Grades and stages of high blood pressure
High blood pressure (hypertension) is one of the most common diseases in Western societies. Among people over 45, the hypertension rate is already almost 50 percent and its rising.
High blood pressure means an increased pressure in the arteries. By definition, blood pressure is considered normal if it is below 130/85 mmHg. Its considered high-normal up to values under 139/89 mmHg. Blood pressure can vary a lot depending on the situation and from person to person, but a consistently elevated blood pressure above 140/90 mmHg is regarded as high blood pressure.
Grade 1 hypertension refers to mild hypertension with systolic values between 140 and 159 mmHg and/or diastolic values between 90 and 99 mmHg. Although it's often called "mild hypertension," these values are already elevated and should not be taken lightly.
In consultation with your treating doctor, lifestyle changes may already be enough to bring the values back into the normal range; however, sometimes medication is necessary.
Please note that, according to the German Hypertension League's guidelines, a home blood pressure measurement of >=135 and/or >=85 mmHg is considered high blood pressure.
Grade 2 hypertension already shows clearly elevated blood pressure values systolic 160179 mmHg and/or diastolic 100109 mmHg. At this stage, medication is required in addition to the lifestyle changes mentioned above.
Grade 3 hypertension is present when systolic pressure is at or above 180 mmHg and/or diastolic pressure is at or above 110 mmHg. Regardless of the stage of hypertension, there is a high risk of cardiovascular complications. To reduce this risk, medication is urgently needed alongside an appropriate lifestyle.

The WHO also divides hypertension that is, the disease of high blood pressure into three stages:
- Stage I = no organ changes
- Stage II = with organ involvement enlarged left side of the heart (left ventricular hypertrophy), mild blood-pressure-related changes in the retina (retinopathy), mild blood-pressure-related kidney damage (proteinuria)
asymptomatic, i.e., the person does not yet notice the existing damage - Stage III = hypertensive organ damage left-sided heart failure (the heart no longer pumps at full strength), damage to the central nervous system, more advanced retinal changes with bleeding, and kidney failure
at this stage the damage is usually noticeable to the affected person
