In the early stages of hypertension, there are usually no obvious conscious symptoms, and many patients do not even know that their blood pressure is high, and only find out that it is elevated during physical examinations or occasional blood pressure tests. Hypertension only causes corresponding symptoms when it involves the heart, brain, kidneys, fundus and other organs. Hypertension can cause damage and clinical complications to the heart, brain, kidneys, systemic blood vessels, fundus and other important organs, and many patients are only aware of their high blood pressure when they have a heart attack, stroke or kidney failure and need dialysis. Therefore, hypertension is called the “silent killer”. Therefore, regular medical checkups are an important way to detect hypertension. It is recommended that adults with normal blood pressure have their blood pressure measured at least once every two years, and those who are prone to hypertension have their blood pressure measured at least once every six months. Symptoms may occur when hypertension progresses to affect the heart, brain, kidneys, fundus and other organs. If the brain is affected, dizziness, headache, blurred vision, tinnitus, insomnia, memory loss, weakness or paralysis of the limbs, etc.; when the heart is affected, palpitations, shortness of breath, chest tightness, etc. can occur. Affecting the kidneys can appear as increased nocturia? Foamy urine and other symptoms. In addition, when hypertension affects the arteries of the fundus of the eye, symptoms such as bleeding from the fundus of the eye may occur. Once the complications of hypertension occur, they can be life-threatening and affect the quality of life, so they should be detected and treated early.
