Dehydration, or the excess loss of fluids and electrolytes from the body, can occur for many reasons. It includes prolonged heat exposure and strenuous exercise, inadequate fluid intake, fever and vomiting. However, diarrhoea remains one of the most important causes of the condition, particularly in children.
Step-by-Step Instructions
This absorption mechanism continues to work during most episodes of acute diarrhoea, allowing ORS to replace the water and salts being lost in stools.” In the words of Dr Kalra, “For diarrhoeal dehydration, WHO-approved ORS is the gold-standard first-line treatment. ORS contains sugar and electrolytes in carefully determined proportions. Glucose helps the intestine absorb sodium, and water follows.
“Infants or children are more vulnerable to diarrheal dehydration due to their higher body water composition, faster metabolic rates, and inability to communicate their thirst or get fluids independently,” noted Dr Kalra, warning that the condition becomes worse when coupled with vomiting.
