According to the CDC, people with dengue should drink lots of fluids to stay hydrated. This is key to prevent dehydration from common symptoms like fever and vomiting. For this reason, knowing what liquids to drink is vital for home management.

Quick Summary

Hydration is crucial during dengue, as fluid loss from fever and vomiting can cause complications. Prioritize electrolyte-rich ORS, coconut water, plain water, fruit juices, and clear broths. Avoid sugary drinks, alcohol, and caffeine to help recovery.

Key Points

Prioritize Oral Rehydration Solution (ORS): Essential for replacing electrolytes lost through fever, vomiting, and diarrhea, which prevents severe dehydration.
Incorporate Coconut Water: This natural source of electrolytes, especially potassium, is gentle on the stomach and effectively restores hydration and energy.
Choose Fresh, Unsweetened Juices: Juices from fruits like orange, papaya, and pomegranate provide essential vitamins and antioxidants that aid recovery.
Drink Soothing Herbal Teas: Caffeine-free options like ginger or chamomile tea can provide warmth, hydration, and help settle the stomach.
Avoid Dehydrating Beverages: Steer clear of alcohol, caffeinated drinks, and high-sugar sodas, which can exacerbate dehydration and inflammation.
Maintain Consistent Fluid Intake: Aim for at least 3-4 liters of varied fluids daily for adults to ensure continuous hydration and recovery.
Consult a Doctor for Severe Symptoms: If oral hydration is insufficient due to persistent vomiting or other warning signs, seek immediate medical attention for possible IV fluid treatment.

The Importance of Hydration During a Dengue Infection

During a dengue fever infection, high fever, sweating, and potential vomiting can lead to significant fluid loss and dehydration. Dehydration can worsen symptoms and increase the risk of severe complications, such as dengue shock syndrome, which is a medical emergency. Maintaining proper hydration helps regulate body temperature, support blood circulation, and protect vital organs as the body fights the virus. The cornerstone of home care for dengue patients is ensuring an adequate intake of appropriate fluids.

Oral Rehydration Solution (ORS)

Oral Rehydration Solution (ORS) is one of the most effective and recommended fluids for dengue patients, particularly if they are experiencing vomiting or diarrhea. It is a carefully balanced mix of sugar, salt, and water designed to replenish lost electrolytes like sodium and potassium, which plain water alone cannot replace. ORS packets are widely available and can be mixed with clean drinking water following the manufacturer's instructions.

Coconut Water

Coconut water is a natural and excellent source of electrolytes, including potassium, which is often depleted during a dengue infection. It is gentle on the stomach, soothing, and provides a natural boost of hydration. Many people find it more palatable than ORS, making it a good supplement for fluid intake. Both fresh and packaged varieties are effective, but fresh is preferred to avoid added sugars.

Fresh Fruit Juices

While fresh fruit juices should be consumed without added sugar, they are a great way to rehydrate and replenish vitamins and minerals. Some of the best choices include:

Orange juice: Rich in Vitamin C, which boosts immunity.
Pomegranate juice: High in iron and antioxidants, which support blood health.
Papaya juice: Contains enzymes and vitamins that aid digestion and promote overall health.

Herbal Teas and Clear Broths

Warm liquids can be very comforting and soothing for dengue patients, who often experience body aches and fatigue. Herbal teas like ginger, chamomile, or peppermint are caffeine-free and can help soothe an upset stomach while contributing to hydration. Clear vegetable or chicken broths provide warmth, hydration, and some electrolytes and nutrients without burdening the digestive system.

Fluids to Avoid When You Have Dengue

Just as it is important to know what to drink, it is crucial to avoid certain liquids that can worsen symptoms or impede recovery.

Caffeinated drinks: Coffee, tea, and energy drinks act as diuretics, which can increase urine output and worsen dehydration.
Sugary drinks: Excess sugar can cause a temporary energy crash and inflammation. Avoid sodas and commercial fruit juices with added sugars.
Alcohol: Alcohol impairs the immune system and can contribute significantly to dehydration.
Aspirin and NSAIDs: While these are not fluids, it is critical to mention avoiding these medications. They can increase the risk of bleeding complications in dengue patients. Use acetaminophen (paracetamol) for fever and pain instead.

A Guide to Fluid and Electrolyte Options


Type of Liquid	Benefits for Dengue Patients	Cautions	Recommended Intake
Oral Rehydration Solution (ORS)	Replenishes lost electrolytes, especially with vomiting/diarrhea.	Must be mixed correctly with clean water; follow packet instructions carefully.	Sip small amounts regularly, as needed.
Coconut Water	Natural source of electrolytes, gentle on the stomach, and hydrating.	Fresh is best; check with a doctor if you have kidney or heart issues.	1-2 glasses per day, or as tolerated.
Fresh Fruit Juices	Provides Vitamin C, antioxidants, and minerals.	Avoid added sugar; dilute if very sweet.	Moderate intake, as part of overall fluid consumption.
Herbal Teas	Soothing, hydrating, and may help with nausea (e.g., ginger).	Ensure they are caffeine-free.	Sip throughout the day, especially if you have chills.
Clear Soups/Broths	Warm, nourishing, and replaces some lost fluids and minerals.	Avoid overly salty or greasy versions.	Can be consumed with meals or as snacks.
Plain Water	Essential for flushing toxins and regulating body temperature.	Plain water alone may cause electrolyte imbalance in severe cases.	Drink 8-10 glasses daily, combined with other fluids.

Conclusion

Proper hydration is the single most important aspect of at-home management for a dengue infection. While plain water is essential, supplementing with electrolyte-rich fluids like Oral Rehydration Solution (ORS) and coconut water can make a significant difference in recovery. These beverages help restore the body's mineral balance, preventing complications like dengue shock. Additionally, fresh, unsweetened fruit juices and clear broths provide valuable nutrients and comfort. Avoiding dehydrating liquids such as caffeine and alcohol is also critical. Always monitor symptoms and consult a healthcare professional, especially if experiencing persistent vomiting, severe abdominal pain, or other warning signs of severe dengue. This focused attention on hydration provides the body with the best chance for a smooth and effective recovery.

Frequently Asked Questions

An adult with dengue should aim for at least 3 to 4 liters of fluids per day through a combination of water, ORS, coconut water, and soups. This can be adjusted based on the patient's age and condition, but consistent intake is essential to prevent dehydration.

Yes, milk can be a good source of hydration and essential nutrients like protein, calcium, and vitamins during dengue. However, if you experience bloating or diarrhea, consider switching to lactose-free options or avoiding it temporarily and consult your doctor.

Plain water is necessary, but it is not sufficient on its own, especially with symptoms like vomiting and diarrhea. The body needs electrolytes to function properly, which are better supplied by Oral Rehydration Solution (ORS) or natural sources like coconut water.

Packaged fruit juices often contain added sugars and preservatives that can cause energy crashes and inflammation. It is best to opt for fresh, unsweetened fruit juices to maximize nutritional benefits without the negative effects of added sugars.

Herbal, caffeine-free teas like ginger, chamomile, or peppermint are excellent choices. They are soothing and can help with symptoms like nausea and body aches while contributing to your daily fluid intake.

You should seek immediate medical attention if you experience severe abdominal pain, persistent vomiting, bleeding from the nose or gums, cold and clammy skin, drowsiness, or decreased urination. These are all signs of severe dengue that may require intravenous (IV) fluid treatment.

A simple homemade ORS can be made by mixing one liter of clean water with six teaspoons of sugar and half a teaspoon of salt until dissolved. This solution helps restore fluids and electrolytes effectively.
