How much water should I drink, and do I need electrolytes?

Aim for about 8 to 12 cups of fluids a day (64 to 96 oz, or about 2 to 3 liters), spread through the day. Drink more in hot weather, when you exercise, and when you are losing fluid from vomiting or diarrhea. Staying hydrated supports digestion, helps with side effects like constipation and nausea, and keeps your energy up. That matters more on a GLP-1, because you may eat and drink less without noticing.

A quick self-check: pale-yellow urine and steady energy usually mean you're drinking enough. You don't have to hit an exact ounce target.

If a provider has told you to limit fluids (for example for heart failure or kidney disease), follow their limit instead.

What to drink

• Water (still or sparkling), unsweetened tea, herbal tea and broth.
• Coffee and tea in moderation are fine. Add an extra glass of water for each caffeinated drink.
• Food counts too: broth-based soups, yogurt, and water-rich produce like cucumber, melon and oranges.

What to limit: alcohol (it can worsen nausea and reflux), sugar-sweetened drinks, and high-caffeine energy drinks.

A simple daily routine

• Morning: 12 to 16 oz of water within 30 minutes of waking.
• Before meals: a small glass 10 to 15 minutes before you eat.
• Through the day: keep a 20 to 24 oz bottle nearby and refill it 2 to 3 times. A phone reminder every 60 to 90 minutes helps some people.

When side effects hit

• Nausea: take small sips often, and try ginger or peppermint tea. Don't chug.
• Constipation: pair fluids with fiber and a daily walk.
• Reflux: sip between meals rather than during them, and limit late-night drinks.

Do I need electrolytes?

Most people get enough sodium from food. Electrolytes help most when you're losing fluid faster than usual:

• Use a sugar-free, sodium-forward electrolyte drink when you're sweating heavily, it's hot, you're at altitude or traveling, you feel lightheaded or crampy, or you've had vomiting or diarrhea. HydroBelle is one option.
• For ongoing vomiting or diarrhea, an oral rehydration solution (like Pedialyte or a pharmacy ORS) works better than a sugar-free drink: the small amount of sugar helps your gut absorb the sodium and water. If you can't keep fluids down, contact your care team.
• Check with your provider first if you have high blood pressure, kidney or heart disease, or take blood-pressure medicines or diuretics. Some electrolyte products are high in sodium, potassium or magnesium.
