What controls the diastolic pressure?

Vascular tone. Both systolic and diastolic pressures are significantly impacted by the level of vascular tone or "resistance" or restriction to a given rate of blood flow. Although we have excellent medication options for managing vascular resistance, I have found that good cardiovascular conditioning seems to positively impact the diastolic blood pressure by enhancing "run off" in the peripheral vascular bed.

Why could diastolic pressure be high?

Several reasons. Most high blood pressure is idiopathic (no reason, you just have it) whether it is systolic or diastolic. It runs in families so if your parents have it, you are more likely to get it. There are occasion cases secondary to specific causes such as adrenal tumors, kidney problems, or narrowing of the aorta (called coarctation) and that is called secondary hypertension.
Age is #1. Risk factor. Our arteries stiffen as we age. Obesity & sedentary life style as well as excessive alcohol.

What can low diastolic pressure mean?

Not much. A lower diastolic number means nothing unless it's less than what's expected to be normal for a particular patient, based in overall health and age.
Several causes. Advanced generalized arteriosclerosis, severe aortic insufficiency, thyrotoxicosis, anemia or measurement artifact are the most frequent culprits.

What can high diastolic pressure mean?

Needs evaluation. High blood pressure either systolic or diastolic needs evaluation and treatment to prevent complications such as stroke, heart attack, or kidney damage.
Blood pressure. High diastolic pressure implies a high intravascular volume relative to the peripheral vascular resistance. Many situations can be associated with this.

What does diastolic pressure relate to?

Artery Stiffness. The diastolic blood pressure or the "bottom number" when the blood pressure is taken is when the pressure at which the heart beat is no longer heard by the stethescope. It is related to the stiffness of the arterial tree in the body. The stiffer the artery the higher the diastolic pressure.
Diastolic BP. That is the pressure in the arteries when they are relaxed. Normal should be 80 or less.
Diastolic pressure. Related to peripheral vascular resistance and intravascular blood volume in diastole.

How can I treat low diastolic pressure?

Hydration. Drink plenty of fluids. Make sure there is no valvular/structural heart disease.
Placebo 10mg. Low diastolic pressure is, generally speaking, good. It means your vessels have high compliance. At 25, you're probably in good shape. If you're worried, see your doc.

When can diastolic pressure be measured?

Whenever you want. Diastolic blood pressure refers to the pressure in the arteries during the period of heart's relaxation, i.e. Once it finished ejecting blood during contraction. For every single heart beat, there is the period of contraction ("systolic blood pressure") and the relaxation ("diastolic"). In any single cardiac cycle, each of these arterial pressures can be measured.
Regular. The regular blood pressure machine will measure the diastolic pressure. The lower number on the reading represents it.
