?? Thyroid abnormality

Detailed Answer:
Hello ma'am and welcome.

Thank you for writing to us.

I have gone through your query with diligence and would like you to know that I am here to help.

After going through your symptoms, all that came to my mind was a possible thyroid abnormality. So I would like to ask if you ever had your thyroid hormone levels checked? Also, have you experienced any irregularities in your menstrual cycle?

Let me list a few of the most commons symptoms of an under-active thyroid, they are:
-Cold intolerance
-Difficulty concentrating
-Irregular menstrual cycle
-Dry skin
-Muscle and joint aches
-Weight gain and difficulty in losing weight
-Chronic tiredness
-Tremors (rare)
-Growth of hair in unwanted regions like face, chest, etc. (not very common)
and a few others.

If you can relate to most (even if not all) of these symptoms, then please write back to me with a confirmation, and I shall guide you from there on.

I hope you find my response helpful and informative. I would be more than happy to help you further, so please do not hesitate to write back to me anytime.

Best wishes.

Follow-up: What causes dry mouth, leg cramps and lighheadedness? 16 minutes later
Hello again,
I am 65 and menstruation ceased about 8 years ago.
My last blood work was in mid XXXXXXX and thyroid levels were OK according to my DO.
I recently visited Dent Clinic and was told that my problem could be a dip in bp, cardiac arrhythmia, stress or borderline epilepsy. That is the reason for the 24 hour EEG at my convenience before my next visit in 6 months.
All three episodes, with the first last September have been just prior to waking.
I discontinued the keppra in early December and was fine until 5/10/2015.
I am taking the keppra again due to a minor episode then.
I had one this morning which my fiancé says lasted only seconds but I was "out of it" for a few minutes after with an extreme dry mouth.
The keppra is 250 mg twice daily.

Brief Answer:
A few more investigations can be added

Detailed Answer:
Hello once again ma'am.

An EEG should be beneficial in such a case, true. But, I would still like a more elaborate explanation on what is considered to be 'OK' according to your doctor for your thyroid levels. In addition to this, due to a cessation in menstruation you should also check on your levels of sexual hormones.

Please also request for an EMG, a 24-hour ambulatory device to check on blood pressure through the day and with fluctuations with different activities, and a 2D echo for the heart. These investigations should all help in providing a more clear picture into what could possibly causing your symptoms.

Please also request for your thyroid profile reports and write to me with them, so I can better understand and rule out a thyroid abnormality completely.

Please feel free to write to me about anything, and keep me updated so we can together reach to the bottom of this.

Best wishes.
