Charcot Foot: A Lesser-Known but Serious Condition That Affects People with Diabetes

Charcot Foot

Charcot foot is a rare but serious complication of diabetes that affects the bones and joints in the foot. 

People with diabetes may develop other complications. One of the potential complications is Charcot foot. This condition is named after the French neurologist Jean-Martin Charcot, who first described it in the late 1800s. It is estimated that up to 1% of people with diabetes may develop Charcot foot, which can lead to significant disability and even amputation if left untreated.

Symptoms and Causes of Charcot foot

Charcot foot is caused by nerve damage, a common complication of diabetes. This nerve damage can lead to loss of sensation in the foot, which means that minor injuries or stresses may go unnoticed. This can cause the bones and joints in the foot to break down, leading to deformity and instability.

If this is left untreated, it can lead to serious complications such as foot ulcers, infections, and even amputation. Charcot foot can also cause permanent deformity and instability of the foot, which can make walking and standing difficult.

Foot Ulcers: Charcot foot can cause foot ulcers to develop, which are open sores that can become infected. Foot ulcers can be difficult to treat and can lead to more serious complications such as gangrene.

Infections: Infections are a serious risk for people with Charcot foot, as the breakdown of bone and tissue in the foot can provide a breeding ground for bacteria. Infections can cause further damage to the foot and can even spread to other parts of the body.

Amputation: In severe cases, Charcot foot can lead to amputation of the foot or even the leg. Amputation is a last resort and is only recommended if other treatments have failed or if there is a risk of serious infection.

Diagnosis and Treatment

Diagnosis of Charcot foot can be challenging, as the symptoms can be similar to other foot conditions such as gout or infection. X-rays and other imaging tests are often used to confirm the diagnosis and assess the extent of the damage.

Treatment options typically involves immobilisation of the foot to allow the bones to heal. This may involve wearing a cast or a special boot. In some cases, surgery may be necessary to stabilise the foot and prevent further damage. Pain relief and antibiotics may also be prescribed to manage any pain or infection.


Prevention is key, as the damage caused by this condition can be irreversible. Good foot care is important for people with diabetes to help prevent complications such as this Some ways to prevent Charcot foot include:

  • Maintaining good blood sugar control
  • Checking feet regularly for any signs of injury or infection
  • Wearing comfortable, properly fitting shoes
  • Avoiding high-impact activities that can stress the feet
  • Seeing a podiatrist regularly for foot exams and care


Charcot foot is a serious complication of diabetes that can lead to significant disability and even amputation if left untreated. Early diagnosis and treatment are essential to prevent further damage and ensure the best possible outcome. Good foot care and regular foot checks are important for people with diabetes to help prevent complications such as Charcot foot.
