There are many potential causes of fatigue. Fatigue is a possible symptom of most diseases.

Doctor

Medical causes of fatigue can cause constant exhaustion with additional symptoms. There are a number of conditions that cause fatigue. If you experience prolonged periods of fatigue, speak with your doctor to determine the root cause.

The medical causes of fatigue can be classified into broad categories of diseases. Some of these categories of diseases are:

  • Metabolic / Endocrine : Conditions such as anemia, diabetes, hormonal imbalances, liver or kidney disease.
  • Infections : flu, tuberculosis or malaria.
  • Cardiac (heart) and pulmonary (lung) : congestive heart failure, chronic obstructive pulmonary disease (COPD), arrhythmias, and asthma.
  • Mental health : depression and anxiety
  • Sleep problems : sleep apnea, insomnia, and restless leg syndrome.
  • Vitamin deficiency: vitamin D deficiency, vitamin B12 deficiency, or iron deficiency.
  • Other conditions : cancer and rheumatic / autoimmune diseases.
  • Medicines you take to treat other conditions can also cause fatigue. These can include antidepressants and anxiety medications, sedatives, some blood pressure medications, chemotherapy, radiation therapy, and steroids.

Lifestyle

Lifestyle reasons are often related to sleep disorders, diet, lack of regular exercise, alcohol or drug use, or other factors.

Sleep disturbances : If you don't get enough sleep, sleep too much, or wake up at night, you may experience fatigue during the day.

Diet – If you eat a lot of carbohydrate, fat or instant foods, sugary foods and drinks, or caffeinated beverages, you are not providing your body with enough fuel or nutrients to function better. What's more, these foods can cause a burst of energy that passes quickly, causing a "crash" and increased fatigue.

Alcohol and drugs . Alcohol is a depressant that slows down the nervous system and disrupts sleep. Cigarettes and caffeine stimulate the nervous system and cause trouble falling asleep and sleeping.

Lack of regular activity – Physical activity is known to improve your health and well-being, reduce stress, and increase energy levels. It will also help you sleep better and reduce daytime fatigue.

Individual factors : personal or family illness or injury, too much commitment, and financial problems can make a person feel tired.

Stress

The causes of stress can be related to a stressful work environment, toxic relationships, or mental health problems such as depression and anxiety.

Work- related fatigue : People who work night shifts may experience fatigue during the day. This is because the human body is designed to sleep at night and the person working the night shift disrupts their body's circadian clock. Improper workplace practices such as long hours, manual labor, overtime, noisy workplaces, constant concentration, and repetitive tasks also contribute to fatigue. Burnout and other stressors in the workplace, such as a heavy workload, conflict with a boss or co-workers, workplace bullying, or threats to job safety, can all contribute to fatigue.

Mental health : Depression, anxiety, and pain can lead to fatigue. These conditions drain the body physically and emotionally and cause severe fatigue.

Diagnostics

Fatigue manifests itself in a number of symptoms and is often caused by a combination of several factors. This makes diagnosis difficult. Therefore, your healthcare provider will try to determine the cause of your fatigue through a series of tests, including the following.

Medical history : Your healthcare provider will ask you about recent stressful events (good and bad) in your life, such as having a baby, surgery, job stress and family problems, or other symptoms you have experienced in addition to fatigue.

Physical exam : A physical exam will help your doctor detect signs of illness. Your healthcare professional may also ask you about your current diet and lifestyle.

Tests : Tests may include blood tests, urinalysis, X-rays, and other images. Your healthcare provider will want to rule out physical causes.
