Smoking with diabetes is a destructive combination for the foot — it doubles all risks and significantly accelerates all complications. Smoking is a major controllable risk factor that can be stopped.
Smoking's Effect on the Diabetic Foot:
- Blood vessel narrowing: Nicotine causes immediate arterial spasm and narrowing — reducing blood flow to the foot even in those without atherosclerosis. In a diabetic patient who already has atherosclerosis — the effect is catastrophic.
- Accelerated atherosclerosis: Smoking destroys arterial lining and accelerates cholesterol and calcium buildup.
- Reduced oxygen: Carbon monoxide from smoke replaces oxygen in the blood — wounds need oxygen to heal.
- Weakened immunity: Smoking impairs immune cell function and increases infection risk.
- Slowed healing: Studies show smokers need 50% more time for ulcer healing.
- Increased amputation risk: Smokers with diabetes have 4-6 times higher amputation risk.
Quitting Smoking:
Even after years of smoking — benefits begin immediately after quitting. Within weeks, circulation improves noticeably.
At BEIT TARIQ Center, we support our patients in quitting and monitor the improvement in their wound healing.
