Managing Type 2 Diabetes Complications

Type 2 diabetes affects more than blood sugar. Over time, high or fluctuating blood glucose can damage blood vessels and nerves, leading to complications. The good news is that early recognition and consistent daily care can slow or prevent many problems.

This guide explains common complications and what you can do — starting today — to protect your health.

Why Diabetes Complications Happen

When blood sugar stays high over time, it can:

• Damage small blood vessels
• Reduce blood flow
• Injure nerves
• Strain organs like the eyes and kidneys

Managing diabetes well is about more than numbers — it’s about protecting how your body functions day to day.

Some Common Diabetes Complications Explained

Diabetic Neuropathy (Nerve Damage)

Neuropathy most often affects the feet and legs, but can also involve hands and digestion.

Common symptoms:

• Numbness or tingling
• Burning or sharp pain
• Reduced ability to feel temperature or injury
• Balance problems

⚠️ Loss of sensation increases the risk of unnoticed injuries and infections.

Diabetic Retinopathy (Eye Damage)

High blood sugar can damage the tiny blood vessels in the eyes.

Possible signs:

• Blurry or fluctuating vision
• Trouble seeing at night
• Dark spots or floaters
• Vision loss (often late)

💡 Early stages may have no symptoms, which is why routine eye exams matter.

Diabetic Nephropathy (Kidney Damage)

Diabetes is a leading cause of kidney disease.

Warning signs may include:

• Swelling in feet or ankles
• Foamy urine
• Fatigue
• Changes in urination

⚠️ Kidney damage often develops silently and is detected through lab tests.
