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.
Diarrhea is frequent, runny bowel movements (poop). Most kids battle diarrhea from time to time. The good news is that it usually doesn't last long and is more annoying than dangerous. Still, it's important to know how to relieve and even prevent diarrhea.
What Causes Diarrhea?
Diarrhea is usually caused by gastrointestinal (GI) infections caused by germs (viruses, bacteria, or parasites). A diet high in sugar (for instance, from drinking lots of juice) also can bring on diarrhea.
Viral gastroenteritis (often called the "stomach flu") is a common cause of diarrhea and, often, nausea and vomiting. It can spread through a household, school, or childcare center quickly. The symptoms usually last just a few days, but kids (especially babies) who can't get enough fluids can become dehydrated.
Rotavirus infection, a frequent cause of diarrhea in kids, can bring on explosive, watery diarrhea. Outbreaks are more common in the winter and early spring months, especially in childcare centers. A very effective rotavirus vaccine is now recommended for infants.
Enteroviruses, particularly coxsackievirus, also can cause diarrhea in kids, especially during the summer months.
Kids with viral gastroenteritis often develop a fever and vomiting first, followed by diarrhea.
How Is Diarrhea Treated?
Mild diarrhea usually isn't cause for concern if your child is acting normally and drinking and eating enough. It usually passes in a few days, and kids recover with home care, rest, and plenty of fluids (but avoid sugary juice drinks).
Kids who aren't dehydrated or vomiting can continue eating and drinking as usual. In fact, continuing a regular diet may even shorten the diarrhea episode. You may want to serve smaller portions of food until the diarrhea ends.
Do not give your child an over-the-counter anti-diarrhea medicine unless your doctor gives the OK.
The goal when treating diarrhea is to replace the lost fluids and electrolytes (salts and minerals). For kids who aren't dehydrated, doctors recommend:
Continuing with a regular diet and giving more liquids to replace those lost while the diarrhea continues.
Offering additional breastmilk or formula to infants.
For kids who show signs of mild dehydration, doctors often recommend rehydration with an oral rehydration solution (ORS). These are available in most grocery stores and drugstores without a prescription and replace body fluids quickly. Your doctor will tell you what kind to give, how much, and for how long.
Kids should never be rehydrated with water alone because it doesn't contain the right mix of sodium, potassium, and other important minerals and nutrients.
In some cases, kids with severe diarrhea may need to get IV fluids at the hospital for a few hours to help combat dehydration.
Can Diarrhea Be Prevented?
It's almost impossible to prevent kids from ever getting diarrhea. But here are some ways to make it less likely:
Make sure kids wash their hands well and often, especially after using the toilet and before eating. Hand washing is the most effective way to prevent diarrheal infections that pass from person to person. Dirty hands carry germs into the body when kids bite their nails, suck their thumbs, eat with their fingers, or put any part of their hands into their mouths.
