Most hemorrhoid flare-ups resolve on their own within a few days, but the key to reducing how often they happen lies in a handful of daily habits. Fiber, hydration, toilet posture, and how you manage acute symptoms all play a role. Here’s what actually works to keep flare-ups infrequent and mild.
Eat More Fiber Than You Think You Need
Fiber is the single most effective dietary tool for preventing hemorrhoid flare-ups because it softens stool and adds bulk, which means less straining on the toilet. The recommended daily intake is 25 grams for women and 38 grams for men under 50 (dropping to 21 and 30 grams, respectively, after age 50). Most American adults eat only 10 to 15 grams a day, roughly half of what they need.
Insoluble fiber, the kind found in whole grains, vegetables, and wheat bran, is especially useful. It holds onto water as it moves through your digestive system, keeping stools soft and easy to pass. Soluble fiber (found in oats, beans, and fruits like apples and citrus) forms a gel-like consistency that also helps prevent hard, dry stools. You don’t need to obsess over which type you’re eating. A diet that includes a variety of fruits, vegetables, legumes, and whole grains will cover both.
If your current fiber intake is low, increase it gradually over one to two weeks. Adding too much too quickly can cause gas and bloating, which may make you avoid it altogether.
Pair Fiber With Enough Water
Fiber works best when it has water to absorb. In a clinical trial of patients with chronic constipation, everyone ate about 25 grams of fiber daily, but the group that also drank about 2 liters of water per day had significantly greater improvements in bowel frequency and needed fewer laxatives than the group drinking about half that amount. Fiber without adequate hydration can actually make constipation worse, since dry fiber creates harder stools.
Aim for around 1.5 to 2 liters of water daily. Coffee, tea, and other beverages count toward your total, though water is the simplest choice. If you notice your stools are still hard despite eating plenty of fiber, insufficient fluid is the most likely culprit.
Fix Your Toilet Habits
How you sit on the toilet matters more than most people realize. In a standard seated position, a muscle called the puborectalis creates a bend in the rectum that makes complete evacuation harder. When you raise your knees above your hips, that bend straightens out, and defecation requires significantly less effort.
A simple footstool placed in front of the toilet achieves this. In one study, using a footstool cut average defecation time nearly in half (about 56 seconds versus 113 seconds without one) and reduced self-reported straining from 2.5 to 1.4 on a standard scale. Leaning your upper body slightly forward while your feet are elevated improves the effect further.
Time on the toilet also matters. Sitting for prolonged periods puts continuous downward pressure on the hemorrhoidal cushions, weakening and stretching the tissue over time. Keep your bathroom visits short. If nothing is happening after a few minutes, get up and try again later. Leave your phone outside the bathroom if it tempts you to linger.
Stay Active, but Choose the Right Exercise
Regular moderate exercise helps prevent constipation by stimulating intestinal movement. Walking, swimming, and yoga are all good options that keep things moving without putting pressure on the anal area. Even 20 to 30 minutes of brisk walking most days can make a noticeable difference in bowel regularity.
Some exercises, however, increase intra-abdominal pressure and can trigger or worsen flare-ups. Activities to be cautious with include:
- Heavy weightlifting, especially squats and deadlifts performed with breath-holding (the Valsalva maneuver)
- Sit-ups and crunches, which compress the abdominal cavity
- Cycling, which puts direct pressure on the perineal area
- Rowing and horseback riding, which combine core pressure with repetitive friction
If you lift weights regularly, exhaling during the exertion phase (rather than holding your breath) can reduce the pressure spike. Lighter weights with more repetitions are gentler than maximal lifts.
Manage Acute Flare-Ups at Home
When a flare-up does happen, most symptoms, including swelling, irritation, and mild discomfort, will clear up within a few days. A thrombosed external hemorrhoid (one with a blood clot that feels like a firm, painful lump) typically takes days to a few weeks to resolve.
Sitz baths are one of the most reliable home treatments. Sit in a few inches of warm water for about 10 minutes, twice daily and after bowel movements. You can use a basin that fits over your toilet seat or simply use the bathtub. The warm water increases blood flow to the area and relaxes the surrounding muscles, which eases pain and promotes healing.
Over-the-counter creams serve two different purposes depending on their active ingredient. Products containing phenylephrine temporarily shrink swollen tissue and relieve itching for a few hours. Hydrocortisone creams reduce inflammation and pain more broadly. Hydrocortisone is better for persistent soreness and swelling, while phenylephrine-based products offer quicker but shorter-lived relief from itching and discomfort. Don’t use hydrocortisone products for more than about a week at a time, as prolonged use can thin the skin.
Avoid Straining in All Its Forms
Straining during bowel movements is the most direct trigger for flare-ups, but it’s not the only kind of straining that matters. Heavy lifting at work, chronic coughing, and even holding your breath during physical exertion all increase pressure in the veins around the rectum. If you have a persistent cough, treating the underlying cause helps protect against flare-ups. If your job involves heavy lifting, use proper technique: bend at the knees, keep the load close to your body, and breathe steadily throughout.
Constipation and diarrhea both contribute to flare-ups, though in different ways. Constipation forces you to strain; diarrhea irritates the anal lining with frequent, acidic stools. If either is a recurring problem for you, addressing the underlying cause (whether it’s diet, a medication side effect, or a digestive condition) will do more for hemorrhoid prevention than any topical treatment.
When a Flare-Up Needs Medical Attention
Small amounts of bright red blood on toilet paper after a bowel movement are common with hemorrhoids and not typically dangerous. But rectal bleeding that is heavy, persistent, or dark in color warrants a visit to your doctor, particularly if you’re over 45. Rectal bleeding can look identical whether it comes from a hemorrhoid or something more serious, including polyps or colorectal cancer, so it’s worth getting checked rather than assuming.
Seek prompt care if you experience rectal bleeding along with dizziness, rapid heartbeat, or vomiting blood. These signs suggest significant blood loss. Similarly, if a thrombosed hemorrhoid causes pain severe enough to interfere with daily activities or doesn’t improve after a week or two of home care, a doctor can offer procedures that provide faster relief.
