Since peritonitis, sepsis, blood transfusion coma etc in 2003 im extremely fatigued 24/7. iron, caffeine nothing helps. opposite of how i used 2b. why?

Complex problem.: After a life-threatening bout of peritonitis and sepsis, there can be many potential problems which could be causing your fatigue. If you have not already, I would recommend going to a primary care doctor for a complete check up and laboratory evaluation, including having your liver and your thyroid checked. If all is normal, further testing may be necessary. Good luck.
