2. Vomiting (Forceful Stomach Emptying)
Vomiting is one of the body’s defense mechanisms against foodborne pathogens and toxins. When the digestive system detects a threat, such as harmful bacteria or irritants, it triggers the vomiting reflex to expel these substances. Vomiting can provide temporary relief from nausea but may cause dehydration. It can be a distressing symptom, often accompanied by retching and abdominal contractions.
