###Human: How can constipation be cured in a child? ###Assistant: Hi. This is due to severe constipation. We need to find the cause of constipation in this kid. Common causes are functional (irregular bowel habits), less common causes are urinary tract infections-anatomic abnormalities. Patients who have anatomical abnormalities, present in early childhood, we need to do barium studies to rule out anatomical abnormalities. As we know that functional constipation is the most common cause. We need to clear her bowel with an adequate dose of laxatives (acute clearing and maintenance dose of laxatives) and modify the lifestyle to regularize the bowel habits. Most of the patients respond with our regimen. If does not she may need further evaluation in form of colonic motility studies. I will not recommend any investigation straight away. I want to see previous routine reports if already done. To follow. Polyethylene glycol (130 gm), one packet in two liters water over four hours, monitor stool consistency, it should be clear water at the end, if it is not clear, repeat same again on same day. Most of the children require 3 to 4 packers in two days duration. No need to worry about loose stools, that will stop after stopping of medicine. By the second day give Polyethylene glycol (17 gm sachet), three sachets at night time. Do not push with force while defecation, pass stool twice in a day, sit for 15 minutes (preferably after food intake). Continue high fiber diet and plenty of water. Local anesthetic gelly (Lignocaine gel) to apply locally (perianal region, before defecation), if she had pain. We need to see her blood hemoglobin profile, urine routine examination. According to that we may need to do tTGA, IgA. Follow up with the response details and previous reports if done.
