Diabetic Foot Among Diabetic Patients
Subject: Medical | Topics:


It is estimated that approximately 15% of the more than 150 million people with diabetes world-wide will at some stage develop diabetic foot ulceration. Diabetes mellitus is a chronic disease caused either by a deficiency in the production of insulin by the pancreas, or by the inability of the body to utilize the insulin produced. The condition needs constant monitoring to be kept in check and is linked to a number of serious complications such as vascular disease, retinopathy, diabetic nephropathy and diabetic foot ulcers. (Conva Tec USA, n.d,)

Diabetic foot is often quite a dreaded disability, with long stretches of hospitalization, and impossible, mounting expenses, with the ever dangling end result of an amputated limb. The phantom limb plays its own cruel joke on the already demoralized psyche. The diabetic foot, no wonder, is one of the most feared complications of diabetes. Diabetic foot is characterized by a classical triad of neuropathy, ischemia, and infection. Preventing the diabetic foot should be the first priority. This can be achieved by identifying the high-risk individuals, like those with peripheral neuropathy, peripheral vascular disease, foot deformities, and presence of callus.        ( Pendsey, 2010, p.75-79).

The prevalence of foot ulceration among patients with diabetes mellitus ranges from 1.3% to 4.8% in the community, to as high as 12% in hospital. This represents considerable patient morbidity, and is associated with substantial health-care costs. The pathophysiology of diabetic foot ulceration is multifactorial, but peripheral neuropathy is thought to be responsible for most cases. To prevent foot ulceration and amputation, clinical guidelines recommend early identification of risk, based on annual foot screening of all diabetic patients, with targeting of preventive and treatment interventions to ‘high risk’ individuals. Key to this preventive strategy is a structured clinical assessment that incorporates diagnostic tests alongside a thorough history and examination. (Predicting foot ulcers in patients with diabetes: a systematic review and meta-analysis,2007, p. 65-86).

Diabetic patients who have poor glycemic control may suffer from foot ulceration. This complication has become more prevalent since advances in the general medical care of diabetes particularly the discovery of insulin has prolonged the life expectancy of patients with this disease. A study revealed that 3% of total hospital admissions were of diabetic foot. (Haroun,  Shukr,  Choudhry, & Hussain, 2009,)

Treatment of diabetic foot ulceration is much more complex than simply putting a dressing over a wound. Diabetic foot ulceration is a significant cause of morbidity and is the most common reason for hospital admission in diabetic patients. Annually, two to three percent of diabetic patients1,2 will develop foot ulcers, and up to 15 percent of diabetic patients will develop chronic ulcers during their lifetimes. In those who require lower-limb amputation, 70 to 90 percent will be preceded by a foot ulceration. (Dinh,  Pham, Veves, n.d.)

There is currently little consistency in the education provided to people with diabetes regarding foot health and foot self-care. Of particular concern are those patients who are considered to be at low risk of developing diabetes-related foot complications. These patients may receive little, if any, information about these complications and how they might be avoided .There is little specific evidence-based guidance regarding the content or provision of foot care advice for diabetes patients without established (overt symptoms of) neuropathy or peripheral vascular disease . Indeed, only two specific guidelines currently exist for this patient population—those published by the American Diabetes Association and the International Working Group on the Diabetic Foot in 2004 and 2007, respectively. (McInnes, et al.2011, p. 162-167)

Diabetes mellitus (DM) is a metabolic disorder that is characterized by chronic hyperglycaemia; it is a common and potentially disabling chronic disease. The condition is presently afflicting 194 million people worldwide and is estimated to rapidly increase to 333 million people in 2025 as a consequence of longer life expectancy, sedentary lifestyle and changing dietary patterns. This rise in prevalence of DM is likely to bring a concomitant increase in its complications among diabetic patients. One important complication of DM are the foot problems; these complications constitute an increasing public health problem and are a leading cause of admission, amputation and mortality in diabetic patient. In addition to causing pain and morbidity, foot lesions in diabetic patients also have substantial economic consequences, beside the direct costs of foot complications, there are also indirect costs relating to loss of productivity, individual patients’ and family costs and loss of health related quality of life. The lifetime risk of a person with diabetes developing a foot ulcer could be as high as 25%, and it is believed that every 30 seconds a lower limb is lost somewhere in the world as a consequence of diabetes.( Desalu, Salawu,  Jimoh,   Adekoya,   Busari, Olokoba,2011p. 60-65)

Diabetes is reaching epidemic proportions and with it carries the increased risk of complications. Disease of the foot is among one of the most feared complications of diabetes. The term ‘Diabetic Foot’ consists of a mix of pathologies including diabetic neuropathy, peripheral vascular disease, Charcot’s neuroarthropathy, foot ulceration, osteomyelitis and the potentially preventable endpoint, limb amputation. The lifetime risk of a person with diabetes developing foot ulceration is reported to be as high as 25%. (The diabetic foot,2008, p. 685-695)

DF is the main cause of nontraumatic lower extremity amputations and precedes 85% of the cases. DF lesions are a significant health and socioeconomic problems, having adverse effects on the quality of life and imposing a heavy economic burden on the patient and the State; it can lead to prolonged hospitalization and the need for rehabilitative and home care services. The development of a foot ulcer is traditionally considered to result from a combination of peripheral vascular disease, peripheral neuropathy and infection. More recently, some factors have been identified that are believed to increase the risk of amputation in these patients. Early recognition and management of risk factors for foot complications may prevent amputations, especially of the major type and prevent other adverse outcomes. (Shojaiefard ,  Larija, 2008, p. 32-37)


This study will be help to findout: The overall prevalence of diabetic foot among diabetic patients. The risk factors associated with diabetic foot such as socio-economic factors, medical factors and psychological factors. Minimize the risk factor of diabetic foot with its complication in diabetic patients. The economic burden associated with diabetic foot is preventable in many cases. To knowledge buildup including patient education, foot care, and the use of appropriate footwear ,may be cost effective or even cost saving if applied to patients with risk factors for foot ulcers. Treatment seeking behaviors with diabetic patients. Find out the level of dependency with diabetic foot and build up the rehabilitation program to minimized dependency as well as improved functional activity. Seventy-one percent of the amputations were precipitated by a foot ulcer. The purpose of this study to evaluate the change in diabetes-related lower extremity amputations as well as the recurrence of foot ulcers. Diabetic foot problem are indeed a global problem and there is no area in the world that does not report the development of foot lesions as a consequence mainly of neuropathy and vascular disease with in the diabetic patients. This study will also help to find out the severity and prognosis of diabetic foot among diabetic patients. The database will also help in term of health care priority planning and financial allocation; assess the effectiveness of diabetic treatment, enable us to compare our treatment outcome with the rest of the world, and also as a tool in diabetes awareness and health education programmed. Clearly we have a long way to go in reaching our targets with our diabetic foot care in Bangladesh. Not at least, we also need convincing data to demonstrate the lack of awareness and proper care in particular and its burden within in this country. This study will also help to support our policy and clinical decision-making in improving access to treatment and in improving the provision and delivery of diabetic foot services in Bangladesh.


Nerve damage (neuropathy)

Elevated blood glucose levels over time can damage the nerves of the foot, decreasing a person’s ability to notice pain and pressure. Without these sensations, it is easy to develop callused pressure spots and accidentally injure the skin, soft tissue, bones, and joints. Over time, bone and joint damage can dramatically alter the shape of the foot. Nerve damage, also called neuropathy, can also weaken certain foot muscles, further contributing to foot deformities. (McCulloch ,n.d).

Vascular disease

Peripheral arterial disease (PAD) is a contributing factor to the development of foot ulcers in up to 50% of cases. It commonly affects the tibial and peroneal arteries of the calf. Endothelial cell dysfunction and smooth cell abnormalities develop in peripheral arteries as a consequence of the persistent hyperglycemic state.There is a resultant decrease in endothelium-derived vasodilators leading to constriction. There is also the potential for alterations in the vascular extracellular matrix leading to stenosis of the arterial lumen. Cumulatively, this leads to occlusive arterial disease that results in ischemia in the lower extremity and an increased risk of ulceration in diabetic patients. (Clayton Jr, Elasy,2009 ,p. 52-58)

Poor circulation

Longstanding high blood sugar can damage blood vessels, decreasing blood flow to the foot. This poor circulation can weaken the skin, contribute to the formation of ulcers, and impair wound healing. Some bacteria and fungi thrive on high levels of sugar in the bloodstream, and bacterial and fungal infections can break down the skin and complicate ulcers. (McCulloch, n.d)

Poorly fitting or inappropriate foot wear

Inappropriate shoes increase the risk of callous and ulcer formation, as well as increasing the risk of falls.( Burns,  Leese,  McMurdo,2002, p. 344-346)

Foot deformity

Deformity of the feet is a risk factor because shoes are not designed to fit deformed feet. A prominent bone could thus rub in shoes and cause a sore or wound. If there is loss of feeling as well as deformity the risk is even greater because the person may not feel the shoe rubbing. Deformity may be as obvious as a prominent bone or a crooked toe; however, it could also be subtle like a thick toenail or a callus. Regardless, if possible deformities should either be addressed with properly fitted shoes or even fixed with an operation. (The diabetic foot – Introduction,n.d)

Callus on the sole of the foot has been found to be highly predictive of subsequent ulcer formation among people with diabetes. It is generally accepted that such a callus is secondary to altered loading of the metatarsal heads seen in people with diabetic peripheral neuropathy, and possibly also as a consequence of soft tissue glycation. Such calluses could be plantar warts caused by human papillomavirus. Here, the authors report a case of diabetic foot ulceration in association with verruca.(Griffiths, Fish,  Andrews,2012, p. 84-86)

Increased duration of diabetes

 The longer the patient has had diabetes, the more likely they have developed one or more major risk factors for diabetic lower extremity problems.( Ferry Jr,n.d).

Poor knowledge of diabetes

Good foot care begins with a solid understanding of the processes that can cause foot injury. For diabetics, uncontrolled glucose in the blood stream can eventually begin to damage the blood vessels that nourish the nerves in the legs and feet. Over time, the nerves themselves can become damaged, leading to sensations of burning, tingling, numbness or pain that typically start in the toes. If corrective action is not taken, all feeling in the feet can be lost. Without proper sensory information, it is possible to injure your feet without being aware of the fact. Add to this situation diminished circulation and lack of proper blood

flow, and you have a perfect recipe for serious infection and permanent disability. In the most advanced cases, the process ends in the development of gangrene and the need for amputation.(Gideon Hoyle,n.d)

Psychological factors

Psychological factors influencing adherence behaviours, emotional status and quality of life in diabetic patients at high risk of developing foot ulcers.( Vileikyte,Rubin, & Leventhal,2004).


 If you smoke any form of tobacco, quitting can be one of the best things you can do to prevent problems with your feet. Smoking accelerates damage to blood vessels, especially small blood vessels leading to poor circulation, which is a major risk factor for foot infections and ultimately amputations. (Ferry Jr, n.d)

Sedentary Lifestyle

A lack of daily physical activity can lead to obesity, a major factor in developing type 2 diabetes. Persons with type 2 diabetes are at increased risk for heart disease, stroke, kidney disease, eye complications, and foot and skin problems. (Hicks,2008)


An obese person is anyone carrying over 20% beyond healthy weight for age and height. For diabetics, this can cause diabetic nerve damage, meaning a sprain or minor stress fracture simply does not hurt. Not so well known may be the increase in severe diabetic foot problems, sometimes leading to amputation of an entire leg. (Pritchett, 2010)


1. What will be the prevalence of diabetic foot among diabetic patients?


 Foot complications are common in diabetic patients and are considered one of the most expensive diabetes mellitus (DM) complications to treat. The study was part of a general cross-sectional survey carried out to assess the prevalence and risk factors for foot complications among diabetic patients in Al-Ain district, United Arab Emirates (UAE). A sample of 513 diabetic patients with a mean age of 53 years (SD: ± 13) were randomly selected during 2003/2004. All completed an interviewer-administered questionnaire and underwent medical assessment including foot examination and assessment of presence of peripheral neuropathy (PN) and peripheral vascular disease (PVD).Forty nine percent of the study populations were diagnosed to have DM without presenting with symptoms of diabetes and 35% had hypertension. The majority (86%) had type 2 DM. Of the total sample, 39% (95% CI: 35.1-43.7%) had PN and 12% (95% CI: 8.8–14.4%) had PVD. There were no cases of amputation and only one case had previous history of lower extremity ulceration. Significant risk factors for PN and PVD were: male gender, poor level of education, UAE nationality, increased duration of diabetes, type 2 DM, presence of hypertension and microalbuminuria (MA). (Al-Maskari, El-Sadig, 2007)

The study subjects were selected from the foot clinic of the M.ViswanathanHospital for diabetes, which is a large referral center for diabetes in southern India. Patients of different socioeconomic status visit the hospital. In this project 2,642 patients (1,751 men and 891 women) with a high-risk foot were selected according to criteria of the International Consensus on the Diabetic Foot. The study subjects were divided as urban, patients staying in cities and bigger towns (n = 1,377), and rural, patients staying in the villages away from main town or city (n = 1,265).  Intergroup differences were absent in the duration of diabetes and the prevalence of peripheral vascular disease. The mean age of the urban sample was higher than that of the rural sample (P = 0.01). Prevalence of foot infection was higher among rural than urban patients (26 vs. 34%, P = 0.0001). Amputation rates were also higher among rural than urban patients (3 vs. 8%, P < 0.05). Recurrence of foot infection was higher among rural than urban patients (8 vs. 13%, P = 0.003). Surgical intervention was also more frequent among rural than urban patients (6 vs.10%, P = 0.04). (Viswanathan, Madhavan, Rajasekar, Snehalatha& Ambady, 2006 p. 701-703)

A cross sectional study was conducted during the period from June 2009 till January 2010 in a primary care clinic at King Khalid University hospital, Riyadh, Saudi Arabia.The study showed that the prevalence of diabetic foot among 224 diabetic patients attending a primary care clinic, was 6.2%, and 1.3% of diabetic patients had amputated foot. About half of the diabetic patients were 60 years and above. Most of the patients (69.7%) were on oral hypoglycemic agents, and 28.1% were on insulin. Only 31.7% had HBA1C less than 7, 33% followed their blood sugar levels regularly at home by gluco meter, and only 30.8% of diabetic patients examined their feet regularly at home. (Al Turki,2010 p. 18-23)

In this U.K. population-based study, we screened 15,692 type 1 and type 2 diabetic patients in the community health care setting for foot ulcers, foot deformities, neuropathy, and PAD plus other characteristics. In total, 13,409 were European (85.5%), 1,866 were South Asian (11.9%), and 371 were African Caribbean (2.4%). The age-adjusted prevalence of diabetic foot ulcers (past or present) for Europeans, South Asians, and African Caribbeans was 5.5, 1.8, and 2.7%, respectively (P < 0.0001). Asians and African Caribbeans had less neuropathy, PAD, and foot deformities than Europeans (P = 0.003). The unadjusted risk of ulcer (odds ratio [OR]) for Asians versus Europeans was 0.29 (95% CI 0.20-0.41) (P < 0.0001). PAD, neuropathy, foot deformities, and insulin use attenuated the age-adjusted OR from 0.32 to 0.52 (0.35-0.76) (P < 0.0001). African-Caribbean versus European ulcer risk in males was attenuated from 0.60 to 0.71 by vibration sensation. (Vileikyte., Rubin.,  Leventhal.,2004)

The effect of ethnicity on diabetic foot ulceration (DFU), neuopathy and peripheral arterial disease (PAD) remains controversial, with few previous studies from Egypt. The prevalence of DFU and its risk factors in a cohort of patients presented to  the outpatient diabetes clinic at MansouraUniversitySpecializedMedicalHospital. Over a period of 12 months, 1220 diabetic patients were screened for DFU, neuropathy, PAD, foot deformities, and skin and nail abnormalities. The mean age was 50.5 ± 10.9 years and 36.8% were male. Diabetes duration was 7.9 ± 5.9 years and BMI 34.5 ± 6.7. The prevalence of active or past foot ulceration was 1.2% and 5.7% respectively. Monofilament insensitivity was found in 124 patients (10.2%). Only 38 patients (3.1%) had absent foot pulses. We found dry skin in 544 patients (44.6%), calluses in 69 (5.7%), tinea pedis in 532 (43.6%) and thick nails in 215 (17.6%); 61.6% of our patients used inappropriate footwear and 93.8% received no prior foot education. (El-Nahas, Gawish,Tarshoby,  State&Boulton,2008 p. 362–366)

To survey diabetic foot problems in the Taiwanese population, a total of 16,994 non type 1 diabetic patients were randomly selected for telephone interview from a group covered by the National Health Insurance (>96% of the total population is covered by this health care system). They were questioned on whether they had diabetic foot problems, as indicated by ulcer, gangrene, or amputation on the lower extremities. Lifetime prevalence was calculated, and various risk factors were analyzed. A total of 12,531 case subjects (response rate 73.7%) were successfully interviewed. Diabetic foot problems were present in 369 patients (prevalence 2.9%) with 540 initiating events. Ulcers represented 86.7% of all initiating events. Approximately 26.9% of the ulcers  progressed to gangrene or amputation, and ulcers preceded 71.9% of all amputations.(Tseng, 2003, p. 335 )

A cross-sectional study was conducted for male diabetics in the Aseer region, KSA, during the first quarter of the year 2004.A questionnaire and physical examination of the foot were used to assess their behaviors towards foot care. All the male diabetic patients (107) who attended during the study period were assessed. Mean age was 58 years, mean duration of DM was 10 years. Good diabetic control was 24%, 37% did not know the negative effect of DM on the feet,9-22% had different symptoms of diabetic foot ,53% checked their feet regularly ,31% had fungal infection while an absence of pulse was detected in 7%.( Al-Khaldi, 2008, p. 103-106)
