Common causes: Constipation allowing fecal matter to accumulate and infect the bowel wall; Low-fiber diet and wrong food combinations; Sugar and refined carbohydrates — feed toxic bacteria.

First thing to try: High-fiberThe part of plant foods your body can't fully break down — it keeps digestion moving. More → foods and lots of water — but for the first few days, eat wet, soupy porridge (boiled grains with plenty of water); add fiber foods back after diarrhea eases

🌿 Overview

Colitis is a chronic infection of the lower bowel. The mucous membrane wall becomes irritated from accumulated fecal matter (constipation). In ulcerative colitis, the colon wall ulcerates and bleeds. Over-the-counter laxatives, cooking in aluminum utensils, excess refined carbohydrates, sugar, food allergies, antibiotics, and emotional stress are all contributing causes. Low-fiberThe part of plant foods your body can't fully break down — it keeps digestion moving. More → diets, wrong food combinations, and poor bowel habits work together to create the condition. The single most important factor is diet.

Common signs

  • Bloody diarrhea and bloody mucus in the stools
  • Cramping pain and bloating
  • Incomplete elimination; straining at stool
  • Weakness and weight loss
  • Indigestion and headaches
  • Sometimes hard stools alternate with diarrhea
  • Diverticula (pockets in the colon wall) may develop

🔎 Why it happens

Common causes and triggers — spotting yours is often the first step to relief.

  • Constipation allowing fecal matter to accumulate and infect the bowel wall
  • Low-fiber diet and wrong food combinations
  • Sugar and refined carbohydrates — feed toxic bacteria
  • Food allergies — over-the-counter laxatives, aluminum cookware
  • Antibiotics destroying beneficial intestinal flora
  • Nervous tension and emotional stress — intensify the condition
  • Toxic megacolon (rare): intestinal wall weakens, balloons out, could rupture

✅ What to do

Gentle, practical steps you can take at home — start at the top.

  1. High-fiberThe part of plant foods your body can't fully break down — it keeps digestion moving. More → foods and lots of water — but for the first few days, eat wet, soupy porridge (boiled grains with plenty of water); add fiber foods back after diarrhea eases
  2. Do NOT start with raw greens, carrots, or peanuts; begin with cooked/steamed leafy vegetables, cooked potatoes, oat bran, brown rice, millet, sweet potatoes, bananas, cooked carrots, squash, and avocados
  3. Drink fresh, raw cabbage, carrot, celery, and parsley juice — actively heals the colon
  4. 8 oz. freshly prepared cabbage juice immediately before each meal
  5. Activated charcoal: heaping tsp. with each loose stool — very effective
  6. Slippery elm: 1 tsp. powdered slippery elm in 1 pint boiling water, blend, add flavor, drink slowly
  7. Peppermint, catnip, goldenseal, and alfalfa are also helpful
  8. Teas for drinking: cayenne, comfrey, marshmallow root, mullein leaves, slippery elm
  9. Pectin (apple pectin): reduces colitis inflammationThe body's natural response to injury — like redness, swelling, or heat around a sore spot. More →
  10. Hot fomentations to the abdomen for 20 minutes once daily
  11. Distilled water: colitis is frequently reduced by drinking distilled water

🍽️ Eating to help

Food is one of the gentlest medicines — small, steady changes help most.

Favor these

  • High-fiber whole plant foods (after acute phase)
  • Cabbage juice (8 oz. before each meal)
  • Brown rice, oat bran, millet, lentils, rice cakes
  • Cooked vegetables initially; add raw later
  • Slippery elm tea

Go easy on

  • Dairy products (irritate the colon)
  • Wheat products (may also trigger)
  • Carbonated beverages, iced drinks, very hot foods
  • High-fat foods and oils (worsen diarrhea)
  • Yeast products (common trigger)
  • Competitive sports and stress (cause tension that worsens it)

Keep a daily food diary — some patients are sensitive only to specific foods (yeast, wheat, dairy). The key is identifying personal triggers. Eat slowly, chew thoroughly — undigested food in the colon is a direct cause.

⚖️ Good to know

  • Toxic megacolon is a medical emergency — the colon wall weakens and may rupture
  • Bloody diarrhea that is severe or worsening requires urgent medical evaluation
  • Aluminum cookware contributes to colitis — stop using it

🩺 When to see a doctor

  • For colonoscopy to confirm diagnosis and rule out colorectal cancer.
  • Immediately if bleeding is heavy, if fever is high, or if abdomen becomes rigid.
