Hydration
Deliberate fluid intake — the most neglected variable on appetite-suppressing medication.
Most daily fluid arrives by habit — with meals, through food itself — and GLP-1 therapy quietly cuts both channels while its GI side effects raise losses. The result is the most common invisible problem in treatment: low-grade dehydration presenting as fatigue, headaches, dizziness, constipation, and sluggish weight trends, occasionally escalating to the kidney territory labels warn about.
The fix is unsophisticated by design: a bottle with a known volume, refilled on schedule, targeting pale-yellow urine rather than a universal liter count; electrolytes added during vomiting or diarrhea spells, heat, or heavy exercise. Water also moonlights as appetite hygiene — thirst masquerades as hunger often enough that drinking first is a legitimate craving check.
