4. Nausea
Most people will suffer from nausea any time there is an issue with their gut. Nausea can be a result of motion sickness, pregnancy, or another condition. It is also one of the leading symptoms of salmonella poisoning. When a person feels nauseous, it is as if they wont to vomit but are not actually doing so.
Most often feeling nauseous will lead to vomiting if the sensation is not corrected quickly. Salmonella poisoning will cause a person to feel nauseous while also causing cramps or other symptoms. This is the effect of the body attempting to expel the harmful bacteria that have been introduced to the stomach environment.
A person who is suffering from extreme nausea may become lethargic and dehydrated. Extreme nausea prevents a person from eating or drinking, and often the mere sight or smell can induce vomiting. Nausea is one symptom of salmonella poisoning to never ignore.
