A sudden change in foot color, an unexplained drop in skin temperature, or a wound that simply will not heal can signal something far more serious than a minor injury. Gangrene is a medical emergency that develops when blood flow to tissue is cut off or when a severe infection takes hold, and it most often strikes the feet of people living with diabetes or circulation problems.
At Sweeney Foot & Ankle Specialists, Dr. D. Sean Sweeney, DPM, FACFAS, and Dr. Christy Leahey, DPM, FACFAS, bring more than 20 years of trusted experience treating advanced foot and ankle conditions across Greater Houston. Voted Best Podiatrist in The Woodlands by Living Magazine every year since 2012, our team combines compassionate, patient-centered care with advanced medical and surgical solutions for the most urgent situations.
What Is Gangrene?
Gangrene refers to the death of body tissue, usually triggered by a loss of blood supply or a serious bacterial infection. While anyone with poor circulation can be affected, the most common form develops in the feet and toes of people with diabetes who also experience reduced blood flow in the lower extremities.
Because diabetic neuropathy can dull the body’s natural warning signals, a small problem such as an ingrown toenail, blister, or minor cut may go unnoticed. Without pain to alert you, the wound can quickly become infected and, paired with poor circulation, progress into gangrene.
Warning Signs to Watch For
- Sudden pain in the feet or legs
- Skin that feels cold to the touch
- Color changes such as pale, blue, purple, or black skin
- Non-healing sores, ulcers, or open wounds
- Redness, swelling, fever, or weakness around an injury
- A foul-smelling discharge from a wound
These symptoms point to a sudden blockage of blood flow or a rapidly spreading infection and require immediate medical attention.
Severe Infections and Gangrene
Some forms of gangrene are caused by aggressive bacteria, including Hemolytic Streptococcus, often referred to as flesh-eating bacteria. These infections can begin from a small abrasion and spread quickly, producing intense local heat, redness, swelling, fever, and weakness. Without prompt treatment, the condition can lead to amputation or become life-threatening.
Treatment Options
Treatment depends on the cause, severity, and the patient’s overall circulation and health. Our team will evaluate the affected tissue, assess blood flow, and create a personalized plan that may include:
- Surgical removal of dead or infected tissue (debridement)
- Bypass surgery or vascular referral to restore circulation
- IV antibiotics to control infection
- Hyperbaric oxygen therapy referrals to encourage tissue healing
- Comprehensive wound care and ongoing monitoring
- Supportive diabetic foot management to prevent recurrence
