What Are the Signs and Symptoms of IBS in Infants?

Irritable bowel syndrome, or IBS, is a gastrointestinal disorder that causes abdominal discomfort. It is classified as a functional disorder because it does not cause damage to the bowel, is not life-threatening and does not lead to other diseases, according to the National Institute of Diabetes and Digestive and Kidney Diseases. The condition is common in people of all ages, including babies and children, but the cause remains unknown. Symptoms can vary widely from person to person.

Irregular Bowel Habits

• Irritable bowel syndrome can cause a change in regular bowel habits. For example, frequent diarrhea and constipation can be a sign of IBS in a baby. If your baby experiences diarrhea or constipation for more than a few days, he should be evaluated by a doctor because these are also symptoms of more serious bowel disorders such as Crohn's disease. Other bowel habits that may be caused by IBS include a feeling of urgency when having a bowel movement, the feeling that the bowels have not been emptied and straining during bowel movements. You may also notice mucous in your infant's stool, according to the National Institute of Diabetes and Digestive and Kidney Diseases.

Pain

• Another sign of irritable bowel syndrome is pain or discomfort in the abdominal region. Some babies may experience pain after eating, or it may come and go. In some cases, the pain can be relieved with a bowel movement, according to the University Hospitals. Babies cannot communicate pain effectively, so it may manifest itself as fussiness. You may notice your baby is more crabby, irritable and difficult to soothe.

Bloating

• Another common symptom of irritable bowel syndrome is abdominal bloating. The bloating can cause a feeling of fullness and the appearance that the abdomen is distended, according to University Hospitals. Babies can also have gas and may experience nausea and vomiting as a result of IBS.
