Blood Poisoning

What is blood poisoning?

Blood poisoning has nothing to do with poison. It is an early stage of sepsis. Sepsis is a life-threatening infection in your bloodstream. Untreated blood poisoning can cause sepsis. Sepsis can cause organ failure and death. Sepsis is unpredictable and aggressive. It progresses rapidly.

Bacteria can enter the bloodstream a number of ways, including through wounds. This includes burns, cuts, and scrapes. Bacteria can come from something as simple as a sinus infection, too. Any of these situations can lead to blood poisoning.

Blood poisoning and sepsis require immediate treatment. This is to prevent sepsis from infecting major organs, like the lungs, kidneys, and heart.

Anyone can get blood poisoning and sepsis, but the risk is higher for:

  • Infants and young children (especially under 1 year of age).
  • Older people (65 years of age or older).
  • People who have a weakened immune system.
  • People who have chronic medical conditions. This includes diabetes, cancer, and AIDS.
  • People who have just had surgery.

Symptoms of blood poisoning

The symptoms of blood poisoning are similar to symptoms of a cold or the flu and may include:

  • Chills, shivering
  • Sudden fever (moderate to high temperature)
  • Fast heartbeat
  • Rapid breathing
  • Heart palpitations (heart skips a beat or seems to flutter)
  • Low energy (more in children)
  • Irritability (more in children)

Additional symptoms that indicate sepsis, include:

  • Confusion or disorientation
  • Extreme pain or discomfort
  • Shortness of breath
  • Clammy or sweaty skin

If you recently had surgery or a wound that could be infected, take these symptoms seriously. They could signal blood poisoning. If you have any of these symptoms, call your doctor immediately.

What causes blood poisoning?

Blood poisoning is caused by bacteria entering your bloodstream. This infects your blood. Bacteria can enter your bloodstream in a number of ways. This includes daily activities, such as brushing your teeth too vigorously. A simple dental cleaning can cause bacteria to enter your bloodstream. This is true if you have certain risk factors. Risk factors include prior knee or hip replacement. It is difficult for your body to clear bacteria around prosthetic devices. In this case, your dentist will have you take antibiotics before your appointment to prevent infection. Bacteria can enter your bloodstream through a scraped knee or other wound. Even a sinus infection can cause bacteria to enter your bloodstream.

Your immune system will eliminate small amounts of bacteria. When this does not happen, it can cause blood poisoning. Too many bacteria can enter your bloodstream at once. Your immune system cannot keep up. This causes blood poisoning.

How is blood poisoning diagnosed?

Blood poisoning is diagnosed by examining a blood sample to find bacteria in the blood. Also, doctors check the number of white blood cells in the sample. If you suspect you have blood poisoning, call your doctor right away. Your doctor will examine you and order blood tests, if necessary.

If bacteria are in your blood, your doctor will identify the type of bacteria. If you have a cut or other wound on your body, your doctor may swab that area to collect bacteria.

Can blood poisoning be prevented or avoided?

To lower your risk of blood poisoning:

  • Take care of cuts and open wounds. Don’t let them become infected. Keep it clean. Treat it with antiseptic medicine or as directed by your doctor.
  • Get flu and pneumonia vaccines.
  • Don’t ignore a toothache. A tooth infection can cause blood poisoning. See your dentist before it becomes a bigger problem.
  • See your doctor for sinus and ear infections.
  • Be aware that infection can occur following surgery or a medical treatment.

Blood poisoning treatment

The treatment of blood poisoning often involves admission to a hospital’s intensive care unit (ICU) for those who are very sick. This is so that your doctor can give you antibiotics and other medicines intravenously and closely monitor your organ systems. Fast treatment is important. Blood poisoning can become sepsis. Sepsis is life-threatening. It damages vital organs. When blood poisoning is caught early and didn’t do any serious damage, you can then be switched to oral antibiotics that you can take at home. These are usually in pill form.

Living with blood poisoning

Many people fully recover from blood poisoning. However, blood poisoning is serious and can lead to sepsis. When you have sepsis, damage to major organs may be irreversible. For example, kidney damage could lead to lifelong dialysis. Once you have had blood poisoning, you are at higher risk for developing infections in the future.

Questions to ask your doctor

  • Am I in a high-risk group for blood poisoning?
  • Do all prosthetic devices increase your risk of infection?
  • Why are flu and pneumonia vaccines important in preventing blood poisoning?
  • Are certain blood types at a higher risk for blood poisoning?
