See below. Blood sugar control is extremely important it is important to maintain a Albumin level in the normal range and I generally do not recommend severe protein restriction for that reason. Have a moderate restriction only if Albumin levels are normal maintain LDL cholesterol less than 70 if you have leg swelling or high blood pressure you will need to restrict salt and fluid intake as well.
Low protein. It is recommended by the american diabetes association for people with kidney insufficiency to be on a lower protein diet. Limiting consumption of protein intake to 0.8–1.0 grams per kilogram of body weight per day in individuals with diabetes and the earlier stages of chronic kidney disease (ckd) and to 0.8 grams per kilogram of body weight per day in the later stages of ckd.
Control diabetes. This takes first priority. So the diet is a strict diabetes diet. Also, if not in an early stage in the nephropathy, protein restriction would be helpful.
Avoid sweets. And reduce protein intake see nutritionist in order to 'do it right' and be able to comply.
No. There are other types of nephropathy, but diabetes is the cause of diabetic nephropathy.
Protein in urine. If you have diabetes, early diabetic nephropathy can be suspected if your doctor tests the urine for microalbumin, and then later for protein. Usually no need to do a kidney biopsy especially if the retina of the eye also has diabetic changes. Your nephrologists determines this.
Urine tests. For micro and macro amounts of Albumin in urine and blood tests of kidney function.
Protein loss. High blood sugars and high blood pressure influence how the kidney clears waste products from our body. An early sign of impaired clearing is seeing if any small proteins that are usually kept in the blood stream in turn "leak" from the kidney into the urine- this test is called urine microalbumin and should be done annually for all diabetics.
See below. Diabetic nephropathy as the name suggests is a "disease" of the kidney in diabetics with appearance of protein in the urine and slow deterioration of kidney function. Not all patients with diabetes get nephropathy. Seek advice from a nephrologist a kidney biopsy is not always necessary but the microscopic appearance is very typical.
Urine tests. Urinalysis, urine Albumin to creatinine ratio, blood biochemistry, serum creatinine with GFR estimation, kidney ultrasound. Tests to consider- 24 hour urine collection, ct abdomen, magnetic resonance angiography, doppler ultrasound and kidney biopsy.
Hurt kidneys. High sugars as well as high blood pressure can damage your kidneys over time. Our kidneys filter and process things. When they're hurt, they don't filter as well, and can leak protein into your urine. We check how well your kidneys are working by  blood test  urine test for microalbumin. Not everyone with diabetes gets kidney problems. Good luck.
Edema. Diabetic nephropathy causes glomerular damage and leakage of proteins in the urine. If left untreated it may progress to generalized edema, and renal failure with symptoms of weakness, anemia, high blood pressure and heart disease.
Diabetic nephropathy. Unfortunately diabetic nephropathy is usually asymptomatic until the kidney disease so very advanced. The things kidney doctors look for is protein in the urine and the degree of kidney function. If the amount of protein that is in the urine can be decreased, this has a positive effect on the health of the kidneys.
Usually none. This term generally refers to excessive amount of protein leaking out into the urine. It is detected by urine tests, in combination with blood testing. In severe cases, in part, you may have edema (swelling).
It is... a progressive damaging effects to capillaries in/near glomeruli leading to local inflammatory change and scarring with subsequent malfunction in filtering the blood for reabsorbing useful blood components and excreting the unwanted metabolic wastes, which exact causes are still unclear, though, long-term high blood sugar is the culprit. This is usually a slow process of >5-15 years.
