What kind of doctor treats Salmonella Enterocolitis?
A primary care doctor, such as a family medicine or internal medicine doctor, usually treats Salmonella enterocolitis. Severe cases may be referred to an infectious disease specialist. 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 it is
Salmonella enterocolitis is an infection of the small and large intestines caused by Salmonella bacteria, germs often found in contaminated food. The infection inflames the gut lining, meaning it becomes swollen and irritated, leading to diarrhea and stomach cramps. Most people recover at home within a few days to a week.
Symptoms
Symptoms usually start within six hours to six days after eating contaminated food or water. The most common signs are watery diarrhea, stomach cramps, fever, nausea, and vomiting. Most healthy people get better in about four to seven days. If diarrhea is severe or lasts more than a few days, the body can lose too much water.
Causes and who gets it
Salmonella bacteria live in the intestines of animals such as chickens, cows, and reptiles. People usually get sick by eating raw or undercooked poultry or eggs, drinking unpasteurized milk, or eating food that touched raw meat. Babies, older adults, pregnant people, and those with weakened immune systems face a higher chance of serious illness.
How doctors diagnose it
A doctor will ask about symptoms and recent meals. The main test is a stool culture, in which a lab checks a bowel movement sample for Salmonella. Blood tests may be ordered if the illness seems severe.
Treatment
For most people, treatment focuses on rest and drinking plenty of fluids. Oral rehydration solutions can help prevent dehydration. Antibiotics are usually not needed for mild cases and are reserved for people who are very sick or at high risk. Doctors avoid most anti-diarrhea medicines because they can prolong the illness.
When to see a doctor
Call a doctor if diarrhea lasts more than a few days, if there is blood in the stool, or if a fever is high. Signs of dehydration, such as very dark urine, dizziness when standing, or a dry mouth, also need medical attention.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance for visits. A concierge doctor usually charges more and often works alongside insurance. Either type can handle most cases directly and would refer severe cases to a hospital or specialist.
Common questions
Can Salmonella go away without antibiotics?
Yes, in most healthy people the infection clears on its own within about a week. Antibiotics are saved for severe cases or for people at higher risk of complications. A doctor decides what treatment is best for each person.
How long am I contagious?
A person with Salmonella can spread the bacteria in their stool for days to weeks after symptoms end. Washing hands well with soap after using the bathroom and before cooking helps prevent spreading it to others.
What foods most often cause Salmonella?
Raw or undercooked chicken and turkey, raw or runny eggs, unpasteurized milk, and raw sprouts are common sources. Pet reptiles and baby chicks can also carry the bacteria and pass it to people.
When should someone go to the emergency room?
Go to the emergency room for signs of severe dehydration, such as confusion or fainting. Also go if there is blood in the stool or a very high fever. These signs suggest the infection may be serious and needs prompt care.
