High blood pressure
Blood pressure is measured often because it has important effects on the heart and circulation, and because nowadays high blood pressure side effects(also called hypertension) can be easily treated.
The kidneys have a major influence on blood pressure and it is particularly important to monitor blood pressure whenever kidney disease is suspected. There are three reasons for this:
Many kidney diseases cause high blood pressure - high blood pressure is very common in people with kidney diseases
High blood pressure can cause further damage to diseased kidneys
People with kidney disease are at high risk of developing heart disease and circulation problems
What trouble does high blood pressure cause?
High blood pressure rarely produces any symptoms at all, unless it is very high. However people with high blood pressure have more strokes and heart attacks than people with normal blood pressures, and it may damage kidneys. How often high blood pressure damages normal kidneys is uncertain, but it is probably quite rare compared to the heart disease and strokes that it causes. Kidney damage caused by blood pressure seems to be more common in some races, particularly in black people.
Rarely, very severe what is blood pressure may cause serious damage much more quickly - over days and weeks, rather than months and years. This is called 'accelerated phase', or 'malignant' hypertension, and it usually causes a severe illness requiring hospital admission. Fortunately very few people (even with kidney disease) get this condition. More information about malignant hypertension (accelerated phase hypertension).
