- Isolated Diastolic Hypertension
- Blood Pressure Levels
- Types of Hypertension
- Risk Factors
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:
- Systolic (the number on top): pressure exerted when the heart pumps blood throughout the body
- Diastolic (the number at the bottom): pressure exerted when the heart relaxes and refills with blood
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 are symptoms of high diastolic pressure?
If only your diastolic blood pressure is high, you may not experience any symptoms. However, severe hypertension symptoms include:
How is high diastolic blood pressure treated?
Isolated diastolic blood pressure can often be managed with lifestyle modifications, dietary supplements, and medications.
- Maintaining a healthy weight
- Eating a high-fiber diet rich in fruits and vegetables and low in saturated fat and dairy products
- Reducing sodium in the diet
- Exercising regularly
- Quitting smoking
- Limiting alcohol use
- Managing stress
- Getting adequate sleep
- Practicing slow deep breathing
- Monitoring blood pressure at home
Dietary supplements that may help lower blood pressure include:
- Minerals like magnesium, calcium and potassium
- Supplements that widen blood vessels, such as cocoa, coenzyme Q10, L-arginine and garlic
- Omega-3 fatty acids, found fish oil supplements and flaxseeds
If lifestyle and dietary changes are not enough to lower your blood pressure, your doctor may be able to prescribe medications for you.
What are the different blood pressure levels?
|Blood pressure levels||Systolic (mm Hg)||Diastolic (mm Hg)|
|Normal blood pressure||Less than 120||Less than 80|
|Elevated blood pressure or prehypertension||Between 120 to 129||Less than 80|
|Stage 1 hypertension||Between 130 to 139||Between 80 to 89|
|Stage 2 hypertension||140 or higher||90 or higher|
|Hypertensive crisis||Higher than 180||Higher than 120|
What are the main types of hypertension?
There are two types of hypertension:
1. Primary or essential hypertension
Primary 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:
- Blood plasma volume
- Hormone activity
- Physical changes in the body due to age
- Environmental factors, such as stress and lack of exercise
2. Secondary hypertension
In 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:
- Kidney disease
- Congenital heart defects
- Congenital defects in blood vessels
- Obstructive sleep apnea
- Certain endocrine tumors
- Adrenal gland tumors
- Cushing syndrome
- Congenital adrenal hyperplasia
- Thyroid problems
- Certain medications, such as birth control pills, cold remedies, decongestants, pain relievers and some prescription drugs
- Use of illegal drugs, such as cocaine and amphetamines

- Regular tobacco use
- Alcohol abuse
- Male gender
- Sedentary lifestyle
- Lack of exercise
- High fat intake

High Blood Pressure (Hypertension)
High blood pressure (hypertension) is a disease in which pressure within the arteries of the body is elevated. About 75 million people in the US have hypertension (1 in 3 adults), and only half of them are able to manage it. Many people do not know that they have high blood pressure because it often has no has no warning signs or symptoms.
Systolic and diastolic are the two readings in which blood pressure is measured. The American College of Cardiology released new guidelines for high blood pressure in 2017. The guidelines now state that blood normal blood pressure is 120/80 mmHg. If either one of those numbers is higher, you have high blood pressure.
The American Academy of Cardiology defines high blood pressure slightly differently. The AAC considers 130/80 mm Hg. or greater (either number) stage 1 hypertension. Stage 2 hypertension is considered 140/90 mm Hg. or greater.
If you have high blood pressure you are at risk of developing life threatening diseases like stroke and heart attack.

High Blood Pressure SymptomsMost people with high blood pressure have no signs or symptoms, even if blood pressure readings reach dangerously high levels. In some patients, symptoms may include fatigue, headaches, dizziness, confusion, sweating, chest pain and vision problems.
What Does it Mean When the Diastolic Number is High?A high diastolic reading (equal to or greater than 120 mmHg) is linked to a higher risk of disease involving the large artery called the aorta that carries blood and oxygen from the heart to distant body parts. People with an elevated diastolic reading are more prone to develop an abdominal aortic aneurysm (ballooning in the lining of the aorta).
What Is High Blood Pressure (Hypertension)?High blood pressure or hypertension is when the blood pressure readings consistently range from 140 or higher for systolic or 90 or higher for diastolic. Blood pressure readings above 180/120 mmHg are dangerously high and require immediate medical attention.
What Is Considered Stroke-Level High Blood Pressure?Blood pressure readings above 180/120 mmHg are considered stroke-level, dangerously high and require immediate medical attention.
