Are All diabetic Patients at Risk for Foot Ulcers ?

This blog discusses the factors leading to foot ulcers, identifies those at high risk, highlights symptoms to watch for, and emphasizes the importance of proper foot care in preventing complications.

What is a diabetic Foot Ulcer?

A diabetic foot ulcer is an open sore or wound that develops on the foot of a diabetes patient. These ulcers often appear on the bottom of the foot or around pressure points. It is a serious complication caused by a combination of nerve damage, poor circulation, and high blood sugar levels. 

This foot ulcer can lead to severe infections or even amputation depending on its severity. To note it can be prevented with good foot care and needed treatment. The treatment varies depending on the causes and their severity.

Understanding diabetic Foot Ulcer:

People with Diabetes undergo nerve damage, eye problems, diabetic nephropathy, foot problems, and skin damage. This chronic condition affects millions of people worldwide, ranging from mild to high complications.

One of the most talked about and concerning complications in Diabetes is the development of diabetic foot ulcers (DFUs), which can lead to severe infections and even amputation if left untreated.  It is always advisable to discuss with a doctor beforehand if you notice any soreness or wound in the foot to avoid serious problems in the future.

If you have diabetes and are concerned about the possibility of developing a foot ulcer, it’s important to know that it is indeed a risk. Not all diabetic patients have the same level of risk for foot ulcers, but diabetes increases the likelihood due to factors such as poor circulation, nerve damage (neuropathy), and slower wound healing. 

Fortunately, diabetic ulcers can be prevented with proper foot care and treatment. Understanding the symptoms and causes of diabetic foot ulcers can significantly aid in prevention.

What are the Causes of diabetic Foot Ulcer?

As mentioned earlier, diabetic  Foot Ulcer is caused by a combination of

• Peripheral Neuropathy (Nerve damage)
• Poor Blood circulation
• High blood sugar levels

It will worsen the situation if not treated at the right time. Let’s check on the causes of diabetic  Foot ulcers in detail.

1. Peripheral Neuropathy:

Peripheral Neuropathy, also known as nerve damage, is a condition where prolonged high blood sugar levels damage the nerves, particularly in the feet. This may result in serious issues like loss of sensation, muscle weakness, and tingling or burning sensations.

• Loss of Sensation: When the sensation is lost, the patient will not notice minor injuries or cuts.
• Muscle weakness: Neuropathy or nerve damage can cause noticeable changes in the foot structure, leading to the pressure points that increase the risk of foot ulcers.
• Tingling Sensation: Neuropathy can cause discomfort like tingling or burning sensation in the early stages, but as it progresses it will lead to complete numbness.

2. Poor Blood Circulation:

Diabetes leads to many discomforts and one such discomfort is this peripheral artery disease (PAD). Peripheral artery disease (PAD) is a condition in which narrowed arteries reduce blood flow to the extremities. The most common symptoms noticed by the patients with PAD are pain or discomfort in their legs.

Reduction in the blood flow slows the wound healing period and increases the infection risk. In addition, the patient can feel cold and pain in the legs.

• Slow wound healing: For effective healing, it is essential that the blood supply provides enough oxygen and nutrients. Insufficient levels of oxygen and nutrients in the blood make it more difficult for the body to heal injuries.
• Increased Infection Risk: Individuals with diabetes often experience a compromised immune system, which significantly inhibits their ability to battle infections effectively. 
• Cold feet and Pain: Due to the reduction in the blood flow, the patient can feel discomfort in the legs and further increase foot problems.

3. High Blood Sugar Level:

Hyperglycemia, commonly referred to as high blood sugar levels, is a significant contributor to the development of diabetic foot ulcers. When blood sugar levels remain consistently elevated, they can lead to various complications, including neuropathy and reduced blood circulation.

These conditions weaken the immune system and compromise the body’s natural healing abilities, making it increasingly difficult for wounds to recover.

As a result, even minor injuries may escalate into

• Increased bacterial growth: High glucose levels create an environment where bacteria can develop vigorously. Due to the high bacteria growth, the risk of infection rises.
• Inflammation: High glucose levels will inhibit the body’s response to injuries, increasing the chance of chronic wounds.
• Thickened blood Vessels: Elevated sugar levels can lead to damage in blood vessels, which may result in impaired circulation. This thickening of blood vessels can further exacerbate issues related to blood flow and overall circulatory health.
  

Proper management of blood glucose through diet, medication, and regular monitoring is crucial in preventing these potentially serious complications.

Symptoms of diabetic Foot Ulcer:

Recognizing early foot ulcer symptoms can help prevent serious complications. Diabetic foot ulcers exhibit noticeable warning signs in their initial stages. Some of these warning signs include:

• Redness and Swelling
• Pain or tenderness
• Drainage or Pus
• Unpleasant Odor
• Discoloured Skin

If you notice any of the above-mentioned symptoms, consult the doctors without any delay.  Prevention is better than cure. Although diabetic foot ulcers are high at risk, they are largely preventable. However, prevention of diabetic foot ulcers is possible only with proper foot care, lifestyle, and diagnosis at the initial stage. There are diabetic foot ulcer strategies.

Who is at risk for diabetic foot ulcer?

Symptoms are not only signals but also warning signs sent by the body to alert us. The length of time of diabetes in a patient defines the risk of diabetic foot cancer and its complications. The longer a person has diabetes, the higher the risk of complications such as neuropathy.

Key factors that increase the risk of Foot Ulcer are:

• Poorly controlled Blood Sugar:

When the diabetes is not under control, then it will lead to prolonged high blood sugar levels, which will worsen the body’s healing abilities. When the blood remains high for a long period, it damages the blood vessels and nerves.

• Smoking and tobacco use:

Smoking and Tobacco usage is the worst habit and addiction to every individual. Talking about the diabetic s, smoking is the worst enemy as it narrows the blood vessels, reducing the blood circulation to the extremities.

• Improper footwear:

Footwear matters when it comes to footcare. Wearing tight and uncomfortable shoes increases the development of wounds and blisters in the foot. 

Wearing unfit footwear can cause friction and can cause blisters, corns, calluses, and pressure sores. Over time these injuries can turn into ulcers. Choosing comfortable footwear is advisable as it prevents foot complications.

• Obesity and inactivity:

Being physically inactive is not a healthy choice for anyone. Overweight increases the pressure on the feet. Over time, this added pressure can lead to pressure sores, which will later break down into open ulcers. 

Maintaining a healthy weight and being physically active can not only help in improving the blood circulation but also reduce the risk of developing the diabetic foot ulcers.

• Foot ulcer or amputation history:

Patients with previous diabetic foot ulcers or amputations are at high risk of recurrence. This is because of the peripheral neuropathy and blood circulation that caused the initial ulcer. 

In addition, the previous wound may have resulted in scar tissues and would have taken time to heal. If a foot has been amputated, the other foot may bear more weight and pressure, which increases the risk of developing new ulcers.

Prevention of diabetic foot ulcer: A smart solution:

Not every person living with diabetes is at risk for developing foot ulcers, but a significant number are, particularly those with poorly managed blood sugar levels. 

Factors such as nerve damage, inadequate blood circulation, foot deformities, and a history of ulcers or infections contribute to this risk. Additionally, behaviors like smoking, being overweight, and wearing ill-fitting shoes can increase the likelihood of foot problems.

Some prevention strategies:

• Maintain Proper Foot Care
• Regular Foot Inspections
• Wearing Comfortable Footwear
• Frequent Checks on Blood Sugar Levels
• Routine Medical Check-Ups
• Healthy Lifestyle

Let us look deep into the prevention methods.

1. Blood sugar control:

• Keep blood sugar levels within the target range through a balanced diet, regular exercise, and taking your medications as prescribed. 
• Check your blood sugar regularly to avoid complications like nerve damage and poor blood flow. 

2. Regular medical checkups:

• See a doctor or foot specialist for a foot exam at least once a year, or more often if you are at a higher risk. 
• This helps check for early signs of nerve damage and blood flow problems.

Prevent amputation with timely surgical care. Consult the best general surgeon in Coimbatore for diabetic foot ulcer treatment.

3. Proper foot care routine:

• Check whether there are cuts, blisters, redness, or swelling in your feet. 
• Wash your feet daily with mild soap or cleanser and lukewarm water. 
• Apply lotion to keep feet from getting dry and cracked.

4. Comfortable footwear:

• Wear comfortable shoes that fit well to protect against pressure points and injuries.
• Avoid walking barefoot, even at home, to prevent cuts and wounds. Choose diabetic socks that help with blood flow and reduce friction. 

5. Early detection & monitoring:

• Pay attention to symptoms like numbness, tingling, pain, or wounds that heal slowly.
• If a wound doesn’t start to heal in a few days, see a doctor to avoid infections or complications.

6. Treatment of diabetic Foot Ulcers: 

• Clean ulcers well and use antiseptics or dressings recommended by your doctor. 
• Take antibiotics if there are signs of infection, like pus, swelling, warmth, or a bad smell. 
• Severe cases might need surgery to improve blood flow. In the worst cases, amputation might be needed if the infection spreads and becomes life-threatening.
