I wanted to ask if it is possible to have hypothyroidism even when thyroid levels appear normal. My recent test results show T3 at 130, T4 at 9.71, and TSH at 1.23, all within the normal range. However, I am experiencing several symptoms such as brain fog, anxiety, slowed thinking, extreme laziness, and memory issues. Could these symptoms still be related to a thyroid issue despite the normal lab values?

Your TSH is within normal limits, but your symptoms suggest that your body may still be sensitive to thyroid changes. Some people feel symptoms even with normal reports. Nothing to worry, just consult an endocrinologist to explore further. Low Vitamin B12 can also contribute to fatigue, so to rule it out, get done Vitamin B12 levels checked

Please check the attached reports, which include CBC, thyroid, and other test results. I tested COVID positive last month. I have been taking a 50 mg thyroid tablet for the past 5 years.

I got my report today. It says LH level 13.36, Prolactin 28.45 and TSH 5.970. What does it mean? Do I have infertility?

Answered by Apollo Doctors

My wife is pregnant with a duration of one month and twenty four days. We consulted a gynecologist and did some blood and urine tests. In the test report my wife TSH shows 10.6 which is beyond the normal range of 2 to 4.68. We called the doctor and they said to please consult with the nearest physician for TSH treatment to start, but due to lockdown the nearest physician is not available. Please suggest any medicine for TSH control? I have attached the test report. Is there any further abnormality? Please do the needful. Thank you.
