There are many reasons for dorsal edema, such as physiological phenomenon, nephrogenic edema, cardiogenic edema, hepatic edema and so on.
1. Physiological phenomenon: if the patient sits for a long time or ingests too much sodium, edema of the instep may occur, which can be gradually relieved after sufficient rest and dietary adjustment.
2. Nephrogenic edema: Kidney diseases usually show water and sodium retention, so nephrogenic edema not only occurs in dorsal edema, but also can be accompanied by proteinuria, hematuria, eyelid swelling and other phenomena.
3. Cardiogenic edema: cardiac insufficiency, heart failure and other diseases will lead to the reduction of cardiac blood volume, so the phenomenon of dorsal edema will occur.
4. Hepatogenic edema: abnormalities in liver function can cause a decrease in protein synthesis in the body, which can lead to dorsal edema after the appearance of hypoproteinemia.
There are many reasons for dorsal edema, if we exclude the physiological phenomenon, it is recommended that patients go to the hospital in time to improve the examination, under the guidance of a professional doctor to take standardized treatment, do not ignore the symptoms, take it lightly.
