Diabetes can impact the peripheral nerves in the feet, leading to potential damage and disrupting blood circulation in the lower limbs and feet. Additionally, the compromised immune system associated with diabetes makes individuals more vulnerable to infections caused by bacteria or viruses. 

One complication of diabetes, known as Diabetic Peripheral Neuropathy, gradually dulls sensation in the soles of the feet. As symptoms worsen, it can lead to foot ulcers and, in severe cases, foot amputation, making it a potentially fatal condition. 

Regular check-ups at a foot clinic allow individuals with diabetes to prevent and detect issues related to blood circulation and nerve function early on. Through these routine examinations, individuals can receive timely and appropriate treatment to manage diabetes-related complications.
