To manage loose motion and vomiting, your absolute priority is preventing dehydration. Start drinking Oral Rehydration Salts (ORS) solution, coconut water, or clear fluids in small, frequent sips. For vomiting, an over-the-counter antiemetic like Ondansetron can help, and probiotics can support gut recovery. Avoid taking anti-diarrheal medications (like Loperamide) if you have a fever or bloody stools, as this can worsen certain infections. Stick to a bland diet like bananas, rice, and toast. If you cannot keep fluids down, have a high fever, or experience severe abdominal pain, please consult a doctor immediately for a physical evaluation.
