Can you have shortness of breath due to high blood pressure?
When the blood pressure rises gradually, the heart gets accustomed to it by increasing the thickness of the left ventricle so that it can easily overcome the high blood pressure and still pump enough blood to the rest of the body. But when there is a rapid rise in the blood pressures as in acute kidney injury, the heart does not get enough time to adapt to the high work load and it may fail. When the heart fails, blood dams up in the lungs causing fluid to collect in the tiny air passages (pulmonary edema) causing shortness of breath. Even in a gradual increase of blood pressure, the heart can fail when the blood pressure becomes extremely high. Shortness of breath can occur in that situation as well.
