Waking up with swollen eyes at bedtime should firstly rule out poor sleep quality at night, and secondly rule out pathological factors such as kidney, liver, heart and thyroid diseases. Waking up from sleep with swollen eyes is relatively common in life, and in most cases it is caused by physiological factors, such as poor sleep at night, especially staying up late, and swollen eyes are very common the next day, and this situation basically improves after a good rest. However, if the patient is not affected by the above physiological factors, or if the above symptoms occur repeatedly, pathological factors should be excluded, such as nephritis, nephrotic syndrome, liver cirrhosis, right heart failure and hypothyroidism, etc. These diseases can cause not only eye swelling, but also edema in other parts of the body, such as bilateral lower limb edema, foot edema, etc., and are accompanied by symptoms For example, kidney diseases are usually accompanied by increased blood pressure and increased foam in the urine, cirrhosis of the liver usually has a long history of liver disease, right heart failure is usually accompanied by shortness of breath after activity, hypothyroidism is usually accompanied by symptoms of fear of cold, etc. To confirm the diagnosis, we must also rely on the corresponding auxiliary tests.
