Yes. : They lesions or diseases often are accompanied by high bp. There are kidney tubule defects or hormonal disturbances related to the adrenal gland function that can cause low potassium yet lab testing show normal kidney function in terms of clearance. Also medications and herbal supplements (including even exotic type of tea, licorice, or some tobaccos) can cause potassium disturbances.
