Hi.
48 years old men in normally very healthy condition.
5foot7.. 68 kilo. Lifting weights.
Had blood works in November 2020 done as part of yearly checkup. All was perfect. Including ferritin.. iron levels and hemoglobin. Had pfizer vaccine first dose in march 2021 with no apparent side effects. Minimal pain. Started to feel tired and out of breath a few months later. Had one episode where I could not get back to my bed at night during a bathroom break and had to lay on the floor for some minutes before reaching my bed. Went to do blood work in June 2021 and they revealed I had extremely low iron levels. A hemoglobin of 99 (from140... view screenshot for overtime evolution). Since I did not do a blood test in march before vaccine then the drop would be steeper of the drop started then. Saw a hematologyst that prescribed me two iron pills of 150mg of iron a day. Did some ultrasound. CT imaging. Colonoscopy all perfectly normal. Due to the iron pills my blood level stabilized and I'm no longer anemic. However my hematologist was not satisfied with the iron level recovery based on the amount of pills I was taking a day. I just completed a gastroscopy last week to rule out stomach ulcers. All was completely fine. My hematologyst called my condition a mystery. I mentioned the possibility it could be linked to the COVID vaccine due to the strange timing. And complete lack of other cause. My hematologist dismissed it completely. And said it could be micro blood vessels in my intestine that could lose 5ml of blood a hour. So 120 ml a day . That could explain my case. However it would be not detectable. I still find it strange that I had no issues post vaccine. And that it was so quickly dismissed as a cause. That cause me to search the internet and fall on this post. I also did not find any research on that. Besides those people that had the same story as me. I'm now fine. All my organs have been checked. But still have to take 300mg of iron a day to maintain normal blood levels. I never gived blood. And since I'm male I have no menstruation;)
