what are the causes of blood not clotting?

Hemophilia is a rare disorder in which your blood doesn't clot normally because it lacks sufficient blood-clotting proteins (clotting factors). If you have hemophilia, you may bleed for a longer time after an injury than you would if your blood clotted normally. Small cuts usually aren't much of a problem.

There are many possible causes of blood loss. Accidents, surgery, childbirth, stomach ulcers, and blood vessel rupture can cause a sudden loss of blood. In addition, illnesses such as cancer and leukemia often result in lower-than-normal numbers of blood cells.

Low iron—or cases of anemia—can amount to easy bruising. Anemia is the condition in which the blood doesn't have enough healthy red blood cells, which can be caused by disease or a vitamin deficiency, like iron deficiency.

Pulmonary embolism and surgery PE has many possible causes. The most common cause is prolonged bed rest. When you don't walk or move your legs for long periods, blood doesn't circulate as well as it should. Blood pools or collects in the veins and blood clots can form.

Bleeding disorders such as hemophilia and von Willebrand disease result when the blood lacks certain clotting factors. These diseases are almost always inherited, although in rare cases they can develop later in life if the body forms antibodies that fight against the blood's natural clotting factors.

Low blood pressure that causes an inadequate flow of blood to the body's organs can cause strokes, heart attacks, and kidney failure. The most severe form is shock. Common causes of low blood pressure include a reduced volume of blood, heart disease, and medications.

When this happens, lightheadedness and fatigue may be the first noticeable symptoms that you are losing blood. Heavy menstrual bleeding also can cause this type of lightheadedness. Sometimes the cause of lightheadedness is an abnormal heart rhythm (arrhythmia), which can cause fainting spells (syncope).

Because blood does not clot properly without enough clotting factor, any cut or injury carries the risk of excessive bleeding.
