Addison's disease is a disorder where the body produces insufficient amounts of certain hormones produced by adrenal glands. One of the hormones affected, aldosterone, helps regulate sodium and potassium levels in the body. In Addison's disease, aldosterone production is decreased, causing a decrease in blood pressure, arrhythmias, increased heart rate, and low sodium, potassium, and chloride levels.

This condition causes excessive production of aldosterone by the adrenal glands, which would typically lead to high blood pressure and low potassium levels, not low blood pressure and low sodium, potassium, and chloride levels.

This tumor, found in the adrenal glands, produces too much adrenaline and noradrenaline, causing high blood pressure, headaches, heavy sweating, rapid heartbeat, and anxiety. It does not typically cause low levels of sodium, potassium, and chloride.

This condition is characterized by high levels of cortisol, causing obesity, muscle weakness, fatigue, and high blood pressure, but not typically low sodium, potassium, and chloride levels.
