Causes and Risk Factors for Sepsis

Overview

Sepsis is caused by an infection, which can be bacterial, viral, or fungal. Some common infections that can lead to sepsis include urinary tract infections, lung infections like pneumonia, infections of the appendix or abdominal cavity, and gallbladder or liver infections. Infections can also occur when bacteria enter the body through catheter sites, wounds, or burns. It's important to note that most people who develop sepsis already have an underlying health condition. According to the Centers for Disease Control and Prevention (CDC), about one-quarter to one-third of individuals with sepsis had visited a healthcare professional in the week before their hospitalization.

Non-modifiable Risk Factors (Risk Factors You Can't Change)

Sepsis is a serious condition that occurs when the body's response to an infection causes widespread inflammation. Non-modifiable risk factors (those that cannot be altered or changed) for sepsis include:

Age: Increasing age is a significant non-modifiable risk factor for sepsis. As people get older, their immune system may weaken, making them more susceptible to infections like sepsis.
Sex assigned at birth: While sepsis can affect anyone regardless of sex assigned at birth, some studies have found that males may have a slightly higher risk of developing sepsis compared to females. However, the reasons for this difference are not fully understood.
Genetics: Genetic factors can play a role in determining an individual's susceptibility to sepsis. Having a positive family history of sepsis or other related infections may increase the risk.
Race or ethnicity: Certain racial or ethnic groups may have an increased susceptibility to sepsis. For example, studies have shown that individuals from Indigenous, Native American, Aboriginal, or Black backgrounds may be at higher risk for developing severe sepsis compared to white individuals. However, it's important to note that the reasons for these disparities are complex and multifactorial.

It's crucial to remember that while these non-modifiable risk factors can contribute to an individual's risk of developing sepsis, they do not guarantee that someone will develop the condition. Many other factors, including modifiable risk factors and individual circumstances, also play a role in determining an individual's overall risk of sepsis.

Modifiable Risk Factors (Factors You May Be Able to Change)

While some risk factors for sepsis cannot be changed, there are certain modifiable risk factors that individuals can address to reduce their risk. Here are some of them:

Chronic diseases: Having chronic diseases such as hypertension, cancer, HIV/AIDS, diabetes mellitus, chronic kidney diseases, cardiovascular diseases, coronary artery diseases, obesity, and liver diseases can increase the risk of developing sepsis. Managing these conditions through medication, lifestyle changes, and regular medical check-ups can help reduce the risk.
Infection prevention: Infections can lead to sepsis, so taking steps to prevent infections is crucial. This includes practicing good hygiene by washing hands regularly with soap and water, using hand sanitizers when soap is not available, and keeping wounds clean and covered.
Vaccinations: Keeping up to date with recommended vaccinations can help prevent infections that may lead to sepsis. Vaccines for diseases such as influenza, pneumonia, and meningitis can significantly reduce the risk of developing sepsis.
Smoking cessation: Smoking weakens the immune system and increases the risk of infections. Quitting smoking can improve overall health and lower the chances of developing sepsis.
Alcohol moderation: Too much alcohol use can impair the immune system and make individuals more susceptible to infections. Limiting alcohol intake or seeking help for alcohol abuse can lower the risk of sepsis.

It's important to note that while these modifiable risk factors can be addressed, they do not guarantee complete prevention of sepsis. However, by making these positive changes in lifestyle and managing chronic conditions effectively, individuals can significantly reduce their risk of developing sepsis.

Reducing Risks

To prevent or reduce the chances of getting sepsis, there are several actions that a person can take:

Practice good hand hygiene: Washing your hands regularly with soap and water can help prevent the spread of infections that may lead to sepsis.
Stay up to date on recommended vaccines: Vaccinations can help prevent certain infections that can cause sepsis. Talk to your healthcare professional about which vaccines are recommended for you.
Keep cuts clean and covered: If you have any cuts or wounds, it's important to keep them clean and covered until they have fully healed. This helps prevent bacteria from entering the body and causing an infection.
Monitor and treat current health conditions: If you have any underlying health conditions, such as chronic lung disease or a weakened immune system, it's important to monitor them closely and follow your healthcare professional's recommendations for treatment. Managing these conditions effectively can help reduce the risk of developing sepsis.
Be aware of the signs and symptoms of sepsis: Knowing the signs and symptoms of sepsis is crucial in seeking prompt medical attention. Common signs include fever, rapid heart rate, difficulty breathing, extreme pain or discomfort, and confusion. If you experience any of these symptoms, it's important to seek immediate medical attention.
Seek urgent medical attention if sepsis occurs: Sepsis is a medical emergency that requires immediate treatment. If you suspect that you or someone you know may have sepsis, it's important to seek urgent medical attention to prevent the condition from progressing.

While these actions can help reduce the risk of developing sepsis, it's always a good idea to consult with your healthcare professional for personalized advice and guidance. They can provide specific recommendations based on your individual health status and needs.
