Brief Answer:
No. Mildly reduced Vitamin D has little to do with underactive thyroid.

Detailed Answer:
Hi

I understand that you suffer from Underactive thyroid, also known as hypothyroidism. Hypothyroidism is very common in women of your age and the most common etiology is autoimmune (sometimes also called Autoimmune thyroiditis or Hashimoto's thyroditis)

Vitamin D deficiency is also very common. Studies have shown that vast majority of people living in Urban area suffer from vitamin D deficiency. There is recently a trend to link everything from muscle ache to cancer with vitamin D deficiency. However, so far only few conditions have been linked with vitamin D deficiency with reasonable certainty. Vitamin D is known to have some effect in certain autoimmune disorders. However, the link between a mild vitamin D deficiency as in your case and underactive thyroid has not been proven.

So answer your question, no there is no proven link between the two. I would suggest you not to worry about the etiology and focus on the treatment of the two conditions, which are relatively easy to treat.

Thank you. The problem is that both my T4 and tsh levels have now returned to normal yet my symptoms are still the same - fatigue, muscle weakness, tiredness. All my regular blood tests are clear. Have you any suggestions?

Brief Answer:
They may not be related to thyroid

Detailed Answer:
'fatigue, muscle weakness, tiredness' are common symptoms. They are often wrongly attributed to thyroid alone. Though some patients truly have these symptoms because of hypothyroidism, in many cases it is a combination of a number of things which produce these symptoms. Patients often believe that treating the thyroid problem is like a 'magic pill' which will solve all problems. however, this may not be true in all cases.

Stress, adrenal insufficiency, primary ovarian insufficiency, chronic fatigue syndrome, to name a few, are conditions which produce similar symptoms at your age. I would suggest you consult a good physician, who will consider a prospect of an alternative diagnosis to your problem rather the attribute all these to hypothyroidism alone.

These symptoms are definitely not due to your mild vitamin D insufficiency, however, for the purpose of bone health, I would suggest you to regularly take vitamin D supplements.

Good luck

I am currently wearing a 24 hour blood pressure monitor as everytime it is checked it is high. I also know myself it is high as i feel lightheaded, tired and have a faster heartbeat. I had an ECG which did not show any irregular patterns. Could the high blood pressure be contributing to my symptoms?

Brief Answer:
Stress..

Detailed Answer:
Hi

Both your high blood pressure and the symptoms you have described can be attributed to stress.A hormone called 'Cortisol' , if in excess, can also lead to high blood pressure and the symptoms you have described above. If at an age of 29 years , your blood pressure is high, you do need an evaluation.

So your high blood pressure may not be the cause of your current symptoms, but it is certainly related to stress which can cause both the high blood pressure and the current symptoms.

I would suggest you meet a physician, again and explain him/her your symptoms and also have your BP checked by him/her.

Hope this answers it
