With Wegovy use on the rise, more and more people are achieving the rapid weight loss results they once wished for. However, what many overlook is the equal importance of staying properly hydrated while using GLP-1 medications.
Wegovy is a once-weekly injection that reduces feelings of hunger and thirst, helping you feel full for longer. As a result, you may naturally consume less food and water, which can lead to dehydration.
Let’s explore how dehydration can impact healthy weight loss and some hydration tips to follow on Wegovy .
Why is Hydration Important on Wegovy?
Hydration plays a direct role in how well your body responds to Wegovy and how effectively you lose weight. When you’re properly hydrated, your metabolism functions more efficiently, helping your body burn calories and absorb nutrients. Adequate water intake also allows your GLP-1 medication to circulate smoothly through the bloodstream and reach its target sites effectively.
Staying hydrated also makes your weight loss journey smoother and more comfortable. In the SURMOUNT-1 trials, individuals who received tirzepatide reported gastrointestinal side effects such as nausea, vomiting, and constipation. Proper hydration can help manage these symptoms and make treatment easier to tolerate.
What if I Am Not Properly Hydrated on Wegovy?
When you don’t consume enough fluids on Wegovy, your body can experience both short-term and long-term effects. Here are some of the most common ones:
Short-Term Impact on Health and Progress
Tiredness and low energy: Even mild dehydration can cause fatigue and make your body feel sluggish, especially when you’re eating less.
Dull headaches or dizziness: Reduced fluid levels affect blood pressure and brain function, leading to light-headedness or headaches.
Dry mouth and lips: This is a common sign that your body isn’t getting enough moisture.
Slower digestion: Dehydration can make constipation worse, something already possible with Wegovy use.
Long-Term Impact on Health and Progress
Reduced weight-loss results: When the body is dehydrated, metabolism slows down, which can stall progress and affect how the medication works.
Muscle loss instead of fat loss: Low water levels interfere with muscle recovery and may lead to temporary muscle shrinkage.
Strain on kidneys: Over time, dehydration can put pressure on your kidneys and impact how your body filters waste.
Greater discomfort from side effects: Symptoms like nausea or constipation may feel worse when hydration is poor.
Daily Hydration Strategies While on Wegovy
When you’re aiming to build a proper hydration habit on Wegovy or otherwise, following a clear strategy can make the task easier. Here’s how to keep your body balanced and your results steady:
1. Start Your Day with Water
Before breakfast or your Wegovy dose, drink a full glass of water. It helps wake up your system, supports digestion, and offsets the dryness many people feel in the morning.
2. Keep a Water Bottle Nearby
Whether you’re working, commuting, or at the gym, carry a reusable bottle wherever you go. This will keep water within reach, and you’re far more likely to sip throughout the day without forcing yourself to remember.
3. Set Reminders
Use your phone or a hydration app to remind you every hour or two. Many people on Wegovy forget to drink because their hunger cues are suppressed. Small nudges can make a big difference. You can also use a smartwatch if you have one for reminder purposes.
4. Flavour It Naturally
If plain water feels boring, add lemon, cucumber, berries, or mint leaves. This makes hydration more enjoyable without adding unnecessary sugar or calories.
5. Balance Caffeine and Alcohol
Tea, coffee, and alcohol can increase fluid loss. Try matching each caffeinated or alcoholic drink with a glass of water to stay balanced.
6. Listen to Your Body
Pay attention to early signs of dehydration. Some of these could be dry lips, fatigue, or darker urine. These small cues are easy to miss but can signal your body needs a refill.
7. Include Hydrating Foods
Many everyday foods contain high water content. Including them in your meals can help you meet your hydration goals without feeling like you’re forcing yourself to drink all day.
What Foods Help You Stay Hydrated on Wegovy?
We have curated a list of foods that not only support hydration but also aid digestion and provide energy throughout the day:
1. Fruits
Watermelon: About 90% water and packed with electrolytes like potassium.
Oranges: Naturally hydrating and rich in vitamin C to boost immunity.
Strawberries: High in antioxidants and water content. These are ideal as snacks or smoothie ingredients.
Grapefruit and melon: Help reduce bloating and keep you full longer.
2. Vegetables
Cucumber: Over 95% water, making it one of the best hydrating vegetables.
Lettuce and spinach: Light, refreshing, and perfect for salads or wraps.
Tomatoes: Contain both water and lycopene for heart health.
Courgette (zucchini): Adds hydration and fibre when grilled or spiralised.
3. Soups and Broths
Warm, light soups made with vegetables are an excellent way to add fluids while still feeling satisfied. Choose low-sodium options or make your own at home to avoid excess salt, which can dehydrate the body.
4. Yoghurts and Smoothies
Low-fat yoghurt and blended fruit smoothies contribute both hydration and nutrients. Opt for plain or Greek yoghurt with natural fruit instead of sugar-heavy alternatives.
5. Herbal Teas
Herbal teas such as chamomile, peppermint, or rooibos are caffeine-free and count toward your daily fluid intake. Enjoy them warm in the evening or chilled during the day.

FAQs
Does Wegovy cause dehydration?
Wegovy itself does not directly cause dehydration, but it can increase your risk of becoming dehydrated. Since it reduces appetite and slows digestion, many people eat and drink less than usual. Some may also experience nausea, vomiting, or diarrhoea, which can lead to fluid loss.
How many litres of water should I drink on Wegovy?
Drink 6 to 8 glasses daily. However, your exact needs depend on your body size, activity level, and climate. If you exercise or live in a warm environment, you may need slightly more. The goal is to keep urine light in colour and avoid long gaps without water.
Should I take electrolytes while on Wegovy?
You usually don’t need electrolytes every day, but they can help if you’re sweating heavily, experiencing vomiting, or feeling light-headed. Choose sugar-free or low-sugar electrolyte drinks to restore minerals like sodium and potassium. Always check with your healthcare provider.
Can dehydration affect weight loss on Wegovy?
Yes, dehydration can slow metabolism, reduce energy levels, and make you feel fatigued, which may affect how well you stay active or maintain healthy eating habits. It can also make early weight loss appear faster than it really is, since water loss is not fat loss.
What organs shut down first when dehydrated?
In severe dehydration, the kidneys are affected first since they rely on water to filter waste from the blood. Prolonged dehydration can then affect the heart and brain, leading to low blood pressure, confusion, and other serious complications
What not to eat when you are dehydrated?
Avoid salty snacks, fried foods, alcohol, and excess caffeine, as they pull water from your body and make dehydration worse. Processed or sugary foods can also strain digestion and increase fluid loss. Choose lighter meals with fruits, vegetables, and soups.
Can herbal teas or soups count toward daily water intake on Wegovy?
Herbal teas and light vegetable-based soups are excellent ways to stay hydrated, especially if you struggle to drink plain water. Choose caffeine-free teas and low-sodium soups so they contribute to your fluid balance rather than working against it.
What are the symptoms of being dehydrated?
Common signs of dehydration include a dry mouth or cracked lips, dizziness, fatigue, dark or strong-smelling urine, headaches, and constipation. If you experience persistent vomiting, confusion, or severe tiredness, consult your healthcare provider immediately.
