Primary aldosteronism (PA) is considered the most common form of endocrine hypertension, accounting for 4%–10% of hypertension cases (Sodium in diet is mainly derived from NaCl (salt) and is essential for cellular homeostasis and body function. One gram of sodium is contained in ~2.5 g of salt, and almost 90% of sodium in the diet comes from table salt. Both the World Health Organization (WHO) (Aldosterone excess has a marked effect on taste perception. A prospective study found that NaCl taste perception was significantly impaired in patients with PA, which evidenced a NaCl taste recognition threshold about twice as high as that observed in essential hypertension (Reducing sodium intake in essential hypertensive patients has been shown to lower blood pressure (BP) (A reduction in sodium intake is usually followed by a drop in blood volume, which activates the renin-angiotensin-aldosterone system (RAAS) (The current guidelines for PA do not specify a recommended intake of sodium, and the effect of reduced sodium intake on PA is unclear. Based on this, and the above considerations, the goal of this study was to investigate the effect of a low-sodium diet on IHA and to provide a useful reference for clinical practice.
