Dizziness after jogging may be related to transient cerebral blood supply insufficiency, and may also be caused by cardiopulmonary diseases and elevated blood pressure fluctuations. 1. transient cerebral blood supply insufficiency: the body consumes more oxygen when running, coupled with a relatively fast respiratory rate, which can easily cause excessive ventilation, resulting in transient blood supply insufficiency in the brain, which may cause dizziness after jogging. 2. Cardiopulmonary diseases: If you suffer from hypertrophic obstructive cardiomyopathy, heart failure, certain arrhythmias, chronic obstructive pulmonary disease, bronchiectasis and other diseases, the cardiopulmonary function itself is relatively insufficient, dizziness, black haze, respiratory distress and other symptoms after exercise, and in severe cases, there will also be impaired consciousness. 3. elevated blood pressure fluctuations: especially people with a history of high blood pressure, after jogging, it is likely to cause blood pressure fluctuations, resulting in increased pressure in the cerebral blood vessels, may cause dizziness, may also be accompanied by headache, nausea and other symptoms. Dizziness after jogging, may also be caused by other reasons, should pay attention to reasonable rest, if the symptoms continue to be unable to alleviate, should seek medical attention as soon as possible, after diagnosis of triggers, give targeted treatment.
