Black Stool During Dengue Treatment

During dengue care, black sticky stool can reflect digested blood from the upper digestive tract. It may also be caused by iron or bismuth, so the colour alone cannot identify the cause. The treating team needs to know about it because dengue can increase concern about bleeding. Note whether the stool is tarry rather than simply dark brown, and report dizziness, abdominal pain, vomiting, bruising, or unusual tiredness. Fever, headache, chills, joint pain, and muscle aches may continue during dengue, but black stool is a separate warning sign.

Call the clinician or treatment centre managing the dengue today and describe the stool precisely. Provide the names and times of all prescribed and non-prescribed medicines, including supplements. Do not stop a prescribed medicine or add aspirin, ibuprofen, naproxen, or herbal products without instructions. Keep drinking only as advised by the clinical team; seek help if vomiting prevents fluids. Save a photograph if it can be taken without delaying care, because appearance and timing can assist assessment.

Use emergency services for repeated tar-like stools, vomiting blood, fainting, confusion, severe pain, cold clammy skin, breathing difficulty, or a sudden decline. Bleeding from the gums or nose, spreading bruises, severe weakness, or reduced urination also calls for urgent attention. Arrange transport rather than driving when light-headed, and take the treatment record with you.

Ask whether any current medicine could darken stool, whether testing for bleeding is needed, which pain medicine is safe, and what symptoms should trigger hospital review. Mention the first black bowel movement, its texture, any repeat episodes, and every accompanying symptom.
