10 Health Symptoms You Should Never Ignore – and How a Simple Blood Test Can Help

When it comes to your health, listening to your body is essential. Many people dismiss symptoms as “normal” or something that will pass on its own. However, certain signs can point to underlying conditions that may need medical attention. The good news is that a straightforward blood test can often provide the clarity you need.

At Private Blood Tests London, we offer fast, confidential and accurate blood testing services to help you understand your health and take action early.

1. Constant Fatigue

Feeling tired occasionally is normal, but ongoing exhaustion could signal anaemia, thyroid issues, or diabetes. A Thyroid Function Test can reveal whether your fatigue is linked to an underlying condition.

2. Unexplained Weight Changes

Sudden weight gain or loss without changes to diet or exercise may indicate hormonal imbalances, diabetes, or thyroid disorders. A Diabetes Profile or MaleHormone Screening or Female Hormone Screening can provide clarity.

3. Frequent Infections

If you catch colds easily or struggle to recover from minor illnesses, your immune system may be weakened. Blood tests can check your white blood cell levels and detect deficiencies.

4. Persistent Skin Problems

Acne, rashes or sudden skin changes can be related to allergies, liver issues, or hormonal imbalances. A Liver Function Test or allergy-related blood test can be helpful.

Explore our range of private blood tests to find the right option for you.

5. Shortness of Breath

If you often feel breathless, even at rest, it could be linked to anaemia or cardiovascular problems. A Cardiovascular Risk Profile can help assess your heart health.

6. Hair Loss

Excessive hair shedding may be caused by iron deficiency, thyroid problems, or hormonal changes. Blood testing for iron, vitamin D, and thyroid hormones can highlight possible causes.

7. Persistent Cough

A cough lasting more than a few weeks shouldn’t be ignored. Blood tests can support further investigations into infections, allergies, or other respiratory issues.

8. Mood Changes and Brain Fog

Low mood, anxiety, or difficulty concentrating can sometimes be linked to vitamin deficiencies, thyroid conditions, or hormonal changes. A Vitamin Profile or Thyroid Function Test can provide valuable insights.

9. Abdominal Pain or Digestive Issues

Bloating, cramps, or irregular bowel movements may be caused by food intolerances, coeliac disease, or liver and kidney issues. Blood testing can guide you towards the right treatment.

10. Changes in Urination

Frequent urination, pain, or dark-coloured urine can be signs of diabetes or kidney conditions. A Kidney Function Test or Diabetes Profile can help detect early concerns.
