One of the most common symptoms of salmonella is vomiting. The main reason for this is because this bacteria affects the digestive symptoms. Vomiting profusely can cause a person to lose important fluids. When these fluids are lost, a person may become dehydrated. Dehydration can have serious consequences especially in small children and people who have compromised immune systems.
For this reason, if you suspect a young child or a person who is elderly or those who have illnesses such as HIV or cancer, has salmonella poisoning it is important to take them to the doctor right away. It is also important to make sure that you give them plenty of fluids in order to help them to rehydrate. Noticing this symptom early on is important so that the person does not get totally dehydrated, which can cause them to become even sicker and can cause even more complications.
