Gangrene

Gangrene is a serious condition in which body tissue dies because of reduced blood circulation, infection, or a combination of both.

It most commonly affects the lower extremities and skin when blood supply to the tissues is reduced. Gangrene can occur in the feet, toes, fingers, muscles and, in some cases, internal organs.

Gangrene requires prompt medical attention, particularly when infection is involved, because some forms can progress rapidly and may lead to serious complications.

What Is Gangrene?

Gangrene occurs when an area of body tissue loses its blood supply or becomes severely infected, resulting in tissue death.

It can develop in different forms. The main types described by their appearance and underlying process are:

1. Dry gangrene
2. Wet gangrene
3. Gas gangrene

Each type can have different causes, symptoms and progression.

Types of Gangrene

1. Dry Gangrene

Dry gangrene is also known as mummification.

It is commonly associated with conditions that reduce blood circulation, including diabetes and peripheral arterial disease. It generally progresses more slowly than infected forms of gangrene and is not primarily caused by bacterial infection.

The affected tissue may become:

• Dry
• Scaly
• Shrunken
• Dark or discolored

A clear demarcation line may develop between viable and non-viable tissue.

In some cases, the dead tissue may eventually separate from healthy tissue, a process known as autoamputation.

Although dry gangrene may progress more slowly than wet or gas gangrene, it still requires medical assessment because the underlying loss of blood supply can be serious and the condition may progress.

2. Wet Gangrene

Wet gangrene, also called moist or bacterial gangrene, occurs when tissue death is associated with infection.

The affected area may become swollen and develop:

• Blisters
• Ulceration
• Pus or infected discharge
• Foul or offensive smell
• Dark or bluish discoloration

Wet gangrene can progress rapidly. Infection may spread into the bloodstream and cause sepsis, making prompt medical treatment extremely important.

3. Gas Gangrene

Gas gangrene is a serious bacterial infection of tissues, commonly associated with Clostridium bacteria.

These bacteria can produce toxins and gas within the affected tissues, causing rapid tissue destruction.

Gas gangrene can progress quickly and may lead to severe infection, sepsis and shock. It is a medical emergency requiring immediate hospital treatment.

Causes of Gangrene

Gangrene can occur when the blood supply to a particular area of the body is reduced or when tissue becomes severely infected.

Possible causes and contributing factors include:

• Vascular problems such as diabetes and peripheral arterial disease
• Low blood pressure or hypotension
• Severe burns and scalds
• Frostbite
• Raynaud’s disease
• Injury to tissues
• Embolism or blockage of a blood vessel
• Smoking
• Obesity
• Excessive alcohol intake, which may contribute to nerve damage
• Intravenous drug use

Poor blood circulation can reduce the amount of oxygen reaching tissues and make it difficult for damaged tissue to heal.

Risk Factors for Gangrene

Some conditions and circumstances can increase the risk of developing gangrene.

Diabetes

Diabetes can affect blood vessels and nerves and may reduce circulation and the ability to notice injuries, particularly in the feet.

Peripheral Arterial Disease

Reduced blood flow through the arteries can deprive tissues of oxygen and increase the risk of tissue damage.

Smoking

Smoking can adversely affect blood circulation and increase the risk of vascular problems.

Severe Injury or Burns

Major injuries, burns and scalds can damage tissue and interfere with normal blood circulation.

Obesity

Obesity may contribute to health conditions that increase the risk of poor circulation and tissue damage.

Symptoms of Gangrene

The symptoms can vary depending on the type and location of gangrene.

Common signs and symptoms may include:

• Blackish or bluish discoloration of the affected skin
• Inflammation or swelling
• Foul or offensive smell from affected tissue, particularly in wet or gas gangrene
• Dry, scaly and shrunken skin in dry gangrene
• A clear line between viable and non-viable tissue in dry gangrene
• Fever and chills
• Blisters containing brown-red fluid
• Weakness
• Numbness of the affected area
• Symptoms associated with diabetic neuropathy
• Crepitus, or a crackling sensation caused by gas within tissues, particularly in gas gangrene

A rapidly changing skin color, severe pain or numbness, foul-smelling discharge, blisters, fever or other signs of infection should not be ignored.

Diagnosis of Gangrene

Diagnosis may involve physical examination along with laboratory tests and imaging, depending on the suspected type and cause.

Blood Tests

Blood tests may help identify signs of infection or other abnormalities.

Fluid and Tissue Culture

Fluid or tissue from an infected area may be examined to identify the microorganism responsible for the infection.

Blood Culture

Blood cultures may be performed when a bloodstream infection is suspected.

MRI or CT Scan

MRI or CT imaging may be used to evaluate affected tissues and help identify the extent of tissue damage or problems involving blood vessels.

Complications of Gangrene

Gangrene can cause serious complications, particularly when infection is present.

Possible complications include:

• Spread of infection
• Sepsis
• Severe tissue destruction
• Shock
• Loss of the affected tissue or limb

Wet gangrene and gas gangrene can progress rapidly and require urgent medical treatment.

Precautions and General Care

People at risk of gangrene should take care of their circulation and protect the skin from injury.

Helpful precautions include:

• Control diabetes and other underlying health conditions with appropriate medical care.
• Avoid smoking.
• Take care of wounds and seek medical attention for wounds that do not heal.
• Protect the hands and feet from burns, frostbite and injuries.
• Pay attention to changes in skin color, temperature or sensation.
• Seek prompt medical attention for signs of infection.
• People with reduced sensation due to diabetic neuropathy should regularly check their feet for injuries or skin changes.

Frequently Asked Questions About Gangrene

Can gangrene cause numbness in the affected area?

Yes. Gangrene can damage nerves and may cause loss of sensation or numbness in the affected tissue. Numbness, especially when accompanied by skin discoloration or a wound, requires urgent medical assessment.

Can gangrene cause a bad smell?

Yes. Wet or infected gangrene may produce foul-smelling discharge or an unpleasant odor from the affected tissue. This can indicate serious infection and requires prompt medical treatment.

Can gangrene spread to other parts of the body?

Yes. In some cases, especially when infection is involved, gangrene can spread quickly into surrounding tissues and may lead to a severe systemic infection such as sepsis.

Can a wound turn into gangrene?

Yes. A severe wound can develop gangrene if its blood supply is significantly reduced or if the damaged tissue becomes infected. Wounds with increasing pain, swelling, discoloration, discharge or foul odor should be assessed urgently.

Can gangrene affect the toes or feet?

Yes. The toes and feet are common sites, particularly in people with conditions that affect blood circulation or nerve function. Any wound or area of discoloration on the foot that is worsening should receive prompt medical attention.

What should I do if I suspect gangrene?

Gangrene requires urgent medical evaluation. Do not wait for the tissue changes to improve on their own or attempt to remove damaged tissue yourself. Prompt treatment may be needed to control infection, restore blood flow and remove dead tissue.
