It is more dangerous to have diarrhea more than a dozen times a day, which can lead to electrolyte disorders in the human body, showing symptoms such as general weakness and lack of energy, and can even be life-threatening. Frequent diarrhea must be taken seriously, because diarrhea can lead to the loss of a large amount of water in the body, causing the body’s resistance to reduce, affecting the absorption of water in the body. When the body’s water content is less than 50% of body weight and exceeds the body’s ability to compensate, a series of disorders of water, electrolytes and acid-base balance may occur, such as hyperkalemia and hypocalcemia, and severe dehydration may lead to insufficient effective blood volume and cause shock. In the case of diarrhea, or must pay attention to drink more water. A rehydration solution containing potassium chloride, sodium chloride and glucose is the ideal choice to replenish the glucose and minerals lost in the body, as well as to regulate water and ensure acid-base balance.
