It is rather alarming to learn that a limb is amputated every 30 seconds on average due to a diabetic foot infection. According to a study, patients with diabetes account for 40 to 60 percent of all lower limb amputations.

More than 85% of these amputations are caused by foot ulcers that progress to gangrene or severe infection. An estimated 3-8% of people have diabetic foot ulcers. To prevent such complications, aggressive management and education of the patients and caregivers are of utmost importance.

In this blog, we will discuss the predisposing risk factors for foot infection in patients with diabetes and measures to prevent its complications.

What Causes Diabetic Foot Ulcers?

Let's start with the basics and figure out what happens to the body in diabetes. When blood sugar levels are out of control, it can cause damage to the blood vessels and the nerves, resulting in poor blood circulation. Inadequate blood supply to the foot increases the chances of foot ulcers in case of foot care neglect.

These ulcers either never heal or take an exceptionally long time to heal, leading to the inevitable onset of an infection. Infections of the soft tissue or bone below is referred to as diabetic foot ulcer.  These typically necessitate hospitalization and may even lead to limp amputation.

Damage to blood vessels is a direct result of uncontrolled diabetes. When blood sugar levels are consistently high, they cause damage to the blood vessels in the foot, which reduces blood flow. In the absence of treatment, the affected areas (often the feet) become numb, painful, and lose their sense of feeling.

Did You Know?

Approximately 15% of people with diabetes develop foot ulcers, which are open sores or wounds, most often on the soles of their feet.

What Are the Common Signs of Diabetic Foot?

In the event that you have diabetes, you should always be on the lookout for signs such as

  • Leg cramps
  • Swelling
  • Burning sensation
  • Itching
  • Skin discolouration
  • Redness
  • Sharp pain

In case, you develop a diabetic foot infection, chances are you will also develop the following: 

  • Sepsis: Is bloodstream infection which damages tissues and organs. The common symptom is the skin turning blue.
  • Gangrene: It's caused due to a lack of blood flow or a bacterial infection.
  • Skin Infections: Diabetic foot ulcers can develop skin infections, causing swelling, foul-smelling discharge, fever, and chills.
  • Abscess Formation:  It is the formation of painful pus under the surface of the skin

7 Tips To Prevent Diabetic Foot Infection

Yes, diabetics can prevent diabetic neuropathy (diabetic foot infection) with some lifestyle changes like

1. Maintain Proper Foot Hygiene

Wash them every day with a bar of mild soap and warm water.

2. Control Blood Sugar Levels

 Make sure your blood sugar level is under control by taking care of your dietary intake.

3. Check Your Feet

Regularly check your feet for new cuts, scrapes, or wounds.

4. Wear Diabetic Footwear

Wear comfortable shoes that fit well and keep your feet safe. And as always, never walk barefoot. 

5. Stay Active 

Ensure good blood flow to the feet by walking or running every day.

6. Stop Smoking

Cut down on habits like smoking which acts as contributing factor to restricting blood circulation.

7. Watch Out for Ulcers

Do not take care of foot ulcers by yourself! See your diabetologist or a podiatrist right away.

Did You Know?

75% of foot ulcers are preventable!

When Is the Foot Amputated?

Many patients who have diabetes also have peripheral artery disease (PAD), which restricts blood flow to the feet. PAD and diabetic neuropathy, when combined, make it much easier to develop ulcers and infections in the foot.

With time, the risk of foot infection spreading throughout the bloodstream increases. In such a scenario, amputating the damaged foot might be the only way to prevent this from taking place.

Did You Know?

Diabetic foot ulcers and amputations are 2X as lethal for men as they are for women.

Is There a Way to Diagnose Diabetic Neuropathy?

There are several diagnostic tests that can evaluate a diabetic foot: 

  1. X-Ray

It can give doctors a complete picture of the skeletal structure of the foot.

  1. Ultrasound or Magnetic Resonance Imaging (MRI) 

Provides an apparent view of the foot's soft tissues.

  1. Filament Tests

It is the most accurate way to gauge how sensitive a person's feet are to touch.

  1. Nerve Condition Tests

The test evaluates how well electrical signals can be transmitted through the lower extremities.

  1. Electromyography (EMG) Tests

It analyzes electrically the impulses sent out by the foot's muscles.

Final Note

Making simple modifications to your lifestyle can bring noticeable differences to your quality of life. With a clear picture of how an increase in blood sugar levels can complicate foot infections, you are sure to book a diagnostic test right away.
