It is possible for some cases of blood poisoning to resolve on their own, especially if the infection is caught early, is not severe and your immune system is able to overcome it. In these cases, your immune system will often clear the bacteria without you knowing it.
However, if the immune system cannot cope, it can lead to more serious conditions such as septic shocks as some of these bacteria can go on to establish an infection in the bloodstream. Examples of such bacteria include:
- Staphylococcus aureus, including MRSA
- Escherichia coli (E. coli)
- Pneumococcal bacteria
- Group A Streptococcus
- Salmonella species
- Pseudomonas aeruginosa
Some common ways in which bacteria enters the bloodstream include:
- dental procedure such as a routine teeth cleaning or through a tooth extraction
- from a surgery or procedure
- an infection spreading from another part of the body into the bloodstream
- via medical devices, particularly in-dwelling catheters and breathing tubes
- through severe injuries or burns
In most cases, treatment with antibiotics is necessary to kill the bacteria that are causing the infection and prevent it from spreading. Without treatment, blood poisoning can quickly become severe and potentially life-threatening. When a bloodstream infection occurs, you’ll likely experience symptoms like:
- fever
- chills
- shaking or shivering
- skin discoloration
If you believe you may have blood poisoning, it is important to seek medical attention as soon as possible to ensure that you receive the appropriate treatment.
