Ayurvedic measures can be an effective solution to prevent the foot ulcer from worsening. These medicines aim to control diabetes and keep your blood sugar levels in check so that the foot ulcer does not deteriorate. Some of the best Ayurvedic medicines for diabetes patients are:

  • Basant Kusumakar Ras
  • Haritaki
  • Chandraprabha Vati
  • Madhusam Powder

Surgery for diabetic foot ulcers

In the severe cases of diabetic foot ulcer, vascular surgeries are required. The most widely performed vascular surgery for the purpose is atherectomy followed by balloon angioplasty.

Atherectomy and Balloon Angioplasty

Atherectomy is a surgical procedure that is performed to make the arteries wider. Widening of the arteries facilitates the proper supply of blood, oxygen and nutrients to the wound so that optimal healing can be achieved.In Atherectomy, the doctor uses laser energy or a rotating blade to remove the plaque, calcium and fat layers from the artery. This makes the artery wider and improves blood circulation.Many a time, Atherectomy is followed by another procedure called balloon angioplasty. In Balloon Angioplasty, the doctor inserts a stent in the artery to hold it open. This ensures continuous and proper flow of blood through the artery.
