Since she has been fasting, her stomach is highly sensitive. The immediate priority is preventing dehydration. Start her on Oral Rehydration Salts (ORS) or coconut water, taken in small, frequent sips. Avoid solid foods for a few hours. For nausea, an over-the-counter antiemetic like Ondansetron can help, but consult a doctor first. Avoid taking anti-diarrheal medications (like Loperamide) immediately without medical advice, as they can worsen certain infections. Once vomiting stops, introduce bland foods like rice or bananas. If she cannot keep fluids down, has a high fever, or experiences severe pain, please seek immediate medical attention.

Right upper abdominal pain with loose stools and early blood in stool is more likely due to gastritis or a gut infection, whereas small stones usually cause pain after fatty meals and do not cause loose stools or blood. Eat light food, avoid oily and spicy items, stay hydrated, and take proper rest to help the stomach heal. Notice if pain increases after meals or is constant, and avoid triggers that worsen it. Since both conditions are present, consult a doctor to review reports and confirm the cause for proper treatment.
