With such seemingly harmless symptoms as fatigue, lethargy, drowsiness, each of us is probably familiar. In some people, they occur exclusively in the off-season due to a lack of vitamins and nutrients. However, for many, these symptoms do not disappear even with the onset of spring, but on the contrary, they become even more aggravated, worsening the working capacity and the condition of the body as a whole. In this article, we will look at the main causes that cause fatigue, lethargy, and drowsiness.
Neurasthenia
The signs we are considering quite often indicate diseases associated with the exhaustion of the nervous system. The main symptoms of neurasthenia are lethargy, weakness, fatigue, daytime sleepiness, nausea, dizziness, migraine. Moreover, even after rest, the above symptoms do not disappear. Patients suffering from neurasthenia are very sensitive to bright light, noise, loud sounds. Quite often they complain of bad memory. A similar disease can occur as a result of starvation, increased physical exertion, nervous stress, constant lack of sleep, etc.
Chronic Fatigue Syndrome
With this disease, the patient's performance is almost halved. At the same time, any cases that a person previously coped with quite easily, seem unbearable for him. Signs of the disease are as follows: causeless exhaustion, muscle weakness, joint pain, forgetfulness, lethargy, fatigue, drowsiness. The causes of the disease are due to the peculiarities of modern life. A tense rhythm, psychological stress, constant lack of sleep and overwork, a large amount of information - everything gradually accumulates, causing a constant feeling of fatigue. In addition, prolonged sitting at the computer in the absence of physical activity entails tension in the muscles of the shoulders, back, and lower back. Therefore, it is workaholics who most often suffer from this syndrome.
Endocrine disruption
Symptoms of "fatigue, drowsiness, apathy" very often occur in women during menopause. At the same time, against the background of the main manifestations, irritability, loss of strength, excessive tearfulness, and a decrease in intellectual and physical abilities often appear. Daytime sleepiness is often the result of nocturnal insomnia. There are times when severe depression develops against the background of endocrine disruptions.
Acute CNS Poisoning
Fatigue, lethargy, drowsiness may also indicate intoxication resulting from depression of the central nervous system by chemical, bacterial or plant poisonsorigin. At the same time, even some substances that have an exciting effect on the central nervous system (alcohol), at high concentrations, can cause exhaustion, and in more severe cases, coma. The main symptoms can be supplemented by headache, vomiting, weakness, nausea. It is difficult for the patient to swallow, he has double vision. Often in such cases, pupillary constriction is observed.
Hidden Depression
Characterized by sleep disturbance. A person can stay awake for a long time in the evening, and in the morning it is difficult for him to get out of bed. In this case, as a rule, fatigue, lethargy, drowsiness are observed in the first half of the day. Often, depression is accompanied by physical disorders, such as heart palpitations, constipation, chest pain.
