Children The first sign of intussusception in an otherwise healthy infant may be sudden, loud crying caused by belly pain. Infants who have belly pain may pull their knees to their chests when they cry. The pain of intussusception comes and goes, usually every 15 to 20 minutes at first. These painful episodes last longer and happen more often as time passes. Other symptoms of intussusception include:  Stool mixed with blood and mucus — sometimes referred to as currant jelly stool because of its appearance. Vomiting. A lump in the belly. Weakness or lack of energy. Diarrhea.  Not everyone has all of the symptoms. Some infants have no obvious pain. Some children don't pass blood or have a lump in the belly. And some older children have pain but no other symptoms. Adults Intussusception is rare in adults. Also, because symptoms of the disorder often overlap with the symptoms of other disorders, it's more challenging to identify. The most common symptom is belly pain that comes and goes. Nausea and vomiting also may occur. People sometimes have symptoms for weeks before seeking medical attention.
