Having diabetic triopathy requires managing the symptoms of diabetes-related neuropathy, retinopathy and nephropathy. Handling all these conditions can be stressful. A diverse medical team can be comforting. It can also help slow the progression of your symptoms.

More than 38 million people in the U.S. have diabetes. That’s nearly 12% of the population.1 Many people don’t understand how this disease can affect the body. They might also not know about diabetic triopathy, a group of conditions that can affect their health.

First, diabetes is a condition that includes high blood sugar (glucose).2 The pancreas makes insulin to control blood sugar. It turns the sugars from food into energy. Some people with diabetes can’t make enough insulin. Others can’t use it efficiently. Diabetes increases blood sugar levels to unhealthy and dangerous levels.

Regular checkups and blood tests can help you detect the early signs of diabetes. If you have diabetes, regular monitoring helps you get the care you need. Doing so can lower your likelihood of related complications. Untreated diabetes often leads to other health problems that affect many organs. These include kidney failure, blindness, nerve damage and heart disease.

Diabetes also increases your risk for diabetic triopathy. This group includes blood vessel disorders like diabetes-related neuropathy, retinopathy and nephropathy.

We explain diabetic triopathy and go over its symptoms and causes. We also discuss how you can get early diagnosis and treatment if you live with diabetes. Finally, we highlight the importance of medical monitoring and prevention.

What is diabetic triopathy?

You may be familiar with diabetes, but you might wonder, “What is diabetic triopathy?” Experts have used the term since the 1950s. It explains how people with diabetes first develop neuropathy, retinopathy and then nephropathy.3 However, these three diseases may not show up in this order.

Hyperglycemia, or high blood sugar, links these conditions.4 It occurs in diabetes and harms blood vessels. These vessels move oxygen and nutrients to all the organs. Here’s an explanation of each condition:

  • Neuropathy—Damaged blood vessels can’t feed the nerves. This causes pain, numbness and tingling, especially in the feet.
  • Retinopathy—Blood vessels in the eyes get weak. This causes swelling, leaking into the eye or retinal detachment.5 The damage harms vision and causes blindness in some patients.6
  • Nephropathy—This is also known as diabetes-related kidney disease. Kidney function breaks down when high blood sugar levels hurt the small blood vessels in the kidneys.7

Knowing how these conditions relate can help you receive proper diabetic care. It can also reduce long-term damage.

Causes and risk factors

High blood sugar can lead to diabetic triopathy. Other causes include high blood pressure and how long you’ve had diabetes. Let’s explore the risk factors of each diabetes-related condition.

Neuropathy

About 50% of people with diabetes develop neuropathy.8 It sometimes comes from pinched nerves, nutritional deficiencies or inflammation. However, providers usually point to diabetes if they can’t determine other causes.

High blood sugar is a common cause of blood vessel damage. This damage causes the vessels to die. Dead blood vessels can lead to pain, swelling and tingling.

Healthy blood sugar levels (A1C) are below 5.7%. A person with type 2 diabetes who has an A1C above 7% for at least 3 years is more likely to have diabetic neuropathy.9 Other risk factors include

  • Alcohol use disorder
  • Genetics
  • Hypertension
  • High body mass index (BMI)
  • High cholesterol
  • Kidney disease
  • Smoking8

Retinopathy

Diabetic retinopathy is the leading cause of blindness in the U.S.6. It affects about 25% of people with diabetes.10 High blood sugar due to diabetes is the primary cause. Decreased blood flow to the vessels in the eyes damages the retina.5 The retina is the part of the eye that picks up light and sends signals to your brain. This happens through the optic nerve at the back of the eye.

To make up for vessel damage, your eyes create new blood vessels that are less effective but bleed more. Having type 1, type 2 or gestational (during pregnancy) diabetes puts you at risk for diabetic retinopathy. This risk increases with

  • Advanced age
  • Being male
  • Diabetic neuropathy
  • High blood pressure
  • High BMI
  • High duration of diabetes11

Nephropathy

About 40% of individuals with diabetes have nephropathy. This is the most common cause of end-stage kidney failure in the world.7 Type 1 and type 2 diabetes are significant risk factors for nephropathy. Your chances are even greater if you’re Black, Native American, Alaska Native, Polynesian or Maori. Additional causes are

  • Family history of kidney disease
  • High blood pressure
  • High cholesterol levels
  • High blood glucose
  • Tobacco use12

Symptoms and warning signs

Knowing the early signs of diabetic triopathy can lead to earlier diagnosis and more effective treatment. Detection at the earliest stages can prevent severe damage. It can also slow the progression of the damage. Here are the warning signs for each condition.

Neuropathy

Nerve damage from diabetic neuropathy might not show up for years.8 It takes some people a long time to show symptoms. People with diabetes should regularly check for the following:

  • Burning, shooting or stabbing pain
  • Food or leg sores that take a long time to heal
  • Losing sensation in the feet, or feeling little or no pain from injury
  • Muscle weakness
  • Numbness or tingling
  • Unusual sensations from touch (dysesthesia)

Retinopathy

Instead of age-related vision decline, you may actually have diabetic retinopathy. However, there are no early warning signs.5 A yearly eye exam is essential if you have diabetes. Staying alert for any changes in your eye health can help protect your vision.

Nephropathy

As with retinopathy, diabetic nephropathy usually doesn’t have early symptoms. One sign may be high urinary protein levels. However, a layperson cannot detect this without a urine test.7

For most people with diabetic nephropathy, symptoms show up after 80-90% of the kidneys are damaged.7 During the later stages, you may notice:

  • Low appetite
  • Difficulties concentrating
  • Dry, itchy skin
  • Dyspnea, or shortness of breath
  • Edema, which is swelling in the face, hands and feet
  • Fatigue
  • Foamy urine
  • Muscle cramps
  • Nausea or vomiting
  • More frequent urination
  • Reduced need for insulin

Early treatment for diabetic nephropathy lowers your risk of kidney failure, which can be fatal.

Diagnosis and monitoring

Managing diabetes requires comprehensive treatment. This includes regular doctor visits every 3-6 months. Your provider may suggest more frequent checkups if you have certain risk factors. Let’s review how to diagnose and monitor each condition.

Neuropathy

To diagnose diabetic neuropathy, your doctor will perform a physical exam. They’ll also review your medical history and ask about your symptoms. Other tests include

  • Diabetes foot exam—Checking for numbness, injuries, sores and other problems.
  • Electromyography (EMG)—Examining the muscles, bones and connected nerves.
  • Gastric emptying scintigraphy (GES)—Looking for nerve-related issues in the digestive system.
  • Nerve conduction studies (NCS)—Determining how quickly electrical signals move through the nerves throughout the body.8

Retinopathy

Retinopathy can’t be reversed, but early detection can help you prevent further damage and avoid blindness. Annual eye exams can help spot retinopathy in its early stages. A painless dilated eye exam involves applying eyedrops to widen the pupils and give a view of the retina.

To diagnose severe diabetic retinopathy, your eye doctor may order a fluorescein angiogram.5 This test allows for viewing the blood vessels in the retina.

Nephropathy

One test for nephropathy is an estimated glomerular filtration rate (eGFR). This measures your kidneys’ ability to clean your blood.7 It requires drawing a small amount of blood from your arm.

Your doctor might order a urine test to look for microscopic signs of nephropathy. They may also perform an ultrasound, magnetic resonance imaging (MRI) or computed tomography (CT) scans to find damage. Another method is a kidney biopsy. For this test, the doctor removes a small tissue sample from the kidney to look at it under a microscope.7

Treatment and management

Living with diabetic triopathy doesn’t have to mean a lower quality of life. Keeping glucose levels healthy is the most crucial step to protecting your blood vessels and preventing future damage.

The American Diabetes Association (ADA) suggests striving for an A1C of 7.0% or lower.13 Try to keep your blood sugar levels between 80 and 130 milligrams per deciliter (mg/dL) before meals. Your number should stay below 180 mg/dL up to 2 hours after eating.

Successful diabetes management also requires the following:

  • Regular exercise
  • Blood pressure and cholesterol control
  • Not smoking or using tobacco products
  • Maintaining a healthy weight
  • Eating foods rich in fiber and low in fats and processed sugars7, 12

If you live with diabetic triopathy, you should work with many different providers.4 In addition to your primary doctor, your care team should include

  • Certified diabetes educator
  • Endocrinologist (a doctor who treats glandular conditions, including high blood sugar)
  • Nephrologist (kidney doctor)
  • Ophthalmologist or optometrist (eye doctor)
  • Podiatrist (foot and ankle doctor)
  • Registered dietician or nutritionist

Other providers should include your dentist, registered nurse (RN), pharmacist, mental health provider and personal trainer.14

Neuropathy

Your doctor may recommend several ways to control your symptoms.8 These can include medications for pain. You can work with a physical therapist to improve your mobility. An occupational therapist will ensure you can perform everyday tasks, such as dressing, bathing or going to the bathroom.

Retinopathy

Schedule eye exams every 2 to 4 months to catch retinopathy early.5Also, keep your cholesterol and blood pressure in check.

In the later stages of retinopathy, you may notice vision changes. Your doctor may suggest more aggressive treatments to prevent further damage, such as

  • Eye surgery to address retinal bleeding and scar tissue in the eye.
  • Injections, such as corticosteroids, that slow down or reverse some of the damage.
  • Laser treatments to reduce retinal swelling and bleeding.

Nephropathy

You can’t reverse diabetic nephropathy. However, early treatment can slow progression and improve your quality of life. Treatment success depends on how well you manage your diabetes.

Nephrology management focuses on preventing further kidney damage. Avoid using aspirin, ibuprofen and anti-inflammatory drugs. They can cause kidney damage.12

People with advanced diabetic nephropathy have other treatment options. One is kidney dialysis.7 This is needed when the kidneys can’t work on their own. During dialysis, a machine takes out your blood, removes waste and returns it to your body. An alternative is a kidney transplant, which comes from a healthy live donor.

Prevention strategies

You can prevent diabetic triopathy by managing your diabetes and adopting healthy habits. Form a strong relationship with your doctor and other members of your care team. Ask lots of questions and follow your treatment plan closely. Also, do the following:

  • Watch your blood sugar levels closely. Keep your A1C below 7.0% or at or below the level your physician indicates.
  • Take all your medications as your doctors prescribe them.
  • Keep your blood pressure below 140/90 or below your doctor’s recommended target.
  • Keep your weight at a healthy level for your height and body type.
  • Follow a healthy diet. Seek help from your nutritionist and diabetes educator.
  • Avoid or limit alcoholic beverages. Stay away from all tobacco products.v
  • Schedule a wellness checkup with your primary care provider yearly or more often if necessary.
  • Exercise for at least 30 minutes daily, at least 5 days of the week, or according to your doctor’s advice. Choose an activity that you enjoy so that you stick with it.7

Here are some prevention strategies for each diabetic condition:

Neuropathy

Schedule an exam with your foot doctor at least once a year. Check your feet every day for slow-healing ulcers, sores, wounds, blisters or broken skin.8

Retinopathy

Keep up with your regular eye exams to catch vision problems early. Even if you treat prior retinal damage, it can come back. Control your blood pressure and cholesterol levels to stay ahead of potential eye problems.6

As we pointed out, pregnancy increases your risk of diabetic retinopathy.5 If you become pregnant or have a history of gestational diabetes, get an eye exam as soon as possible.

Nephropathy

Get nephropathy testing every 5 years after your diabetes diagnosis. Kidney damage typically doesn’t appear within the first 10 years of diabetes. However, testing every 5 years can help you catch it early. If you live with diabetes for more than 25 years without kidney damage, you’re less likely to develop diabetic nephropathy in the future.7

Summary

Having diabetic triopathy requires managing the symptoms of diabetes-related neuropathy, retinopathy and nephropathy. Handling all these conditions can be stressful. A diverse medical team can be comforting. It can also help slow the progression of your symptoms.
