### input:
my 18 months old son was diagnosed with congenital hypothyroidism 29 days after birth and has been on Thyronorm ever since. currently he takes 21 mcg thyronorm daily. his next blood test is scheduled for next week. but since the past month he has been keeping unwell, with recurrent cough and cold and fever. last week he even had to take antibiotics for 5 days (Zocef). for the past 2 weeks, he has been passing hard stool, and of very little quantity as well. since starting the antibiotics he has got full blown constipation and i had to give him Duphalac once 2.5 ml. then i am giving him prune juice every day for the past 3 days but still his stool is hard and scanty. my question is, with all his infections, will his CRP levels rise and will that cause elevated TSH? should I wait for some time to let his body lower the CRP and let TSChatDoctore down on its own or get the blood test done right away? our paediatric endocrinologist was confident that his is a transient case and was actually looking forward to reducing the dose on our last visit but now i am afraid that the dose will have to be increased instead.

Thanks for posting on Chat Doctor. Congenital hypothyroidism needs to be treated with thyroxine (thermoform) which is already being given. Generally the dose is reduced after 6 months after checking the levels. Do not worry about it and your pediatric endocrinologist will know what to do as it is a very simple condition. Many child Chat Doctor.  Your doctor is right in this regard.CRP is unrelated to TSH levels and do not link the two. Constipation can occur in response to medicines or diet. Assuming that your child is above 6 months (as you have introduced food like prune juice), you may give high fiber diet to your child, although lactulose should also be effective. Include green leafy vegetables in the mashed and boiled food to be given to him. Vegetables are a major source of fiber. Lettuce, Swiss chard, raw carrots, and spinach are good. You may also give:Tender cooked vegetables, such as asparagus, beets, mushrooms, turnips, and pumpkin. Broccoli, artichokes, squashes, sweet potatoes, and string beans. Vegetable juices. Legumes, such as lentils, black beans, split peas, kidney beans, Lima beans, and chickpeasSunflower seeds, almonds, pistachios nuts, and pecansFruits are another good source of fiber. You can give:Apples and bananasPeaches and pearsTangerines, prunes, and berriesFigs and other
