Question for MD. I have had diarrhea for over 2 years, ranging from soft stools to water. Anyways, I feel fine but went to the doctor recently for this condition. He took blood tests and a stool sample. The stool sample was negative for parasitic or bacterial infection as well as occult blood. However, by CBC revealed a hemoglobin of 17.9, a slightly elevated red blood count and a platelet level of 136. He recommended follow up labs a month later which I had done. My Hemoglobin went up to 18.0, RBC was still slightly elevated. My platelets had gone up to 147. He is referring me to a hematology/oncology Dr. and I will be keeping this appointment. I am a 27 year old male who feels in good health. COuld the chronic diarrhea cause the elevation in RBC and hemoglobin? If not then I am worried about possible PV. I should note that my White blood count was normal at 5.5. Please advise. Thanks!
