Every diabetic in the world is warned by their doctor to take care of their feet, that their feet can quickly get infected and cause major problems later. But many diabetics are not aware of the kind of problems their feet can encounter. Here’s shedding a little light on the subject.
How to identify problems in the diabetic foot Be alert on the signs of any change in the skin’s texture and appearance. Skin discolouration is often the first sign of an infected diabetic foot, and it signifies poor blood circulation, an ulcer or a lump of scar tissue inside the foot. The discoloured skin is pale at first, before progressing to a greenish shade. At this stage, it might not have much sensation as well. If there has been no recent injury to cause the discolouration, it means that there is an internal infection. Show a doctor the discolouration if the skin turns black in colour, or if there is a tingling sensation in the toes, or if the feet are numb. All these signs together mean that first stage gangrene has set in, and it must be arrested before it captures the entire foot. Gangrene is common among diabetics, and if it spreads, the foot might need an amputation. Tingly feet are also a sign of first stage nerve damage. If allowed to progress, the feet become completely numb and cannot feel cuts or bruises, which makes them vulnerable to further injury and infection. Another sign of diabetic foot is thickened skin on the sole, and also blisters under the toes. The skin thickens as a result of reduced moisture and poor blood circulation, a common sign in those with high blood sugar. How to care for feet when you have diabetes
