For a 4-year-old child who has not had a bowel movement for 5 days, constipation is often thought to be present, and treatment may include dietary adjustments, oral laxatives (e.g., Lactulose Oral Liquid), and, if necessary, the discretionary use of corkscrew to clear the bowels. For 4-year-old children usually daily regular stool, some children may be a little longer interval between defecation, such as every 2 ~ 3 days to relieve a stool, for 4-year-old children 5 days without stool, usually considered to exist constipation, some babies may appear abdominal discomfort, some may be difficult to defecate due to intestinal mucosal damage to the blood stool. Treatment should pay attention to adjust the daily diet, such as increasing dietary fiber and water intake, and develop the habit of regular defecation. Oral microecological agents (Clostridium casei) can be used to regulate the intestinal flora, or laxatives (e.g. lactulose oral solution) can be used to increase the water in the intestinal tract, so that the stools can be easily discharged. If necessary, use corkscrew to relieve the bowel movement, and be careful to use it gently. The above medications should be used under medical supervision, and active consultation with a specialist is recommended for evaluation and intervention.
