I was discharged from Nelson Hospital last evening after receiving 4 units of blood (brought my haemoglobin up to 107: normal is 120+). I also had another gastroscopy that revealed the ulcers have almost healed!
That was good news, but it means that the doctors are still not certain what is causing the slow blood loss. They believe it is probably aggravation to the lining of the stomach and the duodenum still being caused by the after-effects of the radio-active spheres. The surgeon took a biopsy and I should have his opinion within a few days
