Diabetes and Foot Problems

Foot Problems1

How can diabetes affect my feet?

Chronically high blood sugar (glucose) levels can be associated with serious complications in people who have diabetes. The feet are especially at risk. Two conditions called diabetic neuropathy and peripheral vascular disease can damage the feet (and other areas of the body) in people who have diabetes.

What is diabetic neuropathy?

Chronically high sugar levels associated with uncontrolled diabetes can cause nerve damage that interferes with the ability to sense pain and temperature. This so-called “sensory diabetic neuropathy” increases the risk a person with diabetes will not notice problems with his or her feet.

Nearly 10% of people with diabetes develop foot ulcers due to peripheral vascular disease and nerve damage. People with diabetes may not notice sores or cuts on the feet, which in turn can lead to an infection. Nerve damage can also affect the function of foot muscles, leading to improper alignment and injury. 

What is peripheral vascular disease?

Diabetes is associated with poor circulation (blood flow). Inadequate blood flow increases the healing time for cuts and sores. Peripheral vascular disease refers to compromised blood flow in the arms and legs. Poor blood flow increases the risk that infections will not heal. This, in turn, increases the risk of ulcers and gangrene, which is tissue death that occurs in a localized area when there is an inadequate blood supply.

What are common foot problems of people with diabetes?

The following images show common foot problems that anyone can get; however, those with diabetes are at increased risk for serious complications associated with these conditions, including infection and even amputation.

Athlete’s foot

Fungal infection of the feet is called athlete’s foot. Cracked skin, itching, and redness are associated with the condition. Fungus enters cracks in the skin causing an infection that must be treated with antifungal medications. Oral medications or topical creams may be used to treat athlete’s foot.

Fungal nail infection

Thick, brittle, yellow-brown, or opaque nails are common with fungal nail infections. The infected area may crumble or seem to pull away from the rest of the nail. Fungus thrives in the warm, moist, dark environment created by wearing closed-toed shoes.

Nail injury also increases the risk of fungal nail infection. These infections are difficult, but not impossible, to treat. Oral medications work best to treat fungal nail infections. Topical treatments are only effective for a few types of fungal nail infections. Sometimes, surgery is necessary to remove infected areas of the nail.


Calluses are hard areas of thickened skin that build up on the bottom of the feet. Uneven weight distribution, a skin abnormality, or ill-fitting shoes may cause calluses. Use these tips to care for calluses:

Rub the area with pumice stone after a shower or bath. Ask your doctor the best way to do this.

Place cushioned insoles or pads in shoes.

Ask your doctor about prescription medication to soften calluses.

It’s normal to have some calluses. It’s important to never try to cut a callus using a sharp object. Doing so can cause serious injury.


A corn is a thickened, button-like area of skin that builds up between the toes or near a bony area of a toe. Pressure and friction cause corns. Use these tips to care for corns:

Rub the area with a pumice stone after a shower or bath. Consult your doctor before doing this.

Avoid over-the-counter corn removal treatments.

Never try to cut the corn with a sharp object. Doing so can cause serious injury.


Blisters are raised, fluid-filled areas of skin that form due to friction. Popping a blister is not a good way to treat it since the skin covering the area helps guard against infection. To care for a blister, keep the area clean, apply antibacterial cream or ointment, and cover it with a bandage to reduce the risk of infection. 

Dry skin

Dry, cracked skin allows bacteria and other germs to enter your body, potentially causing an infection. Moisturizing soaps, lotions, and other products can help keep the skin barrier soft, intact, and healthy.

Foot ulcers

Foot ulcers are dangerous wounds that can affect people with diabetes. When a minor scrape, skin break, or sore on the foot becomes infected, a sore can result. In people who have diabetes, sores heal slowly or fail to heal.

Early diagnosis and treatment are necessary to reduce the risk of complications. Your doctor is the best source of information on how to properly care for a foot sore.

Diabetes and Foot Problems 

Prevention Tip #1

Living with diabetes requires you to pay special attention to your health and your condition. Follow your doctor’s instructions regarding diet, exercise and medication. Keeping your blood sugar (glucose) levels within the recommended range is one of the best things you can do to control your condition and protect your feet.

Prevention Tip #2

Carefully inspect your feet daily for redness, blisters, sores, calluses, and other signs of irritation. Daily foot checks are especially important if you have inadequate blood flow.

Prevention Tip #3

Follow these foot care tips to properly care for your feet:

  • Wash your feet daily with non-irritating soap and warm water.
  • Avoid soaking your feet.
  • Dry your feet completely after bathing, paying special attention to the areas between the toes.
  • Avoid applying lotion to the areas between the toes.
  • Ask your doctor which lotion is best for your skin type and health condition.

Prevention Tip #4

After bathing, use a pumice stone or emery board to smooth hardened areas of the feet that contain corns and calluses. Working in one direction is most effective. Consult your doctor on the proper way to use a pumice or emery board.

Prevention Tip #5

Use the following toenail care tips to help prevent ingrown toenails.

  • Once a week, examine your toenails.
  • Trim toenails straight across using a nail clipper.
  • Avoid rounding or trimming down the sides of toenails.
  • Smooth rough nail edges with an emery board after clipping.

Prevention Tip #6

Proper footwear, socks, and stockings can go a long way to help protect your feet. Follow these tips:

Choose well-fitting socks and stockings that contain soft elastic.

  • Wear socks to bed if your feet get chilly.
  • Avoid sandals and walking barefoot, even at home.
  • Wear properly-fitting shoes.
  • Choose shoes made of soft materials – such as leather or canvas – and take time to break them in.
  • Protect your feet by always choosing slippers or closed-toed shoes.
  • If you need roomier shoes due to bunions or other deformities, extra wide shoes are available online and in specialty stores.

Prevention Tip #7

Follow these tips to keep blood flowing to your feet:

  • If you can, prop your feet up when sitting down
  • Wiggle your toes frequently.
  • Take frequent breaks to flex and point your toes and circle your feet in both directions.
  • Avoid crossing your legs, especially for long periods.

Prevention Tip #8

Avoid smoking and if you do smoke, quit. Smoking aggravates blood flow problems.

Prevention Tip #9

People who have diabetes should see a foot doctor (podiatrist) every 2 to 3 months, even when not experiencing foot problems. At each check-up, ask the doctor to thoroughly examine your feet. An annual foot exam should include:

  • An examination of the tops and bottoms of the feet and in between the toes
  • An assessment of skin warmth and redness
  • An assessment of pulses in the feet and temperature of the feet
  • An assessment of sensation using a mono-filament tool

Prevention Tip #10

Blood Sugar Control is of the utmost importance to prevent foot complication. Follow a healthy diet, like the Manna Diet as described in the free e-book. Take the Manna Blood Sugar Support supplement with each meal to control blood glucose levels the natural way.

Take the Manna Blood Circulation Support supplement to help increase blood flow, especially to the feet.
