Diabetic nephropathy is damage to small blood vessels caused by diabetes, and the kidneys contain a large number of small blood vessels. Therefore, it generally takes more than ten years for diabetes to damage these small blood vessels, causing kidney lesions, proteinuria, renal failure, and other clinical manifestations. This disease can be treated in departments specializing in diabetes or endocrinology, as well as in nephrology. In the early stages of diabetic nephropathy, treatment primarily involves controlling blood sugar levels, and visiting departments like diabetes or endocrinology might be more specialized in this regard. These departments are proficient in adjusting medications for blood sugar control. When patients develop significant proteinuria, the condition progresses, and it is advisable to visit nephrology. At this point, the treatment focuses on the kidney lesions, as well as managing complications caused by diabetic nephropathy.

Can diabetic nephropathy with swollen feet be treated?

Diabetic nephropathy in the middle and later stages can cause edema, especially in patients with significant proteinuria or renal failure. Many patients can even experience generalized edema. For such patients, swollen feet and swelling in other parts of the body can be considered for appropriate use of diuretics to increase urine output and eliminate edema. However, generally, the extensive use of diuretics is not actively advocated because excessive diuresis can also lead to significant protein loss and even cause insufficient blood volume, affecting the blood supply to the kidneys. Nevertheless, some patients with severe conditions that cause pulmonary edema and heart failure may not respond well to diuretics. In such cases, dialysis ultrafiltration may be required to remove water, alleviate edema, and reduce cardiac stress.

How to reduce proteinuria in diabetic nephropathy.

A major clinical feature of diabetic nephropathy is the occurrence of proteinuria, which, if the condition continues to progress, can lead to kidney failure. Controlling proteinuria in the early stages of the disease is indeed very important. In terms of treatment, it is primarily necessary to use medications or insulin to control the patient's blood sugar, as hyperglycemia is the fundamental cause of diabetic nephropathy. Additionally, these patients often also have hypertension, necessitating the use of antihypertensive drugs to control blood pressure. When the patient's kidney function is not severely impaired, ACE inhibitors or ARBs can be the preferred choice of antihypertensive drugs, as they not only control blood pressure but also reduce proteinuria. However, if the patient's serum creatinine is significantly elevated, such as over 264 µmol/L, these drugs should no longer be used. (Medications should be used under the guidance of a doctor.)

Early signs of diabetic nephropathy

Diabetic nephropathy is caused by long-term diabetes leading to damage in the small blood vessels. Generally, patients have a history of diabetes for over ten years. Diabetic nephropathy progresses through several stages. In the early stages, patients primarily exhibit microalbuminuria. Due to the presence of protein in the urine, patients may experience increased urine foam, especially noticeable with morning urination. Some patients may develop swelling in the lower limbs and around the eyelids. As the condition progresses, the amount of urine protein increases and the swelling becomes more pronounced, potentially reaching the level of nephrotic syndrome.

Symptoms of stage four diabetic nephropathy

Stage four of diabetic nephropathy indicates the presence of significant amounts of urinary protein. At this stage, patients may exhibit symptoms of nephrotic syndrome, which means the total urinary protein quantification over 24 hours may exceed 3.5 grams, and the plasma albumin level may be lower than 30 grams per liter. Due to the large amount of protein leakage, patients may experience edema, presenting as swelling of the lower limbs or eyelids, or even severe generalized swelling. In addition to edema, patients may also have pleural and abdominal effusion, leading to pulmonary edema. Excessive fluid can overburden the heart, causing heart failure, which manifests as chest tightness, shortness of breath, and difficulty breathing, especially when the patient is active, these symptoms of chest tightness and shortness of breath become more pronounced.

Is diabetic nephropathy stage 3 reversible?

Patients with diabetic nephropathy actually have an irreversible condition. If a patient has developed mild to moderate proteinuria and entered stage three, it's generally because of long-term high blood sugar, oxidative stress, and an excess of glycation end products damaging the capillaries of the glomerulus, resulting in increased permeability and the occurrence of proteinuria. The damage that has already occurred cannot be reversed; however, patients still need active treatment to control their blood sugar and blood pressure in order to slow down the progression of diabetic nephropathy as much as possible. Stage three diabetic nephropathy is incurable, but treatment can slow the progression of the kidney disease, preventing the development from microalbuminuria to macroalbuminuria. Stage three refers to the early period of diabetic nephropathy, typically seen in diabetic patients who have had the disease for more than five years. It can feature a continuous increase in urinary albumin excretion rates. High filtration rates and long-term poor metabolic control may be reasons for the persistent microalbuminuria. During this stage, patients may experience a mild increase in blood pressure, and reducing blood pressure can decrease the excretion of microalbumin. During this period, strict control of blood sugar is necessary. Oral hypoglycemic drugs can be used for treatment, and it's crucial to regularly monitor fasting blood glucose, postprandial blood glucose, and glycated hemoglobin. Blood pressure should also be actively controlled, generally targeting a value of 130/80mmHg. Angiotensin-converting enzyme inhibitors and angiotensin II receptor antagonists are preferred as they can lower blood pressure, reduce proteinuria, and have a protective effect on the kidneys, thus delaying the progression of kidney disease.
