D70-D77: Other diseases of blood and blood-forming organs

The group of conditions encapsulated in the category of "Other diseases of blood and blood-forming organs" covers a range of illnesses that impact the body's blood or its ability to produce blood. This broad category includes conditions like neutropenia, a state of unusually low levels of neutrophils, a type of white blood cell that helps the body fight off infections. Diseases in this group can result from a variety of causes, including genetics, exposure to certain chemicals or drugs, or as a side effect of treatments like chemotherapy. Signs of these conditions can vary, but common symptoms may include fatigue, frequent infections, easy bruising or bleeding. Over time, these diseases can impact the body's ability to deliver oxygen, fight infections, and clot blood. The progression of these illnesses can vary widely, from slow and chronic to rapid and acute, depending largely on the specific condition and the individual's overall health.
