Mild cases of hypertension do not cause generalized weakness, but if the patient’s hypertension lasts for a long time and the relative target organ function is impaired, it can lead to generalized weakness. If the patient takes certain antihypertensive drugs for a long period of time, the antihypertensive drugs may also cause the side effect of generalized weakness, such as taking diuretics as antihypertensive drugs and not paying attention to potassium supplementation when taking them for a long period of time, which may lead to generalized weakness due to hypokalemia. In addition, if a patient with hypertension has impaired target organ function, such as cerebrovascular insufficiency of blood supply, the patient may experience dizziness, headache, tinnitus, drowsiness, fatigue, weakness and lethargy, and even blurred vision, all of which are comorbidities of target organ damage after hypertension.
