Water poisoning

Water poisoning means that the body intakes or inputs too much water, so that water is retained in the body, causing blood osmotic pressure to decrease and circulating blood volume to increase, also known as dilute hyponatremia. Water poisoning occurs less frequently. Only in the case of excessive secretion of antidiuretic hormone or renal insufficiency, the body intakes too much water or receives too much intravenous fluids, which causes water to accumulate in the body, resulting in water poisoning.
