Primary aldosteronism (PA) is occasionally associated with impaired glucose tolerance.Glucose intolerance, in general metabolic syndrome is caused by suppression of insulin release from the pancreas and suppression of insulin sensitivity of the target tissues.Several studies have suggested that impaired glucose tolerance in primary aldosteronism is due to an inability of the beta cells to release insulin by potassium depletion. It was suggested glucose intolerance in PA is caused by the suppression of insulin release related to hypopotassemia and compensatory increase of insulin sensitivity is observed in PA. The increased insulin secretory capacity associated with correction of negative potassium balance may account for the increase in plasma leptin after curing primary aldosteronism. The conclusion with respect to the possible causal relationship between diabetes mellitus (DM)and PA, however, can be obtained after the evaluation of the effect of surgical/pharmacological treatment of PA.
