Diabetic nephropathy is a severe complication of diabetes that affects the kidneys. Almost one in three people with diabetes end up getting diabetic nephropathy.
Chronic kidney disease (CKD) often develops slowly and doesn’t show many signs. A lot of diabetic patients don’t even realise they have Diabetic Nephropathy until it’s reached an advanced stage, and that’s when they might require dialysis (a treatment that cleans the blood) or a kidney transplant to stay alive.
If you have diabetes, you should get your kidneys checked regularly. Your doctor can do this with simple blood and urine tests. Regular check-ups give you the best chance of spotting Diabetic Kidney early if it develops. Treating it early is the most effective way to prevent other health problems.
Symptoms of Diabetic Kidney
- Swelling in the legs, ankles and feet.
- Increased urination
- High blood pressure
- Fatigue
- Poor appetite
- Itching and extremely dry skin
- Nausea and vomiting
As kidney damage gets worse, your kidneys can’t clean your blood properly. This means that waste starts to pile up in your body and can become really harmful, a condition called uremia. People with uremia often feel confused and sometimes even go into a coma.
Causes of Diabetic Kidney
There are millions of tiny filters called nephrons present inside your kidneys. Over time, if you have high blood sugar due to diabetes, it can harm the blood vessels in your kidneys and also affect the nephrons, making them less effective. Additionally, many people with diabetes end up having high blood pressure, which can also cause damage to their kidneys.
Risk Factors
Several factors increase the risk of developing diabetic nephropathy:
1. Duration of Diabetes
The longer an individual has diabetes, the higher their risk of developing kidney complications.
2. Poorly Controlled Blood Sugar
Consistently high blood sugar levels can accelerate kidney damage.
3. High Blood Pressure
Hypertension can exacerbate the impact of diabetes on the kidneys.
4. Genetics
Some individuals may have a genetic predisposition to kidney problems associated with diabetes.
How is Diabetic Nephropathy Diagnosed?
Diabetic nephropathy is typically diagnosed through a series of tests and assessments. Here’s how it is usually done:
Urine Tests: One of the initial steps is to check a person’s urine for the presence of protein. High levels of protein in the urine, known as proteinuria, can indicate kidney damage. A urine sample is collected and analysed.
Blood Pressure Measurement: Monitoring blood pressure is crucial because high blood pressure can be both a cause and a result of diabetic nephropathy. Regular blood pressure checks help in assessing kidney health.
Blood Tests: Blood tests are performed to measure serum creatinine and estimate the glomerular filtration rate (eGFR). Elevated levels of serum creatinine and a reduced eGFR may suggest kidney problems.
Kidney Biopsy: In some cases, a kidney biopsy may be necessary. A tiny sample of kidney tissue is extracted for a closer examination to determine the extent of damage and the specific cause.
Imaging: Imaging studies such as ultrasound or CT scans may be conducted to get a visual representation of the kidneys. These scans can help identify any structural abnormalities.
Medical History and Physical Examination: The doctor will also take a detailed medical history, including any family history of kidney disease and the duration of diabetes. A physical examination may reveal signs of kidney issues.
Regular Monitoring: Since diabetic nephropathy can progress slowly over time, regular check-ups and monitoring are essential, especially for individuals with diabetes.
It’s important to note that early detection and regular monitoring are the keys to managing diabetic nephropathy effectively, as they allow for timely interventions to slow down or prevent further kidney damage.
The Impact of Diabetes on Kidney Function
As diabetic nephropathy advances, it can lead to significant impairment in kidney function. This can result in a range of complications, including:
Fluid Retention: Impaired kidney function can lead to fluid retention, causing swelling in the legs, ankles, and around the eyes.
High Blood Pressure: Kidney damage can further elevate blood pressure, creating a dangerous cycle.
Electrolyte Imbalance: The kidneys regulate electrolyte balance, and dysfunction can disrupt this delicate equilibrium.
Cardiovascular Complications: Kidney problems can increase the risk of heart disease and stroke.
Management and Prevention
Preventing and managing diabetic nephropathy requires a multi-faceted approach. It’s essential for individuals with diabetes to work closely with their healthcare team to:
- Control Blood Sugar: Maintaining stable blood sugar levels through medication, diet, and lifestyle modifications is critical.
- Manage Blood Pressure: Keeping blood pressure within a healthy range can slow the progression of kidney damage.
- Lifestyle Modifications: Adopting a healthy lifestyle with a balanced diet and regular exercise can support overall health.
