Inflammatory Bowel Disease in Children

About Inflammatory Bowel Disease

Inflammatory bowel disease refers to two chronic (or recurring) conditions called “Crohn’s disease” and “ulcerative colitis,” which cause redness and swelling (inflammation) in parts of the intestinal tract. Like asthma, IBD symptoms in children occur in bouts — periodically flaring up for sometimes weeks or months.

 
What’s the Difference Between IBS and IBD?

Often confused with irritable bowel syndrome (IBS), IBD is a condition that can cause the intestines to narrow and restrict food from moving through the bowel. IBS is a functional disorder, which means the digestive system looks perfectly normal, but it doesn’t work exactly like it should. IBD and IBS have many similar symptoms, but IBS doesn’t cause blood in the stool (bowel movements or poop) like IBD can.

 
Crohn’s vs. Ulcerative Colitis in Children

Crohn’s disease and ulcerative colitis are both inflammatory bowel diseases that cause inflammation to different parts of the digestive system. Crohn’s can occur anywhere along the intestinal tract, but it’s commonly found in the last segment of the small intestine (ileum) and the large intestine (colon). Ulcerative colitis mostly affects the colon.

Crohn’s impacts the entire thickness of the intestine and can affect more than one section of the intestinal tract. In contrast, ulcerative colitis occurs only within the inner lining of the organ and is found only in one spot.

 
What Causes IBD in Children?

The exact cause of IBD in children is unknown. However, experts agree that the environment, genetics, and/or diet may have something to do with it. Scientists believe that an overactive immune system may trigger inflammation in response to an offending agent, like a virus or certain foods. Researchers are actively studying IBD to get to the bottom of possible causes, and hopefully help relieve IBD symptoms in children and adults.

A to Z: Gastroenteritis

A to Z: Gastroenteritis

May also be called: Stomach Flu

Gastroenteritis is an infection that causes vomiting and diarrhea.

More to Know

Gastroenteritis can be due to an infection with a virus, bacteria, or parasites. Also called the "stomach flu," it is contagious and spreads easily in childcare and schools. It often also causes fever.

Stool samples might be tested for bacteria or parasites if there is blood in the stool (poop). Antibiotics are usually not needed except for certain types of infections in young infants and in people with immune problems.

Keep in Mind

Gastroenteritis usually is not serious and generally lasts a few days. The greatest risk from gastroenteritis is dehydration, so it's most important to stay hydrated with plenty of fluids. Young kids are at the highest risk for dehydration.
