Most hemorrhoids shrink on their own within one to two weeks with simple at-home measures: increasing fiber, soaking in warm water, and reducing strain during bowel movements. The key is lowering pressure on the swollen blood vessels in the anal canal so they can return to their normal size. For hemorrhoids that don’t respond to home care, office procedures can eliminate them with minimal downtime.
Why Hemorrhoids Swell in the First Place
Hemorrhoids are cushions of blood vessels that everyone has in the anal canal. They become a problem when the vessels lose their ability to regulate blood flow. Normally, a ring of smooth muscle cells around these vessels acts like a valve, controlling how much blood enters and ensuring it drains efficiently. When that mechanism breaks down, blood overfills the vessels, stretching and inflaming them. Straining on the toilet, sitting for long periods, pregnancy, and chronic constipation all increase pressure and push this process along.
Shrinking a hemorrhoid means reversing that cycle: reducing blood flow to the swollen tissue, easing inflammation, and letting the vessels tighten back up. Every effective treatment, from dietary changes to surgery, works on one or more of those mechanisms.
Fiber and Fluids: The Foundation
Soft, bulky stool is the single most important factor in letting hemorrhoids heal. Hard stool forces you to strain, which engorges the vessels all over again. The recommended daily fiber intake is about 14 grams per 1,000 calories you eat, so roughly 28 grams per day on a standard 2,000-calorie diet. Most people fall well short of that.
Good sources include beans, lentils, oats, whole-grain breads, broccoli, pears, and raspberries. If you can’t hit your target through food alone, a psyllium-based fiber supplement works well. Increase your intake gradually over a few days to avoid bloating. Drink plenty of water alongside the fiber, since fiber absorbs liquid to soften stool. Without adequate fluids, extra fiber can actually make constipation worse.
Sitz Baths and Topical Treatments
A sitz bath is a shallow soak of your anal area in warm water. The ideal temperature is around 104°F (40°C), warm enough to increase blood flow and relax the muscles without scalding. Soak for 15 to 20 minutes, two to three times a day, especially after bowel movements. You can use a small plastic basin that fits over your toilet seat or simply sit in a few inches of water in the bathtub. Pat the area dry gently afterward.
Witch hazel pads are one of the more effective over-the-counter options. The active compound, a type of tannin, works as an astringent: it causes surface proteins in the swollen tissue to tighten and contract, forming a protective layer that reduces oozing and irritation while new tissue heals underneath. You can apply witch hazel pads directly to the area several times a day.
Creams and ointments containing hydrocortisone or a numbing agent like lidocaine can reduce itching and pain. These are meant for short-term use, generally no more than one week. Prolonged hydrocortisone use thins the skin and can make things worse.
Habits That Speed Up Shrinkage
What you do on and off the toilet matters as much as what you apply to the hemorrhoid. A few changes can make a noticeable difference within days:
- Don’t linger on the toilet. Sitting there scrolling your phone keeps constant pressure on the anal vessels. Go when you feel the urge, and get up when you’re done.
- Don’t strain. If a bowel movement isn’t happening easily, get up and try again later. Bearing down is the most direct way to re-engorge hemorrhoidal tissue.
- Move throughout the day. Sitting or standing in one position for hours pools blood in the pelvic area. Short walks help circulation.
- Use a small footstool. Elevating your feet while sitting on the toilet straightens the anorectal angle, reducing the need to strain.
Oral Flavonoids
Flavonoid supplements (often sold as diosmin or micronized purified flavonoid fraction) are widely used in Europe and increasingly available elsewhere. They work by increasing the tone of vein walls, reducing the capacity of swollen vessels, decreasing the permeability of tiny capillaries so less fluid leaks into surrounding tissue, and improving lymphatic drainage. They also have anti-inflammatory effects. Several clinical trials have shown they reduce bleeding, pain, and itching more effectively than placebo. They’re typically taken for several weeks and are well tolerated.
What to Expect: Healing Timeline
A mild flare-up often improves within a few days of consistent home treatment, with full resolution in one to two weeks. Most prolapsed internal hemorrhoids (those that bulge out during a bowel movement but retract on their own) go away without any medical intervention. External hemorrhoids, especially thrombosed ones (where a blood clot forms under the skin), tend to be more painful and can take two to four weeks to fully resolve. The clot gradually reabsorbs as the tissue heals.
If your symptoms haven’t improved after one week of consistent at-home care, it’s worth following up with a doctor. Persistent or recurring hemorrhoids may need an office-based procedure.
Office Procedures for Stubborn Hemorrhoids
When home treatment isn’t enough, several minimally invasive procedures can shrink or eliminate hemorrhoids, usually performed in a doctor’s office without general anesthesia.
Rubber Band Ligation
This is the most common office procedure for internal hemorrhoids. A tiny rubber band is placed around the base of the hemorrhoid, cutting off its blood supply. The tissue dies and falls off within a few days, leaving a small scar that anchors the remaining tissue in place. You may feel pressure or mild discomfort for a day or two. Long-term studies show a cumulative success rate of about 80% when including retreatment for recurrences. Some people need a second or third session for recurring symptoms, with success rates of roughly 62% to 74% for each subsequent treatment.
Sclerotherapy
A chemical solution is injected directly into the hemorrhoid, causing it to scar and shrink. This is typically used for grade 1 and 2 hemorrhoids (small, mostly internal) and is especially useful for patients who take blood thinners or have other health conditions that make more invasive procedures risky. About 87% of patients report satisfaction with the treatment across clinical studies.
Infrared Coagulation
A device directs infrared light at the hemorrhoidal tissue, generating heat that coagulates blood vessels and evaporates water from the cells. The tissue shrinks as a result. It’s quick, causes less discomfort than banding, and works best for smaller internal hemorrhoids.
When Hemorrhoids Need Surgery
Large hemorrhoids, those that repeatedly prolapse or don’t respond to office procedures, may require surgical removal. A hemorrhoidectomy removes the tissue entirely and has the lowest recurrence rate of any treatment, but it involves a longer and more uncomfortable recovery, often two to four weeks. Stapled hemorrhoidopexy is a less painful alternative that lifts prolapsed tissue back into place and interrupts its blood supply. Another option, Doppler-guided hemorrhoidal artery ligation, uses ultrasound to locate and stitch closed the arteries feeding the hemorrhoid, starving it of blood flow.
These surgical approaches are reserved for severe or recurrent cases and are performed under anesthesia in an operating room.
Signs That Need Prompt Attention
Rectal bleeding is common with hemorrhoids, but certain symptoms point to something more serious. Seek care if you experience heavy rectal bleeding that doesn’t stop, fever and chills, severe pain that worsens rather than improves, nausea and vomiting alongside rectal symptoms, or persistent changes in bowel habits. These can indicate a complication like a badly thrombosed hemorrhoid, an abscess, or a condition unrelated to hemorrhoids that needs its own evaluation.
