Chronic fatigue is a condition characterized by extreme and persistent tiredness, weakness, or exhaustion that lasts for at least 6 months or longer. This type of fatigue impairs normal daily functioning and doesn't improve much with rest. While most people experience occasional tiredness, chronic fatigue is more severe and doesn't get better with sleep or rest.
Chronic fatigue can have many underlying causes, including:
- Chronic fatigue syndrome (CFS): Also called myalgic encephalomyelitis (ME), CFS is a complex disorder characterized by severe and disabling fatigue lasting at least 6 months that is not improved by rest and is accompanied by other symptoms like muscle pain, impaired memory, and sore throat. The cause is unknown but may involve immune system dysfunction, viral infections, stress, or brain abnormalities.
- Sleep disorders: Conditions like insomnia, sleep apnea, narcolepsy, and restless leg syndrome can lead to non-restorative sleep and next-day fatigue. Treating the underlying sleep disorder often improves fatigue.
- Anemia: Having low levels of red blood cells reduces oxygen delivery to tissues and causes fatigue. Iron deficiency is a common cause.
- Hypothyroidism: When the thyroid gland is underactive, it doesn't make enough thyroid hormone, leading to fatigue and weight gain. Thyroid medication helps normalize levels.
- Depression: Feeling emotionally drained or apathetic are hallmark symptoms of depression, along with fatigue. Antidepressants and counseling help treat depression.
- Heart disease: Heart conditions like congestive heart failure reduce blood flow and oxygen, leaving you exhausted. Treating the heart disease can alleviate fatigue.
- Cancer: Cancer causes fatigue both directly due to the disease and as a side effect of treatments like chemotherapy. Controlling cancer may improve fatigue.
- Medications: Many prescription and over-the-counter drugs can cause fatigue, like antihistamines, blood pressure medications, and some antidepressants. Changing medications may help.
Diagnosing chronic fatigue involves blood tests to check for things like anemia and thyroid problems, sleep studies if a sleep disorder is suspected, and ruling out other conditions. Treating the underlying cause, when known, is key. Lifestyle remedies like daily exercise, stress management, proper sleep habits, and dietary changes can also help boost energy levels.
