Hello and welcome to HCM,
You are suffering two disease processes and I will address both your problems one by one.
First of all,
hypothyroidism has to be monitored regularly by serum levels of T3, T4 and TSH levels. Even when on medication, symptoms of hypothyroidism can reappear.
The dose of
thyroxine has to be altered when required.
When talking about conceiving, it is very important to maintain levels of thyroid hormones T3 and T4 during
pregnancy because thyroid hormones are very essential for development of brain of the fetus.
The second issue is that of enlarged
lymph nodes along with a large MT spot (spot more than 15 mm is significant) suggests
tuberculosis.
However, it has to be confirmed.
Some investigations have to be done - aspiration cytology and ZN staining to detect the bacteria causing tuberculosis- TB.
If the test for TB comes out to be positive, anti tubercular treatment has to be taken for 6-9 months.
The drugs for TB can affect the baby so conception is best avoided if infection is positive.
Thanks and take care
Dr Shailja P Wahal
