Calling out the “common belief” that taking blood pressure medicines daily can harm the kidneys, Dr Parin Sangoi, a consultant interventional cardiologist at Wockhardt Hospitals, Mumbai Central, stressed that this is “not correct.” “Blood pressure medicines do not damage the kidneys. In fact, untreated high blood pressure is a major cause of kidney disease. When blood pressure remains elevated for extended periods, it damages the small blood vessels in the kidneys, gradually reducing their ability to filter waste. This often happens quietly and may go unnoticed for years,” Dr Sangoi told indianexpress.com.

The cardiologist clarified that in many cases, kidney damage has already begun by the time high blood pressure is found. “Once treatment starts and blood pressure is controlled, routine tests may reveal existing kidney issues. This timing can lead people to wrongly blame the medicines when the damage was actually caused by long-term untreated hypertension,” said Dr Sangoi.
