1. What Are Hemorrhoids and Why Do They Occur?
Hemorrhoids, also known as piles, are naturally occurring clusters of veins located beneath the mucous membranes lining the lower rectum and anus. Hemorrhoidal disease arises when these veins become swollen and distended, resembling varicose veins in the legs. These swollen blood vessels struggle against gravity to return blood to the heart, which may explain why humans get hemorrhoids.
1.1. Internal vs. External Hemorrhoids: What’s the Difference?
There are two main types of hemorrhoids:
-
Internal hemorrhoids: These develop in the lower rectum and are typically painless, even when bleeding occurs. You might notice bright red blood on toilet paper or in the toilet bowl. Internal hemorrhoids can also prolapse, or extend beyond the anus, leading to irritation and itching.
-
External hemorrhoids: These form under the skin around the anus and are generally more uncomfortable. The skin covering them can become irritated and erode. A blood clot inside an external hemorrhoid can cause sudden, severe pain. You might feel or see a lump around the anus, which can leave excess skin (a skin tag) that may itch or become irritated.
2. What Causes Hemorrhoids to Develop? Unveiling the Root Causes
Several factors contribute to the development of hemorrhoids. Understanding these causes can help you take preventive measures and manage the condition effectively.
2.1. Chronic Constipation and Straining:
Historically, hemorrhoids have been linked to chronic constipation, straining during bowel movements, and prolonged sitting on the toilet. These actions disrupt blood flow to and from the rectal area, causing blood to pool and enlarge the veins.
2.2. Pregnancy and Increased Pressure:
Pregnancy is another common cause of hemorrhoids. As the uterus expands, it presses on the veins in the rectum and anus, increasing pressure and leading to swelling.
2.3. High Resting Anal Canal Tone:
Recent research indicates that individuals with hemorrhoids often have a higher resting anal canal tone, meaning the smooth muscle of the anal canal is tighter than average. This increased tightness, combined with constipation, exacerbates the problem.
2.4. Weakening Connective Tissues:
As we age, the connective tissues that support hemorrhoids can weaken, causing them to bulge and prolapse. This age-related weakening contributes to the increased prevalence of hemorrhoids in older adults.
3. How Are Hemorrhoids Diagnosed? A Simple Examination
Diagnosing hemorrhoids typically involves a straightforward medical history and physical examination.
3.1. Physical Exam and Digital Rectal Exam:
External hemorrhoids are usually apparent, especially if a blood clot has formed. A clinician may perform a digital rectal exam to check for blood in the stool.
3.2. Anoscopy, Sigmoidoscopy, and Colonoscopy:
The anal canal may be examined with an anoscope, a short, illuminated plastic tube inserted into the rectum. If there is evidence of rectal bleeding or microscopic blood in the stool, flexible sigmoidoscopy or colonoscopy may be performed to rule out other causes of bleeding, such as colorectal polyps or cancer, particularly in individuals over 45.
4. How to Treat Hemorrhoids at Home?
For relief from hemorrhoid symptoms, simple home remedies can be highly effective.
4.1. Increase Fiber Intake:
Adding more fiber to your diet, whether through food, fiber supplements (like Metamucil, Citrucel, or FiberCon), or both, can soften stools and make them easier to pass, reducing pressure on hemorrhoids.
4.1.1. High-Fiber Foods and Their Benefits:
High-fiber foods include broccoli, beans, wheat and oat bran, whole-grain foods, and fresh fruit. Fiber supplements can decrease hemorrhoidal bleeding, inflammation, and enlargement, as well as reduce irritation from trapped stool particles.
4.1.2. Gradual Increase and Fluid Intake:
To avoid bloating or gas, start slowly and gradually increase your fiber intake to 25–30 grams per day. Also, increase your fluid intake to help the fiber work effectively.
4.2. Regular Exercise:
Moderate aerobic exercise, such as brisk walking for 20–30 minutes a day, can stimulate bowel function.
4.3. Timely Bowel Movements:
When you feel the urge to defecate, go to the bathroom immediately. Delaying can lead to increased pressure and straining.
4.4. Scheduled Toilet Time:
Schedule a set time each day, such as after a meal, to sit on the toilet for a few minutes. This can help establish a regular bowel habit.
4.5. Sitz Baths for Relief:
A sitz bath, which involves sitting in a few inches of warm water, can relieve itching, irritation, and spasms of the sphincter muscle.
4.5.1. How to Take a Sitz Bath:
Pharmacies sell small plastic tubs that fit over a toilet seat, or you can use a regular bathtub. Experts recommend a 20-minute sitz bath after each bowel movement and two or three times a day.
4.5.2. Gentle Drying:
Gently pat the anal area dry after the bath; avoid rubbing or wiping hard. A hair dryer can also be used to dry the area.
4.6. Topical Relief with Creams and Wipes:
Over-the-counter hemorrhoid creams containing a local anesthetic can temporarily soothe pain. Witch hazel wipes (Tucks) are also soothing and have no harmful effects.
4.7. Ice Packs for Swelling:
Applying a small ice pack to the anal area for a few minutes can reduce pain and swelling.
4.8. Cushions for Comfort:
Sitting on a cushion rather than a hard surface can reduce swelling of existing hemorrhoids and prevent new ones from forming.
4.9. Treating Blood Clots:
If an external hemorrhoid forms a blood clot, pain can be severe. If the pain is tolerable and the clot has been present for more than two days, use home treatments while waiting for it to resolve. More recent clots can be surgically removed or drained in a minor office procedure performed by a surgeon.
5. What Are the Minimally Invasive Procedures for Hemorrhoids Treatment?
When conservative treatments aren’t enough, minimally invasive procedures can offer relief.
5.1. Rubber Band Ligation:
Rubber band ligation is the most common hemorrhoid treatment in the United States. A small elastic band is placed around the base of the hemorrhoid, causing it to shrink. The surrounding tissue scars as it heals, holding the hemorrhoid in place.
5.1.1. Procedure and Complications:
It usually takes two to four procedures, done six to eight weeks apart, to eliminate the hemorrhoid completely. Complications are rare but can include mild pain, bleeding, and infection.
5.2. Other Office Procedures:
Other office procedures include laser or infrared coagulation, sclerotherapy, and cryosurgery. These work on the same principle as rubber band ligation but may not be as effective in preventing recurrence.
6. What Are the Surgical Options for Hemorrhoids Treatment?
If other treatments fail, surgery may be necessary.
6.1. Hemorrhoidectomy:
Hemorrhoidectomy involves making a narrow incision around both external and internal hemorrhoid tissue and removing the affected blood vessels. This procedure cures 95% of cases and has a low complication rate. It requires general anesthesia, but patients can usually go home the same day and return to work after 7–10 days.
6.2. Stapled Hemorrhoidopexy:
Stapled hemorrhoidopexy is an alternative to traditional hemorrhoidectomy. It treats bleeding or prolapsed internal hemorrhoids by using a stapling device to anchor the hemorrhoids in their normal position. Like traditional removal, this procedure is performed under general anesthesia as day surgery.
