Ileitis – zapalenie jelita krętego choroby zapalne jelit

Ileitis is an inflammation of the ileum, the final section of the small intestine. The condition can have various causes — from infections and autoimmune diseases to chronic inflammatory bowel disorders. Symptoms are often nonspecific, which is why diagnosis usually requires detailed gastroenterological evaluation.

 

The ileum is the last part of the small intestine and is responsible for:

  • absorbing vitamin B12,
  • absorbing bile acids,
  • completing digestion and transporting nutrients.

Inflammation in this area can significantly affect the functioning of the entire digestive system.

Ileitis – Common Causes

Ileitis is not a single disease but rather a condition that may result from different disorders.

1. Crohn’s Disease

One of the most common causes of chronic ileitis is Crohn’s Disease. This autoimmune condition may lead to:

  • ulcers,
  • intestinal narrowing,
  • diarrhea and abdominal pain,
  • weight loss.


2. Bacterial and Viral Infections

Inflammation may be caused by:

  • Yersinia,
  • Salmonella,
  • Campylobacter,
  • intestinal viruses.

Symptoms usually appear suddenly and resemble food poisoning.

 

3. Food Intolerances and Inflammatory Reactions

In some patients, chronic inflammation may be linked to:

  • food intolerances,
  • Celiac Disease,
  • intestinal hypersensitivity.


4. Medications and Irritating Factors

Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) may damage the lining of the small intestine.

 

Symptoms of Ileitis

Symptoms depend on the cause and severity of the inflammation. The most common include:

  • pain in the lower right side of the abdomen,
  • diarrhea,
  • bloating,
  • nausea,
  • fever,
  • fatigue,
  • loss of appetite,
  • weight loss.

Chronic inflammation may also lead to vitamin deficiencies and anemia.

 

Diagnosing ileitis requires consultation with a gastroenterologist. The doctor may recommend:

  • blood tests,
  • stool tests,
  • colonoscopy with examination of the terminal ileum,
  • CT scan or MRI,
  • biopsy of the intestinal lining.

Determining the underlying cause is essential because treatment depends on it.

Treatment of Ileitis

Treatment is tailored individually to each patient.

Therapy may include:

  • antibiotics for bacterial infections,
  • anti-inflammatory medications,
  • corticosteroids,
  • biological therapy for Crohn’s disease,
  • a light and easily digestible diet,
  • vitamin and mineral supplementation.

In severe cases, surgery may be necessary.

 

 

During symptom flare-ups, doctors usually recommend:

  • light and easy-to-digest meals,
  • limiting fatty and fried foods,
  • avoiding alcohol,
  • reducing insoluble fiber intake,
  • maintaining proper hydration.

There is no universal diet for ileitis — nutrition should be adapted to the underlying condition and the patient’s tolerance.

 

 

Immediate medical attention is necessary if symptoms include:

  • severe abdominal pain,
  • blood in the stool,
  • chronic diarrhea,
  • high fever,
  • rapid weight loss,
  • signs of dehydration.

Early diagnosis helps prevent complications and allows for more effective treatment.

 

  • Ileitis, or inflammation of the ileum, can range from mild to chronic in severity. It most commonly presents with abdominal pain and diarrhea, but identifying the exact cause requires specialist evaluation. Proper treatment and dietary management can help control symptoms and improve quality of life.
