Over time, diabetes can damage the small blood vessels in the kidneys, reducing their ability to filter waste and excess fluid from the blood.
This condition is known as diabetic kidney disease.
Following evidence-based diabetic kidney disease management guidelines can help people manage their condition and reduce the risk of complications.
Care may include blood glucose management, blood pressure control, kidney-protective medications when appropriate, individualized nutrition, and regular medical monitoring.
One important challenge is that kidney disease often develops without noticeable symptoms in its early stages.
Regular blood and urine tests can help detect changes before symptoms appear, allowing healthcare professionals to assess kidney function and recommend appropriate treatment.
Although diabetic kidney disease may progress over time, early detection and appropriate medical care can make a meaningful difference.
The goal is not to promise a cure, but to manage risk factors, preserve kidney function where possible, and support long-term health.
This guide explains the key principles of diabetic kidney disease management, including medical treatment, dietary considerations, prevention strategies, and emotional well-being.
It is intended to help readers understand their options and prepare for informed conversations with their healthcare team.

How Diabetic Kidney Disease Management Guidelines Shape Daily Treatment
Managing diabetes and kidney disease often requires a coordinated approach.
Treatment aims to control blood glucose, manage blood pressure, reduce cardiovascular risk, and slow the progression of kidney damage when possible.
The right plan depends on kidney function, urine albumin levels, other medical conditions, and the medications a person can safely take.
1. Managing Blood Glucose and Blood Pressure
Keeping blood glucose within an individualized target range helps reduce the risk of diabetes-related complications.
Blood pressure management is equally important because high blood pressure can place additional stress on the kidneys and contribute to further damage.
Healthcare professionals may recommend lifestyle changes and medications to help manage both conditions.
Blood pressure targets should be individualized, especially for people who have advanced kidney disease, cardiovascular disease, or an increased risk of dizziness and falls.
2. Understanding Kidney-Protective Medications
Several medication classes can help protect kidney and cardiovascular health in appropriate patients with diabetic kidney disease.
ACE inhibitors and ARBs
Angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) lower blood pressure and reduce pressure within the kidney’s filtering system.
They are particularly important for people with diabetes who have hypertension and elevated urine albumin levels.
These medicines are not automatically necessary for every person with diabetes.
Healthcare professionals consider blood pressure, kidney function, urine albumin levels, and other clinical factors when deciding whether to prescribe them.
SGLT2 inhibitors
Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a class of medication that lowers blood glucose by increasing glucose excretion through urine.
Certain medicines in this class also provide kidney and cardiovascular benefits for eligible people with type 2 diabetes and chronic kidney disease.
Their suitability depends on factors such as estimated glomerular filtration rate (eGFR), other medical conditions, and individual safety considerations.
They are not a replacement for insulin when insulin is medically necessary.
Nonsteroidal mineralocorticoid receptor antagonists
Finerenone is a nonsteroidal mineralocorticoid receptor antagonist that may help reduce kidney disease progression and cardiovascular events in selected people with type 2 diabetes and chronic kidney disease.
It may be considered when specific clinical criteria are met, often alongside an ACE inhibitor or ARB.
Because these medicines can increase blood potassium levels, appropriate laboratory monitoring is important.
Some people may also benefit from a glucagon-like peptide-1 receptor agonist (GLP-1 RA), particularly when additional blood glucose, cardiovascular, or kidney risk management is needed.
For detailed recommendations, see the American Diabetes Association’s Standards of Care in Diabetes—2026, Section 11: Chronic Kidney Disease and Risk Management.
3. Monitoring Kidney Function and Urine Albumin
Kidney disease can develop without obvious symptoms, making regular testing an important part of diabetes care.
Two commonly used tests are:
- Estimated glomerular filtration rate (eGFR): Calculated from a blood test, usually serum creatinine, to estimate how effectively the kidneys filter waste.
- Urine albumin-to-creatinine ratio (UACR): Measures the amount of albumin, a protein, in urine relative to creatinine. Elevated levels can indicate kidney damage.
For many people with type 2 diabetes, kidney screening should begin at diagnosis. For people with type 1 diabetes, screening generally begins after five years of living with the condition.
Testing is usually performed at least annually, with more frequent monitoring when kidney disease is established or the results indicate a higher risk.
Abnormal results may need to be repeated or interpreted alongside other clinical findings before a diagnosis or treatment decision is made.
Learn more from the NIDDK guide to chronic kidney disease testing and diagnosis.
4. Turning Medical Recommendations Into Daily Habits
Following diabetic kidney disease management guidelines does not mean trying to change everything at once.
Small, consistent habits can support a broader treatment plan.
Practical steps include taking prescribed medication as directed, attending scheduled appointments, following an individualized eating plan, monitoring blood pressure or blood glucose when advised, avoiding tobacco, and maintaining physical activity appropriate for your health.
It is also important to tell your healthcare team about over-the-counter pain medicines, supplements, and herbal products you use.
Some products may affect kidney function, blood pressure, blood glucose, or medication safety.
The goal is to combine appropriate medical treatment with sustainable daily routines. Regular communication with your healthcare team can help ensure that your plan remains suitable as your kidney function and health needs change.
Understanding Dietary Changes in Diabetic Kidney Disease Management Guidelines
Food plays an important role in managing both diabetes and chronic kidney disease (CKD).
The right eating plan can help manage blood glucose, support healthy blood pressure, and maintain a better balance of minerals in the body.
However, there is no single kidney-friendly diet that works for everyone.
Some people need to adjust their sodium, potassium, phosphorus, or protein intake, while others may not need restrictions on every nutrient.
Dietary recommendations should be based on kidney function, blood test results, medications, nutritional needs, and guidance from a qualified healthcare professional.
The goal is to support kidney and cardiovascular health without unnecessarily restricting foods or increasing the risk of malnutrition.
Foods and Nutrients to Consider
| Nutrient or Food Component | Why It Matters | Practical Approach |
|---|---|---|
| Sodium | Excess sodium can contribute to high blood pressure and fluid retention, placing additional stress on the kidneys and heart. | Reduce highly processed foods, salty snacks, processed meats, and high-sodium sauces. Use herbs, garlic, lemon, and other salt-free seasonings for flavor. |
| Phosphorus | When kidney function declines, phosphorus may accumulate in the blood and contribute to bone and mineral complications. | Check food labels for phosphate additives, especially in processed meats and packaged foods. Restriction should depend on clinical needs and laboratory results. |
| Potassium | Both high and low blood potassium levels can be dangerous. Kidney disease and certain medications can affect potassium balance. | Adjust potassium intake only when appropriate. Ask your healthcare team which fruits, vegetables, and other foods fit your laboratory results and treatment plan. |
| Carbohydrates and Added Sugars | The amount and type of carbohydrate consumed can influence blood glucose levels. | Favor minimally processed, fiber-rich carbohydrate sources in portions that fit your diabetes management plan. Limit sugar-sweetened drinks and excessive added sugars. |
| Protein | Protein is essential for maintaining muscles and repairing body tissues, but excessive intake may be unsuitable for some people with CKD. | Follow an individualized protein target. Avoid severe protein restriction without professional guidance, because inadequate intake can contribute to malnutrition. |
For more detailed recommendations, see the NIDDK guide to healthy eating for adults with chronic kidney disease.
Understanding Protein Intake
Protein deserves particular attention when diabetes and kidney disease occur together.
The body needs protein to maintain muscle, support immune function, and repair tissues.
However, people with CKD who are not receiving dialysis may need to avoid excessive protein intake.
Current guidance does not support automatically reducing protein below recommended levels for every person with diabetic kidney disease.
The appropriate amount depends on kidney function, nutritional status, age, activity level, and other health considerations.
People receiving dialysis may have different protein requirements because treatment can remove protein from the body.
Therefore, protein recommendations for someone with advanced CKD who is not receiving dialysis should not automatically be applied to someone receiving dialysis.
A renal dietitian can help determine suitable protein portions and sources while ensuring that meals provide enough calories and essential nutrients.
Why Individualized Nutrition Matters
Restricting potassium, phosphorus, or protein without a clear medical reason can make an already complicated diet unnecessarily difficult.
Some restrictions may be needed when laboratory results or clinical circumstances indicate a problem, but they should not be assumed to apply to every person with diabetic kidney disease.
For example, a person with elevated blood potassium may need specific dietary adjustments, while another person with CKD may not require the same restrictions.
Similarly, fluid intake should be individualized rather than automatically limited for everyone with kidney disease.
A practical approach is to review food choices with a registered dietitian experienced in diabetes and kidney care.
This helps balance blood glucose management, kidney health, adequate nutrition, personal food preferences, and cultural eating habits.
The American Diabetes Association’s Standards of Care in Diabetes—2026 emphasizes individualized nutrition and management of kidney-related risks.
Working with your healthcare team can help turn these recommendations into a realistic eating plan that supports long-term health.
How to Protect Kidney Health With Type 2 Diabetes
People living with type 2 diabetes can take practical steps to reduce their risk of kidney complications.
For those who already have diabetic kidney disease, appropriate treatment and regular monitoring can help slow progression and reduce the risk of additional health problems.
Although no routine can guarantee that kidney disease will be prevented, managing blood glucose and blood pressure, using appropriate medications, and attending regular screening appointments can make an important difference.
1. Manage Blood Pressure and Blood Glucose
High blood pressure and elevated blood glucose can contribute to kidney damage over time.
Keeping both under control is an important part of diabetes care.
Your healthcare team can help establish appropriate blood pressure and blood glucose targets based on your age, kidney function, cardiovascular health, medications, and risk of low blood glucose.
For some people with diabetes, blood pressure medication may also provide kidney protection.
ACE inhibitors or angiotensin receptor blockers (ARBs) are particularly important for eligible patients with hypertension and elevated urine albumin levels.
However, these medications are not recommended solely to prevent kidney disease in every person with diabetes.
Take prescribed medication as directed and discuss any side effects or concerns with your healthcare professional rather than changing treatment independently.
2. Schedule Regular Blood and Urine Tests
Kidney disease may develop without noticeable symptoms, so screening is essential.
Two important tests are:
- Estimated glomerular filtration rate (eGFR): A blood-based estimate of how effectively the kidneys filter waste.
- Urine albumin-to-creatinine ratio (UACR): A urine test that detects elevated albumin, a protein that can appear in urine when kidney damage is present.
The American Diabetes Association recommends checking eGFR and UACR at least annually in people with type 2 diabetes.
Once chronic kidney disease is established, testing may be needed more frequently depending on the disease stage and risk of progression.
If a result is abnormal, your healthcare professional may recommend repeat testing or further evaluation.
One abnormal result does not always establish a diagnosis.
See the American Diabetes Association’s Standards of Care in Diabetes—2026 for current screening and monitoring recommendations.
3. Follow an Individualized Hydration Plan
Adequate fluid intake supports normal body function, but drinking more water does not automatically improve kidney function or prevent diabetic kidney disease.
Fluid needs vary according to kidney function, heart health, medications, urine output, and other medical conditions.
Some people with advanced kidney disease or heart failure may need fluid restrictions, while others may not.
Drink according to your individual needs and your healthcare team’s recommendations.
If you have been advised to restrict fluids, do not increase your intake without discussing it with your healthcare professional.
4. Build Sustainable Daily Habits
Daily habits can complement medical treatment and help manage cardiovascular and kidney risks.
Practical steps include:
- Choose balanced meals that support blood glucose and blood pressure management.
- Reduce excessive sodium intake, especially from highly processed foods.
- Maintain physical activity appropriate for your health and mobility.
- Avoid tobacco and seek support if you need help quitting.
- Take medications consistently and attend scheduled medical appointments.
- Tell your healthcare team about supplements, herbal products, and over-the-counter pain medicines you use.
These steps should support—not replace—evidence-based medical care.
5. Review Your Kidney Health Plan Regularly
Diabetic kidney disease management may change as kidney function, blood pressure, blood glucose, and other health conditions evolve.
Ask your healthcare team how often you should have kidney tests, whether your medications remain appropriate, and whether you need additional treatment to protect kidney and cardiovascular health.
If your urine albumin levels rise, your eGFR declines, or you develop other complications, your care team may adjust your treatment plan or refer you to a nephrologist.
The aim is to identify changes early, manage risk factors, and make informed decisions before complications become more difficult to control.
Can Type 1 Diabetes Cause Kidney Disease?
Yes.
Type 1 diabetes can cause chronic kidney disease (CKD) when persistently elevated blood glucose contributes to damage in the kidneys’ small blood vessels over time.
High blood pressure and other health factors can also increase the risk of kidney complications.
Kidney disease does not develop in everyone with type 1 diabetes.
The risk varies according to factors such as blood glucose management, blood pressure, genetics, and other medical conditions.
When Should People With Type 1 Diabetes Start Kidney Screening?
The American Diabetes Association’s Standards of Care in Diabetes—2026 recommends assessing kidney function with a blood test for estimated glomerular filtration rate (eGFR) and a urine albumin-to-creatinine ratio (UACR) at least annually once a person has had type 1 diabetes for five years or longer.
These tests help identify reduced kidney filtration or elevated urine albumin, which may indicate kidney damage.
Because early kidney disease often has no obvious symptoms, regular screening is important even when a person feels well.
If test results are abnormal, a healthcare professional may recommend repeat testing, additional evaluation, or changes to the treatment plan.
How Can People With Type 1 Diabetes Protect Their Kidney Health?
Several measures can help reduce the risk of kidney complications:
- Manage blood glucose: Follow an individualized diabetes treatment plan, including insulin and glucose monitoring as prescribed.
- Monitor blood pressure: Work with your healthcare team to maintain an appropriate blood pressure range.
- Attend regular kidney screenings: Keep up with recommended eGFR and UACR testing.
- Follow a balanced eating plan: Choose foods that support diabetes management and adjust the diet if kidney-related complications require specific changes.
- Review medications and supplements: Tell your healthcare team about all medicines, herbal products, and supplements you use.
These measures can reduce risk, but they cannot guarantee that kidney disease will be prevented.
If kidney abnormalities develop, early evaluation and appropriate treatment can help manage the condition and reduce the risk of further complications.
For additional information, consult the American Diabetes Association’s kidney disease and risk management recommendations.
Emotional Well-Being and Following Diabetic Kidney Disease Management Guidelines
Living with diabetes and managing the risk of kidney disease can be emotionally challenging.
Regular appointments, blood and urine tests, medication schedules, and dietary recommendations may sometimes feel overwhelming.
It is understandable to experience worry, frustration, or uncertainty while navigating these responsibilities.
Following diabetic kidney disease management guidelines does not mean that you must manage everything perfectly every day.
Kidney health is influenced by many factors, including genetics, other medical conditions, and how the disease progresses.
Developing kidney complications does not necessarily mean that someone has failed to take care of their health.
Building Sustainable Daily Routines
Rather than trying to change everything at once, focus on manageable steps that fit your circumstances.
Taking prescribed medications as directed, attending medical appointments, following an individualized eating plan, and keeping track of important test results can help you stay involved in your care.
It may also help to prepare questions before appointments, use reminders for medications, or ask a trusted family member to assist with practical tasks.
Small organizational changes can make a complex care plan feel more manageable.
Remember that treatment recommendations may change over time.
If a particular routine becomes difficult to maintain, discuss it with your healthcare team.
They may be able to adjust the plan or connect you with additional support.
Seeking Emotional and Practical Support
You do not have to navigate diabetes and kidney health concerns alone.
Talking with family members, trusted friends, diabetes educators, renal dietitians, or other healthcare professionals may help you manage practical challenges and feel better supported.
If anxiety, sadness, or stress begins to interfere with sleep, relationships, daily activities, or diabetes self-management, consider discussing these concerns with a healthcare professional.
Psychological support can be part of comprehensive chronic disease care.
Taking a Compassionate Approach to Kidney Health
The purpose of diabetic kidney disease management guidelines is to support informed decisions and appropriate treatment—not to create a sense of guilt or pressure.
Focus on what you can reasonably manage, ask questions when something is unclear, and work with your healthcare team to review your progress.
Even when kidney disease cannot be completely prevented, appropriate care can help manage risk factors, address complications, and support your overall well-being.
Taking care of your emotional health is one part of living with a chronic condition.
Give yourself room to learn, adapt, and seek help when you need it.

Frequently Asked Questions
How are diabetes and kidney disease treated together?
Treatment focuses on managing blood glucose, controlling blood pressure, reducing cardiovascular risk, and monitoring kidney function.
Depending on the patient’s condition, healthcare professionals may prescribe ACE inhibitors or ARBs, SGLT2 inhibitors, GLP-1 receptor agonists, or other medications with demonstrated benefits.
Not everyone needs every medication.
Treatment choices depend on factors such as diabetes type, blood pressure, estimated glomerular filtration rate (eGFR), urine albumin levels, and other medical conditions.
Regular blood and urine tests help healthcare professionals evaluate whether the treatment plan is working and whether adjustments are needed.
For more information, see the American Diabetes Association’s Standards of Care in Diabetes—2026.
What foods should diabetics with kidney disease avoid?
There is no universal list of foods that every person with diabetes and kidney disease must avoid.
However, limiting excessive sodium and reducing highly processed foods can help support blood pressure and cardiovascular health.
Depending on kidney function and laboratory results, some people may also need to adjust their potassium, phosphorus, or protein intake.
Carbohydrate portions should be managed as part of an individualized diabetes eating plan.
Avoid making severe dietary restrictions without professional guidance.
A renal dietitian can help develop a balanced eating plan that supports blood glucose management, kidney health, and adequate nutrition.
Read the NIDDK guide to healthy eating for adults with chronic kidney disease.
How can people with type 2 diabetes reduce their risk of kidney disease?
Important steps include managing blood glucose and blood pressure, taking prescribed medications as directed, avoiding tobacco, maintaining appropriate physical activity, and attending regular kidney screening appointments.
People with type 2 diabetes should generally have their kidney function assessed at least annually using a blood test for eGFR and a urine test for the urine albumin-to-creatinine ratio (UACR).
People with established kidney disease may need more frequent monitoring.
These measures can help reduce the risk of kidney complications, although they cannot guarantee that kidney disease will be prevented.
Can type 1 diabetes cause kidney disease?
Yes.
Type 1 diabetes can damage the kidneys over time, particularly when elevated blood glucose and other risk factors are not adequately managed.
However, kidney disease does not develop in everyone with type 1 diabetes.
The American Diabetes Association recommends kidney screening beginning after five years of type 1 diabetes, with eGFR and UACR generally assessed at least annually thereafter.
Earlier or additional testing may be appropriate if there are specific clinical concerns.
Good diabetes management and regular screening can help identify kidney problems early and guide appropriate treatment.
For more details, consult the American Diabetes Association’s kidney disease and risk management recommendations.
What is the earliest sign of kidney strain in diabetes?
One of the earliest detectable markers is an elevated urine albumin-to-creatinine ratio (UACR), which indicates that more albumin than expected is passing into the urine.
This can occur before noticeable symptoms or a substantial decline in eGFR.
However, not everyone with diabetic kidney disease develops elevated urine albumin, and a single abnormal test does not always confirm a diagnosis.
Healthcare professionals may repeat testing and consider other clinical findings.
Because early kidney disease often causes no obvious symptoms, regular blood and urine screening is important even when a person feels well.
