10 Warning Signs You Should Never Ignore and When to See a Doctor
Warning signs you should not ignore and when to see a doctor can help you recognise when a symptom may require medical attention. Many health problems begin with symptoms that may seem minor at first. A headache may feel like an ordinary headache, tiredness may seem related to a busy schedule, and stomach discomfort may be mistaken for indigestion.
In many cases, these symptoms may have simple causes. However, some symptoms can indicate a health problem that requires prompt medical attention.
Knowing the warning signs you should not ignore can help you recognise when it may be time to consult a doctor and when immediate medical care may be necessary.
1. Chest Pain or Pressure
Chest discomfort can have many possible causes, including indigestion, muscle strain and heart-related conditions.
However, sudden or persistent chest pain or pressure should not be ignored, particularly when it occurs with:
- Shortness of breath
- Sweating
- Nausea or vomiting
- Dizziness or light-headedness
- Pain or discomfort spreading to the arm, shoulder, neck, jaw, stomach or back
When should you seek emergency care?
If chest pain is severe, persistent or associated with difficulty breathing, sweating, fainting or other concerning symptoms, seek emergency medical attention rather than waiting for it to disappear.
2. Sudden Difficulty Breathing
Breathlessness after strenuous physical activity may be temporary. However, sudden or severe difficulty breathing can require urgent medical attention.
Breathing difficulties can occur with conditions affecting the lungs, heart or blood vessels.
Pay particular attention when shortness of breath occurs together with:
- Chest pain
- Fainting or severe dizziness
- Coughing up blood
- A very rapid heartbeat
- Sudden weakness
When should you seek medical care?
Sudden or severe breathing difficulty should be assessed promptly. If breathing becomes extremely difficult or you feel that you cannot breathe normally, seek emergency medical care.
3. Sudden Weakness, Numbness or Difficulty Speaking
A sudden change in movement, speech or facial appearance can be a warning sign of stroke.
One useful way to recognise common stroke symptoms is FAST.
Remember FAST
- F – Face: Does one side of the face droop?
- A – Arms: Is there weakness or numbness in one arm?
- S – Speech: Is speech slurred, unclear or difficult?
- T – Time: Seek emergency medical help immediately.
Other possible stroke symptoms can include sudden vision problems, confusion, dizziness, difficulty walking or a sudden severe headache.
Why is immediate treatment important?
Stroke treatment can be time-sensitive. If stroke symptoms appear suddenly, do not wait to see whether they disappear.
Even if symptoms improve after a short period, medical assessment is important because temporary stroke-like symptoms can occur with a transient ischaemic attack (TIA).
4. A Sudden or Extremely Severe Headache
Most headaches are not caused by a serious medical condition. However, a headache that appears suddenly and is extremely severe, particularly when it is unlike headaches you have experienced before, should not be ignored.
A severe headache can sometimes occur with serious neurological conditions.
Warning symptoms associated with a severe headache
Seek urgent medical attention if a severe headache occurs with:
- Confusion
- Fainting
- Seizures
- Weakness or numbness
- Difficulty speaking
- Vision changes
- Repeated vomiting
- Loss of consciousness
When should you seek urgent care?
A sudden, extremely severe headache or a headache accompanied by neurological symptoms requires prompt medical evaluation.
5. Severe or Persistent Abdominal Pain
Abdominal pain is common and can result from many different conditions. Some causes may be minor, while others may require medical treatment.
You should pay attention to abdominal pain that is:
- Severe or sudden
- Persistent
- Getting progressively worse
- Associated with repeated vomiting
- Associated with significant bleeding
- Accompanied by fainting or severe weakness
- Accompanied by difficulty breathing
When should you consult a doctor?
Consult a healthcare professional if abdominal pain is severe, persistent, recurrent or associated with other concerning symptoms.
Avoid relying on self-diagnosis when pain is unusual or significantly different from what you normally experience.
6. Unexplained Weight Loss
Losing weight without deliberately changing your diet or physical activity can have many possible causes.
Possible causes can include digestive problems, hormonal conditions, nutritional issues, medication effects and other underlying health conditions.
Unexplained weight loss becomes particularly important to investigate when it occurs together with other symptoms.
Symptoms that may need evaluation
- Persistent loss of appetite
- Unusual tiredness
- Persistent pain
- Changes in bowel habits
- Persistent cough
- Unexplained bleeding
- Other significant changes in health
When should you see a doctor?
If you continue to lose weight without trying to do so, arrange a medical evaluation. A doctor can assess your symptoms and determine whether further tests are necessary.
7. Unusual or Unexplained Bleeding
Unexpected bleeding should not automatically be dismissed.
Examples include:
- Blood in the urine
- Blood in the stool
- Vomiting blood
- Coughing up blood
- Unusual vaginal bleeding
- Heavy bleeding that is difficult to control
There are many possible causes of abnormal bleeding. Some may be relatively minor, while others require medical investigation.
When is bleeding an emergency?
Heavy or uncontrolled bleeding, bleeding associated with fainting or severe weakness, or vomiting or coughing up significant amounts of blood requires urgent medical attention.
If you notice unexplained bleeding, consult a healthcare professional to determine its cause.
8. A Persistent Cough or Change in Breathing
Coughing is commonly associated with infections and other temporary conditions. However, a cough that continues for a long period, keeps returning or becomes worse should be evaluated.
Pay particular attention when a persistent cough is accompanied by:
- Shortness of breath
- Chest pain
- Coughing up blood
- Unexplained weight loss
- Persistent fever
- Significant fatigue
When should you consult a doctor?
Speak with a doctor if your cough does not improve as expected, keeps returning or is accompanied by other concerning symptoms.
A healthcare professional can determine whether you need further evaluation.
9. A New Lump, Swelling or Unusual Change
A new lump or swelling anywhere on the body deserves attention, particularly if it persists or changes.
Not every lump is cancerous. Many lumps can be caused by infections, cysts or other benign conditions.
However, it is difficult to determine the cause of a lump through self-examination alone.
What changes should you pay attention to?
Consult a doctor if a lump:
- Is new and unexplained
- Continues to grow
- Becomes painful
- Changes in appearance
- Persists for an unusual length of time
- Is associated with other unexplained symptoms
Why should persistent lumps be checked?
A healthcare professional can examine the lump and determine whether additional tests or investigations are necessary.
10. Persistent Fever, Night Sweats or Unusual Fatigue
Fever commonly occurs with infections and often improves as the underlying condition resolves.
However, a fever that persists, repeatedly returns or occurs alongside other unexplained symptoms should be evaluated.
Persistent or unusual fatigue can also have many possible causes.
When should you seek medical advice?
Consult a healthcare professional if you experience:
- Persistent or recurring fever
- Unexplained night sweats
- Persistent fatigue
- Unexplained weight loss
- Persistent pain
- Other significant changes in your health
A doctor can assess the combination of symptoms rather than looking at one symptom in isolation.
When Should You See a Doctor?
You should consider speaking with a doctor when a symptom:
- Continues longer than expected
- Keeps returning
- Gets progressively worse
- Is unusual for you
- Interferes with your daily activities
- Occurs together with other unexplained symptoms
- Causes significant concern
You do not necessarily need to wait until a symptom becomes severe before seeking medical advice.
A healthcare professional can review your symptoms, medical history and other relevant factors to determine whether you need an examination, laboratory tests, imaging or specialist consultation.
When Is Emergency Medical Care Necessary?
Some symptoms require immediate medical attention rather than waiting for a routine appointment.
Seek emergency medical care for symptoms such as:
- Severe or persistent chest pain
- Severe difficulty breathing
- Sudden symptoms of stroke
- Loss of consciousness
- Severe uncontrolled bleeding
- A sudden, extremely severe headache
- A seizure requiring emergency assessment
- Serious symptoms following a major injury
When you suspect a medical emergency, seek emergency medical help immediately.

If something feels different from your usual state of health, continues longer than expected, becomes worse or occurs together with other concerning symptoms, speaking with a healthcare professional can help identify the possible cause.
Early evaluation can help doctors determine whether further investigation or treatment is required.
