Best Drinks for GLP-1 Users: Hydration Without Discomfort

Hydration plays a crucial role in feeling well during GLP-1 treatment. Medications such as Mounjaro and Wegovy can reduce thirst, slow digestion, and make large volumes of fluid uncomfortable to drink at once. Yet staying hydrated helps prevent side effects like constipation, fatigue, and headaches.

This guide explains how to meet your hydration needs safely and comfortably, with practical advice on the best drinks to choose, and which ones to avoid.

GLP-1 receptor agonists slow stomach emptying, which means fluids can sit in the stomach longer and feel heavy. Some people find fizzy or caffeinated drinks worsen nausea or bloating. Others simply forget to drink enough when their appetite and thirst decrease.

Proper hydration supports:

• Smooth digestion and bowel regularity
• Balanced energy and concentration
• Reduced nausea and headache symptoms
• Overall wellbeing during weight loss

Prioritise still fluids

Water remains the best option, but variety can make it easier to stay hydrated. Try:

• Water infused with lemon, cucumber, or mint
• Herbal teas such as chamomile, rooibos, or ginger
• Broths or clear soups for hydration with added nutrients
• Milk or fortified plant milks for extra protein and calcium

Be careful with carbonation

Fizzy drinks and sparkling water can increase bloating or nausea. If you enjoy them, try small amounts and avoid drinking alongside meals.

Limit caffeine and alcohol

Caffeine can increase reflux and dehydration, and alcohol may worsen nausea. Choose decaffeinated or alcohol-free alternatives where possible.

Watch added sugars

Juices and sweetened drinks can cause rapid blood sugar spikes. If you prefer flavour, dilute juice with water or try unsweetened options.

• Morning: Warm water with lemon or caffeine-free herbal tea
• Midday: Still water or diluted juice
• Afternoon: Broth, miso soup, or fortified plant milk
• Evening: Chamomile tea or a small glass of milk

Aim for steady intake throughout the day. You don’t need to force large amounts at once.

Speak to a Medicspot clinician if you:

• Feel consistently dizzy, light-headed, or fatigued
• Experience constipation despite fluid intake
• Find that drinking causes nausea or discomfort
• Are unsure how much fluid you need daily

A clinician can help adjust your diet or review your medication schedule to support better hydration.
