Does methylmalonic acid level decrease so quickly?
I had a blood work in January and was diagnosed with anemia, with slightly low RBC and slightly high MCV. My PCP recommended me to take B12 and iron without doing any further blood work now. Instead, she told me to have a blood test for B12 2 months later.
I wanted to know my CURRENT B12 level. So, a few days after starting using the spray B12 (500 mcg/spray, twice a day), I decided to take the test for B12 and MMA on my own.
I received the result today, and was so surprised! My B12 was as high as 1394, while my MMA was as low as 43! I was assuming that I was very deficient in B12, but the result was totally opposite.
Would it be possible that the oral spray elevated my B12 level and lowered my MMA level so quickly?
I have been experiencing daytime sleepiness, lightheadedness, fatigue and oral blood blisters since several years ago, even before I was diagnosed with anemia, and I am still experience these symptoms.
It is hard to tell if the symptoms are improving, because these symptoms always come and go. And, I am aware that it takes time for the blood cell count to return to normal.
