Table 2

Sodium retention can be achieved by a variety of causes.

(i) Excess intake of sodium; essential hypertension
(ii) Impaired renal excretion
 (a) Renal insufficiency and renal failure
  (b) Insulin resistance accompanied by obesity and/or the early stage of type II diabetes mellitus
  (c) Increased aldosterone production; primary aldosteronism, idiopathic hyperaldosteronism, renovascular hypertension,
  pheochromocytoma
  (d) Other mineralocorticoid excess; 17a-hydroxylase deficiency, 11b-hydroxylase deficiency, apparent mineralocorticoid
  excess syndrome and deoxycorticosterone-producing tumor
  (e) Exaggerated renal sodium reabsorption; Liddle syndrome
