Taking antihypertensive drugs with soft feet may be caused by low blood pressure due to overdose, or electrolyte disorders such as hypokalemia and other causes. 1. Overdose: If the dosage of oral antihypertensive drugs is too much, it may cause low blood pressure, reduced perfusion of blood flow to the brain and other peripheral blood vessels, and insufficient blood supply, which may result in dizziness, weak feet and other symptoms. 2. Electrolyte disorders: If the antihypertensive drugs used are diuretics, such as hydrochlorothiazide, etc., prolonged use will easily induce hypokalemia, which will lead to numbness of the limbs, weakness and other manifestations, and in serious cases, it will also lead to cardiac arrhythmia and tachycardia. If high blood pressure has been detected, you should consult a doctor in time and analyze the causes of weakness and aching under the guidance of a professional doctor, and then target treatment according to the diagnosis.
