Vascular surgeon warns about high risks of leg gangrene in monsoon: 5 warning signs, symptoms, prevention tips

People with undiagnosed diabetes are at risk of getting leg gangrene, more so during the monsoon season.

Monsoon weather paves the way for many worrying health concerns. The unpredictable climate also aggravates existing conditions. And with people still commuting to work and going about their day regardless of the torrential rains and overcast skies, it becomes all the more important to stay alert. One such condition is leg gangrene.

Dr Ashank Bansal, who is a vascular surgeon and interventional radiologist at Surana Sethia Hospital, Chembur, shared with us that the highest risk factors include undiagnosed diabetes, poor hygiene and monsoon's high humidity. Monsoon especially has the environment for infections to grow, particularly for diabetic people.

Leg gangrene is a threatening condition as it may even require amputation. Dr Bansal described leg gangrene, “Leg gangrene is the death of body tissue due to a lack of blood flow or a serious bacterial infection. It most often affects the toes, feet, and legs. The moist, dirty conditions during the monsoon can increase the risk of skin damage and infections. So, if untreated, it may even require amputation."

Dr Bansal shared a guide, listing out the top risk factors, complications, symptoms and prevention tips:
