Diabetes-related foot disease (DFD) describes complications of diabetes that affect the feet (Cleveland Clinic 2024).
High or fluctuating blood glucose levels caused by diabetes decrease blood flow to the extremities, and nerve damage will prevent the skin from repairing itself. The nerve damage caused by hyperglycaemia is known as diabetic neuropathy (Cleveland Clinic 2021).
DFD results in an insensitive and potentially deformed foot, sometimes causing an unusual manner of walking (DFA 2022).
DFD can occur in patients with both Type 1 and 2 diabetes (Packer et al. 2023).
Diabetic neuropathy can cause any skin, nerve or circulation issue in the feet to become infected or lead to complications. Conditions that could lead to complications include:
(Cleveland Clinic 2024)
Due to the loss of sensation caused by diabetic neuropathy, a person is unlikely to notice if they have injured their foot and, furthermore, are unlikely to realise that their condition is worsening (Cleveland Clinic 2024).
The foot sores, cuts and ulcers incurred by the patient may become infected. These infections can potentially spread to the bone, and ulcers can lead to tissue death (Mayo Clinic 2022).
As a result of this, the amputation of a toe, foot or even the lower leg may be necessary (Mayo Clinic 2022).
Around 1,300,000 (1 in 20) Australians have diabetes (ABS 2022). Diabetes presents a considerable challenge to Australia’s healthcare system and is one of the fastest-growing chronic conditions in the country (Diabetes Australia 2024).
Over 4,400 amputations related to diabetes are performed every year in Australia, yet it’s believed that 85% of these amputations are avoidable if detected early and managed properly (Diabetes Australia 2023a)
The solution most often suggested to patients is a daily foot care routine and regular foot monitoring with the help of a healthcare professional (Diabetes Australia 2023b).
In the majority of cases, foot ulcers will heal if the correct procedures are followed.
It’s worth noting that even the best wound care cannot compensate for ongoing damage to the wound bed, inadequately treated ischaemia or infection. Patients with a deep ulcer often require intensive treatment or may need to be admitted to the hospital (DFA 2022).
The following treatment strategies are recommended:
(DFA 2022)
Patients should seek immediate medical attention if they notice any of the following signs:
(Diabetes Australia 2023b)
Prompt medical attention (not necessarily immediately but still within a week’s time frame) is to be advised if patients notice:
(Diabetes Australia 2023b)
The following preventative measures are recommended to avoid the escalation of this condition:
(DFA 2022; Diabetes Australia 2023b; Better Health Channel 2023)
A study conducted by the University of Wollongong in 2018 found that people with DFD ulcers tended to have an overall low quality of life, especially those with larger ulcers, chronic ulcers and ulcers complicated by infection (Khunkaew et al. 2019).
Researchers collected data from 12 studies on health-related quality of life in people with DFD and found that patients had poorer physical functioning, vitality and overall quality of life than those without DFD (Khunkaew et al. 2019).
The severity of DFD should not be underestimated. As the prevalence of diabetes continues, DFD will remain a prominent health issue.
Diabetes-related foot ulcers are globally recognised as the primary cause of diabetes-related hospitalisations and amputation, with mortality rates comparable to those of many cancers (DFA 2022).
Education and prevention are vital to improving the quality of life in people with diabetes and to curbing high rates of avoidable amputations.
