Ozempic, the brand name of the generic drug semaglutide, is approved by the U.S. Food and Drug Administration (FDA) to help manage blood sugar in people with type 2 diabetes. It’s also often prescribed off-label to support weight loss in people living with obesity.

A higher-dose version of semaglutide, called Wegovy, is FDA-approved specifically for long-term weight management in people with obesity and certain health conditions. Semaglutide — also sold as the oral formula Rybelsus — works mainly by helping control blood sugar. Semaglutide also supports weight management, promotes heart health, and may boost energy and enhance overall quality of life.

Some people who use semaglutide often find they feel more in control of their hunger. Some also say it’s easier to stick with healthy eating routines and make better food choices. With guidance from a healthcare provider, semaglutide can be a powerful tool for managing long-term health conditions.

Beyond the Basic Benefits

In addition to lowering blood sugar and supporting weight loss, semaglutide may reduce the risk of heart attacks and strokes in people with type 2 diabetes and heart disease. It can also lead to lower blood pressure, reduced inflammation, and better cholesterol levels. Some people notice improvements in sleep, mood, and overall daily functioning.

These benefits can help people stick with long-term health changes and may even encourage them to make other changes, like being more active or drinking less alcohol. Some also find that it helps reduce cravings for snacks and sweets. Semaglutide is often just one part of a bigger care plan focused on improving overall wellness.

How Semaglutide Works in the Body

Semaglutide is part of a class of drugs known as glucagon-like peptide-1 (GLP-1) receptor agonists. These medications work by mimicking GLP-1, a natural hormone that plays a key role in managing blood sugar and appetite.

When taken weekly as an injection, semaglutide helps the body release insulin when blood sugar levels rise. It also slows down how quickly food leaves the stomach and signals to the brain that the body is full. This combination results in better blood sugar control and fewer hunger signals.

By making you feel full faster and longer, semaglutide helps reduce overall calorie intake. This is especially helpful for people trying to lose weight or avoid gaining weight they’ve lost through diet and exercise.

Understanding the Risks

Although semaglutide is safe for most people, it’s important to know about potential side effects. One rare but serious risk is pancreatitis, which means inflammation of the pancreas.

Pancreatitis can come on suddenly and may require immediate medical attention. That’s why it’s important to recognize the symptoms and get help right away.

What Is Pancreatitis?

The pancreas is a small organ that sits behind the stomach. It helps your body digest food and makes insulin. When the pancreas becomes inflamed, the digestive enzymes it produces can start to damage the pancreas itself. This can lead to serious problems.

The two types of pancreatitis are acute (sudden and short-term) and chronic (long-term and recurring). Both can be dangerous if not treated early. In some cases, pancreatitis can lead to organ damage, infection, or life-threatening complications.

Risk Factors for Pancreatitis

Not everyone is at risk, but some people are more likely to develop pancreatitis. Risk factors include:

• A personal or family history of pancreatitis
• Gallstones
• Heavy alcohol use
• Alcohol consumption during treatment with GLP-1 receptor agonists
• High triglyceride levels (above 400 milligrams per deciliter, but your doctor can be cautious even at lower levels, as the upper limit is 150 milligrams per deciliter)
• Certain medications, including other GLP-1 drugs

If you have any of these risk factors, talk to your doctor before starting semaglutide. Your healthcare provider can help you weigh the risks and benefits and decide if this medication is right for you.

Recognizing the Symptoms of Pancreatitis

Symptoms of pancreatitis can be very different from mild stomach discomfort some people experience when starting semaglutide. Pancreatitis pain is stronger and lasts longer than typical stomach pain. It often begins in the upper belly and may spread to the back. You might experience:

• Severe, constant abdominal pain
• Pain that worsens after eating
• Nausea or vomiting that doesn’t go away
• Swollen or tender abdomen
• Fever or chills
• Fatigue or weakness
• A rapid heart rate

These symptoms can show up suddenly and may not improve with rest or over-the-counter treatments. If you experience these signs, do not wait — contact your doctor immediately or go to the emergency room.

What the Research Says

Research on the risk of acute pancreatitis in people taking GLP-1 receptor agonists like semaglutide has shown mixed results. One large study suggests there could be a connection but highlights the need for close monitoring. Another analysis also found that while there is some evidence of a slight increase in pancreatitis cases, the overall risk remains very low.

A 2024 study evaluating real-world data reported similar findings, suggesting that the absolute risk of pancreatitis is minimal, especially compared to the overall benefits of GLP-1 therapies.

Doctors generally agree that although the chance of pancreatitis exists, it’s rare. Monitoring symptoms and communicating with your healthcare provider is the safest approach.

What To Expect if Pancreatitis Is Diagnosed

If your doctor suspects pancreatitis, they will likely order blood tests to check enzyme levels, along with imaging tests like an ultrasound or CT scan. If the diagnosis is confirmed, you will be instructed to stop using semaglutide immediately.

Treatment depends on the severity of the condition. In more serious cases, hospitalization may be required. Treatment in the hospital may include intravenous (through a vein) fluids, pain relief, and nutritional support.

Most people recover from acute pancreatitis on their own. After recovery, your doctor will discuss long-term plans with you. If semaglutide causes the condition, you likely won’t be able to restart the medication. Your provider will help you explore other treatment options.

Staying Safe While Using Semaglutide

Awareness is key. Before you begin taking semaglutide, talk to your doctor about your medical history, especially if you’ve ever had pancreatitis or gallbladder issues. Ask what symptoms to watch for and what to do if they arise.

You can take steps to stay safe:

• Keep track of any changes in how your stomach feels.
• Note if you feel unusually full or nauseous or have unexplained pain.
• Share new symptoms with your care team, even if they seem small.

Regular check-ins with your provider can catch issues early. Your doctor may also order blood tests during treatment to monitor your levels, especially if you’ve had digestive issues in the past.

Semaglutide and a Healthier Lifestyle

Semaglutide is most effective when paired with a complete lifestyle plan. That means building habits that support your overall health.

Consider the following additions to your routine:

• Work with a nutritionist to design a meal plan that works for you.
• Increase your daily activity — walk, bike, or take a fitness class.
• Join a support group for weight management or diabetes care.
• Use an app to track your food, movement, and how you feel each day.

You don’t have to make all the changes at once. Start with small, manageable steps. As you begin to feel better, it gets easier to stay motivated and stick with your goals.

Support systems make a difference. Talk with family and friends about your plan, and invite them to be part of your daily routines. When the people around you understand what you’re working toward, they can encourage you and help you keep going. The more support you have, the more likely your health changes will stick.
