The cause of the edema should be identified. If you drink more water or sleep poorly the night before, it may cause facial edema on the second day. If this is the cause, the symptoms may disappear if the water intake is reduced in the last two days or if the nighttime sleep is improved. If excessive water intake has been ruled out, liver and kidney function abnormalities and cardiac function abnormalities should be considered, and liver and kidney function should be checked and cardiac ultrasound should be done at a regular hospital to clarify whether there are any cardiac function abnormalities. The edema caused by different diseases is different. The edema caused by drinking too much water is mainly in the face, so alternating hot and cold compresses can be applied to the face while reducing the amount of water drunk, which can help reduce the swelling quickly. If the edema is caused by kidney function, the edema is mainly in the face. If the edema is severe, diuretics can be used to reduce the swelling first, and then the kidney disease can be treated. Abnormal liver and heart function edema mainly appears in the lower extremities. You should check liver function for abnormalities and do cardiac ultrasound and test blood BNP for heart failure. If necessary, the edema can be treated with diuretics to reduce the swelling first, and then treated for the cause. If renal disease is present, the treatment plan should be clarified according to the type of renal disease. If heart failure is present, comprehensive symptomatic treatment such as cardiac strengthening, diuretic and vasodilator should be taken.
