5 main sequelae and complicationsções of dengue

Complications of dengue occur when the disease is not identified and treated in the early stages, or when the necessary care during the disease is not followed, such as rest and constant hydration. Some of the complications that can be caused by dengue are severe dehydration, liver, heart, neurological and/or respiratory problems, in addition to dengue hemorrhagic fever, which is a severe reaction to the dengue virus that leads to bleeding.

Dengue is a disease caused by the virus, known as dengue virus, which is transmitted to people through the bite of the Aedes aegypti mosquito, leading to symptoms such as pain all over the body, the appearance of red spots on the skin, extreme tiredness, nausea and high fever.


Some of the complications that can happen as a result of dengue are:

1. Hemorrhagic Dengue

Dengue hemorrhagic fever is a type of dengue that usually appears, most often, when you are infected more than once by the virus, leading to changes in blood clotting. This disease causes bleeding especially in the eyes, gums, ears and nose, as well as the appearance of blood in the stool, red spots on the skin, vomiting and a weak and rapid pulse.

This type of dengue, if not treated quickly, can lead to death and its treatment must be done in the hospital so that bleeding and hydration of the body can be controlled. Learn how to identify dengue hemorrhagic fever.

2. Severe dehydration

Dehydration is one of the most common consequences of dengue and can be perceived through some signs and symptoms such as extreme tiredness, thirst, weakness, headache, dry mouth and lips, chapped lips and dry skin, sunken eyes and funds and increased heart rate.

Dehydration can be treated and prevented by ingesting homemade serum, fruit juices, teas and water while you are sick, but in the most serious cases it may be necessary to go to the hospital for dehydration treatment to be done. with saline administered directly into the vein.

3. Liver Problems

Dengue, when not treated correctly, can cause hepatitis and/or acute liver failure, which are diseases that affect the liver, leading to changes in the functioning of the organ. In the most severe cases, these diseases can lead to irreversible liver damage, which may require a transplant.

When there are liver problems, symptoms of vomiting, nausea, severe pain in the belly and abdomen region, pale stools, dark urine or yellow skin and eyes are usually present.

4. Neurological Problems

Some of the complications that arise when the dengue virus reaches the brain are encephalopathy, encephalitis and meningitis. In addition, dengue can also cause Myelitis, an inflammation of the spinal cord, and Guillain-Barré Syndrome, an inflammation that affects the nerves and results in muscle weakness and paralysis, which can be fatal. Understand more about Guillain-Barré Syndrome.

These complications can happen because the dengue virus can pass directly into the bloodstream, reaching the brain and the Central Nervous System, causing inflammation. In addition, the virus can also cause an exaggerated reaction of the immune system, causing it to produce antibodies against the virus that end up attacking the organism itself.

When the dengue virus affects the Central Nervous System, there are specific symptoms such as drowsiness, dizziness, irritability, depression, seizures, amnesia, psychosis, lack of motor coordination, loss of strength on one side of the body, in the arms or legs, delirium or paralysis.

5. Heart and Respiratory Problems

Dengue can also lead to pleural effusion, when it reaches the lungs, or myocarditis, which is inflammation of the heart muscle.

When breathing or heart problems are present, some of the symptoms that may be experienced include shortness of breath, difficulty breathing, cold, bluish hands and feet, chest pain, dry cough, muscle pain, or dizziness.

All these problems must be treated in the hospital, as they are more serious complications that require adequate treatment and constant clinical follow-up. In addition, it is very important to always be aware of the symptoms presented, because when not properly treated, dengue can progress to death.
