    • Kidney disease (abnormalities),
    • Tumors of the adrenal gland,
    • Endocrine disease (hormone disorders; a hormone is a regulatory chemical that occurs naturally in your body),
    • A narrowing of the aorta (the largest artery leading from the heart) or the arteries leading to the kidneys,
    • Certain medications, such as contraceptive pill, cold remedies, decongestants, over-the-counter pain relievers and some prescription drugsIllegal drugs, such as cocaine and amphetamines,
