68-year-old Mr. Li, a mahjong enthusiast, was puzzled when he was diagnosed with pulmonary embolism. He frequently played mahjong for long hours without moving, which led to blood stasis and the formation of blood clots in his lungs.
Research suggests that people with non-O blood types, particularly AB blood type, are at a higher risk of developing blood clots. Symptoms of blood clots include numbness in the limbs, swelling, intermittent claudication, and redness in the hands and feet. To prevent blood clots, it is important to maintain a healthy diet, avoid prolonged sitting, and perform ankle pumping exercises.
