What do you know about finger gangrene?
Gangrene of the toe occurs when blood does not reach the toes and blackness of the toes occurs. In the following we want to talk more about this issue. If you also have blackening of your big toe due to circulatory disorders, If you have gangrene of the toe due to circulatory disorders, We recommend that you read the rest of this article.

Introduction
Sometimes conditions occur in the body during which insufficient blood flow reaches a part of the body and some tissues of the body and dies due to impaired blood supply to the tissue.
And this disorder can occur in any part of the body, but usually what is better known is that the toes and fingers are the areas that may first develop gangrene. Also, the presence of an infection or a long-term problem in the blood flow above the blackened area can justify the blackening of your finger.
What is gangrene?
Definition of gangrene refers to the death of body tissues. The cause of death of body tissues in the gangrene process is due to insufficient blood flow to the tissue or a bacterial infection in that area that leads to finger blackening and death. Gangrenes can generally occur in any part of the body and in any tissue of the body, but they are usually more common on the limbs, meaning that the toes are more prone to gangrene than any other part of the body, but gangrene can affect different parts of our feet and hands as well as muscles and internal organs. We also occur there are various diseases and disorders that damage the arteries.
They damage and affect blood flow. These include uncontrolled diabetes. Also, people with atherosclerosis of the arteries have a higher risk of experiencing toe blackening due to impaired blood flow. In the following, we want to mention more about finger blackening due to circulatory disorders and other causes of finger blackening.
What causes gangrene?
What are the causes that damage the walls of the arteries? What are the conditions that can cause one of our toes to turn black? Here are some common causes of black toe:
- Infection
Sometimes there are bacterial infections that can cause tissue death and necrosis, tissue loss, and eventually blackening of the finger.
- Blackening of the finger following blows
Such as injuries resulting from gunshot wounds or, for example, more severe injuries in car accidents, which can cause bacteria to penetrate deep into the body in unprotected areas, resulting in serious deep bacterial infections and cause the death and gangrene of part of the tissue.
- Lack of adequate blood supply
Blood flow must be adequately provided for the life of various tissues. In fact, oxygen and nutrients are provided by the proper blood flow to nourish the cells of different tissues of the body If any disturbance in the blood flow occurs and, for example, a blood vessel in the upper leg becomes narrow, or it pressed or cut off during accidents or surgery; it no longer reaches the cells of the tissues below that blood vessel and these tissues can no longer survive and the dead tissue turns black.
Risk factors
In this section, we want to say what predisposing factors are there that if a person has them, the risk of developing gangrene in that person will increase. Consider the following as risk factors:
- Smoking
Gangrene and blackening of the ankle are said to be more common in people who smoke because of the damage to the walls of arteries following smoking.
- Vascular diseases as well as diseases of peripheral arteries
The walls of the arteries must be flexible if the walls of the arteries become hard for a variety of reasons, including cholesterol deposition and inflammation of the lining, atherosclerosis, or hardening of the artery wall, is said to have occurred, that in these people, blood flow to an area of the body that is then narrowed is disrupted, resulting in gangrene, blackening, and tissue death.
- Severe trauma accidents
They damage the skin and subcutaneous tissue, especially in people with an underlying disorder, Therefore, a person is much more likely to develop gangrene.
The next factor is drugs, especially injectable drugs, certain drugs, especially drugs that are injected illegally, can cause deep-seated bacterial infections that cause gangrene.
- People with suppressed immune systems
When the immune system is severely deficient, for example in people with AIDS or people receiving extensive chemotherapy or radiotherapy, the body is unable to fight infections, thus exposing it to serious infections and gangrene.
Uncontrolled diabetes People with diabetes may not produce enough insulin in type 1 and type 2 may have insulin resistance in their cells. However, blood sugar rises in both blood levels. Blood sugar rises and accumulates in the blood and causes inflammation of the inner wall of arteries and damage to the inner wall of blood vessels.
And thus removes them from the normal structure and can reduce or cut the blood flow to the damaged lower extremities.
- being overweight
Gaining weight is often associated with diseases that have insulin resistance, such as diabetes and cardiovascular problems, and being overweight alone can harden the walls of the arteries and reduce blood flow in the areas after arterial stenosis, as well as obesity. Which increase the infection and slow down the wound healing.
Symptoms of clinical manifestations
If it is an infectious agent, there may be an unpleasant and foul-smelling discharge from the wound area.
There is also usually a clear line between healthy skin and damaged skin. Severe and sudden pain followed by numbness is often reported by most people.
Thin, shiny skin with asymptomatic skin is usually very common in people with peripheral disorders and diseases.
In cases where the infection is causing the finger to turn black, inflammation and fluid-filled blisters may also be present. An important sign and important point is that whatever the cause of the blackness, it is usually cool when we touch the skin.
Skin discoloration is usually colorless to pale blue-black, even bronze or red. The type of discoloration can depend on the type of underlying disorder that causes the gangrene.
Another vital point is that if the possibility of infection spreading throughout the body is very high, in this case the person experiences a life-threatening condition called sepsis, which can be manifested as septic shock or seizures, high and progressive hypotension and shortness of breath.
What are the types of gangrene?
Gangrenes develop one to two weeks after surgery, and skin lesions in these gangrenes are usually painful.
Fournier gangrene
Gangrene the external genitalia in men and women are called Fournier gangrene, which is usually caused by infections in the genital area, severe pain in the genitals, severe redness and inflammation that is progressive and the groin is also involved and causes blackening and death of these tissues and even death of the person due to infectious shock with hepatic shock.
Internal gangrene may develop in the appendix intestine. It occurs when blood flow to the tissue is reduced or cut off, it is usually accompanied by fever and the person has severe pain in that area and can be fatal if not treated in time.
Gas gangrene commonly occurs on deep muscle tissue. The skin surface may be normal at first. As the disorder progresses, the skin becomes pale, then red, gray, and purple. It also creates a bubble-like appearance on the skin. Damaged skin will crack when pressed. It is also caused by an infection with bacteria that produce gas.
And this gangrene causes tissue death and can be life threatening.
Dry gangrene
The skin at the site of the injury is dry and worn. The skin color can be brown or dark blue to black or completely black. Dry gangrene usually spreads slowly and it usually occurs in people who have arterial disease or diabetes, or in other words, a factor in their blood vessels that has disrupted blood flow. When we talk about blackened finger due to reduced blood flow, we actually mean the same type of gangrene in the fingers.
Wet gangrene
Due to the presence of bacterial infections in the damaged tissues, the appearance of the skin in this gangrene is moist, that means the skin is no longer dry and worn and may be blistered and swollen. This tissue gangrene usually occurs after severe burns, frostbite, severe injuries. People with diabetes usually experience this type of gangrene. People’s toes are usually hurt. This cancer spreads quickly and should be diagnosed and treated more quickly.
Diagnosis
Your team doctor will use the following methods so that they can find out the cause of this complication and finally give a good treatment for it.
Surgery may be needed to diagnose the spread of gangrene in the body. Tissue culture may be needed. For example, cultures of fluid from the blister on the skin are usually needed. Blood tests Changes in white blood cell counts may indicate an infection, and sometimes a blood test to look for bacteria or other infectious agents.
Various imaging, such as CT scans and plain MRI scans, is used to look at internal structures as well as the extent of gangrene spread.
Finally, there is the use of an arteriogram. In this imaging test, which identifies the arteries of a patient with gangrene of the toe, the dye is injected into the patient’s bloodstream and then x-rayed as it flows through the arteries of the foot so that the medical team can identify the narrow artery and the cause of the black finger.
Treatment
- Dead tissue can no longer be saved because it can no longer be revived. The most important step in treatment will be to prevent the progression and spread of gangrene. Usually, depending on the severity of the disease and the patient’s condition, the doctor will use one or more of the following treatment options.
- Surgery to reduce the spread of gangrene.
Timely surgery helps keep more tissue healthy. Improves the patient’s blood supply to better blood flow to most tissues .
Sometimes more than one operation is needed to remove dead tissue. Vascular grafts may be used to repair injuries.
- Antibiotic therapy
Intravenous antibiotics are usually used in cases of widespread gangrene and people with underlying disease, but sometimes oral antibiotics may be prescribed. After surgery, antibiotics may be prescribed to eliminate the need for further surgery and infection. Antibiotics may also usually be combined with oxygen therapy.
- Hyperbaric oxygen therapy: the use of oxygen therapy is an additional method in addition to the process of antibiotic therapy in addition to surgery. Hyperbaric oxygen enables the blood to carry more oxygen. Oxygen-rich blood inhibits the growth of bacteria and improves wound healing.
Other components of a care plan include supportive methods:
- Adjust fluids
- Manage proper food intake as well as prescribe painkillers to relieve discomfort.
Complications
When blackheads occur due to a lack of blood supply, they can lead to sores. Sometimes the sores can become infected, especially when a person with an underlying disease, such as immunodeficiency, diabetes, or overweight, is taking certain medications. The infection causes a life-threatening septic shock.
The doctor may even have to amputate the affected limb to reduce the spread of gangrene.
Prognosis
People with dry gangrene (which is said to be black due to impaired blood supply to the finger or part of the limb) will have a chance to fully recover because they usually have less bacterial infection than other gangrene, but the important thing is that, blackening of the toe following a rapid blood flow disorder should be diagnosed and treated promptly to increase the chances of recovery and prevention of tissue death.
What can we do to prevent gangrene?
- Keep your weight in proportion Obesity and being overweight increase the risk of developing type 2 diabetes.
Increases blood pressure entering the walls of the arteries.
It accelerates atherosclerosis, thus restricting and disrupting blood flow to the arteries.
Also, in these people, the wound usually heals slowly and the risk of wound infection is higher.
- Avoid smoking (any kind of tobacco) because smoking can permanently damage blood vessels.
Beware of frostbite. Freezing skin can die and turn black because frostbite will reduce blood flow to an area.
- If you have diabetes, be sure to follow your diabetes regularly under the supervision of your doctor, and be sure to check your hands and feet daily for signs of infection and inflammation, and control your blood sugar.
