Sometimes, the cause of nosebleeds can’t be determined. Frequent nosebleeds may mean you have a more serious problem. For example, nosebleeds and bruising can be early signs of leukemia. Nosebleeds can also be a sign of a blood clotting or blood vessel disorder, or a nasal tumor (both non-cancerous and cancerous).

Having high blood pressure puts you at a heightened risk of developing potentially life-threatening conditions like a heart attack or stroke. High blood pressure is sometimes called the silent killer because it often doesn’t cause any noticeable symptoms. Nosebleeds generally are not a symptom of high blood pressure.

Heart conditions like hypertension (high blood pressure) and congestive heart failure can also cause nosebleeds, as can hypertensive crisis — a sudden, rapid increase in blood pressure that may be accompanied by a severe headache, shortness of breath, and anxiety, according to the American Heart Association (AHA).

The American College of Cardiology (ACC) and the American Heart Association (AHA) updated their guidelines in 2017 to recommend men and women who are 65 or older aim for a blood pressure lower than 130/80 mm Hg.

The previous guidelines set the threshold at 140/90 mm Hg for people younger than age 65 and 150/80 mm Hg for those ages 65 and older. This means 70% to 79% of men ages 55 and older are now classified as having hypertension. That includes many men whose blood pressure had previously been considered healthy.

high blood pressure is considered to be 140/90mmHg or higher (or 150/90mmHg or higher if you’re over the age of 80) ideal blood pressure is usually considered to be between 90/60mmHg and 120/80mmHg.
