Immanuel's Key take aways :

Fatigue is a persistent tiredness or lack of energy caused by various factors, including lifestyle, underlying health conditions, or nutrient deficiencies.

Chronic fatigue syndrome (CFS) is a severe form of fatigue that lasts for months and disrupts daily life.

Addressing fatigue involves identifying the root cause, possibly related to deficiencies, sleep quality, stress, or chronic health issues.

‍

What Is Fatigue?

Fatigue is more than just feeling tired after a long day. It’s a prolonged and persistent sense of exhaustion that doesn’t improve with rest or sleep. While occasional fatigue is common, persistent fatigue may indicate an underlying issue. For a detailed overview, visit the NHS Fatigue Overview.

Fatigue can manifest physically, mentally, or both. Symptoms may include lethargy, reduced focus, muscle weakness, and difficulty completing daily activities.

Symptoms of CFS:

FAQs

What deficiency causes fatigue?

Iron deficiency is a leading cause of fatigue, often due to anaemia. Other deficiencies, such as vitamin D or B12, can also contribute to low energy levels. For details, see the NHS Anemia Guide.

‍

How is chronic fatigue syndrome different from regular fatigue?

Chronic fatigue syndrome is a medically diagnosed condition marked by severe fatigue that lasts for six months or more and significantly impairs daily life. Regular fatigue is temporary and often resolves with rest or lifestyle changes. Learn more from the CDC Chronic Fatigue Syndrome Guide.

‍

Can stress cause fatigue?

Yes, prolonged stress can lead to physical and mental fatigue by exhausting the body’s energy reserves and disrupting sleep patterns.

Conclusion

Fatigue, whether caused by lifestyle factors, nutrient deficiencies, or underlying conditions, can significantly affect your quality of life. Identifying the root cause and adopting lifestyle changes like improving sleep hygiene, managing stress, and maintaining a balanced diet can help restore energy levels.
