What reason is lung cancer foot swollen

First: long term malnutrition causes swelling of the feet. Patients with advanced lung cancer are as thin as wood and haggard in shape. This is because the gastrointestinal peristalsis slow down, poor digestion and absorption capacity, resulting in all aspects of the body nutrition can not be replenished in time. This kind of long-term malnutrition leads to the decrease of plasma concentration, the concentration of tissue fluid is higher than that of plasma, and the water in the body will enter the high concentration of tissue from the low concentration of plasma, and eventually cause foot swelling.

Second: low plasma protein causes foot swelling. Due to the long-term malnutrition, lung cancer cells transfer to the digestive tract, the body fever of patients with advanced lung cancer, liver and kidney diseases and other diseases, resulting in the decrease of protein in the body, the decrease of plasma concentration, water into the tissue fluid, eventually leading to the phenomenon of swollen feet in patients with advanced lung cancer.

Third: the heart dysfunction causes the foot swelling. Advanced lung cancer cells may metastasize to the heart, leading to cardiac dysfunction, right ventricular dysfunction, exudative or stenotic pericarditis and other diseases. At this time, the venous pressure of systemic circulation and capillary filtration pressure begin to increase and cause foot swelling. This kind of foot swelling caused by cardiac dysfunction is also called cardiogenic edema.
