Normal Blood Pressure vs. High Blood Pressure
The American Heart Association sets the guidelines for what constitutes normal blood pressure and high blood pressure, officially known as hypertension. Your blood pressure is classified as normal if the systolic pressure ranges from 90 to 120 mm Hg and the diastolic pressure ranges from 60 to 80 mm Hg. Elevated blood pressure occurs when the systolic pressure measures from 120 to 129 mm Hg, but the diastolic pressure remains below 80 mm Hg.
If your systolic blood pressure measures between 130 and 139 mm Hg and your diastolic pressure is between 80 and 89 mm Hg, you are considered to have stage 1 hypertension. Stage 2 hypertension occurs when the systolic pressure rises to 140 mm Hg or higher and the diastolic pressure measures 90 mm Hg or higher. If your systolic pressure rises above 180 mm Hg and your diastolic pressure goes above 120 mm Hg, it is considered a hypertensive crisis and requires immediate medical attention.
The Dangers of High Blood Pressure
Hypertension potentially leads to other health problems, so it’s important to check your blood pressure regularly to detect it. Because it often doesn’t have symptoms until it causes a hypertensive crisis, it’s known as “the silent killer.” In the most extreme cases, high blood pressure can lead to a heart attack, stroke and possibly even death from those and other conditions. Long-term heart disease can occur when your blood pressure remains high for a long time, especially after age 50. High blood pressure also affects kidney function, vision and your general physical health on a daily basis.
Doctors generally offer a number of solutions to help you maintain your blood pressure at a normal level. The most common way doctors treat high blood pressure that is already classified as stage 2 hypertension is with medication. Daily medications that can help lower your blood pressure include beta blockers, diuretics, calcium channel blockers and ACE inhibitors.
If your high blood pressure is at a lower stage, your doctor may start by recommending you implement various lifestyle changes to help lower your blood pressure. Weight loss, exercise and healthy eating habits are just a few of the lifestyle changes your doctor may recommend, depending on your personal circumstances. These types of changes are also recommended, even if you take medication. You will achieve the best results by following the guidance of your doctor.
The Dangers of Low Blood Pressure
Much less attention is paid to low blood pressure, which is clinically known as hypotension, but it’s also important to see a doctor if your blood pressure is abnormally low. While high blood pressure can often go undetected until it causes other health problems, low blood pressure often has symptoms that are impossible to miss. Signs of low blood pressure include dizziness, blurry vision, clammy skin, fainting, chest pain, balance issues and headaches.
In some cases, low blood pressure occurs for a temporary reason, such as pregnancy, dehydration or a medication that can be adjusted or changed. It can also be caused by various health conditions, including infections, poor circulation and diabetes. In the worst cases, it could indicate underlying heart problems, blood loss and serious endocrine problems.
