Fatigue

What is fatigue?

Fatigue is defined as an overwhelming sense of tiredness, lack of energy, and feeling of exhaustion. It can have both physical and mental components. We all experience fatigue at some point, but when it becomes excessive, persistent, and interferes with daily life, it may indicate an underlying medical issue.

There are two main types of fatigue:

• Physical fatigue occurs after exertion, exercise, or a long day and is usually temporary and relieved by rest. Muscles may feel heavy or weak.


• Mental fatigue refers more to brain exhaustion. Symptoms include poor concentration, forgetfulness, lack of motivation, irritability, and sleepiness. Mental fatigue can occur even without physical exertion.

Common causes of fatigue include:

• Lack of sleep


• Stress


• Medical conditions like anemia, diabetes, thyroid disorders


• Depression


• Grief


• Poor diet


• Dehydration


• Medications


• Excessive alcohol intake


• Pregnancy

If you struggle with persistent, unexplained fatigue that is interfering with work, relationships or quality of life, I highly recommend getting checked out by a doctor to identify any underlying causes. Blood tests can check for issues like vitamin deficiencies, infections, thyroid disorders etc.
