Because of circulatory problems and nerve damage causing loss of sensation associated with both type 1 and type 2 diabetes, foot care is enormously important.
Foot Ulcers affect as many as 1 out of 10 people with diabetes.
Even small ulcers on the foot can represent a serious risk: they may heal extremely slowly and need rigorous treatment to cure.
Ulcers can develop into serious lower body infections, with the possibility of amputation at an advanced stage.
That said, sensible precautions should help to reduce risk, such as good foot hygiene, avoid walking out doors in bare feet. If you do have foot pain, changes in colour, odour or slow healing wounds, seek medical advice at an early stage. Don't try to deal with corns and hard skin your self.
