Understanding Salmonella: A Guide to its 10 Symptoms

3. Vomiting

Vomiting occurs shortly after nausea begins, as the body works to expel the invading bacteria, due in part to the increase in stomach acid prompted by the infection. Doctors usually advise people to let vomiting run its course rather than suppressing it with medication. The symptom is a natural reaction that can reduce the duration and severity of salmonellosis if the body successfully expels bacteria before the infection reaches the intestines. However, repeated vomiting and diarrhea can lead to dehydration. If these symptoms persist or dizziness or lightheadedness develop, it is important to seek medical care.
