Please please please correct me if I'm wrong... Tell me what illness causes these.





-cold clammy extremities and muscular weakness


-lowered blood pressure


-weak and rapid pulse


-skin discoloration


-Urine analysis showed the urine density was 1.009 g/ml and a significant lowering in the plasma sodium level in the blood.

Is this symptoms a cause of hyponatremia?
generally symptomatic hyponatremia is associated with a rapid decrease in plasma sodium to %26lt;125 mmol/L. Symptoms become increasingly severe as the levels drop further. Usually the symptoms include headache, vomiting, swollen hands and feet, fatigue and wheezy breathing. So it is possible but based on the info given I can't say for sure
