Dizziness does not occur with a bad stomach, and the simultaneous occurrence of dizziness with a bad stomach is related to gastrointestinal colds, hypoglycemia, intracranial hypertension and other factors. Bad stomach is mainly caused by slow peristalsis of the stomach, damage to the gastric mucosa, digestive fluid secretion disorders and other factors. The main manifestations of the patient when the stomach is bad are stomach bloating, stomach pain, acid reflux, belching, nausea, vomiting, indigestion and other symptoms, and some of them are implicated in the intestinal system, causing abdominal pain, bloating and diarrhea, but they will not have cardiovascular and cerebral vascular effects. When the human body has a gastrointestinal cold, the cold virus will not only affect the digestive system, but also affect the respiratory system. When the human body suffers from ischemia and hypoxia, some people will suffer from dizziness and headache. Hypoglycemia occurs when the glucose in the blood is unable to provide energy to the vital organs in the body, so there is a lack of blood and oxygen. During a hypoglycemic episode, the body may experience nausea, vomiting, dizziness, and other symptoms. High pressure in the body causes damage to the nerves in the brain, resulting in dizziness. When the cerebral nerves are damaged, the vegetative nerves of the body are also affected, so most people have stomach symptoms, and the stomach symptoms caused by intracranial hypertension are mainly characterized by projectile vomiting.
