M>Not medical advice M>Joe Murray I had three children and a miscarriage (Placenta found, no foetus evident) in two and a half years(six children all told). I was considered very healthy. Sure as heck didn't suffer from infertility. I had another child after my last son. The mystery was that he never again manifested any signs of a blood dyscrasia. He's seldom been ill.That was 1958. My CD and DH did not show signs until 1972 and I was misdiagnosed until 1985. Never received any suggestion of a blood problem and certainly never was given any treatment for same. I don't take any medication-even vitamin supplements! Another son became ill in college and was diagnosed as thrombocytopenia. He never again showed any blood anomaly after that acute phase. It was my mother who, along with each of her eight siblings, had a partial gastrectomy. She lived thirty two years after that, died at age 97, and ate bread until her last day on earth. I am still not considered delicate. My friends consider my Celiac Disease a neurosis. I wish it were imaginary! AMS
