As the old saying goes, “A journey of a thousand miles begins with the first step”, the importance of the feet is self-explanatory. But the journey of a thousand miles has become a luxury for diabetic patients because there is an invisible killer lurking around their feet, which may take away their feet or even their lives at any time. This invisible killer is the diabetic foot. So is the diabetic foot far away from us? Is it scary? The data tells you the answer. Since the 21st century, diabetes has become the third largest chronic non-communicable epidemic threatening human health. 2017, the International Diabetes Federation (IDF) estimated that 425 million people worldwide have diabetes, and the number of people with diabetes is expected to increase to 700 million in 2045. Back in 2013 the IDF estimated that 5.1 million people died from diabetes worldwide (1 death every 6 seconds). In China, the prevalence of diabetes in adults over the age of 18 is 11.6% and there are currently at least 145 million people with diabetes (1 in 10 people). Diabetic foot is a common complication in the later stages of diabetes, complicating foot ulceration, necrosis, the formation of chronic non-healing wounds and eventually leading to amputation or even death of the patient. In 2015, the IDF stated that between 9.1 million and 26.1 million people worldwide develop a diabetic foot each year, and that these patients have the disease for more than 10 years, with the incidence of diabetic foot increasing as the disease progresses, with the incidence of diabetic foot increasing for patients with 20 years of disease. The chance of developing a diabetic foot increases to 50% for those with 20 years of disease. The New England Journal of Medicine, the top international medical journal, reported that 19%-34% of diabetic patients will develop diabetic foot (2-4 out of 10). 2005 JAMA, the authoritative journal, stated that diabetic foot patients account for 40%-60% of all non-traumatic amputations, and that 20% of these patients who develop foot ulcers that are not treated in time will eventually In 2017, the New England Journal of Medicine reported that the 5-year risk of death in patients with diabetic foot was 2.5 times higher than in diabetic patients without diabetic foot, and the risk of death in patients with diabetic foot was as high as 70% after 5 years of amputation. In China, the incidence of diabetic foot is as high as 30% (1 in 3 diabetic patients develop diabetic foot), the annual recurrence rate is as high as 31.6%, and the mortality rate is as high as 14.4%. In short, diabetic foot is actually not far from us, however, most sugar lovers are far from enough attention to the hazards of diabetic foot, until the attention, has long been brewing bitter fruit. Sugar lovers take active action! Raise awareness, early detection and early treatment.
