Sepsis: Definition, Symptoms, Causes, and Treatment

Sepsis is a critical medical condition that occurs when the body's response to an infection spirals out of control, causing widespread inflammation and potential organ failure. This life-threatening condition requires immediate attention, as delayed intervention can lead to severe complications, including death. Recognising sepsis symptoms early and understanding its causes are essential steps in preventing adverse outcomes.

What is Sepsis?

Sepsis is a severe complication that arises when the body's immune system overreacts to an infection. While the immune system typically fights infections effectively, in the case of sepsis, it inadvertently damages the body's own tissues and organs. Sepsis infection can begin with a bacterial, viral, or fungal infection anywhere in the body, including the lungs, urinary tract, skin, or digestive system. If left untreated, it can progress rapidly to septic shock, a life-threatening condition characterised by a dangerous drop in blood pressure.

Symptoms of Sepsis

Recognising the sepsis symptoms early can be life-saving. Common warning signs include:

• High or very low body temperature.
• Rapid heartbeat or breathing.
• Confusion or disorientation.
• Extreme fatigue or weakness.
• Chills and shaking.
• Reduced urine output. If these symptoms occur, particularly after an infection or surgery, seek medical attention immediately.

Causes of Sepsis

The causes of sepsis are typically linked to infections that spread unchecked. These infections may include:

• Pneumonia or lung infections.
• Urinary tract infections.
• Abdominal infections such as appendicitis.
• Skin infections, including cellulitis.
• Bloodstream infections. Understanding these sepsis causes helps in identifying vulnerable individuals and initiating prompt treatment.

Risk Factors for Sepsis

Certain individuals are at a higher risk of developing sepsis infection. Risk factors include:

• Advanced age or infancy, as these groups have weaker immune systems.
• Chronic illnesses such as diabetes, cancer, or kidney disease.
• Recent surgery or hospitalisation.
• Use of immunosuppressant medications.
• Open wounds or injuries that expose the body to infection. By being aware of these risk factors, individuals can take precautions to lower their chances of developing sepsis.

How is Sepsis Diagnosed?

Diagnosing sepsis requires a combination of clinical evaluations and laboratory tests. Doctors typically look for signs of infection along with systemic inflammation. Diagnostic methods include:

• Blood tests to check for signs of infection and organ dysfunction.
• Imaging tests such as X-rays, CT scans, or MRIs to locate the source of infection.
• Urine or sputum cultures to identify the pathogen responsible. Early and accurate diagnosis is crucial for effective sepsis treatment.

Treatment for Sepsis

Sepsis treatment aims to control the infection and support affected organs. Treatment options include:

• Antibiotics: Administered as soon as sepsis is suspected to target the underlying infection.
• Intravenous fluids: Help maintain blood pressure and circulation.
• Oxygen therapy: Provided to ensure adequate oxygen levels in the body.

Advanced cases may require vasopressor medications, dialysis, or even surgery to remove the source of infection. Prompt and aggressive treatment significantly improves outcomes.

Preventing Sepsis

While sepsis cannot always be avoided, preventive measures can greatly reduce its risk:

• Vaccination: Protect against infections like flu and pneumonia.
• Proper wound care: Clean and monitor cuts or injuries to prevent infections.
• Hygiene practices: Regular handwashing and maintaining a clean environment.
• Managing chronic conditions: Keeping illnesses like diabetes under control to reduce susceptibility to infections. These steps can help minimise the risk of sepsis infection, especially in high-risk individuals.

Complications of Sepsis

If sepsis is not treated promptly, it can lead to severe complications, such as:

• Organ failure, particularly in the kidneys, lungs, and liver.
• Septic shock, a critical drop in blood pressure.
• Blood clotting issues, leading to tissue damage or limb loss.
• Long-term effects, such as cognitive or physical impairments. Awareness of these potential outcomes underscores the importance of early detection and treatment.

When to Seek Medical Help

It is vital to seek medical attention if you notice signs of sepsis symptoms after an infection, surgery, or injury. If symptoms like confusion, fever, or rapid breathing arise, consult a healthcare provider immediately. Early intervention can make a critical difference in recovery.
