Vomiting may be caused by digestive system diseases, neurological diseases and pregnancy.
1. Digestive system diseases: when the gastrointestinal mucosa is stimulated by inflammation, it will affect the normal digestion and absorption of food, which will cause congestion of the gastrointestinal mucosa, nausea and vomiting and other symptoms, such as acute and chronic inflammation of the gastrointestinal tract, gastric ptosis and chronic obstruction, which will cause reflexive nausea and vomiting through the stimulation of the vagus nerve of the gastrointestinal mucosa.
2. Neurological diseases: when trauma, infection or tumor disease causes brain tissue swelling, or cerebrospinal fluid circulation disorders will cause intracranial pressure increase, intracranial pressure increase will compress the brain tissue, stimulate the brain tissue and thus nausea, vomiting, usually accompanied by headache and other discomforts.
3. Pregnancy: When women of childbearing age become pregnant, it may lead to significant changes in hormone levels in the body, causing a significant increase in the secretion of human chorionic gonadotropin, which may lead to symptoms of vomiting.
Vomiting may also be caused by other reasons. If the vomiting symptoms are severe, you should go to the hospital in time to see a doctor and give standardized treatment after clarifying the cause.
