Bloating, vomiting and dizziness may be caused by acute gastroenteritis, gastrointestinal cold, and indigestion in pregnancy. 1. Acute gastroenteritis: can be caused by bacteria such as E. coli infection, accidental ingestion of poison, eating cold food, etc. The main symptoms are vomiting, dizziness, bloating, fever, headache, diarrhea and so on. It usually develops after meals, and the onset of the disease is more rapid. 2. Gastrointestinal cold: Due to viral infections such as adenovirus and influenza virus, inflammation is produced in the larynx, and then part of the virus is swallowed into the stomach along with saliva, causing digestive reactions such as bloating, vomiting and dizziness. 3. Pregnancy combined with indigestion: After pregnancy, early pregnancy reactions such as dizziness and vomiting may occur, while indigestion may appear as a symptom of bloating. There may be other reasons for bloating, vomiting and dizziness, so it is recommended that you go to the hospital in time, complete the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
