Can Hemorrhoids Cause Gas or Bloating?

Can Hemorrhoids Cause Gas or Bloating?

Personally Researched | Last Updated: August2026 | Based on Clinical Studies & Personal Experience.

If you're dealing with hemorrhoids and also noticing more gas, bloating, or trouble controlling flatulence, it's natural to wonder whether the two are connected. 

Hemorrhoids don't directly produce gas or bloating, but there's a real physiological link worth understanding.

This article explains the actual relationship between hemorrhoids, gas, and bloating, what's happening in your body, and when these symptoms might point to something else entirely.

Hemorrhoids themselves don't cause bloating, and they're not a direct source of intestinal gas. However, hemorrhoids can affect how well you control passing gas, and they often share the same underlying causes as bloating — like constipation, straining, and diet — which is likely why people notice the two together.

The Real Connection: Hemorrhoids and Gas Control

Hemorrhoidal Tissue Plays a Role in Continence

Hemorrhoids, or "anal cushions," are a normal part of anatomy — vascular tissue that everyone has around the anal canal. Research published in the World Journal of Gastroenterology explains that these cushions help seal the anal canal and are estimated to contribute roughly 15–20% of resting anal canal pressure, working alongside the anal sphincter muscles to maintain continence. Part of their job is helping the body distinguish between stool, liquid, and gas before deciding whether to release it.

Enlarged Hemorrhoids Can Disrupt That Function

When hemorrhoidal tissue becomes enlarged, displaced, or damaged, this fine-tuned continence mechanism can be affected. Medical literature notes that continence disturbances — including difficulty controlling gas — co-exist in a notable percentage of people with hemorrhoids, since the swollen or prolapsed tissue can't seal the anal canal as effectively as healthy tissue does.

This Is Different From Bloating

It's worth being clear that this relates to controlling the release of gas (sometimes felt as increased flatulence or minor leakage), not to the actual production of gas in your gut. Bloating and excess gas originate higher up in the digestive system — from swallowed air, food digestion, and gut bacteria — which is a separate process from anything happening in the rectum or anus.

Why Gas, Bloating, and Hemorrhoids Often Show Up Together

Shared Cause: Constipation

Constipation is one of the most common contributors to both hemorrhoids and bloating. Hard, slow-moving stool increases straining (a major hemorrhoid trigger) while also allowing more time for gas to build up in the intestines, contributing to bloating and discomfort.

Shared Cause: Diet

A low-fiber diet, or a diet high in gas-producing foods (like beans, cruciferous vegetables, or carbonated drinks), can contribute to both bloating and constipation-related straining, indirectly worsening hemorrhoids at the same time.

Shared Cause: Straining and Holding In Gas

Some people who develop hemorrhoids also start holding in gas out of discomfort or self-consciousness, especially if hemorrhoids have made flatulence feel less controlled. Holding in gas can itself contribute to a bloated, uncomfortable feeling.

Underlying Digestive Conditions

Conditions like irritable bowel syndrome (IBS) commonly cause both bloating and altered bowel habits (constipation or diarrhea), and those altered bowel habits are, in turn, a well-established hemorrhoid risk factor. In these cases, gas, bloating, and hemorrhoids may all stem from the same underlying digestive issue rather than one directly causing the other.

When Gas or Bloating Might Signal Something Beyond Hemorrhoids

While mild gas and bloating are common and often harmless, it's worth paying attention if you notice:

• Bloating that's severe, persistent, or worsening over time
• Unexplained weight loss alongside digestive symptoms
• Gas or bloating paired with significant changes in bowel habits
• Difficulty controlling gas that feels new or is getting worse, which could indicate a continence issue worth evaluating
• Blood in the stool, which should always be checked regardless of other symptoms

These symptoms don't necessarily mean something serious, but they're a good reason to check in with a healthcare provider rather than assuming it's "just hemorrhoids."
