Nosebleeds, dizziness, headaches and extreme fatigue

Several symptoms together do not point to one diagnosis. Blood loss from repeated nosebleeds can contribute to tiredness or lightheadedness, while dehydration, heat exhaustion or low blood glucose can cause dizziness and weakness. Anaemia, including iron deficiency anaemia, may cause fatigue, headache and feeling faint, but a nosebleed does not establish that cause. Anxiety, an inner-ear problem such as benign paroxysmal positional vertigo, or a heart-rhythm problem can also produce dizziness for different reasons.

A clinician will ask when each symptom began, whether the room spins or you feel faint, how much bleeding occurred, and whether there are changes in vision, speech, movement or chest symptoms.

If the nose is bleeding, sit forward and pinch the soft part continuously. Rest in a cool place, take small sips of fluid if you are alert and able to swallow, and avoid driving while dizzy. Record the timing, triggers, medicines and any recent heat exposure or missed meals. Arrange prompt medical assessment rather than self-treating with iron or other supplements.

Call emergency services for sudden severe headache, fainting, confusion, new weakness or numbness, trouble speaking, vision loss, chest pain, severe breathlessness or uncontrolled bleeding. Get same-day advice for persistent dizziness, extreme fatigue, repeated nosebleeds, black stools, vomiting blood or symptoms after heat exposure. These warning signs require assessment based on severity, not on assuming one condition.

Ask whether you need blood pressure measurement, blood tests for anaemia, a review of medicines, heart-rhythm assessment or evaluation of balance and hydration. Describe the bleeding clearly and mention any pregnancy, chronic illness or recent infection.
