Posted By Suborna Fermi Posted on Nov 09, 2022

Dengue is an awfully common mosquito-borne disease, which can be life-threatening without the proper dengue treatment. This fever affects millions of people around the world in a year. It causes severe discomfort and health complications to the patient.

Headache, fatigue, rashes, pain in the eyes, joints, muscles and bones are the most common symptoms of dengue fever. Besides, dengue also hugely impacts your platelet count in the blood. Here are the complete details regarding why platelet counts decrease in dengue fever.

What are platelets?

Platelets are the small fragments in our bloodstream, and they mainly produced through the bone marrow. They help in the formation of the blood clots which stops or slows down the bleeding. So, when the platelet count decreases your body fails in formation of blood clots, which leads to excess bleeding. Thrombocytopenia is a disease which indicates the rapid decreasing of the platelet count in the bloodstream. Low platelet count in dengue fever causes inability to form blood clots, and combat against the infection.

How does the platelet count decrease in dengue?

  • As the bone marrow gets suppressed in dengue infection, it fails to produce platelets
  • The dengue virus affected blood cells destroys platelets
  • The antibodies which forms at the time of the infection also damages the platelets

Generally, the platelet count of a normal human being is around 1.5 to 4 lakhs. With dengue this platelet count falls around 20 to 40 thousand. And an extremely low platelet count may cause internal bleeding. This is why the dengue patients need to be checked with platelet count tests regularly. You can find a handful of diagnostic centers, where the platelet count test price is not more than a few bucks.

However, platelet counts can be increased in dengue patients through regular transfusion and consuming some foods. Foods which are rich in Iron, Omega-3 fatty acids, Vitamin C, Vitamin K, and Vitamin B-12.
