Why bleeding can occur in dengue

Dengue can make the lining of small blood vessels more fragile or leaky. It can also reduce platelets, the blood components that help seal damaged vessels, and disturb other clotting processes. Bleeding may show as nose or gum bleeding, easy bruising, blood in vomit or stool, or unusually heavy menstrual bleeding. Dengue Fever often presents with Fever, Headache, muscle aches, and Joint Pain, but bleeding is a warning sign rather than a measure of how mild the illness feels.

Bleeding can develop as fever changes, so feeling cooler does not by itself mean the danger has passed. A healthcare professional may monitor hydration, symptoms, examination findings, and blood tests over time.

Contact a clinician urgently if dengue is possible and bleeding appears. Rest, drink fluids in small frequent amounts if you can keep them down, and avoid aspirin or ibuprofen unless a clinician specifically tells you to use them because they can worsen bleeding risk. Use gentle pressure for a nosebleed and do not take medicines or supplements without checking first. Arrange a GP Consultation or emergency assessment according to the bleeding and your general condition.

Go to emergency care for vomiting blood, black stools, heavy vaginal bleeding, severe abdominal pain, repeated vomiting, faintness, unusual sleepiness, confusion, cold clammy skin, or difficulty breathing. Do not travel alone if you feel weak. Tell the team when the fever began, where you have travelled, and every medicine taken.

Ask how dengue will be confirmed or monitored, which fluids and medicines are suitable, whether you need repeat blood tests, and which changes mean immediate hospital care.
