Colon Inflammation – Symptoms, Therapy, Diet

The term 'colitis' refers to intricate functional and structural abnormalities within the large intestine that necessitate thorough examination to accurately determine the nature of the inflammatory process. Clinical practice may encounter diverse types of inflammation, depending on their underlying causes. These may include: infectious colitis - triggered by pathogenic microorganisms such as rotaviruses, Escherichia coli (responsible for traveler's diarrhea), or Salmonella and Shigella bacteria. Occasionally, pseudomembranous colitis may also occur, resulting from Clostridium difficile bacterial infection. Inflammatory bowel conditions of infectious origin often include those caused by Candida albicans yeasts, leading to systemic fungal infections; toxic colitis - arising as a mucosal response to exposure to toxic agents such as botulinum toxin, poisons, medications, toxins, or pesticides. This may occur, for instance, after consuming poisonous mushrooms or spoiled canned foods; non-specific inflammatory bowel diseases (IBD) - a category of disorders including Crohn's disease and ulcerative colitis (also known as colitis ulcerosa), which have an autoimmune basis. These are chronic conditions characterized by alternating periods of exacerbation and remission. Colitis can also be classified based on anatomical location (small or large intestine), duration and symptom presentation (acute or chronic), and etiology - infectious, toxic, or non-specific.

The manifestations of large intestine inflammatory conditions can vary depending on the type and origin of the inflammation. Infectious and toxic conditions present with a sudden and acute onset – symptoms develop and intensify within a short timeframe (typically within 48 hours) of exposure to a triggering agent, such as toxins or bacterial presence. In these cases, clinical features include disrupted bowel function with a tendency toward diarrhea – often mucous or bloody, severe abdominal pain, nausea, vomiting, fever, and general fatigue. Potential complications encompass electrolyte imbalances and dehydration. Generally, symptoms resolve following diagnosis, elimination of the causative factor, and initiation of treatment, without recurrence. In inflammatory bowel diseases, the clinical presentation differs – the condition follows a chronic course with alternating phases of remission and exacerbation. Additionally, diagnosis is more intricate – symptoms provide only preliminary indications, requiring confirmation through endoscopic procedures (e.g., colonoscopy), during which mucosal biopsies are obtained for histopathological evaluation. This allows for the identification of ulcers or inflammatory changes in the intestine. Although both Crohn's disease and ulcerative colitis are autoimmune disorders where the immune system targets the body's own tissues, their clinical courses exhibit subtle differences.

For toxic and infectious forms of colitis, it is essential to eliminate the causative factors such as toxins or bacteria. Depending on the cause, appropriate pharmacological measures are taken, including antibiotics for bacterial infections or hospital treatment for poisoning. However, the treatment of non-infectious colitis is far more complex and requires long-term pharmacotherapy, including anti-inflammatory drugs, corticosteroids, immunosuppressants, and biological therapies. Diet also plays a crucial role in extending remission periods.

For acute and toxic intestinal infections, a low-fiber and easily digestible diet is recommended until inflammatory symptoms subside. Preventing dehydration and maintaining electrolyte balance is crucial, as frequent diarrhea and vomiting can lead to imbalances. Once symptoms improve, a gradual return to a balanced diet is advised. In chronic intestinal inflammation, diet is a key part of treatment and must be maintained lifelong. It should exclude inflammatory triggers like dairy, gluten, yeast, legumes, cruciferous vegetables, and nuts. The diet should be rich in vitamins (especially B12, folic acid, and D), maintain a 4:1 omega-6 to omega-3 fatty acid ratio, and limit fiber, particularly insoluble fiber, which can irritate the intestinal lining. Unprocessed, steam-cooked or boiled foods are preferred. Flaxseed infusions, aloe vera juice, or rosehip juice may be beneficial for soothing the intestinal mucosa.
