Sepsis is caused by infected wounds or internal infections that get out of control, with bacterial infections being the most common cause. Weakened immune systems, including those from diseases or chemotherapy, can increase the risk. Symptoms include fever, chills, and organ failure, and treatment involves aggressive use of antibiotics and hospitalization.
The primary causes of sepsis are infected wounds and other types of internal infections that get out of control. Some people are at a higher risk of this condition than others, including those with weakened immune systems. Most causes of sepsis are related to bacterial infections, although some cases can be caused by viruses and other problems. Sometimes the causes of sepsis can be behavioral, meaning that leaving an infection untreated for an extended period of time puts a person at much greater risk.
Sepsis is basically a bloodstream infection that occurs when some other infection spreads out of control in the body. This leads to widespread inflammation in many organ systems of the body and blood clots generally begin to form everywhere. There are so many blood clots that form that the body cannot eliminate them in the normal way, and this starts cutting off the blood supply to various parts of the body. Eventually, a person’s organs can begin to fail, with potentially life-threatening consequences.
When a person develops sepsis, they usually start feeling sick all over their body. Many of the symptoms are very similar to the flu. For example, people may develop fever, chills and sweats. They may be delusional and may be too tired to do anything. If nothing is done to treat the cause of sepsis, a person usually sinks into unconsciousness.
There are many reasons for a weakened immune system, including a long-standing infection and various diseases that directly affect the immune response. Regardless of the cause, the condition can lead to sepsis. Older people can also have relatively weak immune systems, as can young children. When someone receives chemotherapy for cancer, they can be especially vulnerable because the treatments have the side effect of weakening the immune system.
One of the most common causes of sepsis is an infected lesion. When someone is seriously injured, it is common for many bacteria to get deep into the body. With so many bacteria present, it can be very difficult for the body to fight them off and the infection can start to spread to a larger area, eventually leading to sepsis. This was particularly common before the advent of antibiotics and meant that many more injuries required amputation as an emergency treatment.
When someone develops a case of sepsis, doctors will typically try to treat the causes of the sepsis directly. This will often involve very aggressive use of antibiotics. Sepsis is very dangerous, so hospitalization is usually mandatory and most people are placed in intensive care due to the severity of the situation.
