Hypertension can be divided into primary and secondary. The endocrine causes of hypertension are primary aldosteronism, Cushing's syndrome, pheochromocytoma, acromegaly, hypo/hyperthyroidism etc. They are classed as secondary hypertension. Although they account for only a small part of the overall prevalence of hypertension it is very important to diagnose them because they are potentally curable. The best treatment approach for endocrine hypertension is treating its cause (endocrine pathology), especially by surgery. Primary aldosteronism is the most common form with prevalence of 5-13% in hypertensive patients. It is a group of disorders characterized by excessive aldosterone secretion, hypertension, hypokalemia, hypernatremia and metabolic acidosis. Aldosterone hypersecretion induces hypertension by affecting several organ systems. Laparoscopic removal of adenoma or entire gland represents the elective treatment in unilateral PA variants. Patients with bilateral autonomous aldosterone production should be treated with mineralocorticoid receptor blockers. Cushing's syndrome is characterized by excessive secretion of hormones produced in the adrenal cortex. Characteristic symptoms of hypercortisolism are stretch marks, skin atrophy, moon face and proximal muscle weakness. The etiology of arterial hypertension is complex and it occurs in approximately 80% of patients with Cushing's syndrome. Pheochromocytomas are rare catecholamine-secreting tumors. The classic triad of symptoms consist of headaches, excessive sweating and palpitations. One third of patients have paroxysmal hypertension, half have persistent, and others may be normotensive. Surgical resection of the tumor is the treatment of choice. Careful preoperative management is required to control blood pressure and prevent intraoperative hypertensive crises. Acromegaly is a rare cause of hypertension, it is a chronic disease characterized by excessive secretion of growth hormone. Hypertension occurs in 40% of patients with predominantly elevated diastolic pressure.
