Thank you for your query..
Lets take one thing at a time
1. Thyroid. Well a raised TSH
or less functioning thyroid. But since T3 and T4 are normal, it is not significant. It will be helpful if you consult a pediatric endocrinologist
for the same. But for now i think you should have a repeat TSH before any drugs are started.
2. Constipation: Hypothyroidism is one of the causes of constipation and it may be related. However improper diet is one of the most contributory factor. Try to give your child a lot of fibres like vegetables, fruits and a lots lots of fluids. Sweeten her milk with additional two teaspoon sugar in every glass. It acts as a laxative. Else you can see a pediatric surgeon for a prescription of a laxative too. He will also be able to rule out other causes of constipation like fissure.
3. Scarred kidney: If your child has had recurrent urinary infection (burning micturation with cloudy urine and fever
) then you should get her evaluated for vesico ureteric reflux (it is a condition in which urine from bladder goes back to kidneys and can cause scarring). Your child should be on low dose daily antibiotics and should be further evaluated. I suggest you visit a pediatric surgeon for further evaluation
Hope that solves your query
God bless you
