Bloating / Gas
Feeling of fullness, tightness, or swelling in the abdomen, often accompanied by increased gas or flatulence
Prevalence
10-20% of patients
Severity
Common
Category
Gastrointestinal
Why It Happens
Delayed gastric emptying means food ferments longer in the stomach and intestines, producing excess gas. Changes in gut motility can trap gas in the intestines. Shifts in the gut microbiome caused by altered digestion patterns also contribute to increased gas production.
Timeline
Common in the first several weeks of treatment. May persist if eating habits are not adjusted. Usually improves with dietary modifications and as the body adapts to the medication.
Management Tips
Eat slowly and chew food thoroughly
Avoid gas-producing foods like beans, broccoli, cabbage, and onions initially
Limit carbonated beverages and chewing gum
Take a walk after meals to promote gas movement
Consider simethicone (Gas-X) for acute bloating
Try a digestive enzyme supplement with meals
Avoid drinking through straws (swallowing air)
When to See Your Doctor
If bloating is severe and painful, accompanied by inability to pass gas, or associated with significant abdominal distension that does not resolve

Why does Ozempic make you bloated?
GLP-1 medications slow gastric emptying, meaning food stays in your stomach and intestines longer. This extended transit time allows more bacterial fermentation, producing excess gas. Eating large meals or gas-producing foods exacerbates the effect.
How do you reduce bloating on GLP-1 medication?
Eat smaller meals, chew thoroughly, avoid carbonated drinks and gas-producing foods, walk after meals, and consider digestive enzymes or simethicone. A probiotic may also help balance gut bacteria and reduce gas production.
Is bloating a sign that GLP-1 medication is working?
Bloating indicates that gastric emptying is being slowed by the medication, which is part of its mechanism. However, bloating itself is a side effect to manage, not a measure of therapeutic effectiveness.
