Orthostatic hypertension involving the systolic BP is known as systolic orthostatic hypertension. High diastolic blood pressure measured while standing in a person who stood up shortly after waking up. When it affects an individual's ability to remain upright, orthostatic hypertension is considered as a form of orthostatic intolerance.
The basic physiological change that occurs in the body during prolonged standing or sudden stand from supine position is that there will be increased pooling of blood in the legs. This decreases the venous return, and so there will be decreased cardiac output, which ultimately causes systolic blood pressure to fall (hypotension).
Even small increases in the blood pressure may be sufficient to maintain blood flow to the brain on standing. [33] In dysautonomic patients who do not have a diagnosis of high blood pressure, drinking 2–3 liters of fluid a day and taking 10 g of salt can improve symptoms, by maximizing the amount of fluid in the bloodstream.

Standing for more than two hours a day saw increased circulatory disease risks. Standing too much can raise the risk of circulatory disease, a new study says. Experts say the key is to 'just move.'
Postural orthostatic tachycardia syndrome (POTS) is a condition characterized by an abnormally large increase in heart rate upon sitting up or standing. [1] POTS is a disorder of the autonomic nervous system that can lead to a variety of symptoms, [10] including lightheadedness, brain fog, blurred vision, weakness, fatigue, headaches, heart palpitations, exercise intolerance, nausea ...
With paroxysmal nocturnal dyspnea specifically, it is felt while sleeping and causes a person to wake up after about 1 to 2 hours of sleep. [ 3 ] More serious forms of dyspnea can be identified through accompanying findings, such as low blood pressure, decreased respiratory rate, altered mental status, hypoxia, cyanosis, stridor, or unstable ...
Menopause can also cause night wakings due to hot flashes, as can an enlarged prostate, as it often leads men to urinate more frequently at night. ... Many people who wake up at night head to the ...
