Blood Disorders: Symptoms, Causes, Diagnosis & Treatment
Blood plays a vital role in keeping the body healthy. It carries oxygen and nutrients to tissues, helps fight infections, and controls bleeding after an injury. When any part of the blood does not function properly, it can affect many organs and lead to a wide range of health problems.
Blood disorders are conditions that affect one or more components of the blood, including red blood cells, white blood cells, platelets, or plasma. Some blood disorders are mild and easily treated, while others require long-term medical care. Understanding the symptoms, causes, and treatment options can help patients seek timely care and prevent serious complications.
What Are Blood Disorders?
Blood disorders are a group of diseases that interfere with the normal function or production of blood cells or blood plasma.
The blood contains four main components:
Red Blood Cells (RBCs): Carry oxygen throughout the body.
White Blood Cells (WBCs): Help fight infections.
Platelets: Help stop bleeding by forming blood clots.
Plasma: The liquid portion of blood that carries nutrients, hormones, proteins, and waste products.
A problem affecting any of these components can result in a blood disorder.
