This is a very common side effect and can occur in more than 1 in 10 people taking Mounjaro or Wegovy. You’re most likely to experience stomach pain when you first start your medication and when you increase your dose.
How you manage the pain depends on the type you’re experiencing:
Trapped windUsually feels like bloating or pressure in your stomach, sometimes with burping or gas. To ease trapped wind:
- Eating small and frequent meals
- Chewing food slowly with your mouth closed
- Going for a walk
- Drinking peppermint tea
Stomach cramps usually feel like sharp, intermittent pains that often come in waves.
Here’s what we recommend:
- Avoiding spicy or greasy foods
- Holding a heat pack to your stomach
- Chewing food slowly
Dull or aching stomach pain usually feels like constant low level ache in either the upper or lower abdomen.
Here’s what we recommend:
