Brief Answer:
You have to increase the dosage, ideal TSH is less than 2.5
Detailed Answer:
Hi XXXX,
Welcome to HCM. I have gone through your question and understand your concerns.
The thyroid hormone requirement is around 30% higher in pregnancy. In normal woman: hormone production increases by 30% naturally due to the effect of pregnancy hormones. In those with hypothyroidism, this won’t happen as their thyroid is damaged. So we have to increase the pre-pregnancy dose by 30% once you are pregnant.
The tests that we do in pregnancy are total T4 and TSH every month throughout pregnancy. T4 will be high in pregnancy - the normal value (usually 7.5 to 18) will be 1.5 times the normal given in lab (usually 5 to 12). The target TSH in pregnancy is less than 2.5 miu/ml in first 3 months and less than 3 miu/ml in remaining 6 months of pregnancy.
Your TSH is above normal target in pregnancy. Are you taking medictions regularly? If I were your treating endocrinologist, I would have increased the dose to 125-150mcg by now and followed up monthly with total T4 and TSH values. Please consult a physician or preferably an Endocrinologist and adjust your medication.
Hope I have answered your query. If you have any further questions I will be happy to help
With warm regards,

Brief Answer:
Diet issues + Do's and Don'ts
Detailed Answer:
Hi XXXX,
Welcome back
I will explain these two questions
1. Diet in hypothyroidism
Diet depends on cause of hypothyroidism. 2 major cause are Hashimoto's hypothyroidism ( auto immune) and iodine deficiency hypothyroidism. In iodine sufficient areas like XXXXXXX majority are Hashimoto's hypothyroidism
Hashimoto's: No diet restrictions. Can take whatever you wish.
Iodine deficiency hypothyroidism: Iodine rich diet in excess like iodised salt, sea foods etc. Avoid diet that decrease iodine content like partially cooked cabbage, cauliflower and tapioca
You can do anti thyroid antibodies to differentiate these two.
2. Do's and don't 's
Buy tablet only in manufacturers bottle (not as loose tablets).
Keep the tablet in a sun protected area.
Take the tablet in morning empty stomach (at least 4 hrs after meal)
