Feeling constantly exhausted? You're not alone. Many people blame their fatigue on lack of sleep, but a doctor has revealed there could be other, more surprising reasons behind your tiredness.
Hidden Health Issues
Dr. Sarah Brewer, a GP and health writer, explains that chronic fatigue isn't always caused by poor sleep. Underlying health conditions such as anaemia, thyroid disorders, or even vitamin deficiencies could be draining your energy.
Common Culprits:
- Anaemia: Low iron levels reduce oxygen flow, leaving you sluggish.
- Thyroid Problems: An underactive thyroid slows metabolism, causing fatigue.
- Vitamin D Deficiency: Lack of sunlight can lead to low energy and muscle weakness.
Lifestyle Factors
Even if you're getting enough sleep, poor diet, dehydration, and stress can leave you feeling worn out. Dr. Brewer advises:
- Stay hydrated—dehydration causes fatigue.
- Eat balanced meals—skipping carbs or protein affects energy.
- Manage stress—cortisol spikes can exhaust you.
When to See a Doctor
If fatigue persists despite lifestyle changes, consult a GP. Persistent tiredness could signal serious conditions like diabetes or heart disease.
Simple blood tests can identify deficiencies or hormonal imbalances, helping you regain your energy.
