Infections are not uncommon but they will usually clear up before too long. Our bodies are effective at fighting against them, while modern medicines are also effective in defeating them.
Some infections are harder to fight against, though, and can be very serious and even become a threat to our lives. A blood infection, also known as sepsis or septicemia, is often caused when bacteria are able to enter the body.
While the infection in itself poses a risk, what’s really harmful is when the body launches a huge reaction to deal with it. This floods the body with chemicals which affect the blood to dangerous levels. It is potentially fatal if medical help is not sought so it should be taken very seriously indeed.
Symptom #1: Fever
Human beings are warm-blooded animals. This means that we can regulate our own body temperature, adjusting it up or down as and when needed. It will often be adjusted according to the weather and any extra heat that is needed is generated when we metabolize our food. Sometimes, it can also be adjusted to help combat illness.
Pathogens find it difficult to survive in bodies that are too hot. For this reason, our bodies will raise their temperature should a pathogen be detected in our bodies. This is what we know as a fever, and it is a common symptom of many illnesses, including a blood infection.
