Diabetic foot, also referred to in our specialty as diabetic foot syndrome, mainly occurs in long-standing cases of diabetes, where the lower limbs develop arterial atherosclerosis and neuropathy, leading to ulcers in the feet. Severe diabetic foot can result from significant neuropathy, such as extreme numbness and pain in the lower limbs, pain akin to being pricked with needles, and severe vascular disease, such as ischemia in the lower limbs. Patients may feel unusually cold even in winter and sometimes need to wear socks even on hot days due to extreme sensitivity to cold, indicating severe vascular disease. Such serious vascular and neuropathic conditions represent a high-risk foot, which has a high likelihood of developing ulcers. The early signs of potential ulceration include these typical symptoms along with local injuries, such as nail trimming or other external injuries, which can easily trigger these conditions. Therefore, it is crucial to be vigilant and avoid these precipitating factors.
