Why Diabetic Nephropathy Patients Have Edema in Lower Limbs?

Why do diabetic nephropathy patients have edema in lower limbs? As we know, one important function of kidney is to filter blood, thus discharging excessive water and keep water balance in the body. However, in diabetic nephropathy, damage in the kidney also takes place, which influences the filtrating ability of the kidney, thus causing edema. Edema can also be called edema, dropsy or swelling, which usually firstly appears in eyelids, ankles and lower limbs.
How does edema come into being for diabetic kidney disease patients?
On one hand, the renal glomerular filtrate rate decreases, but the absorption of water and sodium in renal tubules is normal, which leads to the retention of water and sodium, thus causing the increased permeability of the capillaries in the whole body. In this case, water retention appears in the tissue space. The above condition is usually seen in glomerular nephritis.
On the other hand, with the development of diabetic kidney disease, a large amount of proteinuria appears, in which protein is lost, which leads to low protein in plasma. The osmotic pressure in plasma declines, so liquid flows and edema comes into being. In this case, lower limbs edema will also appear accordingly.
How to deal with or treat edema or dropsy or swelling caused by diabetic nephropathy? In our Hospital, we have researched immunotherapy, which is on the basis of the pathological mechanism of diabetes and kidney disease. Immunotherapy is a combination of both Chinese herbs and western medicine, which can be divided into 6 steps including immune diagnosis, immune clearance, immune blocking, immune tolerance, immune adjustment and immune protection. After these, we believe that edema in lower limbs for diabetic nephropathy can also disappear accordingly.
