Summer is a season many people look forward to all year long due to warmer weather, longer days, and more outdoor activities. However, with the rising temperatures also comes an often-overlooked health risk: dehydration. Dehydration is the lack of enough water in the body to function properly. It typically occurs when you lose more fluids than you take in. Your body often loses fluids by sweating, urinating or during times of illness due to vomiting or excessive diarrhea.

During the summer months, dehydration can happen quickly due to increased sweating, physical activity, and prolonged exposure to heat. You can usually treat mild dehydration by drinking more fluids. But dehydration is not always easily recognized. When you are not properly hydrated, your body’s natural response is thirst. You should respond to thirst right away by drinking fluids — preferably water. While mild dehydration may seem harmless, it can lead to serious health problems if left untreated.

Why Dehydration Is Dangerous

Water plays a vital role in nearly every function of the body. It helps regulate temperature, transport nutrients, aid in digestive functions, lubricate joints, and supports organ function. When your body does not have enough fluids, these processes begin to be negatively affected.

Early signs of dehydration include:

    • Thirst
    • Dry mouth
    • Fatigue
    • Headaches
    • Dizziness
    • Dark-colored urine

If dehydration worsens, symptoms can become more severe, including rapid heartbeat, confusion, fainting, and heat-related illnesses such as heat exhaustion or heat stroke. Young children, older adults, and people with chronic health conditions are especially vulnerable.

Use of certain medications, such as diuretics, for hypertension and heart failure, and GLP-1 medications, for weight management and diabetes, can pose an increased risk of dehydration. People taking these medications may need to pay extra attention to their hydration status, especially during the summer months.

Understanding GLP-1 Medications and Hydration

GLP-1 receptor agonists, such as Ozempic, Wegovy, and Mounjaro, have become increasingly popular for supporting weight loss and managing type 2 diabetes. These medications work by helping regulate blood sugar levels, slowing stomach emptying, and increasing feelings of fullness.

While highly effective and safe for many people, GLP-1 medications can sometimes cause side effects that may increase the risk of dehydration, including:

    • Nausea
    • Vomiting
    • Diarrhea
    • Reduced appetite
    • Lower overall fluid intake

Because these medications can decrease hunger and thirst cues in some individuals, people may unintentionally consume less water throughout the day. During periods of hot weather, this combination can make dehydration more likely.

Understanding Diuretic Therapies and Hydration

Diuretics are used commonly to help in the management of hypertension and congestive heart failure. These medications work by removing excess fluids from the body. The removal of excess fluids is important for the management of congestive heart failure, as this prevents the heart from working too hard when moving blood throughout the body.

However, the body can be at risk of losing too much fluid due to increased sweating, increased physical activity and prolonged exposure to heat during summer months. It is important to hydrate effectively when on diuretics to support kidney function and prevent dehydration.

Common Causes of Dehydration

Many people underestimate how much fluid they lose, especially during hot weather. Some common causes include:

    • Spending time outdoors in high temperatures
    • Exercising without replacing lost fluids
    • Drinking alcohol, which can increase fluid loss
    • Forgetting to drink water throughout the day
    • Illnesses that cause vomiting, diarrhea, or fever
    • Side effects from medications, including GLP-1 therapies

Even on cloudy days, high humidity and warm temperatures can contribute to dehydration.

How to Prevent Dehydration

The good news is that dehydration is often preventable with a few simple habits:

  • Drink Water Regularly - Do not wait until you feel thirsty. Thirst is often a sign that dehydration has already begun. Carry a reusable water bottle and sip throughout the day, especially when outdoors. Exactly how much water you need depends on your weight, age, level of activity, the climate of your environment as well as other factors. It is generally recommended that adults drink 2 to 3 liters of water a day if not contraindicated. If you are unsure, talk with your health care provider about your ideal level of fluid intake.

     

  • Eat Hydrating Foods - Many fruits and vegetables have high water content and can help keep you hydrated. Some examples of hydrating foods include watermelon, cucumbers, strawberries, oranges, and lettuce.

  • Limit Alcoholic Drinks - Alcohol is further dehydrating because it acts as a diuretic, increasing urine production and causing the body to lose fluids and electrolytes. Water should remain your primary source of hydration. Consider adding an electrolyte replacement when spending extra time outdoors or after exercising.

  • Dress for the Weather - Wear lightweight, loose-fitting clothing and light colors to help your body stay cool. A wide-brimmed hat and sunscreen can also reduce heat stress.

  • Take Breaks from the Heat - If you are working or exercising outdoors, schedule breaks in shaded or air-conditioned areas. Avoid strenuous activity during the hottest parts of the day, typically between 10 a.m. and 2 p.m.

  • Know your medication risks - Ask your doctor if any of your medications make you more likely to become dehydrated and work together on an action plan to avoid the risk.

Dehydration can develop faster than many people realize, especially during the hottest months of the year. By drinking water consistently, eating hydrating foods, and taking precautions in the heat, you can reduce your risk and enjoy a safe, healthy summer. A little prevention goes a long way. Staying hydrated is not just a “hot” weather topic—it is an essential part of protecting your health all season long.

Clinical Research

At Chase Medical Research we have multiple ongoing trials for newly developed drugs. Some of our most popular therapeutic areas include weight loss, and management of chronic conditions such as uncontrolled blood pressure, diabetes, and high cholesterol. When you are participating in a clinical trial, blood work is regularly obtained to assess safety risks such as dehydration and/or kidney injury. Participating in clinical trials helps to increase awareness of these risks and in some cases can identify changes in conditions sooner, sometimes before symptoms develop. Contact us at (203) 419-4404 if you are interested in learning more about our currently enrolling trials.
