Mineralocorticoids are a class of steroid hormones produced by the adrenal glands, primarily aldosterone. They play a crucial role in regulating the balance of electrolytes, particularly sodium and potassium, in the body. By promoting sodium retention and potassium excretion in the kidneys, mineralocorticoids help maintain blood pressure and fluid balance. These hormones are essential for overall health, as they influence blood volume and pressure. An imbalance in mineralocorticoid levels can lead to conditions such as hyperaldosteronism, which can cause high blood pressure, or Addison's disease, characterized by low hormone production and resulting in various health issues.
