7 dangerous complications of dengue fever
(Baonghean.vn) - Dengue fever is a dangerous disease. When infected, the patient often does not have obvious symptoms, so it is difficult to detect. If dengue fever is not treated promptly, it will cause dangerous complications later. So how scary are the consequences of dengue fever? Find out in the article below.
1. Hemorrhagic shock
Because hemorrhage causes increased capillary permeability, plasma leakage and blood concentration, the manifestation of shock is that blood will be pushed out. In this case, there will be a lot of bleeding such as nosebleeds, bleeding gums, through open wounds. The loss of a lot of blood causes the body to be exhausted and have a high fever for a long time, sweating, and vomiting a lot.
2. Eye complications
There are two types of eye complications, the first is sudden blindness due to retinal hemorrhage, which damages the blood vessels of the retina and causes vision to decrease. The second is hemorrhage in the vitreous humor. The vitreous humor is a vitreous fluid in the eyeball that helps us see things. When a patient has hemorrhages, this fluid covers and dissolves, making the patient almost blind.
3. Heart and kidney failure
Dengue fever can lead to heart failure due to continuous bleeding. The heart is not strong enough to pump blood, combined with hemorrhagic plasma causing pericardium to overflow and stagnate. The kidneys are also affected due to having to work at full capacity to excrete plasma through urine... This can lead to acute kidney failure.
4. Coma
When there is internal bleeding, plasma can accumulate in the meninges through the blood vessel walls, causing cerebral edema and neurological syndromes leading to coma. This is the most severe complication of the disease. In addition, there are some cases of secondary coma after shock, after massive internal bleeding, after acute liver and kidney failure, ... in this case, secondary acute encephalopathy syndrome, is considered a complication.
5. Pleural effusion
Plasma leakage in the body can cause respiratory tract infection, pleural effusion or pneumonia, acute pulmonary edema. If not treated promptly, it can be life-threatening.
6. Low blood pressure, severe headache
In severe cases, dengue patients will have difficulty standing and walking due to a sudden drop in blood pressure. The patient will then have a severe headache. This is the most serious complication of dengue fever because it often causes brain hemorrhage and death.
7. Premature birth, miscarriage
Pregnant women with dengue fever will face many dangers. In the first days of fever, pregnant women may have a high fever, leading to a faster fetal heart rate, affecting the fetus. From the 4th to the 7th day of dengue fever, pregnant women are at risk of thrombocytopenia, leading to dengue hemorrhagic fever. Doctors say that pregnant women with dengue fever in the first months can lead to miscarriage.
