Introduction
Hemorrhoids or piles are swollen veins in the lower rectum and anus that cause discomfort and bleeding. They occur due to increased pressure in the anal and rectal veins, leading to vein dilation and inflammation. Hemorrhoids are common, affecting millions worldwide, especially adults aged 45-65, though they can occur at any age.
Types
There are two main types:
- Internal Hemorrhoid: It develops inside the rectum and is usually painless but may bleed prolapse.
- External Hemorrhoid: It forms under the skin around the anus and can cause pain, swelling, and discomfort. Sometimes when thrombosed (clotted) it leads to intense pain and a hard lump.
Causes
These swollen anal/rectal veins arise due to chronically increased pressure in the lower rectum. Contributing factors include:
- Straining during bowel movements caused by constipation.
- Prolonged sitting (especially on the toilet).
- Pregnancy related increased pelvic pressure.
- Aging with weakened support tissues.
- Obesity and sedentary lifestyle.
- Low‑fiber diets.
- Lifting heavy objects.
- Less commonly, inflammatory bowel disease.
Signs & Symptoms
Symptoms vary greatly and may be asymptomatic. When present, the symptoms include:
- Bright red rectal bleeding during or after bowel movements.
- Itching, burning, irritation or discomfort around the anus.
- Pain or swelling, especially with external hemorrhoids.
- A bulge or prolapse from the anus in severe internal hemorrhoids.
Complications
Although often benign, complications can occur:
- Anemia: From chronic blood loss.
- Thrombosis: Painful, clot-filled hemorrhoid.
- Strangulation: Trapped prolapsed hemorrhoid, cutting off blood supply and causing severe pain.
Prevention
- Eating a high-fiber diet to prevent constipation.
- Drinking plenty of fluids to maintain soft stools.
- Exercising regularly to promote bowel regularity.
- Avoiding prolonged sitting, especially on toilets.
- Avoiding straining during bowel movements and heavy lifting.
Home Remedies
- Warm sitz baths several times a day to reduce pain and inflammation.
- Over-the-counter topical treatments like creams and suppositories.
- Keeping the anal area clean and dry.
- Increasing dietary fiber and fluid intake to ease bowel movements.
- Stool softeners/over‑the‑counter fiber help ease stool flow.
When to Seek Medical Attention
Medical consultation is advised if:
- Rectal bleeding occurs before, during, or after bowel movements to rule out more serious conditions like anal or colorectal cancer.
- Symptoms persist beyond one week despite home treatment.
- There is severe pain, swelling, or a prolapsed hemorrhoid that cannot be pushed back in.
- There is pus discharge, fever, or general unwell feeling indicating possible infection.
- Bleeding is heavy or continuous or if significant blood clots, severe pain, or new symptoms appear.
