Dåligt blodtryck symptom
Definitionen av lågt blodtryck är ett blodtryck under 90/60 mmHG med symtom. Vanliga symtom är trötthet, yrsel och i vissa fall avsvimning. Om du inte har några symtom anses inte ditt blodtryck vara för lågt, oavsett värdet. I motsats till högt blodtryck som behandlas utan symtom så behandlas inte lågt blodtryck utan symtom. Low blood pressure is a condition in which the force of the blood pushing against the artery walls is too low.
It's also called hypotension.
Blood pressure is measured in millimeters of mercury mm Hg. What's considered low blood pressure for one person might be OK for someone else though. Low blood pressure might cause no symptoms that you notice. Or it might cause dizziness and fainting. Sometimes, low blood pressure can be life-threatening. The causes of low blood pressure include dehydration and other serious medical conditions. It's important to find out what's causing low blood pressure so that it can be treated, if needed.
For some people, low blood pressure may be a symptom of an underlying health condition. That's especially so when blood pressure drops suddenly or when low blood pressure occurs with symptoms.
Lågt blodtryck: varför uppstår det, vilka symtom har det? + Komplikationer
A sudden fall in blood pressure can be dangerous. A change of just 20 mm Hg can make you feel dizzy or faint. For example, those symptoms could happen after a drop in systolic pressure from mm Hg to 90 mm Hg. And big drops can be life-threatening. These can happen for reasons such as serious bleeding, serious infections or allergic reactions. If you have symptoms of extreme low blood pressure or shock, call or your local emergency number.
Most healthcare professionals consider blood pressure to be too low only if it causes symptoms. Minor dizzy or lightheaded feelings from time to time can be caused by many things. Causes could include spending too much time in the sun or in a hot tub. It's important to see a healthcare professional to find out the cause of your symptoms. If you often have low blood pressure readings but feel fine, you might not need treatment.
