History

Conn's syndrome (primary hyperaldosteronism) may be suspected in the following scenarios:

• Patients with a history of spontaneous or unprovoked hypokalemia along with hypertension.
• Patients who develop severe and/or persistent hypokalemia while on low to moderate doses of potassium-wasting diuretics.
• Patients with a history of treatment-refractory/-resistant hypertension (HTN).

Patients with profound hypokalemia report fatigue, muscle weakness, cramping, headaches, and palpitations. They can also have polydipsia and polyuria from hypokalemia-induced nephrogenic diabetes insipidus. Long-standing HTN may lead to cardiac, retinal, renal, and neurologic problems, with all the associated symptoms and signs. Patients with conn's syndrome(primary aldosteronism) may have subclinical systolic dysfunction, lower heart rates, higher blood pressure and vascular resistance values than those with the secondary hyperaldosteronism. Plasma renin activity has been found to be lower in primary than in secondary hyperaldosteronism.

Hypokalemia related symptoms

• Constipation
