What kind of doctor treats Campylobacter Infection?
Your primary care doctor usually treats this first. Campylobacter is a common bacterial stomach illness. For severe cases, you may see a gastroenterologist, a doctor who treats the digestive system, or an infectious disease doctor. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is Campylobacter infection?
Campylobacter infection is a common foodborne illness, meaning an illness you get from eating or drinking something contaminated. It comes from Campylobacter bacteria, germs that live in the guts of many animals. The illness is called campylobacteriosis. It mostly harms the small intestine. It is a type of bacterial food poisoning.
Most people get it from raw or undercooked poultry, especially chicken. One drop of juice from raw chicken can hold enough germs to make you sick. You can also get it from other dirty foods, untreated water, raw milk, or by touching animals that carry it, even pets.
Symptoms
Symptoms usually start 2 to 5 days after you swallow the germs. They usually end within 7 days. Most people have:
- Diarrhea (loose, watery stools) that can be bloody.
- Fever.
- Stomach cramps.
Some people also have nausea (feeling sick to the stomach), vomiting, or belly pain. Most people fully recover within about a week.
Causes and who gets it
The germs spread through dirty food and water and through contact with animals. The bacteria can live in the guts of many animals, including poultry and pets, without making them sick. People get infected by eating raw or undercooked poultry, using a knife or cutting board that touched raw poultry on other foods, drinking untreated water, or touching animals or their poop.
Anyone can get it. The risk is higher in children under 5, adults 65 and older, people with weak immune systems, people who work with animals, and travelers. Infections are more common in summer than in winter.
How doctors diagnose it
Doctors find it with a lab test on a stool (poop) sample. A stool culture grows the germs so they can be named. A stool PCR test looks for the germs' genes. Other tests may include a complete blood count, which is a blood test, or stool testing for white blood cells.
Treatment
Most people get better without antibiotics, medicines that kill bacteria. The main goal is to stay hydrated, or keep enough fluid in your body. Drink extra fluids while the diarrhea lasts. Eat small meals during the day instead of three big ones.
Severe symptoms may improve with antibiotics. If the immune system is not working well, the infection can spread to the heart or brain. People who take diuretics (water pills) may need a break from them, but never stop a medicine without first talking to your doctor.
When to see a doctor
Seek care if diarrhea or vomiting lasts more than 2 days, if there is blood in your stool or pee, or if you have a fever above 102 degrees F. Also get care for signs of dehydration (not enough fluid in the body): little or no pee, very dark pee, extreme thirst, or a dry mouth. Seek care for weakness or tingling. These can be early signs of Guillain-Barre syndrome, a rare nerve problem that can cause paralysis. People with it need to be in the hospital. Also see a doctor for severe belly pain or diarrhea that does not improve in a week. Call 911 right away if you faint, feel confused, or have trouble breathing.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either can treat stomach illness and check on you during recovery. If you need a specialist, they can set up that referral and manage your long-term care.
Common questions
How do I get Campylobacter?
Most often by eating raw or undercooked poultry. You can also get it from untreated water, raw milk, dirty produce, or touching animals that carry it. It takes very few germs to cause an infection.
How long does it last?
Most people fully recover within about a week. Symptoms usually start 2 to 5 days after you swallow the bacteria.
Do I need antibiotics?
Usually not. Most people get better without them. Severe symptoms may improve with antibiotics.
Can it cause long-term problems?
Sometimes. It can lead to irritable bowel syndrome (a long-term gut problem), arthritis, or Guillain-Barre syndrome. Guillain-Barre is rare. The immune system attacks the nerves. It causes weakness and sometimes paralysis. People with it need to be in the hospital.
How can I prevent it?
Cook poultry all the way through. Wash your hands with soap and water. Use a separate cutting board for raw meat. Drink treated water and pasteurized milk. Be careful when preparing raw meat and around pets.
