What to do if you have diarrhea with dengue fever

Diarrhea refers to loose or watery stools. In general, diarrhea associated with dengue fever may be caused by immune responses, dehydration, drug side effects, intestinal flora imbalance, or viral infection. It is recommended to seek medical attention promptly and receive symptomatic treatment under a doctor's guidance. Specific causes are analyzed as follows:

1. Immune Response

After dengue virus infection, the body's immune system activates to eliminate the virus. During this process, immune cells and inflammatory mediators may attack the intestinal mucosa, causing intestinal damage and resulting in diarrhea. Patients may follow medical advice to use medications such as amoxicillin capsules, levofloxacin hydrochloride capsules, or azithromycin capsules to help alleviate symptoms.

2. Dehydration

The dengue virus can damage cells in the body, increasing plasma osmotic pressure and leading to dehydration, which in turn causes insufficient blood volume. This affects gastrointestinal blood supply, resulting in gastrointestinal dysfunction and diarrhea. Therefore, diarrhea in dengue fever may result from dehydration. Replenishing fluids and electrolytes helps maintain the body’s fluid and electrolyte balance and can relieve symptoms.

3. Drug Side Effects

If patients with dengue fever are taking medications, certain drugs—such as antivirals, antibiotics, or antipyretics—may irritate or affect the gastrointestinal tract, causing congestion, edema, and increased secretions in the gastrointestinal mucosa, thereby leading to diarrhea. Symptoms may be alleviated by switching medications or adjusting dosages.

4. Intestinal Flora Imbalance

Invasion by the dengue virus may disrupt gastrointestinal function, leading to an imbalance in gut microbiota. An imbalanced gut flora may reduce the number of beneficial bacteria and weaken their protective effect on the intestinal mucosa, making it easier for pathogens to invade and cause inflammation and diarrhea. Thus, diarrhea in dengue fever may be due to intestinal flora imbalance. Under medical supervision, medications such as mosapride citrate tablets, domperidone tablets, or omeprazole enteric-coated capsules may be used for treatment.

5. Viral Infection

Dengue virus is transmitted by mosquitoes. After infection, it may trigger a strong immune response that affects gastrointestinal function, causing gastrointestinal inflammation and functional disturbances, thus leading to diarrhea. Therefore, diarrhea in dengue fever may be caused by viral infection. As directed by a physician, medications such as doxycycline hydrochloride tablets, ibuprofen sustained-release capsules, or acetaminophen tablets may be used to relieve symptoms.

In daily life, it is recommended to consume foods rich in protein, vitamins, minerals, and other nutrients, such as eggs, lean meat, tomatoes, apples, etc., to provide necessary energy and support overall health.
