Blood value reduction

A reduction of the sodium concentration in plasma or serum below 135 mmol/l is medically called hyponatremia. Usually sodium concentrations of less than 130 mmol/l cause symptoms. Symptoms are particularly common when the sodium level drops particularly rapidly.

If it falls slowly, the body can adapt to the new sodium levels. Causes for hyponatremia can be:

  • Vomiting
  • Diarrhea
  • Kidney diseaseKidney insufficiencyNephrotic syndrome(reduced ability of the kidney to excrete sodium)
  • Drugs here are particularly the group of diuretics, which are frequently used in the treatment of high blood pressure. On the one hand, they increase water excretion via the kidneys and on the other hand, they partly increase the active excretion of sodium. The group of diuretics (water tablets) includes Furosemide (Lasix®) Chlorthalidone Thiazides But painkillers such as ibuprofen or Voltaren can also lower sodium concentrations.
  • Burns, this leads to a loss of sodium via the and wound fluid
  • Inflammation of the pancreas (pancreatitis)
  • Nicotine stimulates the above-mentioned hormone ADH, which leads to increased water and sodium reabsorption from the urine.
  • Cirrhosis of the liver
  • Heart Failure
