Why am I so bloated on GLP-1s?
Still Bloated on GLP-1s? These Surprising Foods Might Be the Culprit
What to avoid (and what to try instead) when nausea and bloating just won’t quit.
Why Am I Still Bloated on GLP-1s?
You’ve started your GLP-1 medication. You’re eating less. Maybe even healthier. And yet—your stomach feels like it’s auditioning for an air balloon show.
If you’re wondering “Why am I still bloated on Mounjaro, Wegovy, or Ozempic?”—you’re not alone. This frustrating side effect is incredibly common, especially early on.
Let’s explore the unexpected food triggers—and what to eat instead—for a calmer, less gassy gut on your GLP-1 journey.
What Causes Bloating on GLP-1s?
GLP-1 medications like Mounjaro (tirzepatide), Ozempic, and Wegovy slow down digestion. That’s part of how they reduce appetite and regulate blood sugar.
- Food stays in your stomach longer
- Gas builds up more easily
- Certain ingredients become harder to process
This combination can lead to nausea, bloating, reflux, and constipation—especially when paired with common trigger foods.
7 Surprising Foods That Make You Bloat on GLP-1s
1. Cruciferous Vegetables (Broccoli, Cauliflower, Kale)
These fiber-rich veggies are high in sulfur and FODMAPs—fermentable carbs that can cause gas and bloating.
Try instead: Zucchini, carrots, spinach, or green beans (lightly cooked is easier to digest).
2. Legumes (Chickpeas, Lentils, Beans)
While nutritious, legumes are notorious for gas. Slower digestion on GLP-1s makes this worse.
Try instead: Tofu, tempeh, or small portions of canned, rinsed lentils.
3. Artificial Sweeteners (Sorbitol, Maltitol, Xylitol)
These are common in sugar-free gums, protein bars, and diet foods. They ferment in the gut and trigger bloating, gas, and diarrhea.
Try instead: Stevia or monk fruit, used sparingly. Avoid overly sweetened diet products.
4. Ultra-Processed “Diet” Foods
Low-calorie bars, shakes, and snacks often include gums, emulsifiers, and inulin—gut irritants for sensitive tummies.
Try instead: Simple, whole foods with short ingredient lists.
5. High-Fat Meals (Even Healthy Fats)
Fat takes longer to digest. On GLP-1s, it can feel heavy, triggering nausea or fullness that lasts hours.
Try instead: Smaller portions of avocado, nuts, or oily fish—paired with easy-to-digest carbs.
6. Sparkling Water & Fizzy Drinks
Carbonation = trapped gas. Even zero-calorie drinks can inflate your belly and worsen bloating.
Try instead: Flat water with lemon, or herbal teas like peppermint or ginger.
7. High-Fiber Breads, Bars, and Cereals
Fiber is key—but too much too fast = chaos. Fiber-fortified products can overwhelm the gut.
Try instead: Gradually increase soluble fiber with oats, flax, chia, and low-FODMAP fruits.
How You Eat Matters Too
It’s not just what you eat—it’s how you eat it.
- Eat slowly and chew thoroughly
- Avoid lying down after meals
- Stick to small, consistent portions
- Experiment with mini meals throughout the day
Gut-Friendly Swaps for Common Triggers

| Diet yoghurts | Plain Greek yogurt + berries |
| High-fiber cereals | Oats + ground flaxseed |
Bloating Isn’t a Failure
It’s a signal. It’s your gut saying: “Let’s recalibrate.”
Be gentle with yourself. Be curious. And most importantly—remember you’re not alone. You’re not doing it wrong. You’re resetting. That takes time, not pressure.
FAQs About Bloating on GLP-1s
Why does GLP-1 cause bloating?
These medications slow digestion. That means food and gas stay in your system longer, increasing bloating—especially if your diet isn’t gut-supportive.
What foods should I avoid on GLP-1s?
Gas-producing veggies, beans, sugar alcohols, fizzy drinks, fatty meals, and high-fiber processed products can all make symptoms worse.
How long does bloating last on GLP-1s?
For many, bloating improves after 2–3 months with mindful food choices. But it’s individual. Pay attention to your body's signals.
Can I eat fiber on GLP-1s?
Yes—but go slow. Soluble fiber (like oats and chia) is gentler than raw cruciferous veggies or fiber supplements.
