I am writing about my son who just underwent a blood transfusion as his red blood cell count was critically low. A grown man should have a red blood cell count between 12-15 my sons (25) red cell count was at 5. After his blood transfusion, three days later it has gone up to 9. The doctors seem to be saying this is because he has Crohn's is there any connection between Crohn's disease and low red blood cells counts. He take 4 pills once a day of Lialda, 1.2 grams each pill a total of 4.8 grams per day. He is sick, very very thin and miserable. We live in Los Angeles and need a better doctor as the one he now sees at Kasier does not seem to be able to make him any better. If you could tell me anything about why his red blood cell count is going down due to having Crohns it might be somewhere to start. Thanks much !
