Facial edema in the elderly can be caused by physiologic and pathologic factors (e.g., nephritis and coronary artery disease). Usually, general treatment and medication can be used. 1. Physiological factors: As a result of drinking more water, especially at night, water discharge is slower than during the day, leading to the accumulation of water in the body, resulting in facial edema in the elderly. Can reduce the amount of water at night, as well as exercise to improve the way, in doing exercise will be a lot of sweat, so as to achieve the effect of facial swelling. 2. Pathological factors (1) nephritis: nephritis will lead to a decrease in the glomerular filtration rate, resulting in a slight hypoproteinemia, which will cause the water in the patient’s blood vessels to the outside of the blood vessels, and the outside of the blood vessels will lead to facial edema in the elderly. It can be treated with hydrochlorothiazide as prescribed by the doctor, which can play a diuretic role by excreting excessive water and sodium in the body. It can reduce the volume of extracellular fluid, reduce edema, thus alleviating the situation of facial edema in the elderly. (2) Coronary heart disease: Long-term coronary heart disease in the elderly will lead to an increase in the load on the patient’s heart, which will cause the heart’s function to deteriorate, and then cause the metabolism of water and fluid malfunction, resulting in facial edema in the elderly. You can follow the doctor’s instructions to use isosorbide nitrate with furosemide treatment to reduce the heart load, as well as diuretic to reduce the role of edema, so as to alleviate the situation of facial edema in the elderly. If the elderly facial edema, it is recommended to consult a doctor to identify the cause of the disease and then targeted treatment.
