- GLP-1 medications may increase heat-related risks by suppressing thirst and reducing fluid intake.
- Thirst reduction may lead to severe dehydration and even kidney damage.
- GLP-1 drugs may also lower blood pressure in some people, potentially leading to other heat-related issues in people with low blood pressure.
- People using GLP-1s also need to properly store their medications, as heat can damage them.
Heat waves during the summer months are increasingly common. What does this mean for people using GLP-1 drugs like Ozempic, Wegovy, or Mounjaro?
GLP-1 medications may increase the risk of dehydration, particularly in hotter weather.
Proper storage of these drugs is also important, as heat can damage the medication and render it ineffective.
Clare Thompson, general practitioner and lead of the weight management services at Cadogan Clinic in the United Kingdom, advised extra precautions during hot weather for those taking GLP-1 drugs.
Healthline spoke with Thompson about how taking GLP-1s may lead to dehydration and other heat-related illnesses, and how to properly store the medication during hot weather.
This interview has been lightly edited for length and clarity.
Thompson: GLP-1 medications suppress your natural thirst cues, which means you naturally drink less fluid.
They can also delay stomach emptying and cause nausea, which may result in drinking less fluid
GLP-1 medications seem to lower blood pressure in some patients, which can also make patients susceptible to dizzy spells and fainting.
This is further compounded by the heat, which can cause you to sweat more and lose further fluids.
This slight lowering of blood pressure can sometimes be beneficial in people with hypertension.
However, in patients with pre-existing normal to low blood pressure, special consideration must be taken to ensure their pressure doesn’t drop to dangerously low levels.
Thompson:There are simple steps patients can take to mitigate dehydration while taking GLP-1 medications during a heatwave.
Drink electrolytes instead of plain water to replenish the sugar and salts needed to maintain hydration and bodily functions.
Aim for 1.5–2 L of fluids per day and set a reminder on their phone to prompt them to drink.
The heat itself also suppresses appetite, so having smaller, protein-rich foods can help stabilize blood sugar and prevent the effects of low blood glucose and feeling faint.
Cutting back on alcohol and caffeinated drinks, which are diuretics and cause further fluid loss, can also help prevent dehydration.
Thompson: Extreme heat can also damage the medication and alter the properties of the proteins.
To protect the medication, store it away from direct sunlight. Ideally, it should be in the fridge at 2–5°C (35.6F–41F) before opening, or at room temperature once used.
GLP-1 medications should not go above 30°C (86F).
Use an insulating pouch or cool bag when traveling with the pen to prevent extreme temperature changes that could damage the medication.
