decrease in renin secretion

decrease in ADH secretion

Detailed explanation-1: -Hyponatremia is mediated initially by ADH-induced water retention that results in volume expansion which activities secondary natriuretic mechanisms causing sodium and water loss and restoration of euvolemia. This euvolemia should not be confused with normal water content of the body.
Detailed explanation-2: -Common situations when ADH is released into the blood when it should not be produced (inappropriate) include: Medicines, such as certain seizure drugs, antidepressants, cancer drugs, opiates (less often), and heart, diabetes, and blood pressure drugs.
Detailed explanation-3: -The role of ADH is to control water loss through the kidneys (diuresis) to maintain normal sodium levels in the blood. When sodium levels rise, ADH is secreted to limit water loss through the kidneys, resulting in very dark urine.
