Patient's question:
NoDoctor's answer:
This situation is mainly considered to be caused by a decrease in blood oxygen levels, such as pneumonia, high-altitude areas, etc. It is recommended that you go to the hospital for a check-up. First, undergo an echocardiogram of the heart, chest X-ray, blood routine tests, etc., to determine the cause before symptomatic treatment. Additionally, cold may also be a cause, so it is also recommended to pay attention to keeping warm.
