Cracking the Code of Fatigue: Understanding the Most Common Reasons for Tiredness
In this insightful article, we'll delve into the phenomenon of fatigue — what it is, its common causes, how to identify them, and most importantly, effective ways to address and overcome them.
Wikipedia defines fatigue as an intense state of tiredness or exhaustion affecting an individual's physical and mental aspects. This condition is marked by a noticeable decline in energy, motivation, and alertness. Despite these symptoms being widespread, they are often downplayed and underestimated.
In a recent CDC article from 2022, it was reported that a substantial 13.5% of adults aged 18 years and older experienced feeling very tired or exhausted most days or every day in the past 3 months, highlighting the prevalence of this issue.
What is Fatigue?
Fatigue extends beyond mere tiredness; it's a pervasive state of exhaustion that significantly impacts daily life.
Common Causes of Fatigue
Even though there are many possible reasons for feeling tired, let's keep it simple and look at the common ones. Understanding these main causes is important. Here are some common reasons:
Low Vitamin D: Research from the Nature Journal indicates that a significant number of people in different parts of the world have insufficient Vitamin D levels. Estimates show that 24% in the US, 37% in Canada, and 40% in Europe have 25(OH)D levels less than 50 nmol/L (or 20 ng/ml). This emphasizes the widespread nature of the problem.
Thyroid Hormone Levels: Especially in females, have a significant impact. According to data from the National Health and Nutrition Examination Survey (NHANES), the prevalence is reported to be 17% in females and 5.9% in males. Moreover, these figures are on the rise.
Other Factors: Beyond the usual suspects, conditions such as anemia, diabetes, kidney failure, liver failure, heart failure, and cancer can also play a role in causing fatigue.
Identifying and Treating Fatigue Causes
Identification:
Simple blood tests conducted by your Family Doctor can pinpoint common causes. For less common contributors, a comprehensive history, examination, and additional tests are essential.
Treatment:
Vitamin D Deficiency: Swift improvement can be achieved by supplementing with Vitamin D.
Hypothyroidism (Low Thyroid Hormone Level): Prescription medications effectively address low thyroid hormone levels.
Conclusion:
