How do I know if my vomiting is related to a stomach virus?
Vomiting caused by a stomach virus (viral gastroenteritis) often presents alongside symptoms like diarrhea, fever, abdominal cramps, and fatigue. The condition is usually linked to viruses such as norovirus or rotavirus, and it's commonly transmitted through contaminated food, water, or close contact with infected individuals. The symptoms typically last 1-3 days but can persist longer in some cases. Dehydration is a major risk, so keeping hydrated is crucial. If symptoms worsen or persist beyond a few days, seek medical attention.
2. What’s the difference between vomiting and regurgitation?
Vomiting is an active process where stomach contents are forcefully expelled through the mouth, often accompanied by nausea, retching, and stomach contractions. It involves the digestive system and usually contains partially digested food mixed with stomach acid.
Regurgitation, on the other hand, is passive and involves the backflow of undigested food or liquid from the esophagus into the mouth, without nausea or retching. Common causes include gastroesophageal reflux disease (GERD) and conditions like rumination syndrome. Regurgitation often occurs shortly after eating and can feel like food "coming back up" without effort
3. Why do I vomit after eating certain foods?
Vomiting after eating certain foods may be caused by:
- Food intolerance or allergies: Reactions to specific proteins in foods (e.g., gluten, lactose).
- Food poisoning: Contaminated food causing toxins to irritate the stomach lining.
- GERD or acid reflux: Triggered by fatty, spicy, or acidic foods.
- Gastroparesis: A condition that slows stomach emptying.
- Psychological triggers: Anxiety or sensory aversions to specific foods can also lead to nausea or vomiting.
- If the problem recurs or is severe, consult a healthcare provider to identify the cause.
