Internal Medicine

Salmonella infection (salmonellosis) commonly causes the following symptoms:

Fever
Stomach pain or cramps
Diarrhea (sometimes bloody)
Fatigue or weakness
Nausea and vomiting

Symptoms typically appear 6 hours to 6 days after exposure and last 4 to 7 days. Because these signs overlap with many other conditions—like food poisoning from other bacteria, viral gastroenteritis, or IBS—it can be hard to know exactly what's causing your discomfort. Getting clarity early helps you decide whether home care is enough or if you need medical attention. Take a free, instant, online symptom check to better understand your symptoms and confidently navigate your next steps.

Stomach Pain: This can feel like cramping or discomfort in the belly area.
Diarrhea: Loose or watery stools are common and can happen several times a day.
Fatigue: Feeling very tired or weak is also a frequent symptom.

These symptoms can vary in severity. Some people might have mild symptoms, while others can feel very sick.
