In case of functional constipation, considering that children are still in the growth and development stage, the causes of functional constipation are different, and the use of medication may cause some drug side effects. Therefore, it is recommended to first use dietary conditioning and adjust bowel habits for effective relief. If constipation has not been improved for a long time, or even if the child has obvious negative emotions, it is recommended to seek medical advice and use medication for relief: 1. Dietary conditioning: parents can increase the intake of high-fiber foods such as celery, potatoes, oats, sweet potatoes, rape, spinach, carrots and pumpkin for children to improve intestinal motility speed. At the same time, ensure that children drink enough water to increase the moistness of stool, promote the discharge of stool and relieve constipation symptoms; 2. Massage the abdomen: constipation is usually associated with slowed gastrointestinal tract dynamics, family members or children can walk along the intestinal tract and massage the abdomen clockwise to promote gastrointestinal peristalsis and relieve constipation symptoms; 3. Increase exercise: increase children’s daily activity in an appropriate amount to promote gastrointestinal peristalsis to improve constipation; 4. Adjust bowel habits: some children may not have formed good bowel habits, when there is an intention to defecate should be timely defecation. It is also beneficial to form the habit of regular defecation; 5. Medication: Children who still have not defecated for a long time through the above measures are recommended to seek medical attention. For example, wheat fiber, lactulose, and intestinal probiotics can be used, which are suitable for children because they are less irritating. In addition, if children’s constipation is caused by organic constipation, such as hypothyroidism, anal stenosis and other lesions, timely medical consultation is required for treatment of the original disease, and constipation will be relieved.
