Blood Diseases

There are many types of blood diseases. Some, such as hemophilia, a condition in which blood does not clot normally, are inherited. Others, such as iron-deficiency anemia, may result from heavy menstrual periods, ulcers, colon polyps and even an iron-poor diet, making you dizzy, cold, weak and irritable. Still others, such as sepsis, which is an overstimulation of the immune system, are caused by infection.
