Once unfriendly bacteria enter your body, your body's immune system tries to fight them off. But oftentimes, your body can't fight the infection naturally, and you need to take antibiotics - medication that kills the bacteria.
Antibiotics are only needed for treating certain infections caused by bacteria, but even some bacterial infections get better without antibiotics. We rely on antibiotics to treat serious, life-threatening conditions such as pneumonia and sepsis, the body's extreme response to an infection.
Most people bounce back in seven to 10 days. "During that time, it takes the immune system three to four days to develop antibodies and fight off pesky germs," says Dr. Hasan.
In response to infection, your immune system springs into action. White blood cells, antibodies, and other mechanisms go to work to rid your body of the foreign invader.
“Some bacterial infections get better on their own, but that's rare,” Dr. Price said. Most of the time, your doctor will prescribe an antibiotic. If that's the case, it's essential to take the entire course—even if you feel better, you need to take all of your medication to make sure you clear the infection.
Even if the infection becomes bacterial, 70% of the time the infection will go away within two weeks without antibiotics. In the event of severe headache, toothache, or face pain or for persisting fevers greater than 102 degrees you should be seen by your health care provider.
As discussed, if your symptoms are caused by a virus (like a cold or flu virus), you won't need antibiotics. But if you have a sore throat due to bacteria — for instance, strep throat or bacterial tonsillitis — you will need antibiotics.
Sepsis happens when an infection you already have triggers a chain reaction throughout your body. Infections that lead to sepsis most often start in the lung, urinary tract, skin, or gastrointestinal tract. Without timely treatment, sepsis can rapidly lead to tissue damage, organ failure, and death.
However, untreated or improperly treated infections can become severe and may cause life threatening complications.
Antibiotics cause side effects, some of which can cause serious problems. These are some common side effects of antibiotics, and why they are bad: Severe diarrhea can cause dehydration. Dizziness can cause falls or accidents when operating machinery.
The bottom line
Amoxicillin is a popular antibiotic that treats bacterial infections. After you start taking your prescription, you may start to feel better in 2 to 3 days, but it may take longer for certain infections. Even if you start feeling better, it's important to finish all of your prescribed doses.
But you need to take the full treatment to kill the disease-causing bacteria. If you don't take an antibiotic as prescribed, you may need to start treatment again later. If you stop taking it, it can also promote the spread of antibiotic-resistant properties among harmful bacteria.
Symptoms in case of acute Bacterial Infections may get resolved spontaneously in a duration of approx. two weeks, without undergoing treatment. However, in chronic cases when the symptoms persist for a longer duration, such as for 10 or more days, there is a need for the consultation with a doctor.
Tests that are frequently performed to help us with the diagnosis of a bacterial infection include a complete blood count and cultures of fluid that we are concerned about. This may include a blood culture, urine culture, or spinal culture (which requires a spinal tap).
One of the first things to do when you have a urinary tract infection is drink plenty of water. That's because drinking water can help flush away the bacteria that's causing your infection, according to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
Staphylococcus aureus (MRSA)
Probably the most famous hospital-acquired infection or 'superbug', MRSA is so-called because of its resistance to the antibiotic methicillin (hence Methicillin Resistant Staphylococcus Aureas).
The best way to get the infection out of the system is by drinking liquids until the urine is clear and the stream is forceful. Drinking at least six tall glasses of water every day helps flush out any harmful bacteria that may be present in the bladder.
Antibacterial ointment
A person can treat a wound with several over-the-counter (OTC) antibacterial ointments, which can help prevent infections. They can also help a wound heal more quickly. One review of 27 animal model studies showed that antibacterial treatments played a positive role in helping wounds heal faster.
