Sepsis and Bacterial Infections

Bacteria are microscopic single-cell microorganisms (microbes) that are all around us. Most are harmless, and many are helpful. For example, bacteria in your intestines (gut) help break down the food you eat so your body can digest it. However, some types of bacteria can cause bacterial infections, which in turn can cause sepsis.

Sepsis, which was often called blood poisoning, is the body’s life-threatening response to infection. Like strokes or heart attacks, sepsis is a medical emergency that requires rapid diagnosis and treatment.

More About Bacterial Infections

Examples

Bacteria must enter your body for them to cause an infection. So you can get a bacterial infection through an opening in your skin, such as a cut, a bug bite, or a surgical wound. Bacteria can also enter your body through your airway and cause infections like bacterial pneumonia. Other types of bacterial infections include urinary tract infections (including bladder and kidney infections) and dental abscesses, as well as infections caused by MRSA, Group B Streptococcus, and C. Difficile. Infections can also occur in open wounds, such as pressure ulcers (bed sores). Pressure ulcers are caused by constant pressure on the skin for extended periods or rubbing. For example, a senior who is bedridden could develop sores on the coccyx (tailbone) area, elbows, heels, or anywhere else where there is constant contact with a bed or adapted “easy chair.”

The name of one type of infection, septic arthritis, may be confusing to some people because it is not sepsis, despite its name. Septic arthritis is an infection in the joint fluid. However, this type of infection can also lead to sepsis. It can be caused by bacteria, as well as other microbes.

Sometimes bacterial infections are “secondary infections.” For example, if you contract COVID-19 – a virus – your body is in a weakened state and could also develop bacterial pneumonia. You would then be fighting both a viral infection and a bacterial one.

Symptoms

Bacterial infections present in many ways, depending on the part of the body affected. If you have bacterial pneumonia, you may experience

  • Fever
  • Cough, with phlegm
  • Shortness of breath
  • Sweating
  • Shaking chills
  • Headache
  • Muscle pain
  • Fatigue
  • Chest pain with breathing

If you have a urinary tract infection, you may have some of these symptoms:

  • Sudden and extreme urges to void (pass urine)
  • Frequent urges to void
  • Burning, irritation, or pain as you void
  • A feeling of not emptying your bladder completely
  • A feeling of pressure in your abdomen or lower back
  • Thick or cloudy urine – it may contain blood
  • Fever

The common element with most bacterial infections are:

  • Fever
  • Chills
  • Pain or discomfort in the affected area

But if the infection is in a joint, that joint and the surrounding area will likely hurt; if you have a sinus infection, you will probably have a headache and foul nasal discharge, and so on.

Prevention

Not all infections can be prevented, but the chances of spreading these infections can be greatly reduced by following these tips:

  • Wash your hands often, particularly if you are in a healthcare facility.
  • Keep wounds clean and covered.
  • Avoid sharing personal items, such as razors.
  • Eat a healthy diet. Malnutrition, not consuming enough nutrients for your needs, can lower your body’s ability to fight
Treatment

Most often, treatment for a bacterial infection is with antibiotics. They could be taken orally (by pill, liquid, or capsule), injection, drops, topical (cream or ointment), or intravenously (by IV). The treatment may be very short, or it could go as long as several weeks, depending on the type of infection and how it reacts to the antibiotics. Sometimes, the infection will not go away, and your doctor may have to try a different type of antibiotic.

Celebrities

Actress Ashley Park was treated for tonsillitis that progressed to sepsis. Other celebrities, like singer Chris Young and radio personality Casey Kasem, developed wound infections. Learn about more celebrities who had sepsis here.

In October 2022, I was a happily married mother of three young children, all under the age of 10. At the time, I was in good health and actively engaged in various family activities. Although I was feeling slightly unwell, I did not consider it a cause for concern. The next thing I remember is waking up 12 days later in the ICU, where I was informed of my diagnosis: sepsis caused by Haemophilus influenzae. I had developed unexpected abscesses on my legs and experienced significant cognitive impairment due to a brain infection. I later learned that my husband had ... Read Full Story

I am a healthy, active 50 year old. Next Wednesday will be the one year anniversary of waking up with pain in my knee like I slammed it into a wall overnight. I rode my bike easily to an exercise class at 6 am but by 8 AM my knee was a giant ball and I couldn’t put any weight on the leg. A first visit to the ER didn’t show signs of fever or redness so I was sent home at noon with crutches and instructions to return if fever . By 3 pm the fever had set in ... Read Full Story

My sepsis story occurred while hiking in the Himalayas of Nepal in October 2023. However, it began a month before when I had a bad treadmill accident in which my foot fell and was trapped between the wall and my treadmill belt for a solid 30 seconds. This incident peeled my skin back, exposing the ligament. This wound had mostly healed by the time I started my trek in Nepal, but unfortunately reopened during my days of hiking through the villages. After a few days, I was diagnosed with a Staph infection at the injury site and given antibiotics for ... Read Full Story

On 12/15/2021 I began my journey through sepsis. Let me go back about a week prior to that date I told my husband I felt like I was dying inside. I went to see my doctor on 12/9/2021. For pain in my lower back, shooting around to my left hip and down my leg. She listened to my lungs, took my vitals and diagnosed me with a slipped disc. No X-rays, no blood work, just prescribed pain meds and steroids. Well on the 15th I tried to get up and use the restroom. But when I tried to stand my ... Read Full Story
