  • Unexplained nose bleeds
  • Bleeding gums
  • Heavy bleeding from minor cuts during dental works
  • Heavy menstrual bleeding
  • Bleeding into joints
  • Excessive bleeding following surgery



Erythrocytosis is a condition where the body creates too much red blood cells (RBCs). This condition may also be called polycythemia. A condition where there is too much white blood cells and platelets in the blood. It may be caused by genetic mutations, certain diseases and medications, smoking, and living in high altitudes.

Symptoms of Erythrocytosis:

  • Headaches
  • Dizziness
  • Blurred vision
  • Itching
  • Nosebleeds
  • Shortness of breath
  • Increased blood pressure
  • Skin flushing
  • Weakness and fatigue
  • Pain in fingers



Leukopenia is a condition where the blood has reduced white blood cells. This is caused by bone marrow conditions, auto-immune disorders, cancer and cancer treatment, certain medications, and malnutrition.

Symptoms of Leukopenia:

  • Fever
  • Chills
  • Sweating



Leukocytosis is a condition where the blood has elevated levels of white blood cells. It is caused by infection, surgery, certain medications, certain illnesses, cancer, exercise, emotional stress, and smoking.

Symptoms of Leukocytosis depending on condition:

  • Fever and pain or other symptoms at the infection site
  • Fever, easy bruising, unintentional weight loss, and night sweating for leukemia and other cancers
  • Hives, itchy skin, and rashes on skin caused by an allergic reaction
  • Wheezing and difficulty in breathing due to an allergic reaction in your lungs



Thrombocytopenia is a condition where the blood has a low platelet count. This is caused by bone marrow conditions, certain medications, or problems of the liver or spleen.

  • Easy bruising
  • Prolonged bleeding from wounds
  • Frequent and prolonged bleeding of nose and gums
  • Blood in stool or urine
