<prompt> Decreased plasma renin activity is seen in:Primary hyperaldosteronismBaer syndromePregnancy induced HypeensionSecondary aldosteronism  <response>: Primary hyperaldosteronism is due to bilateral adrenal hyperplasia or due to adrenal adenoma. Both these conditions are autonomous and lead to aldosterone production in excess. The R.A.A.S system negative feedback will result in decrease in renin production. Low renin Hypeension is a feature of primary hyperaldosteronism.
