Diabetes is a result of your body’s inability to produce or use insulin. Insulin is a hormone that allows your body to turn glucose, or sugar, into energy. If your body has difficulty metabolizing glucose, it can lead to high blood sugar levels. This can affect your body’s ability to heal wounds.
In people with diabetes, wounds tend to heal more slowly and progress more quickly, so it’s important to know what to look out for.
Although cuts, grazes, scratches, and blisters can occur anywhere on the body, the feet are one of the most common places of injury. A small wound on the foot can quickly develop into a foot ulcer.
Foot ulcers can become serious if left untreated. About 15 percent of people who have diabetes develop foot ulceration.
For this reason, it’s crucial to do regular self-checks and closely monitor any wounds closely. Catching wounds early is the only way to reduce your risk of complications.

When you have diabetes, a number of factors can affect your body’s ability to heal wounds.
High blood sugar levels
Your blood sugar level is the main factor in how quickly your wound will heal.
When your blood sugar level is higher than normal, it:
- prevents nutrients and oxygen from energizing cells
- prevents your immune system from functioning efficiently
- increases inflammation in the body’s cells
These effects slow down wound healing.
Peripheral neuropathy can also result from having blood sugar levels that are consistently higher than normal. Over time, damage occurs to the nerves and vessels. This can cause the affected areas to lose sensation.
Neuropathy is particularly common in the hands and feet. When it happens, you may not be able to feel wounds when they occur. This is one major reason why foot wounds tend to be
People with diabetes are
Immune system deficiency
Many people who have diabetes also have problems with immune system activation. The number of immune fighter cells sent to heal wounds, and their ability to take action, is often reduced. If your immune system can’t function properly, wound healing is slower and your risk of infection is higher.
If your immune system isn’t functioning at its best, your body may struggle to fight off bacteria that cause infection.
Higher-than-normal blood sugar levels also increase the possibility of infection. This is because bacteria thrive on the extra sugar in the bloodstream. High blood sugar levels can also prevent immune cells from being able to fight off invading bacteria.
Wounds present a real cause for concern. If they’re not carefully monitored, they can quickly progress into an infection or more serious complication.
The most serious concern is amputation. People with diabetes are 15 times more likely to have amputations as a result of foot wounds or ulcers. Here’s why this happens and what you can do to prevent it.
To help the healing process, follow these tips:
Do regular self-checks. Catching wounds early is the key to avoiding infections and complications. Make sure you do daily self-checks and look for new wounds, especially on your feet. Don’t forget to check in between and under your toes.
Remove dead tissue. Necrosis (dead cells) and excess tissue often occur with diabetic wounds. This can promote bacteria and toxins and increase wound infection. It can also prevent you from being able to inspect the underlying tissue. Your doctor will often help you with the removal process.
Keep dressings fresh. Regularly changing dressings can help reduce bacteria and maintain appropriate moisture levels in the wound. Doctors often recommend special wound care dressings.
Keep pressure off the area. Pressure can cause wear and tear that damages the skin and leads to a deeper wound or ulcer.
If you’re dealing with a foot wound, consider wearing white socks during the healing process. This will make it easier to see blood or other signs of drainage on your socks.
See your doctor if you experience any of the following:
- loss of sensation
- persistent pain
You should also see your doctor if your symptoms worsen or last longer than a week.
Any break in the skin of your feet is cause for concern, so if you’re unsure about the wound, see your doctor. They can identify the wound and advise you on how best to care for it. The faster you get appropriate treatment, the more likely you are to prevent complications.
There are a few things you can do to boost your immune system and aid in wound healing.
Eat a healthy diet. Diet has a direct influence on blood sugar levels, so maintaining proper nutrition is key. If you can consistently maintain healthy glucose levels, you’re more likely to avoid wounds and heal faster should a wound occur.
People with diabetes can often maintain better blood sugar control by avoiding processed carbohydrates, added sugars, and fast food. It also helps to increase your intake of fiber, fruits, vegetables, and legumes. Good nutrition provides what your body needs for faster wound healing, such as vitamin C, zinc, and protein.
Stay active. Exercise helps improve insulin sensitivity. This helps sugar in the bloodstream enter your cells more efficiently, which promotes healing and health.
Quit smoking. Smoking decreases your cells’ ability to carry oxygen. Smoking also disrupts the immune system and increases your risk of vascular disease.
