The Hydration
& Electrolyte Protocol

Managing delayed gastric emptying requires mechanical precision. This protocol dictates exact fluid and electrolyte timing to mitigate nausea, prevent reflux, and maintain cellular hydration.

The Gastric Emptying Mandates

The Mechanism: GLP-1 medications chemically delay the rate at which your stomach empties. High volumes of liquid, or plain water without electrolytes, will pool in the stomach, triggering the vagus nerve to induce acute nausea and reflux.

The Timelines & Rules
  • The Volume Limit (The No-Chug Mandate): Cap fluid intake at 4 to 6 ounces per 15-minute window. Chugging liquids dilates a stomach experiencing delayed motility, immediately triggering acute nausea.
  • The Meal Proximity Window: Cease all fluids 30 minutes prior to a solid meal, and do not resume drinking until 60 to 90 minutes after eating. Mixing fluids with solid food in a slowed gastric environment creates a physical backlog that causes severe bloating and pressure.
  • The Osmotic Electrolyte Ratio: Plain water can exacerbate dehydration by flushing the system. To ensure cellular hydration rather than gastric pooling, require an electrolyte baseline of at least 500mg sodium, 200mg potassium, and 60mg magnesium for every 32 ounces of water.
  • The Daily Baseline & Cutoff: Aim for 30 to 35 milliliters of fluid per kilogram of body weight daily, but front-load this volume. Cease major fluid intake 120 minutes before sleep to prevent nocturnal gastroesophageal reflux caused by stagnant stomach contents.
