Fatigue

DEFINITION

Nearly everyone struggles with being overtired or overworked from time to time. Such instances of temporary fatigue usually have an identifiable cause and a likely remedy.

 

Chronic fatigue, on the other hand, lasts longer and is more profound. It’s a nearly constant state of weariness that develops over time and diminishes your energy and mental capacity. Fatigue at this level impacts your emotional and psychological well-being, too.

Fatigue isn’t the same thing as sleepiness, although it’s often accompanied by a desire to sleep — and a lack of motivation to do anything else.

In some cases, fatigue is a symptom of an underlying medical problem that requires medical treatment. Most of the time, however, fatigue can be traced to one or more of your habits or routines.

CAUSES

Taking a quick inventory of the things that might be responsible for your fatigue is the first step toward relief. In general, most cases of fatigue may be attributed to three areas: lifestyle factors, medical conditions or psychological problems.
Lifestyle factors

Feelings of fatigue often have an obvious cause, such as:

  • Alcohol use or abuse
  • Caffeine use
  • Excessive physical activity
  • Inactivity
  • Lack of sleep
  • Medications, such as antihistamines, cough medicines and cold remedies
  • Unhealthy eating habits


Psychological conditions
Fatigue is a common symptom of mental health problems, such as:

  • Anxiety
  • Depression
  • Grief
  • Stress


Medical conditions
Unrelenting exhaustion may be a sign of a medical condition or underlying illness, such as:

  • Acute liver failure
  • Anemia
  • Cancer
  • Chronic fatigue syndrome
  • Chronic kidney disease
  • COPD
  • Emphysema
  • Heart disease
  • Hyperthyroidism (overactive thyroid)
  • Hypothyroidism (a thyroid disorder)
  • Medications, such as prescription pain medications, heart medications, blood pressure medications and some antidepressants
  • Obesity
  • Restless legs syndrome
  • Sleep apnea
  • Type 1 diabetes
  • Type 2 diabetes

WHEN TO SEE A DOCTOR

Schedule a doctor’s visit

Call for an appointment with your doctor if your fatigue has persisted for two or more weeks despite making an effort to rest, reduce stress, choose a healthy diet and drink plenty of fluids.

Seek immediate medical attention
Get someone to take you to an emergency room or urgent care if fatigue is accompanied by:

  • Abnormal bleeding, including bleeding from your rectum or vomiting blood
  • Severe abdominal, pelvic or back pain
  • Severe headache
  • Call 911 or your local emergency medical service
  • Get emergency help if your fatigue is related to a mental health problem and your symptoms also include:
  • Thoughts of harming yourself or of suicide
  • Concern that you may harm someone else
  • Also get emergency care if your fatigue is accompanied by any of the following:
  • Chest pain
  • Shortness of breath
  • Irregular or fast heartbeat
  • Feeling that you might pass out
