GLP-1 medicines can impact your hydration needs. These medications often result in gastrointestinal side effects such as nausea, vomiting, or diarrhea, which can lead to fluid loss. It's essential to stay well-hydrated to counter these effects. Drinking plenty of water and consuming hydrating foods can help maintain your fluid balance. If you notice any signs of dehydration, like dizziness or dark urine, it’s crucial to consult your healthcare provider. They can guide you on managing hydration while on GLP-1 treatment, ensuring you remain comfortable and healthy throughout your therapy.
