Swollen eyes and swollen feet may be caused by heart disease, because heart disease can lead to restricted heart function, which can affect blood circulation and blood return throughout the body, resulting in blood pooling at the ends of the limbs, such as the eyelids and the ends of the hands and feet, resulting in swelling of the feet and eyes. It may also be caused by kidney disease, because kidney disease can also cause patients to have impaired kidney function, which can also lead to abnormal kidney function, and less urine can also lead to the accumulation of water in the body, thus causing local swelling. At this time, it is recommended that patients go to the hospital for relevant examinations in a timely manner, and actively carry out symptomatic treatment after clear diagnosis, so as to effectively improve the situation of swelling, and also to avoid the further development of the disease in the later stages, which can even affect the lives of patients.
