Hi Doctor, My daughter 20 months(9 kg) and she is active active but she has been suffering from severe/chronic constipation for the past 2 months. We have been giving her Duphalac for the last 3–4 days, but there has been no noticeable improvement yet. We are also trying dietary changes: * Giving fibre-rich fruits like papaya and watermelon * Ensuring she drinks around 500 ml of water(including juice)daily Despite this, she is still having difficulty passing stools. Could you please advise: * What could be causing this prolonged constipation? * Whether the current treatment is sufficient or needs adjustment? * Any dietary or lifestyle changes we should follow? * Whether any tests or specialist consultation are needed? Thank you.
