 Show High Blood Pressure HypertensionHigh 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.REFERENCE: CDC. High Blood Pressure. Updated: Nov 13, 2017. OverviewOrthostatic hypotension — also called postural hypotension — is a form of low blood pressure that happens when standing after sitting or lying down. Orthostatic hypotension can cause dizziness or lightheadedness and possibly fainting. Orthostatic hypotension can be mild. Episodes might be brief. However, long-lasting orthostatic hypotension can signal more-serious problems. It's important to see a health care provider if you frequently feel lightheaded when standing up. Occasional orthostatic hypotension is usually caused by something obvious, such as dehydration or lengthy bed rest. The condition is easily treated. Chronic orthostatic hypotension is usually a sign of another health problem, so treatment depends on the cause. SymptomsThe most common symptom of orthostatic hypotension is lightheadedness or dizziness when standing after sitting or lying down. Symptoms usually last less than a few minutes. Orthostatic hypotension signs and symptoms include:
When to see a doctorOccasional dizziness or lightheadedness can be minor — triggered by mild dehydration, low blood sugar or overheating. Dizziness or lightheadedness can also result from standing after sitting for a long time. If these symptoms happen only occasionally, there's likely no cause for concern. It's important to see a health care provider for frequent symptoms of orthostatic hypotension. Losing consciousness, even for just a few seconds, is serious. It requires seeing a provider right away. Keep a record of your symptoms, when they occurred, how long they lasted and what you were doing at the time. Tell your care provider if symptoms occur at times that could be dangerous, such as while driving.

Blood pressure drops because there's less blood flowing back to the heart. Usually, special cells (baroreceptors) near the heart and neck arteries sense this lower blood pressure. The baroreceptors send signals to the brain. This tells the heart to beat faster and pump more blood, which evens out blood pressure. These cells also narrow the blood vessels and increase blood pressure. Orthostatic hypotension occurs when something interrupts the body's process of dealing with the low blood pressure. Many conditions can cause orthostatic hypotension, including:
Risk factorsThe risk factors for orthostatic hypotension include:
ComplicationsPersistent orthostatic hypotension can cause serious complications, especially in older adults. These include:
