Reduced extracellular fluid

The loss of human body fluids causes a decrease in extracellular fluid, which is called dehydration. When people work under high temperature conditions, strenuous exercise or some diseases (such as severe vomiting, severe diarrhea), they will lose a lot of water and inorganic salts (mainly sodium salts), which will cause the body's extracellular fluid osmotic pressure The symptoms such as decreased blood pressure, increased heart rate, and four chills were severe, and even severely comatose.
