Isolated diastolic hypertension (IDH) occurs when only your diastolic blood pressure is high Blood pressure is the force of your blood pushing against the walls of your arteries, which carry blood to other parts of your body. Your blood pressure can be measured using two numbers:
When your blood pressure is consistently higher than 130/80 mm Hg, you are considered to have hypertension. What is isolated diastolic hypertension?With hypertension, typically both systolic and diastolic blood pressures are elevated. However, isolated diastolic hypertension (IDH) occurs when your systolic blood pressure is normal, and only your diastolic blood pressure is high (over 80 mm Hg). IDH is an uncommon type of hypertension, accounting for less than 20% of all hypertension cases. Like other types of hypertension, IDH can increase the risk of stroke, heart disease, heart attack, heart failure, aneurysm, atrial fibrillation, peripheral arterial disease, vision loss and chronic kidney disease. What causes high diastolic blood pressure?Possible causes of isolated diastolic hypertension include:
What causes your blood pressure to suddenly get high?Hypertension or high blood pressure (high BP) is a medical condition Hypertension or high blood pressure (high BP) is a medical condition where the pressure in the arteries is persistently elevated. The heart pumps blood into the arteries, and it is circulated to all parts of the body. Hypertension develops when the heart constantly needs to exert higher force to deliver the blood to the organs through the arteries. Since a hypertensive heart must work harder to deliver blood, hypertension can increase the risk of cardiovascular disease, heart attack and heart failure. Also, the blood vessels in people with hypertension are narrower, putting them at risk of stroke, kidney disease and vision loss. There are many reasons for high blood pressure. Some possible causes include
QUESTIONSalt and sodium are the same. See AnswerWhat are symptoms of high diastolic pressure?Hypertension is generally considered a silent killer. Most people with hypertension do not have any symptoms. It may take many years for the condition to become severe and for symptoms to appear. Many times, these symptoms may be attributed to other issues. The best way to know the blood pressure levels is through regular checkups. Symptoms of severe hypertension include:
What are the main types of hypertension?There are two types of hypertension: 1. Primary or essential hypertensionPrimary or essential hypertension is when the hypertension has no identifiable cause (for example, another disease or condition). It develops gradually over years. This type of hypertension may be the result of multiple factors, including:
2. Secondary hypertensionIn some people, hypertension is caused by an underlying health condition. This type of hypertension tends to appear suddenly. Secondary hypertension also generally causes higher blood pressure than primary hypertension. Secondary hypertension is caused by specific conditions and their complications:

But it's not normal, either. People with elevated diastolic blood pressure often develop elevated systolic blood pressure over time.
Is a diastolic of 100 high?When the bottom number of blood pressure (diastole) is over 100 mmHg, it may be called diastolic hypertension (DHT). The normal range of diastolic pressure should be 60 to 80 mmHg in adults. Anything above this is considered abnormal (hypertension).
What causes your diastolic BP to be high?Anxiety and stress
Certain medications can cause high diastolic blood pressure. These include: Antidepressants. Amphetamines.
