clinical trials. It’s usually mild but can cause discomfort or an urge to vomit. This often happens early in treatment or after a dose increase. Eating smaller meals or avoiding greasy foods may help.
Diarrhea affects around 8-14% of users, causing loose or watery stools. It typically lasts a week or so and is most common at the start of treatment. Staying hydrated is key to managing this side effect. Avoiding sugary drinks or dairy can also reduce symptoms.
Constipation is less frequent, occurring in 3-7% of users. It may cause infrequent or difficult bowel movements, often in the first month. Drinking plenty of water and adding fiber-rich foods like fruits and vegetables can ease this issue.
Bloating and burping are also reported, sometimes with a foul smell described as “rotten eggs.” These effects, known as abdominal distension or eructation, are less common but can be unpleasant. They often fade as the body adjusts to the medication.
Fatigue and Dizziness
Some users feel tired or lack energy while taking Ozempic. This may stem from reduced appetite, leading to lower calorie intake. About 0.4% of trial participants reported fatigue. If it persists, a doctor can suggest ways to boost energy levels.
Dizziness, also reported by about 0.4% of users, can feel like lightheadedness or unsteadiness. It may be linked to low blood sugar, especially if Ozempic is taken with other diabetes medications like insulin. Checking blood sugar levels regularly can help manage this.
Serious Side Effects to Watch For
While most side effects are mild, Ozempic can cause serious issues in rare cases. These require immediate medical attention and can have long-term consequences. Knowing what are the bad side effects of Ozempic can help you act quickly if they occur.
Pancreatitis
Pancreatitis, or inflammation of the pancreas, is a rare but serious side effect. Symptoms include severe upper stomach pain that may spread to the back, often with vomiting.
Clinical trials showed no clear link between Ozempic and pancreatitis, but some users have reported it. If you experience these symptoms, stop taking Ozempic and contact your doctor immediately.
Low Blood Sugar (Hypoglycemia)
Ozempic can cause low blood sugar, especially when combined with insulin or sulfonylureas. Symptoms include shakiness, sweating, confusion, or dizziness. This can be dangerous if untreated, so monitor blood sugar levels closely. Always keep a quick source of sugar, like glucose tablets, on hand.
Thyroid Tumors and Cancer Risk
Ozempic carries a boxed warning from the FDA about the risk of thyroid tumors, including medullary thyroid carcinoma (MTC). Animal studies showed this risk, but it’s unclear if it applies to humans. Symptoms like a lump in the throat or difficulty swallowing should be checked by a doctor. Those with a family history of thyroid cancer should avoid Ozempic.
Kidney Problems
Ozempic may lead to kidney injury, often due to dehydration from vomiting or diarrhea. In rare cases, this can cause permanent damage, especially in those with existing kidney issues. Signs include reduced urination or swelling in the legs. Regular blood tests can help monitor kidney health.
Gallbladder Issues
Gallbladder problems, like gallstones, occurred in 1.5% of Ozempic users in trials, compared to 0.4% on placebo. Symptoms include sharp pain in the upper right abdomen or yellowing of the skin. Seek medical help if these appear, as gallbladder issues can require surgery.
Vision Problems
Ozempic may worsen diabetic retinopathy, an eye condition linked to diabetes. About 3% of users in a two-year study had complications, compared to 1.8% on placebo. Another rare issue is non-arteritic anterior ischemic optic neuropathy (NAION), which can cause vision loss. Report any vision changes to your doctor immediately.
Allergic Reactions
Severe allergic reactions to Ozempic are rare but can be life-threatening. Symptoms include swelling, rash, or difficulty breathing. If these occur, stop using Ozempic and seek emergency care. Mild rashes may be manageable, but always consult your doctor.
Long-Term Side Effects
Some side effects of Ozempic can persist or appear after long-term use. These are less common but can impact quality of life. Understanding these risks is crucial for long-term users.
Ozempic Face
“Ozempic face” refers to facial changes due to rapid weight loss, such as sagging skin or increased wrinkles. This happens because facial fat, which supports skin elasticity, decreases quickly. Cosmetic treatments like fillers may help, but weight loss should be gradual to minimize this effect.
Mental Health Concerns
Some users report mental health issues, like anxiety, depression, or suicidal thoughts, while taking Ozempic. The FDA is monitoring these reports, though a direct link isn’t confirmed. Obesity itself can increase mental health risks, so it’s hard to pinpoint the cause. Discuss any mood changes with your doctor.
Weight Regain
Ozempic is often used off-label for weight loss, but stopping the drug can lead to regaining lost weight. This can be frustrating and may contribute to weight cycling, which is linked to health issues like binge eating disorder. A supervised diet and exercise plan can help maintain weight loss.
Managing Side Effects of Ozempic
Many side effects can be managed with simple strategies. These tips can help reduce discomfort and improve your experience with Ozempic.
- Eat smaller, frequent meals to reduce nausea and bloating.
- Stay hydrated to prevent dehydration from diarrhea or vomiting.
- Avoid trigger foods like greasy, fried, or sugary items.
- Monitor blood sugar to catch hypoglycemia early.
- Exercise regularly to help with constipation and energy levels.
- Talk to your doctor about dose adjustments if side effects persist.
For serious side effects, immediate medical attention is essential. Always follow your doctor’s guidance and report any unusual symptoms.

Special Considerations
Certain groups may face higher risks from Ozempic. Women may experience side effects more often than men, though the reasons aren’t fully clear. People with kidney or liver disease should use Ozempic cautiously, as it may worsen these conditions. Pregnant or breastfeeding women should avoid Ozempic due to unknown risks to the baby.
Off-label use for weight loss is a growing trend, but it’s not without risks. Social media has popularized Ozempic for non-diabetic weight loss, sometimes leading to misuse. This can cause shortages for those who need it for diabetes, as seen in 2024. Always use Ozempic under medical supervision to avoid complications like overdose.
Summary
Ozempic is a powerful medication for type 2 diabetes, offering benefits like better blood sugar control and weight loss. However, what are the bad side effects of Ozempic can range from mild issues like nausea and diarrhea to serious ones like pancreatitis, kidney problems, or thyroid tumors.
Most side effects are temporary and manageable, but some can have lasting impacts. By understanding these risks and working closely with your doctor, you can use Ozempic safely and effectively.
Always report severe symptoms immediately and follow your prescribed treatment plan.
