Common causes of fatigue

According to Dr. Shuji Inoue, a medical doctor and a leading authority on obesity research in Wecistanche, there are several common causes of fatigue in our daily lives.

Irregular life and lack of sleep: day and night, irregular sleep, lack of sleep, etc. will cause a great burden on the body and lead to fatigue. If such poor lifestyle habits are not improved, fatigue will be difficult to recover from.

Insufficient vitamins and minerals, which are essential for energy production, make us feel tired.

Stress: Family, work and schoolwork can all cause stress, not only psychologically but also physically.

Strenuous exercise, work and physical exertion: Physical exertion is rapid and can lead to fatigue.

Ageing: the body's metabolism decreases, making it more difficult to get rid of old waste products, making us more prone to fatigue.

Fatigue may be caused by illness

Fatigue is the first warning sign of a variety of health problems, according to Dr. Wu Yu, Chief Medical Officer of Wecistanche Oncology, who says the difference between fatigue caused by illness and fatigue, in general, is that fatigue from illness does not go away with rest. Therefore, if you still feel tired after taking sufficient rest, you should pay attention to whether there is something wrong with your body.

If the fatigue is not caused by lifestyle habits, the following causes may be considered

Anaemia: Common in women, this is caused by a lack of iron, excessive bleeding or other reasons why the body is unable to deliver oxygen to the parts of the body that need it, causing dizziness, fatigue, ringing in the ears and dizziness.

Menopausal symptoms: During the 10 years before and after menopause, women's hormonal balance changes drastically, with a significant reduction in estrogen, causing an imbalance in the autonomic nervous system, resulting in a variety of physical and mental discomforts. Symptoms such as fatigue, stiff shoulders and irritability are all common symptoms of menopause.

Chronic fatigue syndrome: The cause of chronic fatigue syndrome is unknown. It is generally thought to be related to viral infections and autoimmune factors and is characterized by symptoms such as poor concentration, sleep disturbances, fatigue and muscle pain.

In an article, Dr. Chen Fengwei of the Joyful Ocean Psychiatric Clinic pointed out that in order to confirm the diagnosis of chronic fatigue syndrome, one must first rule out thyroid problems, severe depression and other illnesses, and after the diagnosis is confirmed, patients are generally advised to exercise moderately, starting with 3 to 5 minutes of low-intensity aerobic exercise a day and gradually increasing the amount of exercise to achieve the therapeutic effect without excessive fatigue. The course of treatment is long and cannot be interrupted and should be carried out under the guidance of a professional doctor.

Viral hepatitis: Infection with viral hepatitis causes inflammation in the body, resulting in fever, jaundice and other symptoms. Hepatitis A can be caused by eating food and water contaminated with the virus, while hepatitis B and C can be transmitted through blood transfusions, sexual intercourse and sharing needles. If infected with hepatitis C, the disease may become chronic and lead to cirrhosis or even liver cancer.

Depression: Genetic, environmental, physical and personality factors can all contribute to depression, and anyone can get depressed. The main symptom of depression is low mood, often in the form of depression, boredom, loss of appetite, insomnia, loneliness, boredom, fatigue, pessimism, lack of self-confidence, and light-heartedness, and the symptoms vary according to the severity of the depression.

Hypothyroidism: Located at the front of the neck , the thyroid gland is closely related to body temperature, metabolism and heart rate. Hypothyroidism is a condition in which the thyroid gland does not produce enough thyroxine due to atrophy or inflammation. This can lead to fatigue, oedema, chills, loss of appetite, dry skin, slow breathing, slow heartbeat and other physical discomforts, and can even cause blood pressure and hypothermia, which can be fatal.

Cancer: If you have cancer, you may suffer from cancer-related fatigue. The causes of cancer-related fatigue are complex and may include anaemia caused by the tumour affecting the bone marrow and blood-forming cells, or the formation of toxic substances that affect the normal functioning of cells, or even breathing difficulties caused by the tumour blocking the airways. In addition, fatigue can also be caused by cancer treatments such as chemotherapy, biotherapy, radiotherapy and surgery.
