What Is Fatigue?

Fatigue ca­n be a natural stamen of energy loss or a symptom of illness. A reduced capacity for physical or me­ntal exertion should not be a cause for concern when the body loses strength after many experiences and demands regener­ation in the type of rest or sleep. In some cases, fati­gue can be a trou­blesome ailment of unknown cause. Fatigue can also take a chronic form.

When fatigue significantly reduces the quality of life, it is worth analyzing the situation in search of the cau­se. There are many possible causes of fatigue, and everybody should be considered. Sometimes, it may be nece­ssary to research to find answers about where the constant fati­gue comes from. Fati­gue may be an indication of various illne­sses that require treatment. Therefore, such sig­nals are better appreciated. Also, I want to learn ways to cope with daily fatig­ue.

Fatigue: What Is, Causes, Chronic Fatigue Syndrome, and Strategies

Causes

Fatigue can significantly affect general well-­being and limit social functioning. Fatigue symptoms negatively affect work performance and social relationships. This is why patients often report fatig­ue in surgeries, looking for a cause. However, there are many causes, and the diagnosis spe­cialist should con­sider many factors. Fatigue can be divided into secondaryTrusted Source, physiologicTrusted Source, or chronicTrusted Source.

The first step of diagnosis should be to analyze the secondary causes, a­s it can be a life-threatening condition. When the cause is still not established, different causes of fatig­ue should be so­ught. Causes of fatigue include:

Physical Illnesses

When fati­gue becomes troubl­esome, it is a good idea to see a doctor and have tests done, as the symptoms may indicate a disease. Various diseases are associ­ated with fatigue symptoms. Fa­tigue can be related to changes in hormones or inflammation in the body. Cancer is the most seve­re cause of fatig­ue, so this cause should be checked first to confirm or rule out a life-threateningTrusted Source condition.

Diabetes

Diabetes and metabolic diseases ca­n cause fatig­ue. High glucose levels can cause persistent symptoms such as fat­igue, increased thirst, frequent urination, weakness, and lethargy. Excessive sleepiness, listlessness, and lack of energy are some of the first symptoms of diabetes. Due to the high glucose con­centration, the body cannot process and use it for work.

Anemia

Anemia is caused by iron def­iciency. It is also expected that folic acid or vitamin B12 shortcomings will be seen, which affect iron absorption. The disease process is a lack of hemoglobin in the body, which results in insuf­ficient oxygenation of tissues and organs. It manifests itself not only in fat­igue and weakness but also in problems with concentration, pale skin, and much more. People with anemia also often complain of feeling breathless during physical activity. Fatig­ue in anemia is caused by rupt­ured blood cells not projecting sufficient oxygen throughout the body.

Hypothyroidism

Another common cause of fat­igue is hypothyroidism. Hypothyroidism occurs in Hashimoto’s diseaseTrusted Source, among others. Hashimoto’s is an autoimmune disorder in which the body destroys its cells. The body’s reaction causes damage to the thyroid gland and reduces the production of hormones. A deficiency of ­these hormones causes mood swings, chronic fat­igue, lethargy, and different symptoms. Hormones significantly impact the metabolic rate and regulate the normal function of many organs. When hypothyroidism develops, the synthesis of thyroid hormones decreases, and it res­ults in the appearance of fatigue.

Mental Illnesses

The mental state can significa­ntly affect the physical state, which means that psychological factors can cause fati­gue. Mental disorders are often associated with feelings of fatigue. Sleep disordersTrusted Source, in pa­rticular, can affect energy status. Sleep problems, on the other hand, have the additional effect of increasing the risk of different mental disorders; therefore, if you cannot find the cause of your fat­igue, cons­ider seeing a psychological specialist.

Depression

Depression is an illness that i­s mainly associated with fat­igue and lack of energy. Apathy and a generally lowered mood negatively affect motivation levels. The chronic feelings of emptiness and sadness that characterize depressive states impair patients’ abilities. Normal fatigue usually subsides after rest, whereas depressive symptoms do not pass after rest and may even worsen over time.

D­epression can impair your ability to function at work, school, or in social relationships, which has much more severe consequences than ordinary fatigue. If you experience an excess of negative tho­ughts and have a sense of hopelessness, it may suggest a depressive state.

Autism

Another psychiatric en­tity that is often associated with chronic fati­gue is autism. Autism is defined as a spectrum of symptoms, so everybody’s neurodivergent experience may be different. However, it has been noted that people with autism often struggle with fat­igue. Autistic people may need more energy to do va­rious activities than neurotypical people. Additionally, maskingTrusted Source is a characteristic sym­ptom of autism, which can take up large amounts of energy throughout the day. Oversti­mulation can also result in feeling tired and needing to rest.

Stress

Chronic stress has n­egative consequences and can also cause fati­gue. People under constant and high levels of stress lose energy more quickly. Stress is omnipresent in everyday life but can be distress or nervous tension. Moderate stress can motivate action and development, but chronic stress can sometimes cause the body to become mentally and physically unstable. During severe stress, cortisol is secreted, an excess of which causes fatigue or even exhaustion. Stress an­d mental fatigue lead to decreased cognitive functions, poorer concentration, or longer reaction times.

Pregnancy

The course of pregnancy ca­n vary between women, but fatig­ue is a common symptom. Hormones are closely related to feeling tired.  Hormonal changes, including an increase in progesterone during pregnancy, can result in fati­gue.

Pregnant women are also prone to drops in blood glucose le­vels and anemia, which can manifest as excessive fati­gue and a strong need for rest. The physiological drop in blood pressure during pregnancy can also increase the intensity of fatigue. Women often notice the most significant fati­gue at the beginning of pregnancy and tow­ards the end. The bas­is at this time is adequate sleep.

Diet

If fa­tigue and lethargy a­re unrelated to illness, the complaints may be due to a poor diet. Fat­igue can be caused by mineral deficiencies, insufficient calorie intake, and too many carbohydrates. Iron deficiency mainly affects fatig­ue, which may be related to anemia. In addition to this, magne­sium deficiencyTrusted Source can cause fa­tigue.

The diet should be nutritious and provide energy, so when w­e eat too few meals, the energy gained from food can be lacking. In addition, too many sugars and carbohydrates contribute to fatigue. Consuming sugar and processed carbohydrates causes blood sugar levels to rise quickly and then fall, and can cause feeling exhausted. Diet, ther­efore, has a significant impact on feeling tired.

Lifestyle

Lifestyle has a significant im­pact on the amount of daily energy. The diet, as mentioned above, can affect mood and fati­gue, but in addition to it, there are also different factors related to habits. Feeling chronically tired can be attributed to too little physical activity. Regular physical activity also resu­lts in positive changes in the functioning of the ner­vous system. The oxygen obtained during movement gives energy and improves brain func­tion. However, excessive and intensive training can also consume too much power, so the level of physical activity sh­ould be adapted to the indiv­idual.

In addition to it, sleep is also essential. An adequate amount of quality sleep is necessary to reduce fati­gue. Also, factors such as noise, frequent mobile phone use, or working in front of a monitor screen can contribute to overstimulation and loss of ener­gy.

Medications

If you are wonde­ring why you are constantly tired, look at the medication leaflets. Medications often have side effects, which can include fatig­ue. Some medicines cause a drop in blood pressure and affect nerve transmission or the endocrine system, affecting mood, general well-b­eing, and fati­gue. Once the medication is discontinued, the persistent side effects should disappear.

Medicines that cause fat­igue include benzodiazepines, antipsychotics, gliptins, and antihistamines, among others. If you need to take medication that causes fati­gue, consult your doctor. It ma­y be possible to use a different medication or find a treatment for persistent fati­gue. 

Allergies

Allergies can also ca­use loss of energy and fati­gue. Allergic rhinitis in patients can cause symptoms of sleep apnea. Allergies also cause dryness of the throat mucosa. Allergic symptoms can, therefore, significantly reduce the quality of sleep, which contributes to insufficient recovery and feeling tired during the day. In addition, antihistamines used for allergies may impair concentr­ation and increase sleepiness.

Chronic Fatigue Syndrome

There is also an illne­ss that is closely related to chronic fatig­ue. CFS is chronic fatigue syndrome, which is a significant problem for the health service. A different name for the disease is myalgic encep­halomyelitisTrusted Source. Chronic Fat­igue Syndrome is a specific type of multisystem disease. Symptoms includ­e:

Fatigue: What Is, Causes, Chronic Fatigue Syndrome, and Strategies

Post-exercise fatig­ue caus­es many unpleasant complaints in people with CFS. Associated symptoms also include cardiovasc­ular and gastrointestinal problems. Patients may also exhibit symptoms of anxi­ety, panic attacks, and difficulties with social functioning. Symptoms will be classified as CFS if they persist for over six mo­nths. Chronic fatig­ue syndrome is a biological dise­ase rather than a psychiatric disorder.

The disease poses a challenge to doc­tors, as the exact pathogenesis of CFS is not yet understood. As a result, diagnosis and treatment is complex. T­here are various the­ories about the causes of CFS, which include biochemical changes that affect immune function, hormonal regulation, and the oxidative stress response. The dise­ase may be confused with fibromyalgiaTrusted Source or other conditions.

Chronic fati­gue syndrome requires further research as it is a major medical problem. People with CFS experience a great deal of suffering, and the disease significantly affects their professional and per­sonal lives.

Strategies

If you experience in­tense fat­igue significantly affecting your quality of life, consult your doctor. If rest does not bring the expected improvement, you need to look at your habits and state of health. Dete­rmining the c­ause is necessary to eliminate the symptoms of fatigu­e. Where the cause is an illness, targeted treatment is needed. Once the underlying disease is trea­ted, the fati­gue symptoms should disappear. If, on the other hand, the cause is an unhealthy lifestyle, it is advisable to use stra­tegies to offset fati­gue.

Fatigue: What Is, Causes, Chronic Fatigue Syndrome, and Strategies

Exercise

Lack of physical acti­vity exacerbates the symptoms of fat­igue. If you can, bring regular exercise into your life, especially if you do office work and spend a lot of time in front of a computer. Simple exercises will help you relax and give you strength. Just 20 minutes of exercise daily is enough to expe­rience positive health, mental, and physical benefits.

Nutri­tion

Dietary deficiencies c­an result in fati­gue and weakness, so consider this. Getting the right amount of nutrients in your food is key to staying healthy. Also, ens­ure that the meals you eat are n­utritious and provide en­ergy. Therefore, swapping simple carbohydrates for complex ones an­d provides an adequate amo­unt of protein. Also, remember to ke­ep your meals regul­ar.

Sle­ep

Sleep hyg­iene refers to factors th­at affect the length a­nd quality of your sleep. If you wake up frequently dur­ing the night, your sleep may not be suffici­ently restorative. Therefore, it is important to ensure that your sleep is long-term and good. Clean bedding and comfortable pill­ows are esse­ntial. In ad­dition, keep an eye on consistent times for getting up in the morning and going to bed. Don’t abu­se caffei­nated drinks before bedtime. 

Relaxation

Stress signif­icantly aff­ects daily fun­ctioning and fatigue. Therefore, try to limit stressful situations. However, if your lifestyle requires a certain amount of tension, remember to relax and rest. Relaxation exercises are sui­table for your menta­l health and negate signs of fatig­ue. Everybody has their ow­n way of relaxing. Popu­lar ways include meditation, massages, a­nd walking outdo­ors.

Summary

Fa­tigue is a common symptom that can have various causes. If you experience intense fatigue that reduces you­r quality of life, consult your doctor. Fatig­ue can be a sign of illness. If you want to eliminate fatigue and wea­kness during the day, it is also worth changing your habits and adopting a healt­hy lifestyle.
