High blood pressure causes headaches in most patients. Headaches and dizziness are the most common symptoms of fluctuations in blood pressure. Most patients will experience headache, dizziness, head swelling, tinnitus, palpitations, accompanied by poor sleep quality and emotional irritability in the early stages of elevated blood pressure. If patients are treated in time to control the rise of blood pressure, it can effectively stabilize blood pressure and make it avoid the occurrence of target organ damage, such as kidney damage, which can induce hypertensive nephropathy in the case of long-term hypertension, and brain damage, which can easily induce cerebral hemorrhage in the case of sustained hypertension in the brain. Therefore, when hypertension occurs early, it is recommended to visit the cardiology department of the hospital and monitor 24-hour ambulatory blood pressure to facilitate the diagnosis. Patients diagnosed with hypertension are advised to follow the doctor’s prescription for continuous medication and not to easily adjust the medication or stop it on their own to avoid a rapid rise in blood pressure within a short period of time or the occurrence of hypertensive crisis, angina pectoris, heart attack, brain infarction and other adverse conditions.
