What Is Diabetic Kidney Disease?

The Stages of Diabetic Kidney Disease

Signs and Symptoms of Diabetic Kidney Disease
- Nausea and vomiting
- Loss of appetite
- Trouble sleeping
- Signs of fluid buildup, such as shortness of breath from fluid in the lungs or swelling in the feet
- Feeling weak and fatigued
- Abnormal urine output, including very small amounts of urine
- Itchiness
- Fatigue
- Swelling in the feet
- Foamy urine
- Symptoms related to diabetes, such as delayed wound healing and numbness or tingling
- Nephrotic syndrome, excess protein in the urine that leads to other symptoms like fluid buildup (edema)
Causes and Risk Factors of Diabetic Kidney Disease
The main job of the kidneys is to filter the body’s accumulated waste products as well as salt and minerals your body needs — sodium, calcium, potassium, phosphorus — into tiny tubules where they are either reabsorbed into the blood or passed into urine.
- Obesity
- A family history of chronic kidney disease
- High blood pressure
- Heart disease
- Increased age
- Duration of diabetes
- Being a man or a postmenopausal woman
- Dyslipidemia (abnormal lipid levels)
- Smoking
- Sedentary lifestyle
- A diet high in animal protein
- High salt intake
How Is Diabetic Kidney Disease Diagnosed?
Doctors use a few different tests to determine whether someone has chronic kidney disease:
- Measurement of Urine Albumin-to-Creatinine Ratio This urine test assesses how much albumin protein is present in the urine, an indication of kidney dysfunction.
- Measurement of the Estimated Glomerular Filtration Rate (eGFR) This measurement of kidney function uses data from a person’s bloodwork to estimate how well the kidneys are filtering blood.
- Kidney Imaging Ultrasounds and computerized tomography can help identify kidney changes and problems.
To determine whether diabetes is the cause of chronic kidney disease, healthcare providers can perform a kidney biopsy, although this procedure isn’t as common as other diagnostic tests.
Treatment and Medication Options for Diabetic Kidney Disease
Medication Options
Several medications can help manage kidney disease. Some may help slow or halt the progression of kidney disease, while others address additional issues like blood pressure or diabetes.
- ACE Inhibitors These medications help decrease protein in the urine and can slow declines in kidney function as well as reduce blood pressure.
- Angiotensin Receptor Blockers ARBs also help reduce protein in the urine, slow declines in kidney function, and decrease blood pressure.
- Diuretics These medications allow more fluid to leave the body via urine.
- GLP-1 Receptor Agonists By supporting weight loss and blood sugar management, these medications can reduce risk of kidney disease, slow its progression, and improve outcomes in those with kidney dysfunction.
- Mineralocorticoid Receptor Antagonists These medications help the kidneys remove excess water and salt via urine without depleting potassium levels, lowering blood pressure as a result.
- SGLT-2 Inhibitors These medications can help decrease blood sugar by allowing more sugar to leave the body via urine when someone’s kidney function is normal. When kidney function is reduced, SGLT-2 inhibitors can help decrease risk of further kidney disease progression.
Dialysis
Dialysis is usually recommended when around 90 percent of kidney function is lost. There are two types of dialysis: hemodialysis and peritoneal dialysis.
- Hemodialysis This involves going to a dialysis center three times a week for several hours, where your blood is pumped through a machine that filters out waste products and excess fluids and then returned to your body. Sometimes hemodialysis can be done at home, but such treatment may need to occur more frequently and can take longer to complete.
- Peritoneal Dialysis This is a self-administered procedure performed at home and involves putting a dialysis solution in your abdomen through a catheter placed surgically near your navel. The solution remains in your abdomen for several hours before being drained and replaced with fresh dialysis solution. This process can be done manually throughout the day or by machine at night.
Kidney Transplant
A kidney transplant may help improve life expectancy and is often a better option than dialysis. A person with kidney disease might receive dialysis while waiting for a kidney transplant.
Not everyone is eligible for a kidney transplant, such as people who have had cancer recently, people with severe obesity, or those who haven’t adhered to recommended dialysis or medication treatments.
Prevention of Diabetic Kidney Disease
Lifestyle Changes for Diabetic Kidney Disease
Many of the healthy habits that can help you manage diabetes, such as eating a balanced diet and exercising regularly, can also help keep your kidneys healthy and slow the progression of chronic kidney disease.
Eat a Healthy Diet
If you have diabetic kidney disease, you may be asked to eat a specialized diet, which could include:
- Limiting salt and sodium consumption
- Limiting potassium or phosphorous intake
- Detailed protein goals and limits
Watch Your Protein and Salt Intake
Limiting salt in your diet can help decrease blood pressure and reduce fluid buildup. To limit salt:
- Season foods with sodium-free herbs and spices.
- Avoid packaged food, fast food, and salty snacks.
- Check all food labels for sodium content.
A protein-heavy diet may make your kidneys work harder. Talk to your doctor about how much protein you should eat, and opt for lean sources like fish or chicken.
Get Regular Exercise
Exercise can help you manage your weight, improve your mental health, and achieve your blood sugar and blood pressure goals.
For people with diabetes or diabetic kidney disease, lower-intensity exercise may be best. Consult your healthcare provider prior to exercising to create a fitness plan that is safe for your condition and tailored to your specific goals.
Address Your Sleep and Stress Issues
Diabetic Kidney Disease Prognosis
Continue working with your healthcare provider to explore care options relevant to your situation to best manage your chronic kidney disease.
Complications of Diabetic Kidney Disease
Chronic kidney disease doesn’t just affect the kidneys. It can also lead to a number of complications that may require specialized treatment, such as:
- Abnormalities in salt and fluid balance
- Anemia
- Bone and mineral disorder
- Cardiovascular disease
- High blood pressure
- High phosphorus levels
- High potassium levels
Research and Statistics: How Many People Have Diabetic Kidney Disease?
However, not everyone with chronic kidney disease has diabetes.
Disparities and Inequities in Diabetic Kidney Disease
While diabetic kidney disease can affect anyone, some people are more likely to develop the condition or struggle to receive appropriate diagnosis and treatment.
Support for Diabetic Kidney Disease
This nonprofit assists people with kidney disease nationwide, helping connect them with others who are going through similar health experiences. It provides resources like virtual support groups, a peer support hotline, a blog, and a podcast all focused on providing support to people with chronic kidney disease.
American Association of Kidney Patients
Founded in 1969, AAKP serves as an advocate for people with kidney disease to help improve patients’ treatment. It provides educational resources and seeks to foster community among people with kidney disease by connecting them with renal support groups in five states as well as virtual support group options.
This group raises awareness of kidney disease and helps fund advancements in kidney disease research and treatment. It hosts a number of events in several states annually and provides a number of community resources, such as NKF Peers, which connects those affected by kidney disease with a mentor.
Common Questions & Answers
Chronic kidney disease cannot be reversed. However, treatments can help to slow or halt the progression. In severe situations, you need to use dialysis or receive a kidney transplant.
About half the people with type 2 diabetes and one-third of those with type 1 diabetes develop diabetic kidney disease. However, risk factors vary from person to person, and some of your lifestyle choices can help reduce your risk.
People with diabetes and kidney disease can protect their remaining kidney function by avoiding foods that are high in sodium, potassium, phosphorus, and sugar. Limiting your consumption of processed foods and alcohol can be helpful as well.
The Takeaway
- Diabetic kidney disease is chronic kidney disease that occurs as a complication of diabetes.
- Early stages of diabetic kidney disease are often asymptomatic, but more advanced stages are typically marked by nausea, vomiting, fluid buildup, fatigue, and abnormal urine output.
- While there isn’t a cure for diabetic kidney disease, blood glucose management, medications, and lifestyle modifications can all play a significant role in managing the condition and maintaining quality of life.
- Early intervention is the best way to slow or halt the progression of diabetic kidney disease, so annual screenings for people with diabetes are critical.
