What is Inflammatory bowel disease (IBD)?

Inflammatory bowel disease (IBD) is a chronic non-specific intestinal inflammatory disease.

At present cause still is not clear, have bigger difference with common enteritis.

Inflammatory bowel disease (IBD) includes ulcerative colitis (UC) and crohn disease (CD).

IBD is a common disease in North America and Europe, but in recent years, the incidence of inflammatory bowel disease in China has gradually increased, especially in young people, which has become a common digestive system disease.

Ulcerative colitis most commonly occurs in young adults, with a peak age of 20-49 years.

There was no significant difference in prevalence between men and women.

The clinical manifestations are:

1. Persistent or recurrent diarrhea

2. Mucous pus blood stool with abdominal pain

3. Tenesthesia and different degrees of systemic symptoms, such as weight loss, fever, fatigue, anemia, etc

4. Extraenteral can be manifested in the skin and mucosa (such as oral ulcer, erythema nodosum, etc.), joints (peripheral arthritis, spinal arthritis, etc.), eyes (iritis and uveitis, etc.) and hepatobiliary (fatty liver, primary sclerosing cholangitis, etc.)

Mucous blood is the most common symptom of ulcerative colitis.

Crohn's disease most commonly develops in youth, with a peak age of 18 to 35 years.

The prevalence was slightly higher in men than in women.

The clinical manifestations are:

1. Digestive tract manifestations: diarrhea, abdominal pain, bloody stool.

2. Systemic manifestations: weight loss, fever, loss of appetite, fatigue, anemia, etc. Growth retardation is seen in adolescent patients.

3. Extraenteral can be manifested in the skin and mucosa (such as oral ulcer, erythema nodosum, etc.), joints (peripheral arthritis, spinal arthritis, etc.), eyes (iritis and uveitis, etc.) and hepatobiliary (fatty liver, primary sclerosing cholangitis, etc.)

The common complications were fistula, abdominal abscess, intestinal stenosis and intestinal obstruction, and perianal lesions.

Anal fistula is usually the first symptom in patients with Crohn's disease.

Inflammatory bowel disease is usually complicated, recurrent, prolonged, serious may be disabled or even life-threatening, known as "Deathless Cancer", "Green Cancer".
