Emphysema with facial swelling in the elderly may be caused by right heart failure due to chronic pulmonary heart disease or by the presence of kidney-related diseases. 1. If an elderly person has a history of emphysema with swollen face, right heart failure due to chronic pulmonary heart disease is the first consideration. Long-term emphysema can cause pulmonary heart disease, which affects the blood circulation of the heart, leading to right heart failure, resulting in impaired blood return and swelling of the face. 2. If the elderly themselves have kidney-related diseases, including various types of nephritis, etc., which can affect the circulation of fluid throughout the body, resulting in nephrogenic facial swelling, is also a common cause. Therefore, it is recommended to consult a doctor for examination and treatment under the doctor’s guidance, subject to the doctor’s opinion.
