Diabetes and gangrene

Peripheral arterial disease caused by atherosclerosis is more likely to affect diabetics. This condition impairs the circulation in arteries, most notably the ones leading to the brain, legs and feet.

This often happens during the normal ageing process, but high blood-sugar levels compound this process. The nerve damage that this condition causes can also lead to impotence.

This condition can lead to strokes and injuries that don't heal and, in a worst-case scenario, to gangrene, which might necessitate amputation. Much can be done to prevent this, and footcare is at the top of the list.

Small cuts, blisters, Plantar’s warts and ingrown toenails can lead to a minor infections, followed by a bacterial invasion. Nerve loss can also make you unaware of developing sores, deep ulcers, or slightly infected cuts. Severe sores that don’t heal can become gangrenous and lead to amputations.

Diabetics should take extra care to buy well-fitting shoes, and not neglect any cuts or blisters. It's preferable to have toenails cut by a professional.

When tingling sensations, or burning and pain is felt in the lower legs and feet, it's a good idea to see your doctor. Nerve loss can also make you unaware of developing sores or slightly infected cuts. Severe sores that don’t heal can become gangrenous and lead to amputations.
