What Is Proctitis?

Proctitis means the inside lining of your rectum is swollen. It can cause pain, bleeding, and the sudden urge to go to the bathroom. If left untreated, it can worsen and affect your everyday life.

Common Causes and Risk Factors

  • Inflammatory bowel disease (IBD) such as ulcerative colitis
  • Infections from bacteria, viruses, or parasites
  • Radiation therapy to the pelvis
  • Sexually transmitted infections (STIs)
  • Frequent use of rectal medications like enemas or suppositories
  • Family history of IBD or other gut health issues

Signs and Symptoms

  • Pain or pressure in the rectum
  • Frequent or urgent need to have a bowel movement
  • Blood or mucus in the stool
  • Feeling of fullness or heaviness in the rectum
  • Diarrhea lasting more than a few days
  • Alcohol can trigger or worsen flare-ups

How Dr. Nghia Nguyen Diagnoses Proctitis?

Dr. Nguyen uses a step-by-step approach:

Medical History and Exam

He reviews your symptoms, bowel habits, family history of IBD, and any prior treatments.

Rectal Examination

A gentle digital exam checks for tenderness, swelling, and any structural issues.

Endoscopy

  • Flexible sigmoidoscopy or colonoscopy to directly visualize the rectal lining.
  • Biopsies taken, if needed, to distinguish between ulcerative proctitis and other conditions.

Stool Tests

Comprehensive stool analysis rules out bacterial, viral, or parasitic infections.

Imaging Studies (if needed)

Pelvic MRI or CT scan assesses deeper inflammation, strictures, or complications.

Frequently Asked Questions

What's the difference between ulcerative proctitis and ulcerative colitis?

Ulcerative proctitis is limited to inflammation of the rectum's lining. Ulcerative colitis involves a broader section or the entire colon, requiring different treatment approaches.

What is the ICD-10 code for ulcerative proctitis?

The ICD-10 code for ulcerative proctitis is K51.2. This code is used for accurate medical records, billing, and insurance claims.

Can alcohol make it worse?

Yes. Alcohol can irritate the rectal lining and trigger or worsen flare-ups, especially in patients with ulcerative proctitis.

How long until I feel better?

Many patients notice symptom relief within a few days of starting treatment. Complete healing and return to normal bowel habits can take several weeks.

What should I eat during a flare-up?

Stick to small, low-fiber, easy-to-digest meals and stay hydrated. Avoid spicy foods, caffeine, and alcohol, then gradually reintroduce fiber as inflammation subsides.

Is proctitis curable?

Proctitis is generally a chronic condition that can be well-managed but may recur. Ongoing care, medication, and lifestyle adjustments help prevent flare-ups.

What happens if I don't treat it?

Untreated proctitis can lead to rectal ulcers, strictures (narrowing), and increased risk of complications. Early evaluation and treatment prevent long-term damage.
