Diabetic Angiopathy! What You Need to Know

Have you ever heard of diabetes causing complications beyond just blood sugar spikes? One such complication is diabetic angiopathy, and it’s not something to take lightly. Think of it as high blood sugar wreaking havoc on your blood vessels, like tiny highways clogging up. This can lead to serious problems down the road, affecting different parts of your body.

A white board with the title What You Need to Know About Diabetic Angiopathy and its different types.

How High Blood Sugar Damages and Different Types of Diabetic Angiopathy

So, how exactly does high blood sugar damage your blood vessels? Imagine the inner lining of your vessels, called the endothelium, as a smooth road for blood to flow freely. Chronically high blood sugar levels act like tiny pebbles, constantly hitting and damaging this smooth surface. Over time, this damage can lead to:

  • Inflammation: The body tries to repair the damage, but this can lead to further inflammation and narrowing of the vessels.
  • Stiffness: The vessels lose their elasticity and become more rigid, making it harder for blood to flow through.
  • Fatty Deposits: The damaged endothelium becomes a breeding ground for cholesterol and other fatty substances, further clogging the vessels.

Now, this damage doesn’t happen uniformly throughout the body. Depending on which vessels are affected, different types of diabetic angiopathy can occur:

  • Diabetic Retinopathy: This affects the blood vessels in the retina, the light-sensitive layer at the back of the eye. It can lead to blurry vision, bleeding in the eye, and even blindness if left untreated.
  • Diabetic Nephropathy: This targets the blood vessels in the kidneys, hindering their ability to filter waste products from the blood. This can eventually lead to kidney failure.
  • Diabetic Neuropathy: This affects nerves throughout the body, causing numbness, tingling, pain, and weakness, especially in the feet and legs.
  • Diabetic Foot Disease: This is a combination of nerve damage and poor blood circulation in the feet, increasing the risk of infections, ulcers, and even amputation if not managed properly.

These are just some of the most common types, and diabetic angiopathy can affect other parts of the body as well. By understanding the different types and how they arise, you can appreciate the importance of managing your blood sugar and preventing this serious complication.


While high blood sugar plays the starring role in causing diabetic angiopathy, it’s not the only culprit on stage. Several other factors contribute to this condition, making it even more crucial to manage your overall health:

  • High blood pressure: Over time, uncontrolled high blood pressure puts additional strain on your already weakened blood vessels, accelerating the damage caused by high blood sugar.
  • High cholesterol: Similar to high blood pressure, high cholesterol levels can lead to the formation of plaque, further narrowing the blood vessels and restricting blood flow.
  • Smoking: This harmful habit significantly contributes to various health problems, including damaging blood vessel walls and reducing blood flow. It’s especially detrimental for people with diabetes, as it can worsen the existing complications.

You can significantly reduce your risk of developing or worsening diabetic angiopathy, by addressing these contributing factors alongside managing your blood sugar. We should remember, that prevention is always better than cure.

Symptoms of Diabetic Angiopathy

The symptoms of diabetic angiopathy vary depending on the affected area. Here’s a breakdown of some common signs to be aware of:

Diabetic Retinopathy:

  • Blurred vision: This can be a gradual change or happen suddenly.
  • Floaters: Seeing dark spots or squiggly lines that float in your vision, especially noticeable when looking at a bright light background.
  • Difficulty seeing at night: Your vision may become blurry or dimmed in low-light conditions.
  • Sudden vision loss: This is a serious symptom and requires immediate medical attention.

Diabetic Nephropathy:

  • Frequent urination, especially at night (nocturia): You may need to urinate more often than usual, especially during the night.
  • Foamy urine: This can be a sign that protein is leaking from your kidneys into your urine.
  • Feeling tired and weak: This can be caused by anemia, a condition where your blood doesn’t have enough red blood cells to carry oxygen throughout your body.
  • High blood pressure: Uncontrolled high blood pressure can further damage your kidneys.
  • Swollen ankles and feet: This can be caused by fluid buildup due to impaired kidney function.

Diabetic Neuropathy:

  • Numbness, tingling, or burning sensation in the hands and feet: This can start gradually and worsen over time. You may also experience a pins-and-needles or prickling sensation.
  • Pain, especially at night: The pain can be sharp, burning, or throbbing, and it may be worse at night or when resting.
  • Weakness: You may experience muscle weakness, especially in the legs and feet.
  • Increased risk of foot infections: Due to nerve damage, you may not feel cuts or sores on your feet, which can lead to infections that are slow to heal and potentially serious.

Diabetic Foot Disease:

  • Slow-healing sores or ulcers on the feet: These can develop due to poor circulation and nerve damage that reduces your ability to feel pain.
  • Numbness in the feet: This can make it difficult to feel injuries or changes in temperature, which can increase the risk of infection.
  • Changes in skin color or temperature: The skin on your feet may become red, pale, or cool to the touch.
  • Foot pain, especially when walking: You may experience pain, cramping, or burning in your feet, especially when walking or standing for long periods.

Remember, early diagnosis and proper management can significantly improve your quality of life and prevent the progression of diabetic angiopathy.


While symptoms offer clues, specific tests confirm the extent of damage and guide treatment. These tests are typically painless and non-invasive. Examples include:

  • Eye exams: A comprehensive dilated eye exam, often involving a test called fluorescein angiography, is used to diagnose diabetic retinopathy.
  • Urine and blood tests: These can include tests for urinary albumin-to-creatinine ratio (UACR) and glomerular filtration rate (GFR) to assess kidney function for diabetic nephropathy.
  • Physical exams and nerve tests: These may involve tests like monofilament testing to assess feeling in the feet, vibration testing using a tuning fork, and electromyography (EMG) to measure nerve function, for diagnosing diabetic neuropathy.
  • Foot exams: A thorough foot exam by a healthcare professional is crucial for early detection of diabetic foot disease.

If you feel or see any symptoms we discussed above, do not wait a single moment to start the diagnosis process. Early detection can prevent a huge percentage of damage you can’t even imagine.

Treatment Options

The good news is that although there’s no cure for diabetic angiopathy, there are ways to manage it and prevent further complications. The cornerstone of treatment lies in effectively managing your blood sugar levels. This can be achieved through:

  • Medications: Depending on your specific needs, your doctor may prescribe medications like:
    • Insulin: Injected forms of insulin, such as glargine (Lantus) or lispro (Humalog), can help regulate blood sugar levels throughout the day.
    • Oral medications: These include various classes of drugs like metformin (Glucophage), sulfonylureas (glipizide [Glucotrol], glimepiride [Amaryl]), DPP-4 inhibitors (sitagliptin [Januvia]), and SGLT2 inhibitors (dapagliflozin [Farxiga]), which work in different ways to regulate blood sugar levels.
  • Lifestyle changes: Maintaining a healthy lifestyle, including a balanced diet, regular physical activity, and maintaining a healthy weight, plays a crucial role in managing blood sugar and overall health.

However, depending on the specific type and severity of diabetic angiopathy, additional treatment options may be necessary:

  • Diabetic retinopathy: If caught early, laser treatment or injections of medications like anti-VEGF agents (aflibercept [Eylea]) into the eye can help prevent vision loss. In severe cases, surgery may be needed.
  • Diabetic nephropathy: Medications like blood pressure medications (ACE inhibitors or ARBs) and medications to control protein in the urine (SGLT2 inhibitors) can help slow the progression of kidney damage. In advanced cases, dialysis or kidney transplants may be needed.
  • Diabetic neuropathy: Medications like duloxetine (Cymbalta) or pregabalin (Lyrica) can help manage pain and nerve damage. Proper foot care, including routine inspections and wearing appropriate footwear, is crucial to prevent infections and ulcers.
  • Diabetic foot disease: Depending on the severity, treatment may involve antibiotics for infections, wound care, or even surgery, including amputations in worst-case scenarios.

Remember, early detection and prompt intervention are key to managing diabetic angiopathy effectively and avoiding complications. By working closely with your healthcare team, you can take control of your health and maintain a good quality of life.

Protecting Yourself from Diabetic Angiopathy

While there’s no guaranteed way to prevent diabetic angiopathy entirely, the good news is that you have significant power to reduce your risk. Here’s how:

  • Maintain good blood sugar control: This remains the most crucial step. By diligently following your doctor’s recommendations on medication, diet, and lifestyle, you can significantly reduce your risk of developing or worsening diabetic angiopathy.
  • Embrace a healthy lifestyle: Make healthy habits your allies:
    • Regular exercise: Make a target for at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous-intensity exercise per week. Even small activities like taking a brisk walk daily can make a difference.
    • Balanced diet: Focus on a balanced diet that includes plenty of fruits, vegetables, and whole grains while limiting processed foods, added sugars, and unhealthy fats. Consult a registered dietitian for personalized guidelines.
    • Maintain a healthy weight: If you’re overweight or obese, losing even a modest amount of weight can significantly improve your blood sugar control and overall health.
    • Quit smoking: Smoking significantly increases your risk of various health complications, including diabetic angiopathy. Quitting smoking is one of the best things you can do for your overall well-being.

By prioritizing these healthy habits, you’re not just preventing diabetic angiopathy; you’re investing in your overall well-being and setting yourself up for a healthier future.
