A drop in blood pressure after running may be caused by a decrease in blood flow, vasodilatation or heart disease.
1. Decrease in blood volume: After running or strenuous exercise, because of the large amount of sweating will lead to the loss of fluid, the effective circulating blood volume decreases, which causes a drop in blood pressure, so you need to replenish the water as well as the electrolytes in time to maintain the effective circulating blood volume after the exercise.
2. Vasodilatation: blood vessels are in a state of expansion after exercise, which is also an important reason for the drop in blood pressure. Blood pressure has a direct relationship with the effective circulating blood volume and the state of blood vessels, and blood pressure will have a significant drop after vasodilatation.
3. Heart disease: such as exercise induced cardiac infarction, resulting in a drop in blood pressure or exercise induced heart failure, malignant arrhythmia will appear blood pressure drop symptoms.
If your blood pressure drops after you come back from running, and if the symptoms continue to be unrelieved, or if they are accompanied by other symptoms such as chest tightness and chest pain, it is recommended that you consult a doctor in time.
