Diabetic nephropathy generally does not cause painful symptoms.

Diabetic nephropathy refers to the kidney damage that results from long-term diabetes, caused by factors such as hyperglycemia, oxidative stress, and an increase in advanced glycation end products.

In the early stages, patients may experience an increase in kidney size and an increased glomerular filtration rate. As the condition progresses, proteinuria may occur, and it could eventually lead to severe renal failure. Throughout this process, patients typically do not experience pain because the kidneys do not have nerve innervation and therefore do not feel pain. Thus, including diabetic nephropathy, various kidney diseases and nephritis generally do not manifest with pain.

Is diabetic nephropathy with facial swelling serious?

Patients with diabetic nephropathy who experience facial swelling should not use this symptom as a basis for judging the severity of their condition. Diabetic nephropathy is divided into five stages. The condition is relatively mild during the first three stages. By the fourth stage, patients begin to exhibit significant proteinuria, and by the fifth stage, they experience severe renal failure. Conditions in these last two stages are quite severe. However, patients might also experience facial swelling during the first three stages, and while the likelihood of facial swelling increases during the fourth and fifth stages, some patients in these stages might not show obvious edema. Therefore, it is difficult to determine the severity of the condition based solely on swelling. Patients need to undergo 24-hour urinary protein quantification and blood tests to assess kidney function in order to judge the severity of their condition.

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.

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.

Is stage three diabetic nephropathy severe?

Stage three of diabetic nephropathy refers to patients who have persistent microalbuminuria, indicating a relatively mild state of the disease at this time. In fact, diabetic nephropathy is divided into five stages. During the first and second stages, patients generally do not exhibit specific symptoms clinically and may even test negative for proteinuria; however, an increase in kidney size and glomerular filtration rate may occur. By the third stage, patients begin to exhibit small or micro amounts of urinary albumin. The pathological damage to the kidneys at this stage is not considered particularly severe. Patients may experience hyalinization of small arteries and nodular lesions in the glomeruli. Within the staging of diabetic nephropathy, this does not constitute a particularly severe phase; however, the condition of the patients may continue to progress, leading to significant proteinuria and even renal failure.

Is early diabetic nephropathy reversible?

Diabetic nephropathy clinically mainly manifests as an increase in urine protein on routine urine tests. Thus, diabetic nephropathy can be classified into different stages. In the early stages, microalbuminuria appears, and at this early phase, diabetic nephropathy is actually reversible. However, if the condition progresses with significant proteinuria, it becomes difficult to reverse diabetic nephropathy through intervention treatments. Most clinical patients may experience a slight reduction in urine protein or maintain this condition long-term without further progression. However, some patients have already experienced an increase in creatinine levels by the time they reach this stage of diabetic nephropathy, making it particularly challenging to reverse the condition once creatinine levels rise. Therefore, for diabetic nephropathy, early detection and treatment are crucial, with the most important goal being the prevention of the disease's onset.
