Staying hydrated supports kidney health, especially for people with PKD. Drinking enough water may help slow cyst growth, flush out waste, and lower the risk of kidney stones and infections. Most adults need 2-3 litres daily, but needs vary. Try carrying a water bottle, setting reminders, or infusing water with fruit to stay on track. Sugary drinks and excess caffeine can contribute to dehydration, so water is always the best choice! Check with your doctor about the right amount for you.
