Orthostatic hypotension (or postural hypotension) is a drop in blood pressure upon standing. One definition (AAFP) calls for a systolic blood pressure decrease of at least 20 mm Hg or a diastolic blood pressure decrease of at least 10 mm Hg within 3 minutes of standing. [31]
Some specialists in severe cases give saline intravenously for hypovolemia, which, if it is the cause, brings the orthostatic hypertension down to a safe level. Pressure garments over the pelvis and the lower extremities may be used as part of treatment, due to the blood pooling issue occurring in many with the disorder. [12]
As blood is pumped through the body, the valves within the veins prevent the blood from flowing backwards. After extensive, prolonged standing, these valves can become weak and eventually fail. When this happens, blood is no longer being prevented from flowing backward. Gravity will pull the blood back into an individual's legs, ankles and feet.
Ginseng can cause abnormally low or high blood pressure and may interfere with the effects of diuretic medications. Gossypol can increase the effects of diuretics, leading to toxicity. Gynura can cause low blood pressure. Licorice can worsen heart failure by increasing blood pressure and promoting fluid retention. [54]
High blood pressure – Hypertension or elevated blood pressure can increase a person's risk of developing PAD. Similarly to PAD, there is a known association between high blood pressure and heart attacks, strokes, and abdominal aortic aneurysms. High blood pressure increases the risk of intermittent claudication, the most common symptom of PAD ...
Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...

A diagram explaining factors affecting arterial pressure. Pathophysiology is a study which explains the function of the body as it relates to diseases and conditions. The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure.
