Ozempic and Hemorrhoids: What’s the Connection?
If you’ve developed a hemorrhoid or noticed new anal pain since starting a GLP-1 medication like Ozempic, Wegovy, Mounjaro, or Zepbound, you’re not imagining the connection. It’s not a direct side effect these drugs cause on their own, it happens through constipation, and constipation is one of the most well-documented side effects of this entire drug class.
How this actually happens
GLP-1 and dual GIP/GLP-1 medications work partly by slowing gastric emptying, the rate food moves through your digestive system. That’s a big part of why they’re effective for blood sugar control and appetite reduction. It’s also why they commonly cause constipation: slower transit means stool spends more time in the colon, where more water gets reabsorbed from it, leaving it harder and drier.
Harder stool means more straining. And straining is one of the single most well-established, modifiable risk factors for both hemorrhoids and anal fissures. When you strain, pressure increases directly on the venous cushions in the anal canal, the tissue that becomes a hemorrhoid when it’s repeatedly engorged and irritated. That same pressure and hard stool passage is what tears the lining of the anus in a fissure.
Reduced appetite compounds the problem. Eating and drinking less on a GLP-1 medication often means less fiber and fluid intake, both of which make stool harder and constipation worse.
This isn’t a rare or unusual reaction
Depending on the specific medication and dose, published constipation rates for GLP-1 and GIP/GLP-1 drugs range from roughly 3% to as high as 24-26% Given how common constipation is across this drug class, and how directly straining drives hemorrhoid and fissure development, it’s a completely logical, expected downstream effect for a meaningful number of people, even if it’s not listed as a direct side effect on the drug label itself.
For the specific numbers on your medication, see our guides to Mounjaro constipation and semaglutide constipation (covering Ozempic, Wegovy, and Rybelsus), or the broader overview at ozempic constipation.
Signs it’s more than just constipation
- Sharp, tearing pain during or after bowel movements that can last minutes to hours, the hallmark symptom of an anal fissure
- Bright red blood on toilet paper, in the bowl, or on stool
- A new lump, swelling, or persistent itching around the anus, common signs of a hemorrhoid
- Pain or discomfort that doesn’t improve even as your GLP-1-related constipation gets better
Why managing constipation alone often isn’t enough
Fiber, hydration, and movement are the right first steps for GLP-1-related constipation, and they genuinely help prevent hemorrhoids and fissures from developing in the first place. But if a fissure or hemorrhoid has already formed, softer stool alone usually isn’t enough to heal the tissue itself. A fissure especially tends to get stuck in a cycle: pain causes muscle spasm, spasm reduces blood flow, and reduced blood flow slows healing, regardless of how soft your stool is at that point.
That’s the point where targeted treatment matters more than continuing to manage the constipation side alone. Bummed offers prescription treatment for both anal fissures and hemorrhoids through online evaluation, designed specifically to address the underlying tissue issue, not just the stool consistency that triggered it.
Frequently Asked Questions About GLP-1 Medications and Hemorrhoids
Can Ozempic actually cause hemorrhoids?
Not directly. Ozempic (semaglutide) doesn’t cause hemorrhoids as a listed side effect, but it commonly causes constipation, and constipation-related straining is one of the best-established causes of hemorrhoids. The connection is indirect but very real for people who develop significant constipation on the medication.
Which GLP-1 medications are most likely to lead to this?
Medications with higher weight-management doses tend to cause more constipation, and therefore carry more indirect risk. Wegovy and Zepbound (the higher-dose weight-management versions of semaglutide and tirzepatide) show notably higher constipation rates than Ozempic and Mounjaro (the lower-dose diabetes versions of the same drugs).
Will fixing my constipation make the hemorrhoid go away?
Sometimes, especially with a mild, early hemorrhoid. But if it’s become persistently swollen, painful, or prone to bleeding, softer stool alone often isn’t enough, the tissue itself may need targeted treatment to fully resolve.
Should I stop my GLP-1 medication if I develop a hemorrhoid or fissure?
Don’t stop or adjust your GLP-1 medication without talking to your prescriber. In most cases, the constipation and the hemorrhoid or fissure can both be managed while you continue treatment, they’re not usually a reason to discontinue a medication that’s otherwise working well for you.
