  9. Fatigue (material) - Wikipedia

    Fatigue has traditionally been associated with the failure of metal components which led to the term metal fatigue. In the nineteenth century, the sudden failing of metal railway axles was thought to be caused by the metal crystallising because of the brittle appearance of the fracture surface, but this has since been disproved.

    Fatigue is generally defined as a feeling of lack of energy and motivation that can be physical, mental or both. Fatigue is not the same as drowsiness, but the desire to sleep may accompany fatigue. Apathy is a feeling of indifference that may accompany fatigue or exist independently. In addition, individuals often describe fatigue using a variety of terms including weary, tired, exhausted, malaise, listless, lack of energy and feeling run down.

    However, in contrast to fatigue that occurs with some diseases and syndromes, normal fatigue in healthy individuals is quickly relieved in a few hours to about a day when the physical or mental activity is reduced. Also, people occasionally experience fatigue after eating (sometimes termed postprandial depression), which can be a normal response to food, especially after large meals and this may last about 30 minutes to several hours. Generally, the prognosis for fatigue is good, because many of the causes are relatively easy to treat. However, the prognosis decreases if the person has difficulty in complying with treatments or has underlying conditions (for example, advanced diabetes or COPD) that are severe and slowly progress.

    In addition to the many terms attributed to \\"fatigue,\\" there are further problems with the terminology used to describe fatigue. There are several \\"fatigue syndromes\\" that occasionally appear in the medical literature. For example, Epstein-Barr chronic fatigue syndrome, post viral infection fatigue syndrome, and adrenal fatigue syndrome are among the most commonly seen. However, many physicians do not recognize these as syndromes because the criteria used to define them as syndromes are too diffuse and many consider the associated fatigue (sometimes chronic fatigue) as either a symptom or complication of the underlying associated diseases. However, there is a well-defined chronic fatigue syndrome recognized by specific criteria. Basically, two sets of criteria need to be met to establish a diagnosis of chronic fatigue syndrome:

    1. Have severe chronic fatigue for at least six months or longer with other known medical conditions (whose manifestation includes fatigue) excluded by clinical diagnosis; and

    2. Concurrently have four or more of the following symptoms, for post-exertional malaise, impaired memory or concentration, unrefreshing sleep, muscle pain, multi-joint, and pain without redness or swelling, tender cervical or axillary lymph nodes, sore throat, and headache. Consequently, people and their health-care professionals need to spend some time together to clearly determine whether or not the problem or symptom is truly fatigue, and if it is, any associated symptoms that may accompany the fatigue should be explored. Fatigue is a symptom that usually has some underlying cause. Fatigue may be described by people in different ways, and may include some combination (both mental and physical) include weakness, lack of energy, constantly tired or exhausted, lack of motivation, difficulty concentrating, and/or difficulty starting and completing tasks. Other symptoms such as fainting or loss of consciousness (syncope), near-syncope, rapid heartbeat (palpitations), dizziness or vertigo may also be described as part of the fatigue experienced by the affected individual. The presence of these symptoms may actually help lead a health care practitioner to discover the underlying cause(s) of the fatigue. Associated symptoms (not all inclusive as answers may trigger other questions) fever, pain, nausea, vomiting, diarrhea, blood in urine or stool, shortness of breath, chest pain, constipation, muscle cramps or aches, easy bruising, cough, changes in thirst or urination, inability to sleep lying flat, inability to walk up more than one flight of stairs, changes in appetite, loss or gain of weight, menstrual irregularities, swollen legs, and/or mass in breast.

    The potential causes of fatigue are numerous. The majority of diseases known to man often list fatigue or malaise as possible associated symptoms. This is complicated by the fact that fatigue can occur in normal healthy individuals as a normal response to physical and mental exertion. However, normal fatigue may begin to become abnormal if it becomes chronic, extreme or prolonged fatigue; usually this occurs when a person experiences chronic or prolonged physical or mental exertion. For example, unusually hard physical or mental exertion for one day can result in normal fatigue that may last about a day or sometimes more, depending on the exertion level, while daily unusually hard physical or mental exertion may result in prolonged fatigue (usually greater than 24 to 48 hours). This latter situation may develop into abnormal fatigue.

    Sleep Problems: sleep apnea; reflux esophagitis; insomnia; narcolepsy; work shift work or work shift changes; pregnancy; extra night hours at \\"work\\" Other: cancer; rheumatology illnesses such as rheumatoid arthritis and systemic lupus; fibromyalgia; chronic fatigue syndrome; normal muscle exertion; obesity; chemotherapy and radiation therapy

    Does the level of fatigue remain constant throughout the day? Does the fatigue get worse as the day goes on, or does the fatigue begin at the start of the day? Is there a pattern to the fatigue (time of day or time of year like the holidays)? Does the fatigue occur at regular cycles? How is the person's emotional state? Does the person feel unhappiness or disappointment in life? Sleep pattern determination. How much sleep is the person getting? During what hours does the person sleep? Does the person awake rested or fatigued? How many times does the person awake during sleep? Are they able to fall back asleep? Does the person get regular exercise? Any exercise? Has the person had any new stressors in their life? Change in relationships, jobs, school, or living arrangements? What is the person's diet? Is there a high intake of coffee, sugar, or excessive amounts of food?

    After obtaining the history, a physical exam will be performed, focusing on the patient's vital signs (weight, blood pressure, heart rate, temperature, breathing rate). The doctor will observe the patient's general appearance, listen to the heart, lungs, and abdomen, and may perform a pelvic and rectal exam. The doctor may order some of the following tests depending on the suspected underlying cause of the fatigue.

    The treatment for fatigue depends upon the cause. Some treatments for conditions that cause fatigue include medications, antibiotics, vitamins, and exercise. Medical treatment of fatigue depends on the treatment of its underlying cause(s). Fortunately, many causes of fatigue may be treated with medications, for example, iron supplements for anemia, medications and machines to help sleep apnea, medications to control blood sugar, medications to regulate thyroid function, antibiotics to treat infection, vitamins, and/or recommendations for dietary changes and a sensible exercise program. Again, treatment of the underlying cause(s) is the key to treatment of the symptom of fatigue.

    Fatigue prevention (both physical and mental) is possible in many people. Prevention of the underlying cause in almost every situation will prevent the symptom of fatigue.
