    What is a Diabetic Foot Ulcer?

    A ‘diabeticfoot’, also known as diabetic foot ulcer is a wound or an open sore that develops in diabetic patients if their leg gets injured somehow. Diabetic foot ulcers are considered as complication that arises when the skin tissues around the injury start to break down and expose the layers underneath. One of the worst things about these ulcers is that they cannot be managed through diet, exercise, or even insulin treatment. Therefore, it is always advised to get a timely treatment for a ulcer affected diabetic foot.

    How does it form?

    Wound healing is a natural mechanism of the human body. The key feature of wound healing is the repair of the lost extracellular matrix (ECM) that is the largest component of the dermal skin layer. Diabetes is one of the diseases that disturbs the wound healing process by delaying the formation of ECM. It also increases the risk of inflammation in the wounds that further delay the formation of mature granulation tissue and reduction in the wound tensile strength.

    The delayed formation of the granulation tissue is the key reason for the formation of a diabetic foot ulcer. Other factors, such as poor circulation, foot deformities, and trauma in the foot also contribute to this condition. Patients with diabetes develop neuropathy which reduces or causes a complete loss of the ability to feel pain in the feet. The nerves get damaged due to consistently elevated blood sugar levels without exhibiting pain or other symptoms. Due to this, patients often stay unaware of the blisters, cuts, and injuries in their foot which results in the formation of a diabetic foot ulcer.

    Types of disease

    • Neuropathic Ulcers
    • Ischemic Ulcers
    • Neuroischemic Ulcers

    Diabetic Foot Ulcer Causes and Symptoms


    • Poor circulation
    • High blood sugar
    • Nerve damage
    • Hypertension
    • Venous Insufficiency


    • Swelling and discoloration of the skin
    • Foul-smelling discharge
    • Pain and firmness in the wound
    • Callused or thickened skin
    • Partial or complete gangrene

    Diabetic Foot Ulcer Diagnosis


    • X-Ray- This imaging test is used to assess the alignment of the bones in the foot that contributes to the ulcer. The X-Ray will also help to determine the bone mass loss that happened due to diabetes.
    • MRI Scans- The magnetic resonance imaging test creates a computerized 3-D image of the soft tissues inside the body. The doctor suggests this test to determine the extent of damage caused by the ulcer and also reveal if there is any inflammation present in the foot.
    • Blood Test- It is recommended when there are signs of infection present with the ulcer. A blood test is done to screen the infection.

    Self Diagnosis

    The diabetic foot ulcer can be clearly seen on the foot as the tissues around the wound or sore will slowly start to die. If you have peripheral neuropathy, the nerve in the foot will be damaged, which will reduce the sensations in the feet and legs. Due to this, you may not notice the pain of the blister of injury in the foot.

    You should inspect your foot daily if you have diabetes to ensure that an ulcer is not forming. Even a small blister or cut can quickly progress into an ulcer if it goes unnoticed. Therefore, it is always advised to a diabetic patient to be extremely careful while performing any kind of activity.

    Diagnosis by Doctor

    Visiting a vascular specialist is always the right approach to seek treatment for diabetic foot ulcers. He/she will diagnose the condition during a physical examination. The doctor will ask when you first noticed the ulcer and if you have other conditions, such as lower extremity arterial disease or peripheral neuropathy.

    The doctor will inspect the foot, toes, and toenails for cuts, blisters, scratches, or ingrown toenails that can lead to the formation of foot ulcers.

    The doctor may also ask you to stand and walk to analyze how the body weight is distributed across the bones and joints. The shape of the foot will also be checked as abnormal alignment of the foot can also increase the risk of ulcers.

    After gathering your medical history and examining your foot physically, the doctor may suggest an X-ray, MRI scan, or blood tests to obtain more information about the ulcer.

    Diabetic foot Ulcer Severity

    Grade 1 

    Intact Skin

    In this grade, no diabetic foot ulcers are present. However, there is a significant risk of developing one of the patients getting injured.

    Grade 2

    Superficial Ulcer of Skin or Subcutaneous Tissue

    The is the early stage of diabetic foot ulcer. In which, a surface ulcer is present in this grade that involves the full thickness of the skin tissues but doesn’t yet involve the underlying tissues.

    Grade 3

    Ulcers Extension into Tendon, Bone, and Capsule

    It is past diabetic foot ulcer’s early stage, the ulcer becomes deep and penetrates the surface, down to the muscles, ligaments, tendon, joint capsule, deep fascia, etc.

    Grade 4

    Deep Ulcer with Osteomyelitis or Abscess

    At this grade, the ulcer reaches the subcutaneous connective tissue layer. Inflammation, osteomyelitis, or abscess may also be present. It can also include infection in the tendon, muscle, joint, or bone. This may also result in sore diabetic foot.

    Grade 5

    Partial Foot Gangrene

    Initial stage of diabetic gangrene of foot is limited to the toes and forefoot, in this grade, the tissues around the ulcer start to decay. Gangrene or tissue death occurs in the localized portion of the foot.

    Grade 6

    Whole Foot Gangrene

    In this grade, the diabetic gangrene of foot is extensive as the affected area is covered with ulcers. It is present in the whole foot region and may require amputation if not treated on time.

    Risks & Complications

    During the Surgery 

    In general, the surgical complications and risks associated with diabetic foot ulcer treatment include:

    • Allergic or other reaction to the anesthesia-Everybody reacts in a different way to the anesthetic agent. Moreover, there is a possibility that you may not be aware of your allergies. Due to both these reasons, the patient may have an allergic reaction to anesthesia or his/her body may start itching.
    • Bleeding-The ulcer contains dead tissues and while they are being removed, the blood vessels underneath may need removal as well due to which the ulcer will bleed. If the ulcer is very big, there can be an excessive amount of blood loss during the treatment.
    • Pulmonary embolism

    – Blood clots are also present in the ulcer which may break down and travel to the lungs resulting in a pulmonary embolism that can be fatal.

    • Arrhythmia or heart attack (irregular heart rhythm)-

    As diabetic foot ulcer surgery sometimes involves dead tissue extraction, patients feel like it is major surgery. Due to this, they feel nervous during the surgery and may suffer from arrhythmia.

    *You should know that diabetic foot ulcer treatment is not necessarily a major surgery. It completely depends on the severity of the condition. For instance, if you have an ulcer of grade 3, debridement will be enough to improve the healing of the ulcer whereas, for a grade 5 ulcer, you may require vascular reconstruction which involves tendon lengthening or transfer as the infection usually reaches the bones in this grade.

    If Left Untreated

    In case you don’t seek treatment for diabetic foot ulcer in time, you will have to face the following complications:

    • Skin and bone infections may occur due to severe nerve and blood vessel damage.
    • Abscess also occurs due to infection in the ulcer which will create a pocket filled with pus or blood.
    • Gangrene occurs when the blood vessels are damaged and the blood flow to the area is cut off. The tissues in the affected area will start dying.
    • Deformities are another complication of leaving the foot ulcer untreated as it will weaken the muscles in the feet and lead to problems like hammertoes, prominent metatarsal heads, pes cavus, claw feet, etc. halting your ability to walk.
    • Charcot’s foot is another complication that often occurs in diabetic patients. The bones become so weak that they can break and the nerve damage around the area lessens the sensation, thereby preventing from realizing this problem. As a result, you continue walking on the broken bones and the foot shape will start to change.
    • Amputation is the last thing that might need to be done if you leave diabetic foot ulcers untreated. When the site is infected and the tissues continue to die off, there is a higher risk that the same thing will happen to other body parts. As a result, the surgeon will have to amputate the foot to prevent the infection from spreading.


    Even after having surgery, there are slight chances of complications which you should look out for, such as:

    • Infection at the incision site- As the ulcer is already not healing properly, there is a chance that the infection may return and the wound will become infected again.
    • Damage to the other blood vessels or organs- There are chances that during the extraction of dead tissues or while removing the infection, the healthy tissues or blood vessels may get damaged.
    • High fever– After surgery, you may experience high fever as a side effect of the anesthetic agent.
    • Burst artery or aneurysm rupture- Though it rarely happens, there is a chance that arteries may burst after the surgery, or an aneurysm may occur in a weak blood vessel.

    Diabetic Foot Ulcer Prevention

    Proper foot care can help you prevent a lot of common problems and treat them before they lead to serious complications. Here are the tips that will help you prevent foot problems:

    • Take care of your overall health diabetes and follow your doctor’s advice to keep your blood sugar levels in the ideal range.
    • Wash your feet in warm water and test the temperature with your elbow as the nerve damage in the feet will make you unable to feel the coldness or hotness of the water. Also, make sure that you do not soak your feet and dry them well.
    • Check your feet for sores, blisters, redness, calluses, or other injuries every day, especially if you have poor blood flow in the feet.
    • Make sure that your feet don’t get too dry. Keep it moist using lotion but don’t put lotion between your toes. Also, make sure that you consult your doctor before using any type of lotion for the feet.
    • If calluses or smooth corns form in the feet, use an emery board or pumice stone to remove them after you take a bath or shower. The skin in the feet will be soft during and after the shower. Hence, it will be easier to remove.
    • Always wear stockings or socks that fit you well and have soft elastic. Also, avoid walking barefoot or wearing sandals to ensure that your feet don’t get injured. Prefer wearing closed-toed shoes or slippers.
    • Protect your feet from extreme heat and cold.
    • Make sure that the blood flow in your feet is maintained properly. Keep your feet up while sitting, move your ankles, wiggle your toes, and don’t sit cross-legged for a longer duration.
    • If you smoke or drink alcohol, stop as soon as possible. Both these habits can make the existing foot problem worse, especially smoking.
    • Visit the diabetes doctor regularly and make sure that the doctor checks your feet during each checkup.
    • If an ulcer has already formed, contact a vascular specialist without any delay.

    When to consult a doctor?

    If you are a diabetic patient, you should consult a doctor right away if you experience one or more of the following:

    • Changes in your foot shape
    • Changes in the skin in the feet, such as a wound, redness, darkness, or foul odor coming from the feet
    • Hair loss in the feet and legs
    • Sores in the affected foot.
    • Any cut or injury in the body which is not healing well.
    • Loss of feeling or sensation in the toes, feet, or legs
    • Pain or tingling sensation in the feet or legs
    • Thick or yellow toenails

    Questions to ask your doctor?

    • What is the procedure I will undergo?
    • Are there any other alternative treatment options besides surgery?
    • What benefits does surgery have in terms of pain relief and leg & foot function?
    • What is the success rate of diabetic foot ulcer surgery?
    • Will you have to undergo surgery multiple times to completely treat the foot ulcer?
    • What are the chances of having a diabetic foot ulcer again?
    • How much pain will I have after the surgery?
    • Will I have any disability after ulcer surgery?
    • When can I return to work?
    • When will I be able to walk again?

    Diabetic Foot Ulcer Treatment options & cost


    The treatment of a diabetic foot ulcer starts by cleaning or disinfecting the area. If the ulcer is infected, the doctor will first prescribe antibiotics to clear up the infection and prevent it from spreading to the bone. After the wound is cleaned, a bandage will be applied to keep the wound sterile while it heals. The doctor will also show you how to do the cleaning and dressing on your own. An anti-bacterial ointment may also be provided to speed up the healing process and prevent infection.

    Off-loading or TCC (Total Contact Casting)– It is another non-surgical treatment that involves relieving the pressure from the ulcerated area through an external means. Most commonly, the doctor will ask you to stay off your feet to prevent the infection in the ulcer from getting worse. To take the load off from your feet, the doctor will recommend wearing any of the following:

    • Shoes that are specially designed for people with diabetes
    • Casts
    • Foot braces
    • Compression wraps
    • Shoe inserts

    Hyperbaric Oxygen Therapy- This is a treatment that is not available in all medical centers but can be effective to a great extent in improving the healing of diabetic foot ulcers. A chamber is used where the patient lies on his/her back on a bed. The chamber is filled with 100% oxygen which increases the amount of oxygen in the bloodstream ten times. This speeds up the healing of the ulcer by stimulating the growth factors and stem cells. Sometimes, multiple sessions are done of this therapy to ensure that the wound heals properly.

    Types of Surgery

    When the ulcer cannot be treated using non-surgical methods, the doctor will consider using the surgical procedure for:

    • Removal of pressure on the affected region, including shaving or excision of the bone.
    • Correction of the deformities in the legs, such as hammertoes, bony bumps, etc.
    • Treatment of infection, such as osteomyelitis by surgically removing the infected bone.

    Debridement- It is a procedure that involves the removal of the hyperkeratotic tissue, fibrin, biofilm, and necrotic tissue from the ulcer wound to facilitate healing. With this technique, the wound healing process can be initiated by the small vessels that transport fresh blood to the edges of the debrided wound.

    Reconstructive Foot & Ankle Surgery- This method of treatment involves a thorough musculoskeletal examination, plain radiographs, CT scans, and MRI scans that helps to determine the surgical plan. It is a very complex procedure that is done in a systematic manner:

    • Arthroplasty
    • Osteotomies
    • Resection
    • Arthrodesis
    • Tenotomies
    • Tendon transfer
    • Tendon lengthening

    The goal of the surgery is foot rebalancing and creating a plantigrade foot that can distribute the pressure in the leg. It is considered a type of internal surgical offloading.

    Vascular Reconstruction- In case the blood vessels in the legs are extremely damaged and you have arterial lesions with intractable pain and gangrene, the doctor will have to consider vascular reconstruction for the treatment of diabetic foot ulcers. It involves using synthetic grafts or blood vessels that are taken from other areas of your body and using them to recreate the blood vessels that were damaged due to ulcers. It restores the blood flow in the wound and allows it to heal.

    Surgery Preparation

    To prepare you for diabetic foot ulcer surgery, the doctor will give you clear instructions, including:

    • Stop medications like blood thinners before the surgery as they can increase the risk of excessive blood loss.
    • Stop eating or drinking at least 8 hours prior to the surgery.
    • Do not take aspirin for at least one week before the surgery.
    • Do not shave the surgical site for at least 2 days before the surgery date.

    What to expect during the surgery?

    During the surgery, the doctor will use spinal anesthesia to numb the lower half of your body. Once you are under anesthesia, you won’t be able to feel any kind of pain or discomfort during the procedure. There is a chance that you might be awake during the procedure and hear the machine running. To make sure that you don’t feel stressed during the surgery, the doctor may also give you anti-anxiety pills.

    After the Surgery

    After the surgery completes, you will most probably be asleep. You will be placed in the observation room until the anesthesia wears off. Afterward, you will be shifted to your ward. Depending on the procedure used for the treatment of diabetic foot ulcers, you may need to stay in the hospital for 24-72 hours. The doctor will closely monitor your condition after the surgery to make sure that there are no risks of complications.

    Immediately after the surgery, you will feel numbness in the lower half of the body. Later, you may feel pain or discomfort for which the doctor will prescribe painkillers. The doctor will apply a splint to cover your foot and lower leg for proper support.

    You will have to take complete bed rest for at least two days. After the doctor ensures that the wound is healing properly, you will be discharged. The doctor will also provide a detailed recovery plan to help you get back to your feet as soon as possible.

    Diabetic Foot Ulcer Insurance coverage

    The diabetic foot ulcer treatment will be covered under insurance as it has the potential to turn into a life-threatening condition. Most vascular diseases are covered in health insurance policies as they are considered critical illnesses. However, the amount of coverage you have will be different depending on the insurance policy you have and the disease for which you are seeking treatment.

    Most of the insurance companies, including Star Health Insurance, New India Health Insurance, Bajaj Allianz, Religare, ICICI Lombard, etc. provide ample coverage for vascular diseases and also have an easy and simple claim process. You can choose cashless payment or reimbursement to pay for the treatment you are seeking. But make sure that you discuss everything with the insurance provider to understand the terms and conditions of the policy.

    Recovery rate

    The recovery rate after having diabetic foot ulcer surgery varies from patient to patient depending on the severity of the condition and how the patient’s body responds to the treatment.

    In most cases, the wound will take around three to six weeks or even more (in severe cases) to heal properly. Throughout the recovery period, the patient will have to wear a cast to provide support to the leg and foot during walking and other activities. And even after the cast is removed, the doctor will suggest wearing a leg brace to assist in movements, reduce the weight-bearing forces, and correct the shape of the body.

    Frequently Asked Questions

    How common is diabetic foot ulcer?

    More than 15% of patients who have diabetes suffer from diabetic foot ulcers at some point in life. Thus, it is very common to develop a foot ulcer if you don’t pay attention to the condition and manage it properly.

    Can a diabetic foot ulcer be treated at home?

    No. A diabetic foot ulcer cannot and should not be treated at home. In most cases, the ulcer becomes infected which further delays the healing process increasing the chances of infection. Removing the infection is not possible with home remedies. You should always consult a doctor for proper treatment of foot ulcers.

    Why a foot ulcer won’t heal?

    A foot ulcer won’t heal if you have peripheral artery disease (PAD). It will cause malfunctioning in the circulatory system which won’t allow the ulcer to heal properly. For a non-healing ulcer, you should know that there are minimally invasive treatment methods available for such ulcers.

    Can I apply a cream to a diabetic foot ulcer?

    Yes. You can use certain creams or moisturizers to promote the healing of the diabetic ulcer. Doctors often advise patients that contain urea as it will create a barrier film over the wound and aids in healing.

    How do you know that your foot ulcer is infected?

    The signs of infection in a diabetic foot ulcer are quite obvious. You will experience pain, tenderness, sensitiveness, and firmness in the wound. In addition to the pain, you may also notice swelling or irritation in your foot.

    What does gangrene in a foot ulcer look like?

    Gangrene in the foot ulcer looks normal at first. However, as the condition becomes serious, the skin will turn pale, then gray, and ultimately purplish red. The skin tissues will start dying off and the muscles underneath will be exposed.

    Is it always important to take antibiotics for foot ulcer treatment?

    No. Treatment of diabetic foot ulcers using antibiotics won’t be required if the ulcer is not infected. In case mild soft tissue infection is present, it can be treated using oral antibiotics such as clindamycin, dicloxacillin, cephalexin, etc.
