Hyponatremia occurs when serum sodium is less than 135 mmol/L. Hyponatremia is triggered by renal disease, which is caused by excessive sodium loss due to electrolyte disorders, use of medications, and so on.
1. Kidney diseases are wide-ranging, such as nephrotic syndrome, which causes a decrease in osmolality due to the loss of protein in the body. Thereby, water and sodium in the blood vessels will enter into the crevices of the body tissues, causing the water and sodium in the blood vessels to become less in the blood vessels, which eventually triggers hyponatremia.
2. It is caused by hormonal drugs used in the treatment of nephropathy. For example, nephrotic syndrome is treated with adrenocorticotropic hormone for a long period of time, which suppresses the function of adrenal cortex. If the corticosteroid is discontinued, there will be a secondary decrease in cortical function, which will also cause hyponatremia.
Hyponatremia caused by nephropathy can also be seen in other causes, and it is recommended that patients go to the hospital in time, follow the doctor’s instructions for relevant examinations, clarify the cause with the help of the doctor, and carry out targeted treatment or therapy.
