👉 Hunger fluid, also known as oral rehydration solution (ORS), is a specially formulated mixture designed to rapidly replenish fluids and electrolytes lost through dehydration, primarily in individuals suffering from severe diarrhea or vomiting. Composed of water, sugar (usually glucose), sodium, and sometimes potassium, this solution works by enhancing the absorption of water and electrolytes in the small intestine through a process called cotransport. The added glucose helps drive sodium absorption, which in turn facilitates the reabsorption of water, effectively reversing dehydration and restoring hydration levels. It is a critical component in the management of dehydration, especially in emergency situations and among vulnerable populations such as children.
