Understanding Vomiting
Vomiting (emesis) is a defense mechanism. It is controlled by the brain’s vomiting center, which, upon receiving signals indicating a threat (like toxins or pathogens), triggers the expulsion of stomach contents. This reflex can be involuntary or influenced by external stimuli.
Common Causes of Vomiting
Vomiting can arise from diverse triggers that vary in nature and severity.
Infections
Gastrointestinal infections are prime culprits. Viruses like the norovirus or rotavirus, and bacterial infections like salmonella or E. coli, can induce vomiting as part of the body’s effort to rid itself of harmful pathogens. For more on infections that cause vomiting, visit Causes of Vomiting.
Motion Sickness
Motion sickness arises from mismatched sensory signals. When your inner ear senses motion that your eyes don’t, it results in nausea and vomiting. It commonly affects travelers and can be mitigated with antihistamines or ginger supplements.
Pregnancy
Morning sickness affects about 70% of pregnant women. It results from changes in hormone levels, particularly during the early stages of pregnancy. While often manageable with dietary adjustments, severe cases may require medical attention.
Medications
Certain medications, such as chemotherapy drugs, can induce vomiting. These drugs irritate the stomach lining or affect the brain’s vomiting center directly. Antiemetic medications are often prescribed to manage this side effect.

Serious Health Concerns Signaled by Vomiting
Vomiting can be a sign of serious health issues such as appendicitis, migraines, or brain injuries. Seek immediate medical help if vomiting is accompanied by severe pain, high fever, or symptoms of dehydration. To dive deeper into these conditions, see resources from CDC and Mayo Clinic.
Prevention and Home Remedies

Understanding when vomiting requires expert intervention can prevent severe health consequences.
