does affect autoimmune functions.
But if you are TPO positive, that cannot happen suddenly.
Was your TPO also normal before pregnancy, or were only thyroid functions done.
As you might be aware, TSH of 17 is quite raised, and periconceptional TSH is recommended to be below 2.5.
So it might affect the fetus as it is the crucial time of development, and also lead to preterm labour and obstetric adverse effects for the mother, if untreated.
You should consult an endocrinologist
, and start the appropriate dose of levothyroxine
, and alongwith that monitor the TSH to maintain it to 2.5 or less.
Most patients need lifetime therapy, and autoimmunity further increases that chance.
compounds the effects of hypothyroidism
, you should also take adequate calcium and vitamin D supplementation in the second trimester.
