Such symptoms as weakness, nausea, dizziness are signs of many serious diseases. Moreover, such a condition can be caused both by infectious diseases and by disruptions in the functioning of certain body systems.
Here are some diseases characterized by the occurrence of the above symptoms.
Acute gastroenteritis
The causative agent of the disease is an intestinal infection. As a rule, the disease begins acutely. Against the background of sharp pains in the abdomen, weakness, nausea, dizziness appear. Then comes diarrhea. In some cases, a slight increase in temperature may occur.
Hypoglycemia
People with this pathology experience a sharp decrease in blood sugar levels. As a result, the body begins to produce large amounts of adrenaline - a hormone that increases blood pressure and speeds up the pulse. At the same time, the patient does not leave a feeling of anxiety, panic. Then symptoms such as weakness, nausea, dizziness, fatigue,confusion, poor motor coordination, blurred vision. In some cases, fainting and convulsions are possible.

The causes of vegetovascular dystonia are most often hormonal changes in the body. However, the disease often occurs with neurosis, stress, and also as a result of organic damage to the brain (tumors, injuries, strokes).
