Diabetes is the failure of the body to use carbohydrates and sugars properly. Nutrition to all the cells of the body becomes compromised. Three common complications arise from diabetes: Nephropathy (destruction of kidney tissue), retinopathy (destruction of the retina in the eye) and peripheral neuropathy (destruction of the nerves leading to the lower extremities). Pedorthists are involved with diabetics in the management of peripheral neuropathy. Once damaged, nerves in the legs and feet not only lose feeling (sensory loss) but balance and gait are detrimentally affected. Damage to the soft tissues leads to joint stiffness and loss of normal toe function. The fat pad in the forefoot is lost and skin growth in that area is deficient. Heavy calluses and foot ulcers can develop in this area of tissue vulnerability. Those with sensory loss in their feet can even have foreign objects in their shoes or sores on their feet without being aware of it.
Progression of peripheral neuropathy and foot problems correspond to inadequate control of blood sugar levels. The diabetic foot is at risk for very disabling results, such as a Charcot foot, ulcers and amputation if blood sugar levels are not controlled and proper foot care is not maintained.
Other names or similar foot conditions:
- Diabetes Type I and Type II
- Juvenile diabetes (Type I) and Adult on-set diabetes (Type II)
- Charcot foot (see that section for more information)
Symptoms:
- Sensory loss in feet
- Loss of position awareness and balance
- Damage to soft tissue of the feet
- Joint stiffness in feet and loss of normal toe function
- Callusing and foot ulcers
Signs to look for:
- Diagnosis
- Pain and burning in feet, even at rest
- Callusing
- Reddened areas on foot or open sores on foot
Possible Causes:
- Genetic component
- Viral infection may be causative in creating some cases of diabetes
- Failures of dietary and weight management issues an create Type II diabetes
Goals:
- Medical treatment and control of blood sugar levels
- Reduce pressures on the foot
- Protect feet against infection
- Support arch
- Footwear that protects and footwear for regular exercising
How We Help:
Arch Supports:
- BioOrthotics exercising support with metatarsal lift
- Lower and thinner arch support with longitudinal and metatarsal support for use when shoes cannot accommodate the BioOrthotics exercising support
- Plastazote insole if more cushioning needed
Shoes:
- Extra depth, double or triple depth shoe with high toe box, firm heel counter, rocker sole and connecting shank
- Smart footwear such as stable heel to toe rockers, negative heel shoes or shoes with titanium springs
- Avoid flip-flops. Only wear sandals with a back and only the Orthaheel, Alegria or Aetrex brand
- Wear heels and pumps minimally and go barefoot only minimally
Other:
- Copper, bamboo or silver non-binding socks that wick moisture away from the foot
- Place cedar shoe trees in shoes after each wearing so shoes always fully dry out
Activities:
- Regular exercise program that promotes increased strength and circulation in lower extremities
- Rotation of weight bearing and non-weight bearing exercising, such as walking (weight bearing) and swimming or bicycling (non-weight bearing)
- Regular callus filing with pumice device (leaving cutting of calluses to a physician only)
- Regular skin care program to include exfoliating and moisturizing, however do not put moisturizer between toes
