A hypertensive emergency with acute visual impairment due to excessive liquorice consumption.
Hypokalaemic hypertension is the classical presentation of primary hyperaldosteronism but may also result from other mineralocorticoid activity, such as liquorice ingestion. Onset of hypertension as well as serum renin and aldosterone levels are central for the diagnosis. Liquorice ingestion has been reported to induce hypertension, hypokalaemia and metabolic alkalosis due to inhibition of the enzyme 11-β-hydroxy steroiddehydrogenase 2. Here, we report the case of a hypertensive emergency with acute visual impairment due to hypertensive retinopathy in clear conjunction with a considerable consumption of liquorice.
