Diabetic foot screening is a preventive health assessment aimed at detecting early signs of foot complications related to diabetes. This physical examination includes checking for infections, ulcers, circulation problems, and nerve damage, which can lead to serious complications if left untreated. Early detection and timely intervention are crucial in preventing severe outcomes like amputations.

In Singapore, around 11.3% of the population is affected by diabetes, and diabetic foot-related complications account for 20% of emergency admissions. Individuals with diabetes are 20 times more likely to face amputation than those without diabetes, but regular foot screenings have been shown to reduce this risk.

Diabetic foot ulcers are open sores or wounds that usually form on the legs or the feet. They develop when high blood sugar levels damage nerves and blood vessels, impairing the body’s ability to heal.

Diabetic foot ulcers progress through various stages, from being at risk to developing gangrene. Early noticeable signs typically include:

• Unexplained pain or discomfort in the foot
• Redness, swelling, or warmth in the affected area
• Blisters, calluses, or changes in skin colour
• Open wounds that take a long time to heal, or an unpleasant odour or discharge from the wound

If you have diabetes and notice any of these symptoms, it is vital to seek medical attention immediately.

In addition to diabetes impairing the body’s ability to heal, several factors contribute to the risk of diabetic foot ulcers, including:

• Peripheral Neuropathy: Loss of sensation in the feet, which can prevent you from noticing injuries or pressure points.
• Poor Circulation: Restricted blood flow due to damaged blood vessels, making it harder for wounds to heal.
• Foot Deformities: Changes in foot structure or shape, which increase pressure on certain areas, leading to ulcers.
• Inadequate Foot Care: Failure to maintain proper foot hygiene or wear suitable footwear can also increase the risk of ulcers.

People with diabetes are advised to have diabetic foot screenings at least once a year. However, individuals with higher risk factors may need more frequent screenings, typically every 3 to 6 months. These higher-risk factors include:

• A history of foot ulcers or amputations
• Nerve damage or loss of sensation in the feet
• Poor blood circulation or peripheral artery disease
• Foot deformities such as hammertoes or bunions

It is best to consult your doctor for personalised advice on the appropriate screening frequency.
