GLP-1 appetite suppression often masks thirst. Electrolyte powders that actually replace what you lose.
About 60% of GLP-1 patients report inadequate hydration in their first 90 days — often confused with constipation or fatigue.
Dehydration is the most underestimated GLP-1 side effect. Appetite suppression dampens thirst signals. Reduced caloric intake also reduces water intake — most people get 20-30% of daily fluid from food. Combined with GI side effects (vomiting, diarrhea), patients can drop 2-3% body water within days.
Acute kidney injury during GLP-1 titration is almost always dehydration-driven. Sodium, potassium, and magnesium losses through GI side effects compound the problem. Electrolyte powders work better than plain water — sodium is needed to pull water into cells, and most patients are already low.
When to seek medical advice (not OTC)
Seek medical care for: persistent dizziness, dark urine for 24+ hours, rising creatinine on lab panel, inability to keep fluids down for 12+ hours, or fainting. AKI from dehydration is reversible if caught early.
LMNT
1000mg sodium + 200mg potassium + 60mg magnesium per packet. The high-sodium ratio actually matches what GLP-1 patients lose during titration GI episodes.
Liquid I.V.
Lower sodium (500mg) + glucose for absorption. Widely available retail. Suitable for normotensive patients.
DripDrop
Medical-grade ORS (oral rehydration solution). Sugar-free with stevia. Developed by physicians for acute dehydration.
Cure Hydration
Coconut water base + pink Himalayan salt. No sugar. Lower sodium (220mg) — best for those who already have hypertension under control.
Nuun
Tablet form (dissolve in water). 360mg sodium + 100mg potassium. Travel-friendly, no powder mess.
Minimum 64 oz (2L) baseline plus 8-12 oz per hour during titration weeks. Add 16-24 oz for every vomiting/diarrhea episode. Watch urine color — pale yellow target.
Sodium is needed to pull water into cells. Plain water can't replace what GI side effects strip. Patients who drink only water during titration often develop hyponatremia (low sodium) which causes dizziness + confusion.
Yes. Choose lower-sodium options (Cure 220mg, Nuun 360mg). Or pre-load sodium before GLP-1 injection days only, returning to baseline diet rest of week. Discuss with prescriber.
