GPMD Podcast- Kids’ Hydration Off the Shelf

Join Nurse KC and Dr. Beth as they break down when adult electrolyte packets like Liquid IV can be used for children, and when pediatric oral rehydration solutions like Pedialyte are required. They explain age-based recommendations, dilution and dosing tips, differences between sports hydration and illness rehydration, and practical steps for what to buy and how to mix it. Key takeaways: water-first for everyday hydration; Pedialyte (or generic ORS) for vomiting/diarrhea; diluted adult packets may be reasonable for healthy kids 4+ during sports; never use energy drinks for kids; and seek care for severe dehydration signs.

GPMD Podcast—Hot Take Summer 2026: Why a Stick Pack Isn’t a Hydration Plan

Summer 2026 is poised to be unusually hot, and this episode explains how heat changes physiology—sweat, sodium loss, blood flow shifts, and gut tolerance—and why one-off hydration packets don’t automatically meet your needs. Learn to choose hydration by purpose (daily maintenance, sweat replacement, heat/performance, illness, kids, or older adults), understand why mixing ratios and ingredients matter, and why pediatric and oral rehydration solutions differ from trendy stick packs. This episode breaks down Liquid IV as an example of different formulations for different jobs, emphasizes age and medical context, and offers practical, gut-smart tips: pick the job first, the formula second, and the flavor last.

GPMD Podcast— How Do You Hydrate Your Brain?

In this episode Nurse KC and Dr. Beth explain how brain hydration depends on stable blood flow, sodium balance, osmolality, and cell volume — and why the gut is essential because it absorbs the fluids and electrolytes that enter circulation. They cover common dehydration symptoms, why drinking more water isn't always the answer, and practical takeaways: balance fluids and electrolytes, consider gut absorption, and seek medical care for severe or new neurological symptoms.
