After prolonged fasting or vomiting, restart only when the supervising team says oral intake is appropriate and tolerance has returned. Begin with modest, familiar choices that are easy to evaluate for comfort and tolerance; progress in response to symptoms rather than trying to make up for missed food immediately.
Electrolyte disturbances can become clinically important when fluid losses or inadequate intake are substantial. The National Institute of Diabetes and Digestive and Kidney Diseases guidance on vomiting-related fluid loss notes the importance of replacing fluids and electrolytes, while severe or persistent symptoms require medical evaluation. In a peri-session setting, defer product choices, quantities, and timing to the medical team.
Report inability to keep down liquids, repeated vomiting, severe weakness, confusion, fainting, worsening abdominal symptoms, or signs that intake is not being absorbed or tolerated. These are escalation points—not reasons to layer in new foods, supplements, or home remedies.
