What are the common diseases associated with vomiting symptoms?

There are several common diseases that can cause vomiting symptoms, mainly including: 1. Digestive system diseases: such as gastritis, gastric ulcer, indigestion, and acute gastroenteritis. These diseases may lead to symptoms such as nausea, dry heaving, and vomiting, often accompanied by abdominal pain and bloating. 2. Central nervous system diseases: such as increased intracranial pressure, meningitis, and brain tumors. These conditions may cause projectile vomiting without significant nausea. 3. Vestibular system diseases: such as Ménière's disease and motion sickness (car sickness, seasickness, airsickness, etc.), which are often accompanied by dizziness and vomiting. 4. Drug-induced vomiting: for example, side effects caused by chemotherapy drugs, iron supplements, and others. 5. Other causes: such as early pregnancy reaction, food poisoning, and psychogenic factors may also lead to vomiting.
