What Are the Common Causes of Vomiting?
Vomiting, also known as Emesis, is a reflex action that forces the contents of the stomach out through the mouth. It can be caused by a variety of factors ranging from mild to severe conditions. One of the most common causes is gastrointestinal irritation or infections, such as gastroenteritis, which is often due to bacteria, viruses, or foodborne illnesses. Motion sickness or seasickness is another frequent cause, triggered by the brain’s response to conflicting sensory signals.
Other causes include pregnancy-related nausea (morning sickness), migraines, or certain medications that irritate the stomach, such as chemotherapy drugs or antibiotics. Food intolerances or allergies can also lead to vomiting, particularly after consuming problematic foods. Overeating or consuming spoiled foods can similarly upset the stomach.
In some cases, vomiting is a symptom of more serious conditions like appendicitis, bowel obstruction, or increased intracranial pressure caused by head injuries or neurological disorders. Psychological factors such as stress, anxiety, or eating disorders like bulimia can also contribute.
