GLP-1 Constipation Relief: What Actually Works (According to Thousands of Reddit Users)
Last updated: April 2026 | Reading time: 8 minutes
You haven't pooped in 7 days. Your stomach hurts. You're bloated, uncomfortable, and maybe even a little scared.
Welcome to the club. Constipation is one of the most common -- and most miserable -- side effects of GLP-1 medications like Ozempic, Wegovy, Mounjaro, and Zepbound. And if you're on one of these drugs, chances are you've gone through (or are going through) this right now.
We dug through thousands of Reddit comments from people taking GLP-1s. Here's what they said, what worked, and what didn't. No fluff. Just real talk -- and real solutions.
Why GLP-1s Back You Up
GLP-1 medications work by slowing down how fast your stomach empties food. That's great for controlling blood sugar and making you feel full. But it also means everything moves slower through your whole digestive system -- including, well, poop.
One Reddit user put it bluntly:
"Pooping less than 3 times a week is medically considered constipation."
Translation: If you're going less than every other day, your body is telling you something. And you're not alone. Thousands of GLP-1 users deal with this daily.
What Real Users Are Saying
"I can't poop. I go 7-10 days without going and my stomach hurts so bad. I just bought miralax and have had very minimal success with it."
"Constipation is really my only side effect and MiraLax has been the best thing to help! I have also read it works faster on an empty stomach."
These aren't outliers. Scroll any GLP-1 subreddit and you'll find the same story: users desperate for relief, trying everything, and sharing what finally works.
What Actually Helps
1. MiraLAX (Polyethylene Glycol)
This was the #1 product mentioned by Reddit users. It's an osmotic laxative, which means it pulls water into your intestines to soften things up. It's gentle, non-habit-forming, and available over the counter.
Affiliate pick: MiraLAX Powder for Constipation Relief, 30 Doses -- mix it in water, juice, or a warm drink. Tasteless and effective. Users report best results when taken on an empty stomach.
2. Magnesium Citrate
Magnesium citrate is another osmotic laxative that many users swear by. It works similarly to MiraLAX but can be a bit stronger. Start with a low dose and increase slowly.
Affiliate pick: Magnesium Citrate Supplement, 400mg -- Gentle & Effective
3. Fiber Supplements (Use with Caution)
Fiber can help, but here's the catch: if you're dehydrated (common on GLP-1s), adding fiber without enough water can make constipation worse. If you try fiber, load up on water too.
Affiliate pick: Metamucil Multi-Health Fiber Powder -- Sugar-Free -- mix with plenty of water.
4. Probiotics
Probiotics won't give you immediate relief, but they can support long-term gut health. Many users add them to their daily routine.
5. Hydration & Electrolytes
GLP-1s can dehydrate you quickly, especially if you're not eating much. Dehydration = harder, drier stool. Drink water throughout the day, and consider electrolyte drinks.
What to Avoid
- Stimulant laxatives (Dulcolax, Ex-Lax): These work fast but can cause cramping and dependency. Save them for emergencies, not daily use.
- Too much fiber without water: This can back up even more. If you add fiber, double your water intake.
- Processed, low-fiber foods: White bread, white rice, and cheese can all slow things down further.
- Ignoring the urge: When your body says "go," go. Delaying makes stool harder and drier.
When to See a Doctor
Constipation is common on GLP-1s, but some situations need medical attention. Call your provider if:
- You haven't had a bowel movement in 7+ days despite trying remedies
- You're in severe abdominal pain (not just discomfort)
- You're vomiting or can't keep fluids down
- You see blood in your stool
- You're losing weight rapidly without trying
Don't be embarrassed to talk to your doctor about this. They've heard it all. And they may have prescription options (like Linzess or Trulance) if OTC products aren't enough.

FAQs
Is constipation on GLP-1s permanent?
For many users, constipation improves over time as the body adjusts. But some people need ongoing management. Don't be afraid to use products like MiraLAX long-term -- they're safe for extended use when used as directed.
Can Zofran (anti-nausea med) make constipation worse?
Yes. Zofran (ondansetron) is notorious for causing constipation. One Reddit user described a "vicious cycle" of Zofran treating nausea but creating worse constipation. If this is you, talk to your doctor about alternatives or adjusting your dose.
What foods help with constipation on GLP-1s?
Prunes, kiwi, papaya, and warm liquids (like coffee or herbal tea) in the morning can help. Also try small portions of high-fiber foods like oatmeal, berries, and leafy greens. Avoid large meals -- they can overwhelm a slow digestive system.
How much water should I drink?
Aim for at least 64-80 oz per day, more if you're active or in a hot climate. GLP-1s can dehydrate you quickly, and water is essential for keeping stool soft. Add electrolytes if you're feeling fatigued or dizzy.
