Is 111/43 BP too low? female 76 age

Answer 1

Blood pressure readings are expressed in millimeters of mercury. This unit is abbreviated as mm Hg. A normal reading would be any blood pressure below 120/80 mm Hg and above 90/60 mm Hg in an adult. 

Pulse pressure is the difference between systolic and diastolic blood pressure. Your pulse pressure is very high. The most important cause of elevated pulse pressure is stiffness and reduced elasticity of the aorta, the largest artery in the body. This may be due to high blood pressure or fatty deposits on the walls of the arteries (atherosclerosis). Do you have any discomfort?

Answer 2

Blood pressure readings will differ according to when they were taken (right after eating, excercise, etc.), which arm they are taken from, whether you were sitting or standing, if the machine used is calibrated right and all sorts of other factors. If this blood pressure reading is correct you are waaaaay over on your bottom reading. The top number is the pressure exerted from your heart when it beats, the bottom number is the pressure in your heart when it is at rest.The bottom is a little low, but not the end of the world. If you are really worried about it, check it again. Or ask your doctor what he or she thinks or recomends. But your height, weight, age and health history matter. Otherwise in "general" it is not a bad BP.
