What are the reasons for abdominal pain in a two-year-old child

Patient's question:

Detailed medical condition and consultation purpose: Sometimes stomach pain at night
Duration and onset of the current illness: A week
Current general condition: Occurs sometimes
Previous diagnosis and treatment history and effectiveness: Pediatric gastroenteritis

Doctor's answer:

The child frequently experiences stomach pain without fever or diarrhea. The pain is usually localized around the navel. During the pain, the child may sweat coldly, have pale complexion, or even roll around clutching their stomach. However, the pain often subsides on its own after a short while, and the child's eating and playing return to normal. Nevertheless, similar abdominal pain can still occur on the same day or the next day. This is a common condition known as "intestinal cramps." Intestinal cramps are generally caused by allergic reactions to food or even cold, which lead to the excitation of nerves that control the intestinal wall.
