Diabetes Increases Severe Dengue Risk
People with Type 2 diabetes have a higher chance of getting very sick from dengue fever.
This is because high blood sugar can weaken their immune system and damage blood vessels.
Doctors say that diabetics should be extra careful and watch for symptoms like vomiting, severe pain, and bleeding.
They also recommend getting vaccinated and taking steps to prevent mosquito bites.
Managing diabetes well and staying hydrated can help reduce the risk of severe dengue.
People with Type 2 diabetes are at higher risk of severe dengue complications due to impaired immune function and damaged blood vessels.
High blood sugar can lead to an exaggerated inflammatory response, increasing the risk of dengue hemorrhagic fever and dengue shock syndrome.
Experts recommend integrating dengue vaccination into routine diabetes care in dengue-endemic regions.
Symptoms to watch for include persistent vomiting, severe abdominal pain, unusual drowsiness, bleeding, reduced urine output, dizziness, and sudden weakness.
Prevention measures include avoiding mosquito bites, using repellents, wearing long-sleeved clothing, eliminating stagnant water, staying hydrated, and managing diabetes well.
