Dizziness when getting up is caused by positional vertigo, but some digestive diseases can also cause similar symptoms.1. Ischemia or anemia in the brain can also cause dizziness. Positional vertigo is dizziness that occurs when the body changes position and may be caused by excessive mental stress. Infections, especially otitis media, can also cause dizziness.2 Digestive system diseases, such as gastritis and gastric ulcer, can lead to chronic anemia, which can lead to insufficient blood supply to the brain, thus causing positional vertigo.3 In addition to the effects of gastric ulcer, local vascular insufficiency or the formation of blood clots, which can cause atherosclerotic plaques, can lead to insufficient blood supply to the brain. Heart disease, especially insufficient myocardial ejection, can also cause similar symptoms.
