The causes of facial edema include physiological as well as pathological edema caused by renal edema, angioneurotic edema and thyroid diseases.
1. Physiological facial edema: some patients consume more water before going to bed at night, which leads to water retention in the body, so their faces are swollen when they get up in the morning.
2. Pathologic facial edema:
(1) renal edema: if the patient suffers from kidney disease, it can also cause the phenomenon of facial edema. Because the kidneys are one of the metabolic organs, if the kidneys are diseased, it can affect the metabolic function of the body, which can lead to water retention, resulting in swelling of the face or body.
If it is acute nephritis, it can also be accompanied by urine color of wash water; nephrotic syndrome, it can lead to edema of eyelids, as well as limbs, scrotum and so on.
(2) Angioneurotic edema: it is usually caused by eating certain drugs or food, leading to nerve reaction, and it is more common in the upper lip area, and it usually subsides within two days, but it is easy to recur.
(3) Thyroid disease: such as hypothyroidism, which is a generalized metabolic syndrome caused by hypothyroidism or thyroid hormone resistance. It can also lead to body edema, weight gain, constipation and other uncomfortable symptoms.
Therefore, when the face is swollen, it is necessary to pay attention to the hospital in time, identify the cause of the disease and then carry out targeted treatment.
