Small Intestine Disorders

The small intestine absorbs nutrients but faces disorders like Crohn's disease, celiac disease, and small intestinal bacterial overgrowth (SIBO). These conditions inflame or impair its lining, hindering digestion. Globally, inflammatory bowel diseases affect millions, often starting young.

Common Types

  • Crohn's Disease: Targets ileum, causing ulcers, strictures; symptoms include cramping, diarrhea.
  • Celiac Disease: Gluten triggers immune damage, blocking absorption.
  • SIBO: Excess bacteria ferment food, producing gas and malnutrition.
    Other issues: short bowel syndrome post-surgery, motility disorders.

Symptoms
Bloating, abdominal pain, chronic diarrhea, nausea, vomiting, and blood in stool signal trouble. Unintended weight loss, fatigue, and anemia arise from poor nutrient uptake. Severe cases risk dehydration or obstructions.

Management
Diagnosis uses endoscopy, imaging, or breath tests. Treatments include gluten-free diets for celiac, antibiotics for SIBO, anti-inflammatories for Crohn's, and nutrition support. Lifestyle changes like probiotics aid recovery; surgery fixes blockages. Early care prevents complications like osteoporosis.
