It is not always the case that how high the blood pressure is will cause kidney damage. Kidney damage caused by hypertension is related to the duration of hypertension, the level of blood pressure, and whether it is combined with other kidney diseases. Kidney damage caused by high blood pressure depends on whether the blood pressure is well controlled or not, and has little to do with the size of the high blood pressure. If blood pressure is controlled at a normal level with antihypertensive medication, it usually does not cause serious kidney damage. However, if you have high blood pressure but it is poorly controlled over a long period of time, it can easily lead to kidney injury. Kidney damage caused by high blood pressure is mostly due to long-term poor blood pressure control. Even if the systolic blood pressure exceeds 180mmHg for a short period of time, treatment to control the blood pressure to a normal level may not necessarily cause kidney injury. If you have high blood pressure or kidney injury, you should consult a doctor in time and take active treatment under the guidance of a physician.
