Fatigue is a common symptom that can be caused by various factors working in combination, such as medical conditions, illnesses, unhealthy lifestyle choices, workplace problems, grief, and more. Here are some of the most common causes of extreme fatigue:
-
Medical conditions: Unrelenting exhaustion may be a sign of an underlying illness or condition, such as flu, glandular fever, chronic fatigue syndrome, thyroid disorders, heart disease, or diabetes.
-
Lifestyle-related causes: Alcohol or drugs or lack of regular exercise can lead to feelings of fatigue.
-
Workplace-related causes: Workplace stress can lead to feelings of fatigue.
-
Psychological causes: Fatigue is a common symptom of mental health problems, such as depression and grief, and may be accompanied by other signs and symptoms, including irritability and lack of motivation.
-
Sleep disorders: Certain sleep disorders can cause long-term exhaustion and extreme fatigue, such as sleep apnea.
-
Prescription medications: Certain prescription medications can cause fatigue, including antidepressants, antihistamines, and blood pressure medications.
-
Infections: Many infections can cause fatigue, including the flu, glandular fever, and HIV.

Heart and lung conditions: Fatigue can be a symptom of cardiovascular and lung conditions such as heart failure, COPD, and asthma.

Chronic pain: People with chronic pain may wake up frequently throughout the night, leading to persistent tiredness and fatigue.

Postural orthostatic tachycardia syndrome (POTS): POTS is a little-known cause of extreme fatigue that is frequently missed and misdiagnosed. It is a condition that affects blood flow in the body and can cause fatigue, dizziness, and other symptoms.
