Diarrhea means the fluids you consume get ejected before your body can absorb them. Your body needs to regularly replenish fluids in order to operate.
Victims of Cholera for example eventually die of *dehydration* due to constant vomiting and the diarrhea.
Injecting saline directly into your bloodstream bypasses your digestive system and allows your body to stay alive even *if* it is suffering from diarrhea and vomiting.
