Diabetic Foot: Understanding Its Causes and Research-Based Strategies to Reduce the risk 

Key Highlights: 

Introduction 

Millions around the world suffer from diabetes. One harsh complication of this condition is the diabetic foot. It can cause serious disability and even demand amputation if not looked after on time. That’s why knowing the causes and methods to reduce the risk is of key importance. 

This article aims to offer an overall view of what a diabetic foot is. We’ll discuss what causes it, and which group of individuals run a higher risk. Also, we’ll delve into several tactics to avoid and manage it. These strategies are research backed. Lastly, we’ll touch upon some common questions that you may have about this topic. 

What is Diabetic Foot? 

It’s more of an umbrella term. It points to multiple foot issues that a person with diabetes might face. These problems could be ulcers, infections, or gangrene (tissue dying). Without management, these can result in a toe, foot, or leg having to be amputated . 

Diabetic foot issues arise more in patients who’ve had diabetes for a long time. Especially ones who haven’t managed their diabetes well. This can cause the nerves to get damaged (neuropathy) and cut off blood flow to the feet. These factors increase the likelihood of wounds and infection. These are hard to treat and can get worse if not checked in time. 

Symptoms of Diabetic Foot 

The signs of a diabetic foot can shift based on the root cause. Here are some common signs : 

Causes of Diabetic Foot 

Several factors give rise to diabetic foot issues they are as follows. 

1. High blood sugar levels 

When blood sugar levels go up in diabetes, it can harm blood vessels and nerves. It leads to poor blood flow and lowered feeling in the feet. These factors boost the chances of foot problems. Any injury or infection can worsen if not managed immediately.  

2. Nerve damage (Neuropathy) 

Diabetic neuropathy is a top cause of diabetic foot issues. This kind of nerve damage can hit the sensory, motor, and autonomic nerves in the feet. It leads to numbness, weakness of muscles, and low sweat production. All these mean injuries or foot irritation might go unnoticed. This makes serious complications more likely. 

3. Poor circulation 

With diabetes often comes peripheral artery disease. This entails narrower, harder blood vessels. This reduce the blood supply to arms and legs. Poor blood flow restricts oxygen and nutrients from getting to the feet. This slows down the healing process and increases the chance of infections. 

4. Infections 

Persons who have diabetes are more likely to get infections. A small cut or blister on the feet can turn into a deep-set infection if you ignore it. Poor blood flow and nerve damage can contribute to these infections. These add to the risk of tissue harm and other issues. 

Risk Factors for Diabetic Foot 

A few factors increase the odds of developing diabetic foot issues. These are as follows.  

1. Uncontrolled diabetes 

Poor control of diabetes can result in long-standing high blood sugar levels. That, in turn, increases the risk of nerve damage and poor blood circulation. Both can assist in causing diabetic foot problems. 

2. Obesity 

Extra weight places added stress on the feet. This increases the likelihood of injury and complicates the healing process of existing wounds. 

3. Smoking 

Smoking tightens blood vessels and hampers blood flow. This slashes the blood that gets to the feet and makes diabetic foot problems more probable. 

4. Foot deformities 

Persons with foot anomalies like bunions, hammertoes, or flat feet might face uneven pressure on their feet while walking. This can result in calluses, corns, and finally ulcers. If you do not manage these on time, they can worsen. 

Avoiding Diabetic Foot 

Making use of methods that are research-based to avoid diabetic foot may help drive down the risk of diabetic foot issues. These are as follows.  

1. Blood sugar management 

It is important to exercise good control over blood sugar levels to reduce diabetic foot risks. Correct blood sugar management may help lessen nerve and blood vessel damage risks.  

2. Regular foot examination  

Checking your feet regularly and looking after them may help ward off diabetic foot problems. This allows you to identify issues early on and act immediately.  

3. Proper foot hygiene 

 Wash your feet with lukewarm water and mild soap daily. Make sure they are totally dry, particularly between the toes. This avoids infections and other foot problems. 

4. Safe and comfortable footwear 

Wear shoes that fit well and offer good support and cushion. This saves your foot from injury and lowers the chances of ulcers. Stay away from tight shoes or high heels. These can add to pressure points and make existing foot problems grow worse. 

5. Improving circulation through physical activity 

Regular workouts enhances blood flow in your limbs. This may help lower the risks of foot problems. Choose low impact exercises such as swimming, cycling, or walking. These boost blood flow without burdening your feet too much. 

6. Routine checkups with health professionals 

Go see your healthcare provider often. This helps to figure out and deal with any foot problems while they’re still  mild. Your doctor may recommend some extra steps to reduce risk. These could be custom orthotics or special footwear that helps bring down the risk of diabetic foot problems.

Management Options for Diabetic Foot 

Diabetic foot needs a quick and custom-fitted management strategy to avoid risks and heal. These are as follows.  

1. Medications 

Your doctor may suggest drugs to address key causes of foot problems and the resulting risks. They are as follows. 

If there’s an infection, your doctor may recommend antibiotics. These fight harmful bacteria and help in healing. 

Your doctor may prescribe painkillers to ease discomfort and inflammation from diabetic foot problems. 

Correct management of diabetes plays a big part in avoiding and managing foot problems. Your doctor may adjust your existing medications or introduce new ones to manage your blood sugar levels . 

2. Surgical procedures 

In severe cases, surgery might be needed to manage foot problems. They are as follows.  

Debridement is when dead or infected tissue is removed from the problem area. This promotes healing and stops infection spread. 

Revascularization is a surgery meant to improve the blood flow to the problem area. This may aid in healing diabetic foot ulcers. 

In serious situations, if usual management options don’t work and there’s high risk of deep infection or gangrene, you might need an amputation. This is done to safeguard the patient’s whole health and well-being. 

3. Wound care and management 

Looking after the wound the right way is critical for the successful management of foot problems. It could involve keeping a clean and dry condition around the wound, changing the dressing  regularly, and taking the pressure off through orthotic devices or specialized footwear. 

4. Lifestyle changes 

Adopting and sticking to a healthy lifestyle may play a big part in avoiding and managing foot problems. This means managing diabetes right, doing regular workouts, eating healthy, and giving up smoking. 

When to See a Doctor? 

Knowing when your foot issues are getting worse is key in order to seek early help and avoid serious risks. Do see a doctor if you notice any of the following.  

Taking action early may greatly improve how diabetic foot issues turn out. It also may reduce long-term risk. 

Conclusion 

Foot problems related to diabetes pose a big risk to the health and well-being of people with diabetes. Knowing the causes and ways to avoid them that are research-backed is key.  

By taking charge of managing your diabetes, regularly caring for your feet, and seeking early medical help as needed, you may avoid serious risks. These can be sores or amputation. Remember, caring for your health today can boost your lifestyle quality for many years to come.
