What is a red flag symptom?

A red flag symptom is something abnormal about your body or mind, that may indicate something is significantly wrong. ‘Red flag’ means potentially serious (and potentially treatable). See you doctor soon (even today) if you think you have one

So. What are the 10 red flag symptoms? There are two types of red flag symptoms, and we will describe 10 in each type.

10 common acute red flag symptoms

Definition. Acute symptoms = a rapid onset of symptoms that have started recently (last 24 hours), and you feel may be serious. Below are some examples of acute red flag symptoms, and what they could indicate:

1. Severe chest pain – heart attack, aortic dissection, pulmonary embolus (clot in lungs), collapsed lung
2. Severe headache – bleed in brain (e.g. subarachnoid haemorrhage), meningitis (a brain infection), head injury
3. Shortness of breath – heart failure, or COPD/asthma
4. Weakness on one side (or speech disturbance) – stroke
5. High fever or feeling very cold (especially with rash) – infection (sepsis, including meningitis).

Other acute red flag symptoms

1. ‘3Cs’ – reduced Consciousness, Collapse or Confusion (new) – many causes including infection (sepsis), side effects of medication, recreational drugs/alcohol (excess or withdrawal), low blood pressure
2. Uncontrolled heavy bleeding (e.g. vomiting, in poo, in wee, or out of vagina) – many causes
3. Loss of eyesight or severe eye pain – many causes including bleed, blod clot, glaucoma, uveitis, giant cell arteritis
4. Severe abdominal pain – appendicitis, ectopic pregnancy, bowel obstruction, AAA, renal colic
5. Possible fracture – any part of arm and leg, pelvis.

What should I do if I have an of these acute red flag symptoms?

If you have any of these symptoms, do not go to your GP. Go to your nearest A&E. If you are too unwell to do that, dial 999 and request an ambulance. You need to get there ideally in less than 2 hours. We are here to help you.

10 common chronic red flag symptoms

Definition. Chronic symptoms = a slower onset of symptoms that occurs over a few weeks, and you feel may be serious. Below are some examples of chronic red flag symptoms, and what they could indicate:

1. Blood in urine (wee) – bladder or kidney cancer
2. Blood in faeces (poo) – bowel cancer
3. Vaginal bleeding in a woman whose periods have stopped – uterine (womb) or cervical cancer
4. New severe back pain or inability to walk, loss of control of bowels or bladder – spinal cord compression
   Note. This is really a subacute problem, as it may need surgery soon (today/tomorrow)
5. Blood in sputum (spit) – lung cancer.

Other chronic red flag symptoms

1. Swollen ankles or shortness of breath – heart or kidney failure
2. Unexplained weight loss, abdominal or bone pain – cancer
3. A lump in your breast, or change in the nipple – breast cancer
4. Unexplained or changing lump(s) or mole anywhere in body – skin cancer
5. Unexplained deteriorating health or function – with failure to respond to treatment.

What should I do if I have an of these chronic red flag symptoms?

If you have any of these, please see your NHS GP soon (ideally the next two-to-three days) and ask to be seen face-to-face and examined. You may need to ask for a ‘double appointment‘ (20 mins).
Note. Possible spinal cord compression needs to be seen by your GP today. If this is not possible, go to A&E.
