There are several possible reasons for dizziness during meals: 1. Consider that the patient’s blood is high in fat and viscous. When the patient eats greasy food, it is easy to cause the blood to become more viscous, thus causing a lack of blood supply to the brain, and the patient will show dizziness. 2, the patient’s dizziness during meals may also be caused by elevated blood pressure, which can be clarified by measuring blood pressure. 3, the patient’s dizziness during meals cannot be ruled out to be caused by cervical spondylosis, because if the patient maintains a posture for a long time during meals, when the vertebral artery is compressed by the cervical intervertebral disc, it will also cause the patient to become dizzy. 4, dizziness during meals is often seen in the elderly and frail, suffering from chronic diseases or patients with serious heart problems, because after eating will lead to more concentration of blood to the digestive tract, helping the digestive tract to digest food and promote gastrointestinal peristalsis, resulting in a reduction of blood supply to the heart and brain, the patient will experience symptoms of dizziness.
