Her weight is only 26.5. This much dose of the drug will anyway harm her? Any side effects will affect her?

Brief Answer:
contimue thyronorm

Detailed Answer:
Hi
Thanks for writing to health care magic.
Your daughter definitely has hypothyroidism.
Possibly auto immune because of positive tpo antibodies.
This type will need thyroid hormone replacement mostly for many years.
There is no other alternative.
There are no side effects if taken under proper medical supervision and frequently tested.
Regarding the dose you need to continue your present dose and repeat test after every three months.
Target for TSH less than 5.
Wishing your child good health

But today doctor suggested to increase the dose to 75 mg. I fear it is too much for her weight (26.5). What do you suggest? And doctor........ how this happened to my daughter? Is hypothyroidism common to children or rare? What are the reasons?

Brief Answer:
Try with 50

Detailed Answer:
Try with 50 for another month atleast before increasing dose.
Auto immune happens on it's own. It's body fighting against itself. This is common in kids. It is not rare. But easily and should be treated.
