Symptoms such as weakness, nausea, dizziness are signs of many serious diseases. Moreover, such a condition can be caused by both infectious ailments and disturbances 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 diarrhea occurs. In some cases, a slight increase in temperature is possible.
Hypoglycemia
People with this pathology have a sharp decrease in blood sugar levels. As a result of this, the body begins to produce adrenaline in large quantities - a hormone that raises blood pressure and increases the pulse rate. In this case, the patient does not leave a feeling of anxiety, panic. Then symptoms such as weakness, nausea, dizziness, fatigue, confusion, poor motor coordination, blurred vision appear. In some cases, fainting and cramping are possible.
Vegetative dystonia
The disease is caused by changes in the functioning of the autonomic nervous system.
There are characteristic symptoms:
pain in the region of the heart, tachycardia, nausea, dizziness, weakness, temperature (from 35 to 38 degrees), rapid breathing, “stuffy” in the chest, feeling of
lack of air, attacks of shortness of breath, pressure fluctuations, sleep disturbance, fatigue. The causes of vegetovascular dystonia are most often hormonal changes in the body. However, often the disease occurs with neurosis, stress, and also as a result of organic damage to the brain (tumors, injuries, strokes).
Acute gastritis
This disease means inflammation of the gastric mucosa, resulting in damage to the epithelium. The disease is characterized by the following symptoms: a feeling of heaviness, especially in the epigastric region, weakness, nausea, dizziness, and diarrhea. The mucous membranes and skin are pale, the tongue is covered with a grayish coating, the mouth is dry or, conversely, severe salivation. When feeling the abdomen, soreness of the stomach area is detected.
Flu intoxication
Nausea, dizziness, weakness, chills very often occur with various types of SARS. Symptoms of this kind, accompanied by pain in the temples and eyes, nasal congestion, coughing and fever, are clear signs of intoxication. They indicate that a virus that produces biological poison has entered the bloodstream. Treatment should be aimed at removing toxins from the body.
Traumatic brain damage
Loss of consciousness, headache, nausea, weakness, vomiting are the first symptoms resulting from concussions and bruises of the head. In the latter case, fever, impaired speech, and sensitivity are often observed. Similar signs may also indicate high intracranial pressure.
