Hello @hopeful33250 I wanted to follow up. I was trying to find a new PC because mine is not listening to me. I had no option but to follow up with my regular PC. He informed me that everyone had low Vitamin D and that it had been a waste of time to test it. Although, I felt a little better after I began taking Vitamin D. Because of the lab results, he had to follow up with some more blood work. I felt like he thought I was wasting his time. As a result of the new blood work I have learned that I am anemic and my B12 was very low. I have to have a B12 shot once a week for 4 weeks and then once a month for 5 months. He also told me to take 325mg of iron per day. I had my first shot of B12 and am going to begin the iron tonight. I am a bit concerned about the side effects of taking such a high dose of iron. I asked about the thyroid test and he did not order it. After I asked,he asked the lab to test the TSH??? I am waiting to hear about that. My liver was fine. I can now see why I was so exhausted all the time. Hopefully, I will begin to have more energy as I build up my low levels.
