Vad orsakar hypotension?
Lågt blodtryck är vanligt och ofta åldersrelaterat. Vätskebrist eller saltbrist kan sänka blodtrycket. Andra orsaker kan vara hjärtsjukdom till exempel nedsatt pumpfunktion, som vid hjärtsvikt eller neurologisk sjukdom, till exempel Parkinsons sjukdom.
Hur vanligt är lågt blodtryck?
Lågt blodtryck är vanligare bland unga, långa och smala personer. Blodtrycket varierar från person till person. Lågt blodtryck kallas även hypotension eller hypotoni. Blodtrycket är inte konstant utan varierar under dygnet, mellan olika dagar och mellan olika perioder i livet.
What are the symptoms of postprandial hypotension in the elderly?
Postprandial hypotension can cause dizziness, light-headedness, faintness, and falls. If an older person experiences these symptoms after eating, doctors measure blood pressure before and after meals to determine if postprandial hypotension is the cause. Adjust drug timing and activities around meals.
What is postprandial hypotension and why is it dangerous?
Blood flows normally to the intestine, but the heart rate does not increase adequately and blood vessels do not constrict enough to maintain blood pressure. As a result, blood pressure falls. Postprandial hypotension can cause dizziness, light-headedness, faintness, and falls.
What is the best treatment for postprandial hypotension?
Treatment. People who have symptoms of postprandial hypotension should not take antihypertensive drugs before meals and should lie down after meals. Taking a smaller dose of the antihypertensive drugs and eating small, low-carbohydrate meals more frequently may help reduce the effects of this disorder.
Can Postprandial hypotension be detected by blood pressure monitoring?
Postprandial hypotension is easily detectable by manual or automatic blood pressure measurements. Ambulatory blood pressure monitoring is a valuable and useful method to investigate meal-related blood pressure changes in elderly patients ( 9, 14 ). Only a few studies have used ambulatory blood pressure monitoring.
