Patients with high blood pressure may have weakness of limbs. First of all, high blood pressure may cause cerebrovascular complications, such as stroke, etc. Patients with stroke will have hemiplegia of one side of the limbs and weakness of limbs. In addition, for patients with high blood pressure, if it is secondary hypertension, such as primary aldosteronism, there is often low potassium in the blood, which can cause weakness in the limbs. In addition, high blood pressure can cause episodes of dizziness, chest tightness, palpitations, and other symptoms, and when symptoms flare up, they may also cause weakness in the extremities. For high blood pressure combined with limb weakness, electrolyte-related examination is needed, and cranial imaging examination is needed to clarify the occurrence of electrolyte disorders and cerebrovascular diseases, and to carry out systematic diagnosis and treatment.
