Hemorrhoids

Hemorrhoids are swollen veins in the anus and lower rectum that can cause itching, pain, and bright red bleeding, most often from straining, constipation, or prolonged sitting.

Gastrointestinal
Hemorrhoids are swollen, enlarged veins in the lower rectum and anus, similar to varicose veins in the legs. They are extremely common — about half of adults over 50 have experienced them — and while they can be uncomfortable and worrisome, they are rarely dangerous and respond well to simple treatment in most cases. Causes: Hemorrhoids develop when pressure in the veins of the lower rectum increases. Contributing factors include:
  • Straining during bowel movements: The single most common cause, usually related to constipation and hard stools.
  • Chronic constipation or diarrhea: Both irritate and pressurize the anal veins; ongoing diarrhea can occur with conditions such as irritable bowel syndrome.
  • Prolonged sitting on the toilet: Long periods of sitting, including scrolling on a phone in the bathroom, allow the veins to swell.
  • Low-fiber diet: Leads to harder stools and more straining.
  • Pregnancy: The growing uterus and hormonal changes increase pressure on pelvic veins.
  • Heavy lifting and obesity: Both raise pressure inside the abdomen.
  • Aging: Supporting tissues in the rectum and anus naturally weaken over time.
Symptoms: Symptoms depend on whether the hemorrhoids are internal (inside the rectum) or external (under the skin around the anus):
  • Painless bright red bleeding: The hallmark of internal hemorrhoids — blood on the toilet paper, in the bowl, or coating the stool.
  • Prolapse: An internal hemorrhoid may bulge through the anus during a bowel movement and then recede or need to be pushed back.
  • Itching and irritation: Common around the anus, especially with external hemorrhoids.
  • Pain and swelling: A sudden, tender lump can form if blood clots inside an external hemorrhoid (a thrombosed hemorrhoid), which can be quite painful for several days.
  • Mucus and leakage: Prolapsed hemorrhoids can cause mucus discharge and make hygiene difficult, leading to further skin irritation.
Diagnosis: A doctor can usually diagnose hemorrhoids with a visual and digital rectal examination, sometimes using a small lighted scope (anoscope) to see internal hemorrhoids. Importantly, rectal bleeding should never simply be assumed to be hemorrhoids — depending on your age and risk factors, a colonoscopy may be recommended to rule out other causes of bleeding such as colon polyps or inflammatory conditions like ulcerative colitis. Chronic slow blood loss can occasionally cause iron-deficiency anemia, which is another reason persistent bleeding deserves a complete evaluation rather than reassurance alone. Treatment: Most hemorrhoids improve with conservative care:
  • Fiber and fluids: Softer, bulkier stools eliminate straining, which allows hemorrhoids to shrink and helps prevent new ones.
  • Fiber supplements and stool softeners: Psyllium or methylcellulose supplements, and a stool softener such as docusate when needed, keep stools soft while the area heals.
  • Good toilet habits: Avoid delaying the urge, limit time on the toilet, and do not strain.
  • Sitz baths: Soaking the area in warm water several times a day relieves irritation and spasm.
  • Topical treatments: Short courses of over-the-counter creams, ointments, or witch hazel pads can ease itching and discomfort.
  • Office procedures: Persistent internal hemorrhoids often respond to rubber band ligation, sclerotherapy, or infrared coagulation — quick outpatient procedures that cut off the hemorrhoid's blood supply.
  • Surgery: Reserved for large, prolapsing, or repeatedly thrombosed hemorrhoids that fail other measures.
When to Seek Care: See a doctor promptly for heavy or persistent rectal bleeding, bleeding with lightheadedness or weakness, severe pain, or a change in bowel habits. New rectal bleeding always deserves evaluation, even if you have had hemorrhoids before. Hemorrhoids are a common, fixable problem — there is no need to live with them or feel embarrassed about seeking help.
