Common side effects of GLP-1 medications

Updated this week

Common side effects of GLP-1 medications

GLP-1 (glucagon-like peptide-1) therapies, including semaglutide (GLP-1 receptor agonist) and tirzepatide (GLP-1 + GIP receptor agonist), are powerful tools for supporting weight management and blood sugar control. While most people tolerate them well, side effects can occur—especially when first starting or adjusting your dose.

At Shed, your well-being comes first. Licensed providers partnered with Shed are available to support you and address any concerns you may have.


What you might experience

Note: Side effects vary from person to person. Most are mild and temporary. Always talk to your provider if you have concerns.

  1. Nausea
    One of the most common side effects, often temporary and improving as your body adjusts.

  2. Vomiting
    Can occur, especially after a dose increase. Staying hydrated and eating small, bland meals may help.

  3. Diarrhea
    Some patients notice looser stools while their digestive system adapts.

  4. Constipation
    A frequent digestive change. Drinking water, adding fiber, and staying active can help.

  5. Decreased Appetite
    A primary goal of GLP-1 medications—just be sure to maintain a balanced, nutrient-rich diet.

  6. Abdominal Discomfort or Bloating
    May be related to delayed gastric emptying, which can cause a sensation of prolonged fullness.

  7. Fatigue
    Some patients report feeling more tired than usual during dose adjustments.

  8. Headache
    Generally mild and often improves over time.

  9. Indigestion
    Can show up as heartburn, stomach upset, or slower digestion.

  10. Injection Site Reactions

    Redness, swelling, or mild discomfort at the injection site are possible but usually short-lived.

What to Know:

Gastrointestinal (GI) side effects—like nausea, vomiting, and bloating—are the most common and are typically dose-related. This means they often appear or worsen after a dose increase but tend to settle as your body adjusts over time.
Some patients also experience delayed gastric emptying, which can lead to a sensation of prolonged fullness or bloating. You might not immediately recognize it as a side effect, but if you’re feeling unusually full for hours after eating or noticing slower digestion, this could be why.


Serious but Rare Complications:

While uncommon, serious potential complications associated with GLP-1 medications include pancreatitis, gallbladder problems, and elevations in kidney function tests. Patients should promptly report severe abdominal pain, jaundice, significant changes in urination, or swelling to their healthcare provider.
