| Addison-Biermer disease | <haematology> A form of anaemia (low red blood cell counts) that results when the bone marrow fails to produce adequate numbers of red blood cells due to a deficiency in vitamin B12. Intrinsic factor, necessary for normal B12 absorption, may be the underlying cause for B12 deficiency if is not produced in the gastric glands (in the stomach). Origin: Gr. Haima = blood (27 Sep 1997) |
| Addison's disease | <endocrinology> A rare endocrine disease that results from the underproduction of aldosterone and cortisol (hormones) by the adrenal glands. Symptoms include weakness, low blood pressure, anaemia, low blood sugar and electrolyte abnormalities. (27 Sep 1997) |
