Question 1

How much water should I drink each day?

Accepted Answer

A common baseline is half your body weight in ounces (e.g., 160 lbs = 80 oz). Needs increase with exercise, hot weather, high protein intake, and certain medications. This calculator provides a personalized target.

Question 2

Why is hydration important on GLP-1 therapy?

Accepted Answer

GLP-1 medications slow digestion and reduce appetite, which often reduces overall fluid intake. Staying well hydrated helps prevent the most common side effects — constipation, fatigue, and headaches.

Question 3

Does coffee or tea count toward my water intake?

Accepted Answer

Yes. Despite their mild diuretic effect, coffee and tea contribute meaningfully to total daily hydration. Plain water should still make up the majority of your intake.

Question 4

Can I drink too much water?

Accepted Answer

In rare cases, drinking extreme amounts of water in a short period can cause hyponatremia (low sodium). For healthy adults, spacing water throughout the day and drinking to thirst is safe and effective.

Question 5

What are signs I'm not drinking enough?

Accepted Answer

Dark yellow urine, infrequent urination, dry mouth, headaches, fatigue, dizziness, and constipation are common early signs of dehydration. Pale-yellow urine is a good daily indicator of healthy hydration.
