Dizziness and headache caused by high renin activity should be firstly clarified and then treated for the cause. It is considered to be related to emotional excitement, renal artery stenosis, adrenal tumor and other factors. Such as adrenal tumor, surgical treatment can be taken. 1. Emotional excitement: emotional excitement or mental tension in human body can lead to sympathetic nerve excitement, which will result in elevated renin level. 2. Renal artery stenosis: Renal artery stenosis can lead to elevated renin. Blood flow through the kidneys decreases when the renal artery is narrowed, thus stimulating the kidneys to produce more renin. The goals of treatment are to control blood pressure, protect renal function, and reduce cardiovascular complications. If necessary, revascularization is performed. If the phenomenon of dizziness and headache caused by high renin activity occurs, it can be treated in time after further examination in the hospital to clarify the cause. Daily life should pay attention to rest and appropriate exercise.
