What is diabetic neuropathy?

Diabetic neuropathy is a type of nerve damage caused by diabetes.1 High blood sugar levels injure small blood vessels supplying the nerve fibres, leading to nerve damage.2 Nerve fibres throughout the body can be damaged, but this condition commonly affects nerves in the legs and feet.1

Although diabetic neuropathy is a serious complication, it can be prevented, or its progression can be slowed with good blood sugar control and a healthy lifestyle.1

What are the symptoms of diabetic neuropathy?

Symptoms depend on1:

  • The type of neuropathy
  • The affected nerves
What is diabetic neuropathy?

Main types of neuropathy:

1. Sensory

  • Damage to the nerves which detect touch, temperature and
    pain. Commonly affects the feet and legs, but can also
    affect the arms and hands2
  • Symptoms2,3:
    • Tingling and prickling sensation (pins and needles)
    • Numbness, reduced ability to feel pain (or) temparature changes
    • Loss of coordination
    • Burning or shooting pains
    • Pain from stimuli that do not usually cause pain at all, eg, light touch
  • Loss of feeling in the feet—not realizing this is dangerous, because minor
    injuries may go unnoticed. Untreated minor injuries can progress to infections,
    ulcers or gangrene. Infections that spread and cause tissue death can
    become untreatable and may require toe, foot or lower leg amputation1,2
