Orthostatic hypotension symptoms: Going from a sitting or lying position to a standing position often brings out symptoms of low blood pressure. This occurs because standing causes blood to "settle" in the veins of the lower body, and this can lower the blood pressure. If the blood pressure is already low, standing can make the low pressure worse, to the point of causing symptoms. The development of lightheadedness, dizziness, or fainting upon standing caused by low blood pressure is called orthostatic hypotension. Normal individuals are able to compensate rapidly for the low pressure created by standing with the responses discussed previously and do not develop orthostatic hypotension.

If your blood pressure is above the normal range for up to 5 readings (taken at different visits), your doctor will likely diagnose you with high blood pressure. Sometimes the doctor may diagnose you after a fewer number of readings, depending on how high above normal your blood pressure is and if you have other medical conditions. Blood pressure tends to be at its highest during exercise, physical work, or stress, and lowest during sleep. Everyone can have a temporary increase in blood pressure at one time or another, which is why it's important to take multiple readings.
A recent study compared diuretics with other types of blood pressure-lowering medications and found the diuretics were just as effective as the newer drugs in preventing heart attack or death due to heart disease. The new guidelines say these inexpensive drugs should be used as first-line treatment for most people who have high blood pressure without other risk factors such as heart failure, history of heart attack, diabetes, or kidney disease.
Finding out what genetic patterns contribute to high blood pressure risk. NHLBI-funded researchers identified dozens of new genetic variations that affect blood pressure. Scientists discovered the new genetic regions—and confirmed the role of many previously known ones by looking specifically at cigarette smoking behavior, one of many lifestyle factors that impact blood pressure. The analysis of the large samples was possible through the work of researchers in the Gene-Lifestyle Interactions Working Group of the Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) Consortium.
If your blood pressure remains high for a long period of time, you run the risk of damaging your blood vessels. Your stroke risk rises significantly, too. And because your heart is working harder to push blood through your system, that very valuable muscle can become overworked and grow thicker. An enlarged heart causes further complications, including heart failure. Medications and special implantable pumps can help boost heart function. But if you can manage your blood pressure before it gets too high and puts your heart at risk, you may be able to avoid a lot of complications down the road. 

On physical examination, hypertension may be associated with the presence of changes in the optic fundus seen by ophthalmoscopy.[22] The severity of the changes typical of hypertensive retinopathy is graded from I to IV; grades I and II may be difficult to differentiate.[22] The severity of the retinopathy correlates roughly with the duration or the severity of the hypertension.[20]
Cirrhosis of the liver is the most common cause of portal hypertension. In cirrhosis, the scar tissue (from the healing of liver injury caused by hepatitis, alcohol, or other liver damage) blocks the flow of blood through the liver. Blood clots in the portal vein, blockages of the veins that carry blood from the liver to the heart, parasitic infection (schistosomiasis), and focal nodular hyperplasia are also causes of portal hypertension.
Dr. Ogbru received his Doctorate in Pharmacy from the University of the Pacific School of Pharmacy in 1995. He completed a Pharmacy Practice Residency at the University of Arizona/University Medical Center in 1996. He was a Professor of Pharmacy Practice and a Regional Clerkship Coordinator for the University of the Pacific School of Pharmacy from 1996-99.
Orthostasis literally means standing upright. Orthostatic hypotension, or postural hypotension, is defined as a decrease in systolic blood pressure of at least 20 mm Hg or at least 10mm Hg within 3 minutes of the patient standing. If orthostatic hypotension is present, the client may be at risk of falls and should be closely supervised with ambulation or advised to call for assistance with activity.

Calcium channel blockers are drugs that reduce the movement of calcium into cells of the heart and vessels. This reduces the strength of heart contractions and relaxes the arteries, allowing them to remain more open, lowering blood pressure. Side effects of calcium channel blockers can include heart palpitations, dizziness, swollen ankles, and constipation. Calcium channel blockers can be taken alone or with other blood pressure medications. They should be taken with food or milk. Because of potential interactions, those taking calcium channel blockers should avoid alcohol and grapefruit juice.


Heart attack. Signs of heart attack include mild or severe chest pain or discomfort in the center of the chest or upper abdomen that lasts for more than a few minutes or goes away and comes back. It can feel like pressure, squeezing, fullness, heartburn, or indigestion. There may also be pain down the left arm. Women may also have chest pain and pain down the left arm, but they are more likely to have less typical symptoms, such as shortness of breath, nausea, vomiting, unusual tiredness, and pain in the back, shoulders, or jaw. Read more about the signs and symptoms of a heart attack.
Chronic low blood pressure with no symptoms is almost never serious. But health problems can occur when blood pressure drops suddenly and the brain is deprived of an adequate blood supply. This can lead to dizziness or lightheadedness. Sudden drops in blood pressure most commonly occur in someone who's rising from a lying down or sitting position to standing. This kind of low blood pressure is known as postural hypotension or orthostatic hypotension. Another type of low blood pressure can occur when someone stands for a long period of time. This is called neurally mediated hypotension. When it leads to passing out, if is called vasovagal syncope.
There are even more medication types that can lower blood pressure. Some of these are alpha blockers, vasodilators, and central alpha agonists. Your doctor may prescribe these medications if other medications have been ineffective or if you have another condition along with hypertension. Side effects can include fast pulse, palpitations, dizziness, diarrhea, or headaches.

Lifelong control of hypertension will minimize the risk of developing heart attack, stroke, kidney failure, blindness, and a variety of other illnesses. Unlike other illnesses in which medications are taken for only a short period of time, high blood pressure medication is usually expected to be taken for the rest of the individual's life. It is uncommon, but not rare, that significant lifestyle changes can lower blood pressure readings to normal.

The findings mean that an additional 14 percent of U.S. adults, or about 30 million people, will now be diagnosed as having high blood pressure, compared with the number diagnosed before the new guidelines. This will bring the total percentage of U.S. adults with high blood pressure to 46 percent, up from 32 percent previously. [9 New Ways to Keep Your Heart Healthy]

In short, everyone. The motivation behind the change was to make people healthier. With more sensitive guidelines, we are able to get in control of our blood pressure sooner and improve heart health before reaching levels that could cause more serious health problems. For some, the changing guidelines may result in antihypertensive (blood pressure lowering) medication, along with lifestyle management, but that will not be the case for everyone.

Much is being made of the fact that the new definitions of high blood pressure will mean roughly half of all US citizens will be considered to have high blood pressure, but when you really look at the numbers, as cardiologists already have, not that many more people will actually be advised to take medications. Although the public has good reason to be suspicious of “big pharma,” that’s not what this is about.
In the 19th and 20th centuries, before effective pharmacological treatment for hypertension became possible, three treatment modalities were used, all with numerous side-effects: strict sodium restriction (for example the rice diet[152]), sympathectomy (surgical ablation of parts of the sympathetic nervous system), and pyrogen therapy (injection of substances that caused a fever, indirectly reducing blood pressure).[152][158]

Normal blood pressure is less than 120/80. Knowing your blood pressure and remembering to check it regularly can help save your life. Choosing healthier, heart-conscious foods, maintaining a healthy weight, getting up and staying active, and managing your stress are great ways to help keep your blood pressure at the level it should be. Learn more about what you can do to help control your blood pressure.
Your doctor may diagnose you with high blood pressure when you have consistent systolic readings of 140 mm Hg or higher or diastolic readings of 90 mm Hg or higher. Based on research, your doctor may also consider you to have high blood pressure if you are an adult or child age 13 or older who has consistent systolic readings of 130 to 139 mm Hg or diastolic readings of 80 to 89 mm Hg and you have other cardiovascular risk factors.
Angiotensin receptor blockers prevent the actions of angiotensin II on the arteries. This means the arteries stay more open and blood pressure is lowered. ARBs can take a few weeks to work. Side effects can include dizziness, muscle cramps, insomnia, and elevated potassium levels. As with ACE inhibitors, women who are pregnant, planning to get pregnant, or breastfeeding should not take ARBs.
Hypertension, the medical term for high blood pressure, is known as "the silent killer." More than 80 million Americans (33%) have high blood pressure, and as many as 16 million of them do not even know they have the condition. If left untreated, high blood pressure greatly increases your risk for heart attack and stroke. Hypertension is projected to increase about 8 percent between 2013 and 2030.
She'll inflate the cuff to a pressure higher than your systolic blood pressure, and it will tighten around your arm. Then she'll release it. As the cuff deflates, the first sound she hears through the stethoscope is the systolic blood pressure. It sounds like a whooshing noise. The point where this noise goes away marks the diastolic blood pressure.

Changes in blood vessel structure. Blood vessels have layers of the proteins elastin and collagen. Elastin is what makes blood vessels flexible. Collagen, which is stiffer, gives vessels structure. With age, elastin breaks down. Even the elastin that remains becomes less elastic. Meanwhile, collagen deposits in the vessels increase. As a result, blood vessels grow thicker and bend less easily over time. These changes may lead to higher systolic blood pressure.
Extremely high levels of blood pressure, i.e. systolic above 180 mm Hg or diastolic above 110 mm Hg requires immediate medical attention. Delayed treatment in such cases may result in various hypertensive emergencies like stroke, heart attack, hypertensive encephalopathy, malignant hypertension, aortic dissection, etc. These conditions may cause death.
The portal venous system contains veins coming from the stomach, intestine, spleen, and pancreas. These veins merge into the portal vein, which branches into smaller vessels and travel through the liver. Portal hypertension occurs when there is an increase in the blood pressure within the portal venous system. When the vessels in the liver are blocked due to liver damage, blood cannot flow properly through the liver. This causes high blood pressure in the portal system.
Your doctor may suggest that you check your blood pressure at home. The easiest way to do this is to use a digital blood pressure monitor. You can get a monitor from your local drug store, hospital, clinic or online. Your doctor can help you find a monitor that is right for you and show you how to use it. Many pharmacies and grocery stores also have in-store monitors that you can use for free.
A blood pressure reading measures both the systolic and diastolic forces, with the systolic pressure listed first. The numbers show your pressure in units of millimeters of mercury (mm Hg)—how high the pressure inside your arteries would be able to raise a column of mercury. For example, a reading of 120/80 mm Hg means a systolic pressure of 120 mm Hg and diastolic pressure of 80 mm Hg.
Heart attack. Signs of heart attack include mild or severe chest pain or discomfort in the center of the chest or upper abdomen that lasts for more than a few minutes or goes away and comes back. It can feel like pressure, squeezing, fullness, heartburn, or indigestion. There may also be pain down the left arm. Women may also have chest pain and pain down the left arm, but they are more likely to have less typical symptoms, such as shortness of breath, nausea, vomiting, unusual tiredness, and pain in the back, shoulders, or jaw. Read more about the signs and symptoms of a heart attack.
Measuring blood pressure in both the lying (supine) and standing positions usually is the first step in diagnosing low blood pressure. In patients with symptomatic low blood pressure, there often is a marked drop in blood pressure upon standing, and patients may even develop orthostatic symptoms. The heart rate often increases. The goal is to identify the cause of the low blood pressure. Sometimes the causes are readily apparent (such as loss of blood due to trauma, or sudden shock after receiving X-ray dyes containing iodine). At other times, the cause may be identified by testing:
There are even more medication types that can lower blood pressure. Some of these are alpha blockers, vasodilators, and central alpha agonists. Your doctor may prescribe these medications if other medications have been ineffective or if you have another condition along with hypertension. Side effects can include fast pulse, palpitations, dizziness, diarrhea, or headaches.
Normal blood pressure can differ substantially between breeds but hypertension in dogs is often diagnosed if systolic blood pressure is above 160 mm Hg particularly if this is associated with target organ damage.[170] Inhibitors of the renin-angiotensin system and calcium channel blockers are often used to treat hypertension in dogs, although other drugs may be indicated for specific conditions causing high blood pressure.[170]
Optimal blood pressure is less than 120/80 (systolic/diastolic). In healthy people, low blood pressure without any symptoms is not usually a concern and does not need to be treated. But low blood pressure can be a sign of an underlying problem -- especially in the elderly -- where it may cause inadequate blood flow to the heart, brain, and other vital organs.
High blood pressure is a major risk factor for cardiovascular disease. Without treatment, you can have a transient ischemic attack (TIA) or stroke, heart attack, enlarged heart, heart failure, peripheral vascular disease (such as poor circulation and pain in your legs), aneurysms, kidney disease, and broken blood vessels in your eyes. Treatment includes making changes recommended by your healthcare provider.
