Yes, sitting on the toilet for extended periods does increase your risk of developing hemorrhoids. The open shape of a toilet seat lets gravity pull blood downward into the veins around your anus and rectum, and the longer you sit, the more pressure builds in those vessels. About 26% of adults worldwide have hemorrhoids, making them one of the most common anorectal conditions, and prolonged toilet time is a well-documented contributing factor.
Why the Toilet Seat Matters
The toilet seat is uniquely bad for your hemorrhoidal veins because of its shape. Unlike a chair, which supports your full weight across your thighs and buttocks, a toilet seat leaves the anal area unsupported and suspended over an open hole. Gravity pulls blood into the network of veins (called the hemorrhoidal plexus) that line the lower rectum and anus. The longer you sit, the more blood pools in these vessels, stretching their walls.
This is made worse by the sitting position itself, which creates what researchers describe as a “dependent loop” in hemorrhoidal circulation. Blood flows in but has a harder time flowing back out. Over time, repeated sessions of prolonged sitting can weaken the walls of these veins, causing them to swell permanently. That swelling is a hemorrhoid.
Straining Adds to the Problem
Sitting too long often goes hand in hand with straining, which compounds the damage. When you bear down to push out a bowel movement, you take a deep breath and tighten your abdominal muscles. This dramatically raises the pressure inside your abdomen and chest, which in turn raises pressure in the veins around your rectum. It’s the same action doctors use to test heart function because it so reliably spikes blood pressure throughout the body.
During normal, healthy bowel movements, this pressure spike is brief. But if you’re constipated or forcing things, the sustained pressure engorges those already-vulnerable hemorrhoidal veins. Combine that with 10 or 15 minutes of gravity-assisted blood pooling from sitting on the toilet, and you have the two biggest mechanical causes of hemorrhoids working together.
Your Phone Is Part of the Problem
Smartphones have turned the bathroom into a reading room, and the data shows a real health consequence. In a study published in PLOS One, 66% of participants reported using their phones while on the toilet. Among those phone users, 37.3% spent more than five minutes per bathroom visit. For people who didn’t use phones, only 7.1% stayed that long.
The difference in hemorrhoid rates was striking. After adjusting for age, sex, BMI, exercise, straining habits, and fiber intake, smartphone use on the toilet was associated with a 46% increased risk of hemorrhoids. The most common phone activities were reading the news and scrolling social media. The phone itself doesn’t cause hemorrhoids. It just keeps you sitting there far longer than your body needs.
How Long You Should Actually Spend
Gastroenterologists at the Cleveland Clinic put it simply: five minutes should be the maximum time you spend on the toilet. If nothing is happening after a few minutes, get up and try again later. Sitting and waiting, or sitting and scrolling, only adds pressure to veins that don’t need it.
This doesn’t mean you need to rush. Most healthy bowel movements take between one and three minutes once things get moving. If you consistently need longer than five minutes, that’s a signal something else is going on, usually constipation or insufficient fiber, rather than a reason to sit and push harder.
What Hemorrhoids Actually Feel Like
Hemorrhoids progress through four stages, and catching them early makes a significant difference. Grade I hemorrhoids are entirely internal. They bulge into the anal canal but don’t come out, and you might only notice them as painless bleeding (bright red blood on toilet paper or in the bowl). Grade II hemorrhoids push out during a bowel movement but slide back in on their own.
Grade III hemorrhoids prolapse and stay out until you physically push them back in. Grade IV hemorrhoids prolapse and can’t be pushed back at all. Pain, itching, and discomfort generally increase with each grade. Most people who develop hemorrhoids from prolonged toilet sitting start at grade I or II, where simple habit changes can prevent things from getting worse.
A Footstool Can Cut Your Time in Half
One of the most effective changes you can make is elevating your feet with a small footstool while you sit. When you sit on a standard toilet, the angle between your rectum and anal canal is roughly 80 to 90 degrees, creating a kink that makes it harder to fully evacuate. Raising your knees closer to your chest opens that angle to 100 to 110 degrees, straightening the pathway and reducing the amount of straining needed.
The time difference is measurable. One study found that using a footstool cut average defecation time nearly in half, from about 113 seconds down to 56 seconds. Less time on the toilet and less straining means significantly less pressure on your hemorrhoidal veins. Leaning your upper body slightly forward while using a footstool increases the benefit further, particularly for older adults.
Fiber and Hydration Keep Things Moving
Most prolonged toilet sessions happen because stool is hard, dry, or difficult to pass. The single most effective dietary change for preventing this is increasing fiber. The current dietary guidelines recommend about 14 grams of fiber per 1,000 calories, which works out to roughly 28 grams per day on a standard 2,000-calorie diet. Most Americans get less than half that amount.
Fiber works by absorbing water and adding bulk to stool, making it softer and easier to pass without straining. Good sources include beans, lentils, whole grains, berries, and vegetables like broccoli and artichokes. Increase your intake gradually over a week or two to avoid gas and bloating. Pair higher fiber with adequate water, since fiber without fluid can actually make constipation worse. There’s no magic number for water intake, but if your urine is pale yellow, you’re generally well hydrated.
Other Habits That Reduce Your Risk
Beyond limiting toilet time and improving your diet, a few other practical changes lower the pressure on your hemorrhoidal veins. Regular physical activity keeps your digestive system moving and reduces the likelihood of constipation. Even a daily 20- to 30-minute walk makes a measurable difference in bowel regularity.
Avoid delaying bowel movements when you feel the urge. Waiting causes the colon to absorb more water from the stool, making it harder and more difficult to pass when you finally do sit down. And if you currently bring your phone into the bathroom, try leaving it outside the door for a week. For most people, that single change is enough to cut toilet time from 10 or 15 minutes down to under five.
