how does diabetes cause you to lose limbs

Diabetes can result in limb loss due to the chronic damage caused by high blood glucose levels to the circulatory and nervous systems.

Initially, diabetes induces vascular changes that can lead to narrowing or blockage of blood vessels, reducing blood flow to the extremities. Insufficient blood supply deprives tissues of necessary oxygen and nutrients, potentially causing damage or necrosis. Additionally, diabetic neuropathy diminishes a patient's sensitivity to pain, temperature, and other sensations, which can delay the detection and treatment of minor wounds or infections, allowing them to progress into severe ulcers or infections. Furthermore, individuals with diabetes are more susceptible to foot deformities such as claw toes or flat feet, which increase skin pressure points and heighten the risk of ulcers. In extreme cases, if an infection is severe and uncontrollable, or if there is extensive tissue necrosis, amputation may be required to prevent further deterioration of the condition.

Hence, for individuals with diabetes, it is vital to regularly monitor blood glucose levels, maintain good glycemic control, conduct routine foot examinations, and adhere to medical advice. Immediate medical attention should be sought for any foot issues to prevent potential serious complications.
