The popular drug Ozempic has gained considerable attention in recent years as an effective treatment for type 2 diabetes. As a glucagon-like peptide-1 (GLP-1) receptor agonist, it helps regulate blood sugar levels and promote weight loss by mimicking the hormone incretin, which stimulates insulin secretion and suppresses appetite.
While its benefits are well-documented, it’s essential to understand the potential side effects before starting this medication.
In this article, we’ll explore Ozempic side effects that you should be aware of. Understanding these risks can help you make informed decisions in consultation with your healthcare provider.
Common Side Effects of Ozempic
The most common side effects of Ozempic are generally mild and often improve as the body adjusts to the medication. However, they can be bothersome initially and should not be ignored. Some of the frequently reported side effects include:
1. Nausea
Nausea is the most commonly reported side effect when beginning Ozempic, affecting nearly 21% of participants in clinical trials. This occurs because Ozempic slows gastric emptying, leading to a sensation of fullness.
In many cases, nausea tends to subside after a few weeks as the body adjusts to the medication. However, studies indicate that nausea can recur with each dose increase. Therefore, if your dose is raised, nausea may return even after you’ve started feeling better.
2. Diarrhea
In clinical trials, diarrhea was the third most commonly reported side effect, with about 8% of Ozempic users experiencing it. This side effect is linked to Ozempic’s interaction with the digestive system.
Research suggests that diarrhea may occur because Ozempic alters the body’s nutrient absorption process. Additionally, Ozempic slows down stomach emptying and overall digestive tract movement. In some individuals, this slowing effect can trigger the stooling reflex, resulting in diarrhea.
According to a 2022 study, diarrhea usually begins within the first four weeks of treatment and then decreases significantly. For most people, symptoms last about three days.
3. Vomiting
Vomiting can occur, particularly in the early stages of taking Ozempic. In the same clinical trials, vomiting affected 9% of participants. Like nausea, this side effect often lessens after the initial weeks of treatment as the body adjusts.

Real Housewives of Dubai star Caroline Stanbury shared that while on Ozempic, she once “projectile vomited” at a bar! It’s a reminder that everyone reacts differently to medications, even celebrities!
4. Stomach (abdominal) Pain
In clinical trials, approximately 1 in 14 people experienced abdominal pain, which could manifest as cramps, aching, bloating, or gas discomfort. Starting with a low dose and gradually increasing it may help minimize these symptoms.
5. Constipation
Constipation, while less common than nausea or diarrhea, is still a notable side effect for some patients on Ozempic. Clinical trials revealed that 3% to 5% of participants experienced constipation, with more recent studies showing this figure may be as high as 4% to 12%. The incidence could be even higher among those using Ozempic for off-label purposes.
One study found that Ozempic-related constipation can last up to six weeks, or about 47 days. A key factor contributing to this issue is insufficient fiber intake. Fiber helps add bulk to stool, making it easier to pass, but since Ozempic often reduces overall food consumption, many people might inadvertently eat less fiber.
Serious Side Effects of Ozempic
Although rare, Ozempic may cause severe side effects requiring immediate medical attention. Knowing these risks and discussing any concerns with your doctor before beginning treatment is crucial.
1. Pancreatitis
Pancreatitis, or inflammation of the pancreas, is a potentially life-threatening condition linked to GLP-1 receptor agonists like Ozempic.
In glycemic control trials, acute pancreatitis was confirmed in 7 Ozempic-treated patients (0.3 cases per 100 patient-years) compared to 3 patients in the comparator group (0.2 cases per 100 patient-years). One patient on Ozempic developed chronic pancreatitis.
In a 2-year trial, 8 patients on Ozempic (0.27 cases per 100 patient-years) and 10 on placebo (0.33 cases per 100 patient-years) developed acute pancreatitis, with both groups receiving standard care.
Symptoms of pancreatitis include:
-
- Severe abdominal pain accompanied by nausea and vomiting
- Abdominal tenderness, especially in the upper part
- Fever
- Rapid pulse
- The abdomen might appear swollen or feel bloated
- Loss of appetite
- Unexplained weight loss
If any of these symptoms occur, especially after starting a medication like Ozempic, you should seek medical attention immediately.
2. Kidney Damage
There have been reports of acute kidney injury and worsening of chronic kidney failure in patients using GLP-1 receptor agonists like Ozempic. In some cases, this has required dialysis. These kidney issues can occur even if you don’t have prior kidney problems. Most cases involved severe nausea, vomiting, diarrhea, or dehydration.
A 2021 study investigated two cases where patients with chronic kidney disease (due to diabetic kidney disease) experienced a rapid decline in kidney function after being prescribed semaglutide. Both patients saw their kidney function worsen significantly, with increased levels of protein in their urine, which is a sign of kidney damage.
In one patient, a kidney biopsy revealed severe kidney damage, including scarring (glomerulosclerosis), inflammation, and signs of acute injury to the kidney’s filtering units (tubules).
It’s important to monitor your kidney function, especially when starting or increasing your dose of Ozempic. Staying well-hydrated and promptly addressing any gastrointestinal symptoms can help reduce the risk of kidney complications.
3. Thyroid Cancer Risk
Ozempic carries a boxed warning for thyroid C-cell tumors, including medullary thyroid carcinoma (MTC). Although this risk has primarily been observed in rodent studies, it remains unclear if the same risk applies to humans.
The FDA has advised against using Ozempic in individuals with a personal or family history of MTC or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). According to research published in the Journal of Clinical Endocrinology & Metabolism, long-term human studies are needed to fully understand the potential cancer risk.
4. Hypoglycemia (Low Blood Sugar)
Hypoglycemia, or low blood sugar, is more commonly associated with insulin therapy or sulfonylureas. However, if Ozempic is used alongside these medications, it can increase the risk of hypoglycemia.
Symptoms of hypoglycemia include shakiness, sweating, confusion, dizziness, and, in severe cases, loss of consciousness. To reduce the risk, it’s essential to monitor blood sugar levels frequently if you’re on a combined treatment regimen and discuss with your doctor how to adjust doses accordingly.
5. Gallbladder Disease
Acute gallbladder problems, like gallstones (cholelithiasis) or inflammation of the gallbladder (cholecystitis), have been reported in trials and after market approval of GLP-1 receptor agonists, including Ozempic. In placebo-controlled trials, 1.5% of patients taking Ozempic 0.5 mg and 0.4% taking Ozempic 1 mg experienced gallstones, while no cases were reported in the placebo group.
Symptoms of gallbladder disease include severe upper abdominal pain, nausea, vomiting, and jaundice. If you notice any of these signs, it is crucial to contact your healthcare provider.
6. Retinopathy (Eye Problems)
Diabetic retinopathy is a complication of diabetes that can lead to vision loss. In a 2-year trial involving patients with type 2 diabetes and high cardiovascular risk, more cases of diabetic retinopathy complications were observed in those treated with Ozempic (3.0%) compared to those on a placebo (1.8%).
The risk was higher in patients who already had diabetic retinopathy at the start of the study–8.2% for Ozempic users versus 5.2% for placebo. For those without a history of diabetic retinopathy, the risk was lower but still slightly higher with Ozempic (0.7%) compared to placebo (0.4%).
Rapid improvements in blood sugar control can sometimes temporarily worsen diabetic retinopathy. However, the long-term effects of Ozempic on diabetic retinopathy complications have not been fully studied. If you have a history of diabetic retinopathy, it’s important to have regular eye exams to monitor for any progression of the condition while using Ozempic.
If you notice changes in your vision, such as blurriness or dark spots, report these symptoms to your doctor immediately.
7. Allergic Reactions
Serious allergic reactions, such as anaphylaxis and angioedema, have been reported in some patients taking Ozempic. Signs of a severe allergic reaction include difficulty breathing, swelling of the face or throat, and hives.
If you experience any signs of a severe allergic reaction, you should stop using Ozempic immediately, seek prompt medical treatment, and be monitored until the symptoms resolve. Ozempic should not be used if you’ve had a previous allergic reaction to it.
Tips to Manage & Minimize Side Effects
While many side effects of Ozempic subside over time, there are steps you can take to manage them:
- Start with a low dose: Begin with the lowest dose of Ozempic as prescribed by your healthcare provider. Gradually increasing the dose allows your body to adjust and can help reduce the risk of side effects like nausea and gastrointestinal issues.
- Eat smaller, more frequent meals: Eating smaller meals throughout the day instead of large meals can help reduce nausea and bloating. Avoid fatty or fried foods, which can worsen these symptoms.
- Stay hydrated: Drink plenty of water throughout the day, especially if you experience vomiting, diarrhea, or dehydration. Staying hydrated can help prevent kidney complications and reduce gastrointestinal discomfort.
- Monitor blood sugar levels: Regularly check your blood sugar levels, especially if you’re taking Ozempic with insulin or other diabetes medications. This helps in managing the risk of hypoglycemia (low blood sugar).
- Recognize the signs of hypoglycemia: Be aware of hypoglycemia symptoms like shakiness, sweating, dizziness, or confusion. Carry quick sources of sugar, such as glucose tablets or candy, to manage low blood sugar if it occurs.
- Gradually increase physical activity: If you’re starting a new exercise routine while on Ozempic, increase your activity level gradually. This helps your body adapt without triggering blood sugar swings or gastrointestinal symptoms.
- Take Ozempic on the same day each week: Consistency in taking Ozempic on the same day every week helps your body maintain a steady level of the medication, reducing the likelihood of side effects.
- Report any severe symptoms: Contact your healthcare provider if you experience severe or persistent side effects, such as intense abdominal pain, symptoms of pancreatitis, or allergic reactions like swelling or difficulty breathing.
- Avoid alcohol: Limit alcohol consumption as it can increase the risk of hypoglycemia and gastrointestinal discomfort. Discuss with your healthcare provider how alcohol might affect your treatment with Ozempic.
- Regular monitoring: Have regular check-ups to monitor your kidney function, eye health (if you have diabetic retinopathy), and overall progress while on Ozempic. This ensures any potential side effects are caught and managed early.
By following these tips and maintaining open communication with your healthcare provider, you can effectively manage and minimize the side effects of Ozempic.
Wrap-up
Ozempic has shown tremendous promise in managing type 2 diabetes and aiding in weight loss. However, like any medication, it comes with potential side effects. While most of these side effects are mild and manageable, there are some more serious risks, such as pancreatitis, kidney damage, and thyroid cancer, that require careful consideration.
Before starting Ozempic, thoroughly discuss with your healthcare provider to weigh the benefits against the potential risks. You can work with your doctor to ensure the best possible outcome by staying informed and vigilant about the side effects.
