I had recent blood work that came back low and honestly since December I have been exhausted and I thought that my Dexcom waking me up was part of that. I know it does contribute but I honestly did not think anything was wrong. I have been so tired recently I have been falling asleep really early when watching TV but I still did not clue into that anything was wrong I assumed that the because work has been busier that was the issue. I know things have been so busy with many events and other things I think I was brushing things off. At my Endocrinologist appointment the Dr, asked me if I was having chest pains but I said no but I had forgotten that three weeks ago yes I was having chest pains but I thought it was my Asthma acting up. It can be so easy at times to think it due existing conditions instead of something new. There is a family history of pernicious anemia. Which is a vitamin B12 deficiency. It is an autoimmune disease as well. I currently have experienced all of the symptoms of pernicious anemia over the past couple of months. Such as tiredness, faster heart beat, peeling lips or feeling dehydrated, dizziness, headache and chest pains. I am really hoping its not pernicious anemia but everything my Dr. asked me about were the symptoms of pernicious anemia. Hoping my B-12 goes back up with the vitamins I have been taking for a week.
