One can suffer from a number of foot problems like blisters, corns, calluses, warts etc. Among the worst consequences of diabetes is the increased risk of their infection, leading to the formation of ulcers. The high blood glucose level is the causative factor for such ulcers. Utmost care should be taken to prevent such infections, as they may damage your foot to such an extent, that an amputation becomes unavoidable.
There can be two types of Foot Ulcers caused due to diabetes viz. Neuropathic foot ulcers and Neuroischaemic foot ulcers.
Neuropathic Foot Ulcers
They appear on the foot, under the toes in the planar region. They are usually caused by the forces exerted on specific parts of the foot, due to our posture, leading to the formation of callus. Over the time, it may get thicker and develop into penetrating into the tissue present beneath it. This leads to ulceration.
This form of ulceration is usually indicated by a formation of a white macerated patch on the foot that feels moist to touch. If such a patch is detected, you need to pay urgent attention to it otherwise may develop into hematoma or formation of the ulcer beneath the callus.
Thus, if you have diabetes and detect the above-mentioned symptoms, you should consult the doctor immediately and have the callus surgically removed.
Neuroischaemic Foot Ulcers
These are usually encountered on the margins of ones feet. They are caused due to the friction between the foot and the shoes, we wear. They can also be encountered at the tips of your toes or beneath toe nails, especially the ones that are thick. Their development is characterized by the redness of skin in those areas. This red mark then develops into a blister/ulcer.
Both of the above can lead to the loss of a person's toes or the entire foot, unless they are properly treated at the initial stage.
Treatment of Diabetic Foot Ulcers
The treatment involves the reduction of pressure in those areas. Take prescribed medication i.e. antibiotics given to control it. Antibiotics may vary according to the severity of the foot ulcer. Measures that can be taken at home include, replacement of ill-fitting footwear, washing ones feet frequently to keep them clean, use of certain gel or medications etc.
Foot ulcers caused by diabetes can be very severe, preventing them is always better, than trying to cure after developing.
