Exhaustion (fatigue) is more than feeling drowsy. Having trouble getting out of bed in the morning and being unable to do routine activities effectively may indicate that the person is exhausted.

Exhaustion may be divided into two types: physical and mental.

A fatigued person may find it physically difficult to do simple activities like ascending the stairs. One of the symptoms of physical exhaustion is muscle weakness. A strength test may be needed to identify the precise reason.

Mental fatigue may make it difficult to concentrate on tasks and maintain attention for extended periods. People with this type of fatigue may feel sleepiness or struggle to remain awake at work.

Despite the fact that physical and mental exhaustion are distinct, they often coincide. Physical fatigue caused by continuous activity may lead to mental exhaustion as well.

Fatigue may be caused by a lack of sleep, especially if the condition continues for an extended length of time.

Eating a well-balanced diet and exercising regularly may help feel less fatigued in the long term. In addition to restorative sleep, addressing the underlying cause of tiredness, such as sleep deprivation or a medical condition, may be beneficial.

Many nations have seen an increase in pandemic fatigue in recent times of the Covid pandemic. Individuals are less inclined to take suggested measures to protect themselves and others from disease. Pandemic fatigue is a gradual lack of desire to engage in suggested preventive measures.


Following are the causes of exhaustion:

Infection: A variety of viral and bacterial illnesses may produce severe fatigue that lasts for many days. Among the viral diseases that may produce this symptom are influenza, Lyme disease, and acute hepatitis. Severe bacterial infections of the lungs, kidneys, heart, bones or circulatory system may induce prolonged tiredness. Along with the fever, there are often additional localized signs and symptoms.

Stress: Chronic, severe psychosocial stress often causes extreme fatigue. Job loss, financial problems, separation or divorce, serious sickness in the family, and the death of a loved one may create considerable stress and fatigue. Anxiety and despair, among other mental health problems, may cause sudden, incapacitating exhaustion that is difficult to manage.

Sudden extreme fatigue is more likely to be caused by an acute disease than by a chronic condition. The presence of related indications and symptoms helps to narrow the range of potential causes.

Chronic fatigue syndrome (CFS) is persistent tiredness or severe exhaustion that does not go away with rest. It cannot be explained by an underlying medical disease or sickness. The condition’s cause has been hypothesized to be either a viral infection or psychological stress, or a mix of the two. Since there are no diagnostic tests for CFS, determining whether or not someone has the disease is impossible. Your doctor will need to rule out any other potential reasons for your tiredness before establishing a diagnosis. Individuals with chronic fatigue suffer muscle discomfort, headaches, sensitive lymph nodes, and a persistent sore throat. These symptoms may last for weeks, months, or even years.

Adrenaline fatigue is a term used to explain medical conditions that represent a collection of unspecific symptoms including body pains, tiredness, anxiety, and sleep difficulties, as well as stomach disorders. The adrenal glands are in charge of generating a wide range of essential hormones. Adrenal insufficiency is described as the adrenal glands’ inability to produce one or more of these hormones. It may be caused by an illness or surgery that has damaged the adrenal glands.

Some of the indications and symptoms of adrenal insufficiency are:

·         Fatigue

·         Aches and pains in different bodily areas

·         Weight reduction

·         Low blood pressure

·         Light-headedness

·         Hair loss

Muscle fatigue is a symptom that occurs as your muscles’ capacity to execute their function deteriorates over time. It is most often felt after periods of great effort or activity, and it is accompanied by weariness and exhaustion. You grow weaker when your muscles fatigue.

When to see a doctor

If your fatigue or tiredness becomes more severe or lasts longer than a week or two, you should seek medical care. The existence of other symptoms such as a low-grade temperature, shortness of breath, or a lack of appetite suggests that you are suffering from an underlying disease or infection that needs to be addressed immediately. Consult your physician if you have any other symptoms in addition to fatigue, such as blood in your stool, changes in the way your stomach works, heavy periods, or a lump.
