Repeated vomiting, where even water does not stay in the stomach, can quickly lead to dehydration and weakness, especially if it has been continuing for several hours. Granirex may help reduce nausea and vomiting, but if symptoms continue despite taking it, the underlying problem may still be active. Vomiting can happen because of stomach infection, food poisoning, acidity, viral illness, migraine, or digestive irritation. Instead of giving large amounts of water at once, try giving very small sips of oral rehydration solution, clear fluids, or electrolyte drinks slowly every few minutes. Heavy meals, oily foods, milk products, and spicy foods should be avoided until the stomach settles. Resting and avoiding sudden movement may also help reduce nausea. Persistent vomiting may require medical reassessment because dehydration can develop even without diarrhoea. Dry mouth, dizziness, reduced urination, excessive weakness, or inability to tolerate any fluids are important warning signs. Seek medical attention soon if vomiting continues repeatedly, severe abdominal pain develops, fever appears, blood is seen in vomit, or she becomes unusually weak or drowsy.
