While a staggering 1 million lower limbs are lost to diabetes globally each year, a closer look at the numbers reveals both the staggering severity and, crucially, the significant preventability of this devastating complication.
Key Takeaways
- In the United States, diabetes is the leading cause of non-traumatic lower limb amputations, accounting for approximately 60% of all such amputations annually

- In 2019, the age-adjusted amputation rate for people with diabetes in the US was 12.4 per 1,000 persons with diabetes
- The prevalence of peripheral artery disease (PAD) in diabetic patients is 20-50%, increasing amputation risk by 5-fold
- Smoking among diabetics doubles the risk of amputation, with odds ratio of 2.1 compared to non-smokers
- Poor glycemic control (HbA1c >9%) is associated with a 3.5 times higher risk of lower extremity amputation
- Post-amputation, 50% of diabetic patients experience a contralateral amputation within 5 years
- The 5-year mortality rate after major lower limb amputation in diabetics is 50-70%, exceeding many cancers
- Only 40% of diabetic amputees regain independent mobility within 1 year post-surgery
- Multidisciplinary foot care teams reduce amputation rates by 50-85% in high-risk diabetics
- Daily foot inspections and proper footwear reduce ulcer incidence by 45% in diabetics

- Diabetes-related amputations cost the US healthcare system $11 billion annually
- Lifetime costs for a diabetic amputee exceed $500,000, including rehab and prosthetics
Diabetes remains a top driver of amputations, but proactive care can prevent most cases.
