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.
