Symptoms of FD usually begin during infancy and become worse with age. These symptoms can include:
Some children with FD may have repeated episodes of vomiting, called autonomic crises, which can occur every 15 to 20 minutes and can last for more than 24 hours. During these episodes, the child also may have very high blood pressure, a drenching sweat, skin blotches, pain in the abdomen, difficulty breathing and other symptoms. These episodes can be triggered by emotional or physical stress such as an infection.
