9 dangerous diseases that masquerade as fatigue

Health Tips

Yes, in our time everyone works a lot, overwork is a completely natural phenomenon. But if you took a couple of days off or even went on vacation for a week, and the fatigue still has not gone away, stop being shy! You need to go to the doctor and tell everything as it is.

In some cases, constant fatigue and apathy can be a sign of the development of serious diseases.

Iron-deficiency anemia

With anemia, the heart rate increases, it becomes difficult to breathe, the skin becomes pale. To determine anemia, you should consult a general practitioner who will prescribe studies and, if necessary, complex treatment, including medications and an appropriate diet. The risk of anemia is especially high in women of reproductive age (this is due to blood loss during menstruation).

Coronary artery disease

Sometimes a breakdown is the only symptom that portends the development of a myocardial infarction, which can occur absolutely painlessly. It makes sense to consult a cardiologist who will prescribe a comprehensive examination of the body. One of the most accurate diagnostic methods at the moment is coronary angiography, which will help determine the number, size of atherosclerotic plaques, as well as their location in the vessels of the heart.

Diabetes mellitus types 1 and 2

Glucose is a source of energy for the body. However, with insulin resistance, it cannot get into the cells – they do not receive energy, and now you feel as if the batteries are dead. Diabetes mellitus is an endocrine disease, to determine it, you need to consult an endocrinologist who will recommend appropriate tests and studies. It is worth noting that the risk of diabetes increases after age 40, with overweight, as well as if the next of kin suffer from this disease.

Oncological diseases

Constant fatigue and apathy may be the only manifestation of malignant tumors in the early stages! Start with a visit to a general practitioner who, after collecting an anamnesis, will prescribe basic tests and examinations, based on the results of which he will refer you to highly specialized specialists.

chronic fatigue syndrome

The causes of CFS are still under investigation. This issue should be dealt with in parallel by a therapist, a neuropathologist, an immunologist, an endocrinologist, since chronic fatigue syndrome can be a sign of more serious diseases that require diagnosis and treatment.

Vitamin B12 deficiency

This vitamin regulates the process of maturation of red blood cells. With a deficiency of vitamin B12, the normal development of blood cells is disrupted, which can lead to anemia and damage to the nervous system. To determine the deficiency of vitamin B12, at least a general blood test should be done: with a decrease in hemoglobin in red blood cells, we can talk about a lack of this vitamin in the body.

Vitamin D deficiency

This vitamin is associated with many receptors in different parts of the brain. Its deficiency can lead to the development of depression, weight gain, mood swings, hypertension. Vitamin D deficiency can be diagnosed with a blood test called the 25-hydroxyvitamin D test. The normal range for vitamin D in the body is between 30 and 74 nanograms per milliliter.


Sleep apnea is a disease characterized by pauses in breathing during sleep for more than 10 seconds. Due to the lack of oxygen, you are constantly waking up (quickly falling asleep again, you may not remember this) – and such interrupted sleep can cause constant fatigue.

Acute infectious diseases

During any infectious disease, the immune system works in an enhanced mode, and after recovery, protective mechanisms gain energy, requiring rest from the body. As a result of these processes, a person after an illness still feels tired and apathetic for some time. This condition usually resolves on its own two weeks after recovery. But it may not go away – if you had an infection on your legs or your loads were excessive after recovery.
