Symptoms
The symptoms of IBS in children can vary, but they typically include abdominal pain, bloating, constipation, and diarrhea. Other symptoms may include gas, mucus in the stool, and a feeling of incomplete bowel movement. Children with IBS may also experience anxiety, depression, and fatigue. These symptoms can be debilitating and can affect a child's quality of life.
Causes
The exact cause of IBS in children is not known, but it is believed to be a combination of genetic, environmental, and psychological factors. Some researchers believe that IBS may be caused by a dysfunction in the muscles of the intestinal wall, which leads to abnormal contractions and changes in the movement of food through the intestines. Others believe that IBS may be caused by an overactive immune system or an imbalance of gut bacteria.
