NOW BP MAYBE OK. Asymptomatic chronic low blood pressure is generally not a problem. However, some possible causes: low thyroid, low cortisol, heart disease, dehydration, blood loss, allergic reaction (anaphylaxis), infection (sepsis). You may need lab tests to check these possibilites.
Less than 60. Please see this site for more info. Http://www. Mayoclinic. Com/health/low-blood-pressure/ds00590.
Not many. Not many and not that important. Most common reason would be aortic insufficiency (leaky aortic valve). Other than that, there are artifacts (errors) taking the blood pressure in someone with rigid arteries that will make diastolic BP artificially low. True diastolic low BP (not related to leaky valve) requires NO treatment.
Sure. A low diastolic is not bad, in and of itself. Mine is <50. What could be a problem is if it is usually >70 or 80, and then suddenly drops to 60, you don't have enough pressure during the resting phase of your heart beat to keep blood pressure or flow to the brain.
Valve issue. It can be a sign of a specific type of heart valve condition. I recommend seeing a cardiologist for an evaluation.
Nothing. In health, your body lowers your diastolic pressure to whatever is required to maintain proper perfusion of blood to your entire body. There's really no such thing as 'low diastic pressure' in my opinion, and I've never seen in four decades in medicine anything to make me think this is something you should worry about.
Aging. As we age vessels become stiffer. Stiffer vessels are associated with this.
Many causes. Dr. Fisher correctly notes that the most common causes is stiffening of the vessels as we age. Widened pulse pressure (the difference) is common if you're simply excited, athletic, have a fever, are hyperthyroid, have paget's of the bone or a dialysis shunt, are anemic or pregnant, or have an aortic valve that won't close right.
Good health. A low diastolic is not bad, in and of itself. Mine is <50. What could be a problem is if it is usually >70 or 80, and then suddenly drops to 60, you don't have enough pressure during the resting phase of your heart beat to keep blood pressure or flow to the brain.
