The incubation period of intussusception generally varies depending on the severity of the condition. Intussusception most commonly occurs during infancy or in adulthood. Typically, the incubation period is around 2 to 3 years of age, which is when the chances of developing intussusception are highest. In adults, intussusception is generally associated with tumors. As the tumor grows or other pathological changes occur, the likelihood of intussusception significantly increases. Therefore, once symptoms appear in patients with intussusception, it indicates a severe condition. Thus, in cases where intussusception is clearly diagnosed, timely surgical intervention should be administered to effectively treat the disease.
