Internal Hemorrhoids: Symptoms and Management

Typical Symptoms

Internal hemorrhoids characteristically present with painless, bright red rectal bleeding during defecation—blood appears on toilet paper or drips into the toilet bowl—and are classified into four grades based on the degree of prolapse. 1, 2

Primary Symptom Profile

  • Bleeding: Bright red blood that appears during or immediately after bowel movements, either on toilet paper, dripping into the toilet, or squirting into the bowl 1, 2
  • Prolapse: Tissue protrusion from the anus that varies by grade—Grade I hemorrhoids bleed without prolapsing, Grade II prolapse with spontaneous reduction, Grade III require manual reduction, and Grade IV are irreducibly prolapsed 1, 3
  • Mucus discharge and perianal irritation: Prolapsed internal hemorrhoidal tissue deposits mucus onto perianal skin, causing chemical irritation, itching, and visible erythema 4
  • Discomfort during defecation: A sensation of fullness or pressure, though severe anal pain is not typical of uncomplicated internal hemorrhoids and suggests alternative pathology such as anal fissure (present in up to 20% of hemorrhoid patients), thrombosis, or abscess 1, 2

Critical Diagnostic Pitfall

Never attribute rectal bleeding to hemorrhoids without proper evaluation—hemorrhoids alone do not cause positive fecal occult blood tests or anemia (which occurs in only 0.5 per 100,000 population with hemorrhoidal disease). 1, 2 All patients with rectal bleeding require at minimum sigmoidoscopy, and complete colonoscopy is indicated when bleeding is atypical, anemia is present, or colorectal cancer risk factors exist 2.

Management Algorithm

First-Line Conservative Management (All Grades)

All internal hemorrhoids should initially be managed with dietary and lifestyle modifications, regardless of grade. 1, 3

Dietary Modifications

  • Fiber supplementation: Increase dietary fiber to 25-30 grams daily, achievable with 5-6 teaspoonfuls of psyllium husk mixed with 600 mL water daily 1
  • Adequate hydration: Increase water intake to soften stool and reduce straining 1
  • Avoid prolonged straining: This is the most critical behavioral modification to prevent symptom progression 1

Pharmacological Adjuncts

  • Flavonoids (phlebotonics): Relieve bleeding, pain, and swelling by improving venous tone, though 80% of patients experience symptom recurrence within 3-6 months after cessation 1, 3
  • Topical treatments for symptom relief:
    • Topical analgesics (lidocaine 1.5-2%) for local pain and itching 1
    • Short-term topical corticosteroids (≤7 days maximum) for perianal inflammation—never exceed 7 days due to risk of perianal tissue thinning 1, 4

Office-Based Procedures (Grades I-III After Conservative Failure)

Rubber band ligation is the most effective office-based procedure and should be the first procedural intervention for persistent Grade I-III internal hemorrhoids, with success rates of 70.5-89%. 1, 3

Rubber Band Ligation

  • Technique: Band is placed at least 2 cm proximal to the dentate line to avoid severe pain, causing tissue necrosis and scarring that fixes tissue to the rectal wall 1
  • Efficacy: More effective than sclerotherapy and requires fewer repeat treatments than infrared photocoagulation 1
  • Limitations: Up to 20% of patients require repeated banding 3
  • Complications: Pain (5-60%, typically minor), bleeding when eschar sloughs (1-2 weeks post-procedure), and rare necrotizing pelvic sepsis (especially in immunocompromised patients) 1

Alternative Office Procedures

  • Sclerotherapy: Suitable for Grade I-II hemorrhoids, using sclerosing agents to cause fibrosis; 70-85% short-term success but only one-third achieve long-term remission 1, 3
  • Infrared photocoagulation: 67-96% success for Grade I-II hemorrhoids, though requires more repeat treatments 1, 3
  • Bipolar diathermy: 88-100% success for bleeding control in Grade II hemorrhoids 1

Surgical Management (Grades III-IV or After Conservative/Office Procedure Failure)

Conventional excisional hemorrhoidectomy is the most effective treatment overall, particularly for Grade III-IV hemorrhoids, with recurrence rates of only 2-10%. 1, 3

Indications for Hemorrhoidectomy

  • Failure of medical and office-based therapy 1
  • Symptomatic Grade III-IV hemorrhoids 1, 3
  • Mixed internal and external hemorrhoids 1
  • Concomitant anorectal conditions (fissure, fistula) requiring surgery 1
  • Anemia from hemorrhoidal bleeding 1

Surgical Techniques

  • Ferguson (closed) technique: Excision with primary wound closure, associated with reduced postoperative pain and improved wound healing 1
  • Milligan-Morgan (open) technique: Excision with wounds left open to heal by secondary intention 1
  • Both techniques have comparable efficacy with 90-98% success rates 1

Postoperative Expectations

  • Narcotic analgesics are generally required for pain management 1
  • Most patients do not return to work for 2-4 weeks 1
  • Complications include urinary retention (2-36%), bleeding (0.03-6%), anal stenosis (0-6%), infection (0.5-5.5%), and incontinence (2-12%) 1

Procedures to Avoid

  • Anal dilatation: Abandoned due to 52% incontinence rate at 17-year follow-up 1
  • Cryotherapy: Rarely used due to prolonged pain, foul-smelling discharge, and need for additional therapy 1

Special Clinical Scenarios

Hemorrhoids During Pregnancy

  • Occur in approximately 80% of pregnant persons, more commonly in the third trimester 1
  • Safe treatments include dietary fiber, adequate fluids, bulk-forming agents (psyllium husk), osmotic laxatives (polyethylene glycol or lactulose), and hydrocortisone foam in the third trimester 1

Hemorrhoids with Anemia

Hemorrhoidectomy is indicated when anemia results from hemorrhoidal bleeding, as this represents substantial chronic blood loss requiring definitive control. 1 However, colonoscopy must be performed first to exclude proximal colonic pathology before attributing anemia to hemorrhoids 1.

When to Reassess or Escalate Care

  • If symptoms worsen or fail to improve within 1-2 weeks of conservative treatment 1
  • If significant bleeding, severe pain, or fever develop 1
  • If anemia or hemodynamic instability occur 1

Common Pitfalls to Avoid

  1. Never assume all anorectal symptoms are from hemorrhoids—other conditions like anal fissures, abscesses, fistulas, inflammatory bowel disease, or colorectal cancer may coexist or be the primary cause 1, 2
  2. Do not skip endoscopic evaluation in patients with rectal bleeding, even when hemorrhoids are visible on examination 2
  3. Avoid prolonged topical corticosteroid use beyond 7 days, which causes perianal skin atrophy and increased vulnerability to injury 1, 4
  4. Do not perform rubber band ligation below the dentate line—this causes severe pain due to somatic sensory innervation 1
  5. Never delay definitive treatment when active bleeding has caused anemia, as the natural history is continued blood loss 1
