Monsoon is fantastic only if you have the luxury of working from home. Otherwise, water logging, traffic, cab surcharges, mosquito, fever makes life miserable. Dengue has become like an epidemic now in certain parts of the country. One in almost every alternative family is suffering from dengue or some sort of viral fever. I am also not an exception. This monsoon didn’t only give me a few wonderful evening with family over a cup of chai and bhaji (tea and fries) but also few rounds to hospital for a close one dengue fever treatment. Ah! that’s life.

Dengue is a viral infection, transmitted by mosquito. As per WHO, the incidence of dengue in the world is dramatically increased in recent decades. If you or any of your close one has ever suffered from dengue then you know it’s NOT only the fever but multiple other symptoms completely break the person from inside out. Extreme weakness, apathy, joint pain, muscle cramps, sometimes itching, etc makes life hell. There is no specific treatment for dengue/ severe dengue, but medical care is needed. No vaccine is available for preventing this disease. There is a high risk of death from Dengue infection, particularly if it is not detected at an early stage. early detection and access to proper medical care lowers fatality rates below 1%. Early detection and prompt initiation of appropriate treatment are vital for avoiding serious complications. Diet plays a vital role in dengue fever treatment. A proper diet helps to recover fast and minimize the intensity of various symptoms. (1,2)

Dengue fever treatment: Who is at risk?

It’s simple. About half of the world’s population is now at risk. World Health Organisation (WHO) estimated that around 390 million people in the world get infected by dengue virus each year. Anybody -infants, young children and/or adult men and women – are at risk in countries from the tropical and sub-tropical region. As per WHO, currently, dengue is epidemic in 128 countries from Africa, America, Eastern Mediterranean, South-East Asia, and Western Pacific. People live in urban and semi-urban areas are at higher risk. (1)

Dengue fever treatment: Who is the culprit?

Dengue is a mosquito-borne disease. Dengue virus is transmitted by female mosquitoes of Aedes aegypti species. The infected female mosquitoes incubate for 4–10 days and then it is capable to transmit the virus for the rest of its life. Individuals get infected by Dengue virus by the bite of an infected mosquito. Patients who are already sick with the dengue fever can transmit the infection (for 4–5 days; maximum 12) via Aedes mosquitoes after the appearance of their first symptoms. The mosquito bites during the day time. (1)

Bottom Line

Dengue is a mosquito-born, serious viral infection. The mosquito bites during the day time. There is no specific vaccine or treatment against Dengue fever. Early detection and appropriate medical care are necessary to avoid serious complications. It occurs both in children and adults. People living in the tropical and sub-tropical countries in the urban and semi-urban areas are at highest risk of getting infected with Dengue virus. Approximately 3.9 billion people, in 128 countries, are at risk of dengue infection.

Dengue fever treatment: Signs and symptoms

Dengue fever is a severe, flu-like illness that affects anyone irrespective to their age and sex. The symptoms of Dengue fever are overlapping too many other viral fevers, for that reason, it is frequently misdiagnosed by the doctors. In today’s scenario, where dengue infection is so wide-spread, all of us, including the patients, their relatives, and obvious doctors should be well-concerned regarding the symptoms of the disease.

Dengue fever treatment 2

World Health Organization (WHO), suggested that Dengue should be suspected when a high fever (40°C/104°F) is accompanied by any 2 of the following symptoms-

  • severe headache
  • pain behind the eyes
  • muscle and joint pains
  • nausea and vomiting
  • swollen glands or
  • rash

Anyone suffering from high fever along with other symptoms must go to the doctor for initiating the appropriate medical care which is essential for the early recovery from Dengue fever and avoiding the complications. When an infected mosquito bites a healthy person, the first symptom usually occurs after 4-10 days and the symptoms usually persist for 2-7 days. The severity of Dengue viral infection usually is moderate to severe.

Severe dengue causes many potentially deadly complications like-

  • Plasma leaking
  • Fluid accumulation
  • Respiratory distress
  • Severe bleeding, or
  • Organ impairment.

Warning signs usually occur 3–7 days after the appearance of first symptoms in association with a decrease in body temperature (below 38°C/100°F). The warning signs, requiring urgent medical attention, are-

  • severe abdominal pain
  • persistent vomiting
  • rapid breathing
  • bleeding gums,
  • fatigue,
  • restlessness and
  • blood in vomit.

The next 24–48 hours after the appearance of the warning signs, is the critical period requiring proper medical care to avoid complications and risk of death. (1)

Bottom Line

WHO suggested that Dengue should be suspected when a high fever (40°C/104°F) is accompanied by any 2 of the symptoms like severe headache, pain behind the eyes, muscle and joint pains, nausea, and vomiting, swollen glands or rashes. The severity of Dengue viral infection usually is moderate to severe, which persist for 2-7 days.

Severe abdominal pain, persistent vomiting, rapid breathing, bleeding gums, fatigue, restlessness and blood in vomit, etc are the warning signs. Any Dengue patient experiencing any of the above symptoms should immediately rush in the nearby hospital, requiring immediate medical attention.

Dengue fever treatment: The Diet

Dengue is a self-limiting infectious viral disease. Though appropriate medical care is essential for Dengue patients there is no specific treatment for the Dengue fever. Dengue causes several moderate to severe symptoms.

Why following a proper diet is essential for dengue fever treatment?

One must take diet seriously while suffering from dengue for the following reasons-

  • Reducing the severity of symptoms like nausea, vomiting, etc.
  • Improving their food tolerance
  • Preventing severe complications like gastrointestinal bleeding, dehydration, etc.
  • Improving the platelet count and detoxifying the body.
  • Ensuring early recovery of the patient.

What to eat while suffering from dengue?

It depends on the stage of dengue fever.

Stage 1: Liquid Diet for the initial stage of Dengue infection when a high fever is present

Stage 2: Soft Diet for the Dengue Patients when the fever subsides and he/she gradually recovers

Stage 3: Normal Diet during recovery

Dengue fever treatment Stage 1: Liquid Diet guideline

You can’t eat. Actually, you don’t feel like eating anything at this phase. So don’t eat. Just keep drinking various liquids. Dengue patients usually feel nausea, vomiting, and extreme weakness, in this condition liquid diet is recommended for them, which is comparatively better tolerated than the solid diet. Small and frequent intake of liquid foods is suggested. Liquid diet supplies a lot of water which help to replace the fluid loss in high fever and to bring down body temperature. Solid foods should be avoided until the fever is gone. Drinking of plenty of water is essential for replacing the fluid loss in a high fever. Solid foods should not be taken until the

5 reasons to drink coconut water

Oral rehydration solution (ORS): ORS hydrate the body and prevent dehydration. It supplies potassium to the body. Don’t use half packet in a glass of water or something else. Dissolve one 20g (approx) sachet in 1 liter of water and keep sipping throughout the day. Finish it within 24 hrs or discard the liquid. Remember the concentration of the liquid is important.

Orange juice: It provides vitamin-C and is beneficial for those suffering from Dengue fever. Drink this if it’s in the season.

Black grape juices: It is helpful for blood formation. It is also rich in antioxidants. Don’t forget to wash the grapes thoroughly. Keep the grapes in saltwater for 40-60 minutes and then wash in running water.

Guava juice: This might sound difficult but very effective. In most cases, the blood platelet count is reduced in Dengue fever. Guava juice is effective to increase the platelet count.

Pomegranate juice: It also helps in blood formation. Check the beetroot-pomegranate recipe HERE.

Spinach soup: Spinach is rich in vitamin K, potassium, iron, and phytonutrients like carotene B and Lutein zeaxanthin, etc.

Beetroot soup: Beetroot contains a very high amount of water, vitamin (B9, Vitamin C), minerals (manganese, potassium, iron) these were very helpful in increasing the RBC count.

Tomato soup: Tomato is also rich in vitamin C and potassium.

What not to drink?

I know making fruit juices or vegetable soup is a task. Do not try to make your life easy with packaged fruit juices or instant soup mix or soft drinks. No matter how healthy they claim, they are nothing but a mixture of various form of sugar, chemicals, and preservatives.

Yes, often they claim that they are added with vitamins and minerals but the study suggests that mostly they are not being absorbed in our gut. So it’s pointless. Make fresh juice, soup at home. it’s the best choice any time any day.

Why liquid diet is suggested in the initial phase of Dengue Fever?

Liquid Diet is recommended due to the following reasons-(4)

  • The liquid diet is better tolerated than solid foods.
  • Liquid foods are rich in vitamins, minerals, etc. which help in the rapid recovery of the patients.
  • They are useful to reduce the severity of the symptoms like nausea, vomiting, and fever.

Papaya leaves-

Papaya leaf has a great potential to fight against dengue. The juice of raw papaya leaves is an effective herbal therapy for curing dengue fever. Fresh papaya leaves should be collected, washed, crushed and the juice is to be squeezed and filtered using a clean cotton cloth. One leaf provides approximately one tablespoon of juice. The juice is quite bitter, so it should be sweetened with honey or sugar or mixed with fruit juices. Dengue patients should consume 2 tablespoons of papaya leaf juice, 3 times daily, at 8 hours interval. The leaf should not be boiled or cooked since heat reduces the beneficial effects of papaya juice. (5, 6,7)

Guava leaves –

Intake of guava leaf juice is beneficial for Dengue patients. Fresh guava leaves should be collected and cleaned with water. Then the 1 cup of leaves is to be blended with 1 cup of water in a juicer into a smooth paste and should be strained using a strainer. The juice can be stored for 3 days in the refrigerator. (8)

Neem leaves –

It’s available almost everywhere. Neem leaves are very effective for increasing the production of white blood cells and platelets. It helps to boost immunity. (9)

Bottom Line

Proper dietary management is essential for early recovery and avoiding the complications of Dengue fever. Initially, a liquid diet is suggested which is better tolerated by the patients. It helps to reduce symptoms like nausea, vomiting, fever, and dehydration. A liquid diet is a very good source of several vitamins, minerals, and antioxidants which ensure early recovery of the patient.

When the liquid diet is well retained and well tolerated by the patient, softly cooked foods are introduced at frequent intervals along with the liquid diet. Soft diet makes the bridge between the liquid diet and normal diet. It is easy to consume, easy to digest and improve appetite gradually. As the patient recovers, gradually soft diet should be gradually changed into a more normal daily diet. Coriander leaves, neem leaves, guava leaves, and papaya leaves are found to be extremely effective for boosting the WBC and platelet count in the blood.

Dengue fever treatment – Stage 3: Normal Diet Guideline

When the patient recovers and the soft diet is well retained and well-tolerated, gradually soft diet is to be changed into a normal daily diet. During the recovery period, the patient should consume a high calorie, high protein, low-fat, non-spicy diet rich in vitamins, minerals, and antioxidants. Drinking of plenty of water is essential for them for rapid recovery.

1. Calories

The diet should supply adequate calories. This is required to regain the strength of the body which was lost during Dengue infection. Energy-rich foods like rice, potato, fruit juice, milk should be included in the diet.

2. Proteins

It should be a high protein diet because protein is essential for the repairing of the body tissues. Easily digestible, high protein foods like milk, chicken stew, non-spicy fish curry, softly cooked paneer curry, boiled egg, dal, etc. should be included. Are you a vegetarian?Thinking of what to eat for getting enough protein? Consider reading this –

3. Fats

Dengue reduces digestive capacity. It is difficult for a dengue patient to digest fat properly. So, the diet should be of low-fat content. Avoid taking fried foods for a time being. A teaspoon of ghee can be taken in lunch or dinner if tolerated. Avoid all sort of outside foods- fried or nonfried. Always choose right kind of oil and good quality ghee.

4. Carbohydrates

The diet should be rich in carbohydrates as they are the principal source of energy. Easily digestible carbohydrates are preferred than high fiber foods. Rice, oats are preferred than wheat and millet.

5. Vitamins and minerals

Adequate intake of vitamins and minerals are essential. So, plenty of freshly prepared vegetable soups and fresh fruit juices should be included in the diet. These fruits not only supply vitamins and minerals, but they are also rich sources of antioxidants and many phytochemicals which play beneficial roles in the rapid recovery of the Dengue patients. Drinking of coconut water and lemon water are also good for these patients.

6. Fluids and water

Drinking of plenty of fluids is necessary for the patients to hydrate the body and removing of the toxins from the body. The person recovered from Dengue fever should drink water as much as he/she can consume. Fluid like foods like juices, soups, sharbat, coconut water, etc. also provides additional water. Artificial packaged fruit juices in the name of “real” or “natural” or instant soup mixes are to avoided at all cost.

7. Spices

Dengue fever is associated with digestive complications like nausea, vomiting, etc. and there is a risk of gastrointestinal bleeding. So, a non-spicy diet is recommended for these patients. Minimum spices should be used in cooking. Chilies should be avoided.

Special Considerations

  • The diet should be easily digestible.
  • Any foods which may produce flatulence and indigestion should be avoided. It is better to avoid cauliflower, cabbage, radish, etc. as they are difficult to digest.
  • A moderate amount of pulses should be taken but not in an excessive amount as they may cause flatulence. Before cooking, pulses should be soaked in excess water for at least 2 hours.
  • All types of cold drinks and alcoholic beverages should be avoided. Maximum 2-3 cups of coffee and tea can be taken but they should not be too hot.
  • Milk should be taken in plenty of amounts if it is well tolerated. But if the patient has difficulty to digest milk, it should be avoided.
  • Milk products like Dahi, yogurt, chaas, buttermilk, etc. should be given in plenty of amounts because these foods are easily digestible, nutritious dairy products. Compared to milk, these fermented milk products are better tolerated by Dengue patients. These foods are rich in probiotics which helps in early recovery of the patients and help to increase the platelet counts.

Bottom Line

A high calorie, high protein, low-fat diet rich in vitamins, minerals, and antioxidants is appropriate for the patients. Drinking of plenty of fluid is mandatory for rapid recovery. The non-spicy diet should be easily digestible. The diet should contain an adequate amount of probiotic-rich foods like curd, buttermilk, etc. Too hot and too cold foods should not be given. Alcoholic beverages and cold drinks should be avoided. Freshly prepared fruit juices and vegetable soups are recommended. Any food which is not tolerated by the patient should be removed from his/ her diet.

Go for the blood tests and immediately rush in the nearby hospital for immediate medical attention. After the appearance of the first warning symptom, the next 24–48 hours are the critical period requiring proper medical care to avoid complications and risk of death. No, don’t panic. Just keep taking prompt action as required.

Diet pay a major role in dengue fever treatment. Proper dietary management is essential for early recovery and avoiding the complications of Dengue fever. Initially, a liquid diet is suggested, followed by a soft diet and normal diet. Judicious dietary management ensures the early recovery of the patient and reduces the complications of the symptoms. Both the soft diet and normal diet can provide all nutrients to the patient. A high calorie, high protein, low-fat diet rich in vitamins, minerals, and antioxidants is appropriate for the patients.
