Dizziness after strenuous exercise

Introduction Dizziness after strenuous exercise is one of the clinical manifestations of anemia. Anemia refers to the reduction of the total amount of red blood cells in the circulating blood to below normal. However, because the measurement technique of total red blood cells in circulating blood is complicated, it is generally referred to clinically that the concentration of hemoglobin in peripheral blood is lower than the normal standard of the same age group, the same sex and the same region. The normal domestic standards are slightly lower than the foreign standards. In coastal and plain areas, the hemoglobin of adult men is less than 12.5g/dl, and the hemoglobin of adult women is less than 11.0g/dl, which can be considered as anemia. Children under the age of 12 are about 15% lower than the normal value of hemoglobin in adult men, and there is no significant difference between boys and girls. Areas with high altitudes are generally higher.

Cause

Cause: Anemia causes the total amount of red blood cells in the systemic circulation blood to decrease below the normal value. There is not enough blood red blood cells to transport nutrients and oxygen during exercise, resulting in dizziness after exercise. In addition to investigating the causes of anemia, it is also important to understand whether anemia occurs rapidly or slowly. The course of illness is short or slow. Mass, sporadic or individual occurrence. The symptoms of anemia are progressive or effective, providing a strong basis for further diagnosis.

For clinical diagnosis of anemia, the following points must be noted.

1, medical history

In addition to investigating the cause of anemia, it is also important to understand whether anemia occurs rapidly or slowly. The course of illness is short or slow? Mass, sporadic or individual occurrence? Is the symptoms of anemia aggravated or effective? Provide a strong basis for further diagnosis.

2, mucosal color

Mucosal color is sensitive and reliable to reflect the degree of anemia and anemia, and is a window to understanding anemia. When examining the mucosa, it is important to pay attention to the presence or absence of bleeding points, and if necessary, it can be confirmed by the blood vessel fragility test. The mucous membrane is usually examined for the conjunctiva.

3, heart and lung dysfunction

Anemia, due to blood supply and blood oxygen dysfunction, will inevitably cause heart and lung insufficiency, accompanied by symptoms of cardiopulmonary dysfunction, such as heart rate, respiratory increase, breathing difficulties. It is also a testimony to the degree of anemia.

4, the degree of anemia

The degree of anemia is mainly reflected by the degree of reduction of anemia indicators and the therapeutic effect. Both of these aspects are reflected by the comprehensive function of peripheral blood and bone marrow hematopoiesis. In terms of quantitative changes, only the peripheral blood components decreased and the bone marrow hematopoietic effect did not change, the anemia was mild; on the contrary, the peripheral blood components were significantly reduced, the bone marrow hematopoietic function was also reduced, and the anemia was more serious. The same is true for therapeutic effects. After treatment, peripheral blood components, especially reticulocytes, increase, bone marrow hematopoiesis has a proliferative effect, and anemia is mild; on the contrary, although treated, peripheral blood components have rebounded, while bone marrow hematopoiesis still have no proliferative effect. , the degree of anemia is severe, may belong to aplastic anemia.

5, the consistency of anemia indicators

There is almost consistency between the indicators that reflect changes in blood components (quantity differences) and qualitative changes (morphological differences, ratio variations, etc.), such as the number of red blood cells and hemoglobin, peripheral blood red, granulocyte ratio, and bone marrow red, granulocytes. The ratio, as well as the peripheral blood and bone marrow, are consistent and echo each other. If the changes between the corresponding indicators are inconsistent, you should carefully explore the reasons and try to correct them in order to get the correct conclusions.

Differential diagnosis

Tension and dizziness: Tension and dizziness means that when the spirit is tense, it will be dizzy, the more nervous, the more dizzy it is.

Intermittent dizziness: Frequent intermittent dizziness is usually caused by low blood pressure or high blood pressure. Young people are generally caused by hypotension, and cervical spondylosis can also cause dizziness.

Persistent dizziness: general general acute dizziness, which lasts for a maximum of one to two weeks, and remains dizzy if maintained for more than one month. It can be caused by many factors such as brain diseases, anemia, and systemic diseases.
