GLP-1 medications are used to treat conditions such as type 2 diabetes and, depending on the medication, chronic weight management. These treatments work on pathways involved in blood sugar regulation, appetite, and digestion. Some medications, such as tirzepatide, also act on GIP receptors.
Like any prescription medication, GLP-1 treatments can cause side effects. Understanding which symptoms are common, which may require medical attention, and how your provider monitors your treatment can help you make informed decisions about your care.
At VIVA Wellness, we are here to support you through every stage of your weight loss journey.
Common Side Effects Of GLP-1
Below are some of the side effects we frequently see with GLP-1 agonists. Later in this article, we provide a list of other possible side effects. The prescribing information for your medication includes the full list.
Gastrointestinal Issues
Nausea
Many patients report nausea, especially during the initial weeks of treatment. This can often be managed by starting with a lower dose and gradually increasing it.
How to mitigate:
- Follow your prescribed dosing schedule, which starts low and increases gradually
- Opt for smaller, more frequent meals
- Steer clear of fatty or spicy foods.
- Ensure adequate hydration
- Speak with our team at VIVA Wellness
Diarrhea
Diarrhea is another common side effect, typically mild to moderate in severity. Staying hydrated and maintaining a balanced diet can help alleviate symptoms.
How to mitigate:
- Maintain hydration by drinking ample fluids throughout the day
- Steer clear of greasy or spicy foods in your diet
- Reduce consumption of caffeine and alcohol
- Seek advice from your healthcare provider if symptoms are severe or persistent
Vomiting
Some individuals may experience vomiting, which can be distressing but usually subsides over time.
How to mitigate:
- Avoid consuming heavy, greasy, or spicy foods that can exacerbate nausea and vomiting
- Stay hydrated by drinking plenty of fluids throughout the day
- If vomiting persists or becomes severe, consult your healthcare provider for further guidance and potential anti-nausea medications that may be appropriate for you
Constipation
Constipation can occur as a side effect of GLP-1 medications, in part because they slow down the emptying of the stomach.
How to mitigate:
- Increase fiber intake
- Stay hydrated
- Exercise regularly
- Establish a routine
- Ask your provider before using over-the-counter remedies
- Manage stress
Bloating
Bloating is a common side effect of GLP-1 medications.
How to mitigate:
- Eat smaller meals
- Chew thoroughly
- Avoid gas-producing foods
- Stay hydrated
- Exercise regularly
- Consider probiotics
Fatigue
Fatigue is a common side effect of GLP-1 medications. Because they reduce appetite, some people may not eat enough food to support their energy levels.
Decreased Appetite and Weight Loss
GLP-1s can lead to a significant reduction in appetite, which may result in weight loss. While this can be beneficial for those looking to manage their weight, it might be concerning for patients who do not need to lose weight.
Less Common but Serious Side Effects
Below are some of the less common side effects we see.
Pancreatitis
There is a potential risk of pancreatitis (inflammation of the pancreas). Symptoms include severe abdominal pain, nausea, and vomiting. Patients experiencing these symptoms should seek immediate medical attention.
How to mitigate:
- If you have severe abdominal pain that won’t go away, with or without vomiting, stop taking your medication and contact your provider right away.
Hypoglycemia
When used in combination with other diabetes medications, particularly insulin or sulfonylureas, GLP-1s can increase the risk of hypoglycemia (low blood sugar levels). Symptoms include dizziness, sweating, and confusion. Your provider may recommend blood sugar monitoring and adjustments to your other diabetes medications to manage this risk.
How to mitigate:
- Monitor your blood glucose levels regularly.
- Keep fast-acting carbohydrates, such as glucose tablets, readily available.

Allergic Reactions
Although rare, some patients may experience allergic reactions to GLP-1 medications, including serious reactions such as anaphylaxis. Symptoms can range from mild (rash, itching) to severe (difficulty breathing, facial or throat swelling). Immediate medical attention is required for severe reactions.
Long-term Side Effects and Considerations
Below is a quick look at some of the long-term side effects of GLP-1 medications.
Thyroid Tumors
In studies in rodents, GLP-1 medications such as semaglutide and tirzepatide caused thyroid C-cell tumors. It is not known whether they cause these tumors, including medullary thyroid carcinoma (MTC), in humans. These medications should not be used by people with a personal or family history of MTC or multiple endocrine neoplasia syndrome type 2 (MEN 2). Tell your provider if you notice a lump or swelling in your neck, trouble swallowing, or shortness of breath.
Cardiovascular Effects
GLP-1 medications can increase resting heart rate. If you have a history of heart problems, your provider will review this before treatment and monitor you during treatment.
Managing Side Effects
Below are some quick tips for managing side effects.
Gradual Dose Adjustment
Starting with a lower dose and gradually increasing it can help minimize gastrointestinal side effects.
Regular Monitoring
Routine check-ups, and blood sugar monitoring when recommended, can help detect and manage potential side effects early.
Communication with Healthcare Providers
Open communication with healthcare providers about any side effects experienced is crucial for effective management and adjustment of the treatment plan.
