Ulcers on legs due to diabetes

Leg ulcers due to diabetes, also known as diabetic foot ulcers, are a common complication of diabetes mellitus, particularly in individuals with poorly controlled blood sugar levels. These ulcers typically develop on the feet or lower legs and can be challenging to manage due to impaired wound healing and compromised circulation associated with diabetes.


  1. Neuropathy: Diabetes can cause nerve damage (neuropathy), leading to loss of sensation in the feet and legs. This can result in injuries or trauma going unnoticed, allowing ulcers to develop and worsen without prompt treatment.
  2. Peripheral Arterial Disease (PAD): Diabetes increases the risk of peripheral arterial disease, which reduces blood flow to the legs and feet. Poor circulation impairs the body's ability to deliver oxygen and nutrients to the affected tissues, hindering wound healing and increasing the risk of infection.
  3. Foot Deformities: Diabetes can cause structural changes to the feet, such as hammertoes, bunions, or Charcot foot, which can create pressure points and friction that contribute to ulcer formation.
  4. Poor Immune Function: Diabetes weakens the immune system, making individuals more susceptible to infections. Once an ulcer develops, the body's ability to fight off bacteria and pathogens is compromised, leading to delayed healing and potential complications.


  1. Persistent redness, swelling, or warmth in the affected area
  2. Open sores or wounds that may be painful or non-painful due to neuropathy
  3. Drainage or pus from the ulcer
  4. Foul odor
  5. Blackened or hardened skin around the ulcer
  6. Signs of infection, such as fever or chills


  1. Wound Care: Proper wound care is essential for diabetic foot ulcers. This includes keeping the ulcer clean and dressed, debridement (removal of dead tissue), and offloading pressure from the affected area to promote healing.
  2. Infection Management: If the ulcer becomes infected, antibiotics may be necessary to treat the infection and prevent it from spreading.
  3. Blood Sugar Control: Tight control of blood sugar levels through medication, diet, and lifestyle modifications is crucial for optimizing wound healing and preventing further complications.
  4. Offloading: Offloading pressure from the ulcerated area with the use of specialized footwear, orthotic devices, or casts can help alleviate pressure and promote healing.
  5. Vascular Assessment: Evaluation of blood flow to the legs and feet is important to identify and address any underlying peripheral arterial disease that may be impairing wound healing.
  6. Multidisciplinary Care: Diabetic foot ulcers often require a multidisciplinary approach involving podiatrists, wound care specialists, endocrinologists, vascular surgeons, and infectious disease specialists to provide comprehensive care and prevent recurrence.

Preventing diabetic foot ulcers is crucial, and individuals with diabetes should inspect their feet daily, wear proper footwear, maintain good foot hygiene, and seek prompt medical attention for any signs of injury or skin breakdown. Early intervention and comprehensive care can help prevent complications and improve outcomes for individuals with diabetic foot ulcers.
