Fatigue is a common symptom that we all experience at some point. It is characterized by extreme tiredness, exhaustion, lack of energy, and feeling unable to carry out usual daily activities.
There are two main types of fatigue:
Physical fatigue occurs after extended periods of physical activity, when muscles are unable to sustain power output. Lactic acid builds up, causing that "burning" feeling.
Mental fatigue sets in when the mind can no longer focus well or process information as sharply after long periods of cognitive or emotional strain. Mental exhaustion makes even simple tasks more difficult.
What causes fatigue?
Many factors can contribute to general fatigue, including:
Lack of good quality sleep
Poor nutrition or hydration
Stress, anxiety, depression
Underlying health conditions like anemia, thyroid issues
Side effects of medications
Lifestyle factors such as lack of physical activity, excessive screen time
How is fatigue diagnosed?
Doctors first do a physical exam and ask about lifestyle, habits, symptoms. They may recommend blood tests to check for potential causes like vitamin deficiencies or illnesses.
How is fatigue treated?
Treatment aims to find and address the root cause:
Prioritizing sleep hygiene - sticking to consistent bed/wake times
Eating a balanced diet and staying hydrated
Getting regular exercise to reduce stress and improve energy
Managing health conditions with medications if necessary
Considering supplements like iron, B12, Vitamin D if deficient
Making lifestyle changes and finding adequate rest and relaxation is key. If fatigue persists, see your doctor to rule out any medical issues. Learning your limits and not overexerting yourself can help prevent fatigue from building up.
While tiresome, fatigue is usually manageable with some simple lifestyle tweaks and self-care. Paying attention to your mind and body's needs can go a long way towards keeping your energy reserves stocked up.
