Crohn’s disease

Crohn’s Disease: An Overview

Introduction

Crohn’s disease is a chronic inflammatory condition of the gastrointestinal tract, part of a group of conditions known as inflammatory bowel diseases (IBD). It was first described in 1932 by Dr. Burrill B. Crohn and his colleagues.

Disease Characteristics

Affected Areas: It can affect any part of the gastrointestinal tract, from the mouth to the anus, but primarily targets the end of the small bowel (ileum) and the beginning of the colon.
Inflammation and Irritation: The disease causes inflammation and irritation, mainly in the small intestine and the beginning of the large intestine. The inflammation often spreads into the deeper layers of the bowel.

Symptoms

Crohn’s disease symptoms vary but commonly include:

Abdominal pain and severe diarrhea
Fatigue, weight loss, and malnutrition
Additional symptoms: Rectal bleeding, fever, nausea, vomiting, and generalized fatigability

Etiology

The exact cause is unknown, but it likely involves a combination of factors:

Genetic, microbial, immunologic, environmental, dietary, vascular, and psychosocial components
Risk factors include family history, smoking, and certain medications (antibiotics, birth-control pills, NSAIDs).

Treatment and Quality of Life

Lifelong Condition: No cure, but treatments aim to manage symptoms and prevent complications.
Treatment Approaches: Medications, bowel rest, and surgery.
Complications and Quality of Life: Despite treatment, many patients face a poor quality of life, with risks of intestinal obstruction, fistulas, abscesses, anal fissures, ulcers, malnutrition, and inflammation in other body areas.

Epidemiology

Prevalence: Affects nearly 1 in 100 Americans.
Demographics: Affects both men and women equally, most commonly diagnosed between ages 20 and 30, prevalent in all ethnic backgrounds, with recent increases in Hispanics and Asians.
