Dizziness after meals may be due to hypertension, transient ischemic attack, cerebral vascular spasm, Meniere’s syndrome, etc., especially in the elderly. When a normal person eats, the body can produce many active substances such as peptide factors, growth hormone inhibitory factors and insulin, which cause vasodilation of abdominal organs, increase blood flow, and a tendency to lower blood pressure and blood sugar throughout the body. For such changes, the body regulates itself, leading to sympathetic excitation, increased secretion of adrenaline, enhanced heart contraction and increased heart rate, which can compensate for the maintenance of normal blood pressure and blood sugar levels. If any of the links are damaged, or if the hormone secretion is insufficient, it will cause discomfort. You can go to the hospital to do some necessary tests such as electrocardiogram, blood lipid, blood sugar, blood routine, etc., to clarify the cause and then actively treat. You should pay attention to a low-fat and low-salt diet, eat more fruits and vegetables, don’t sit up and down, exercise in moderation, and quit smoking and limit alcohol. In modern society, the pace is accelerating and many people feel stressed out. Excessive worry, stress, sadness and emotional burden can also lead to dizziness after meals, and the symptoms will be more intense if the person has an eating disorder. Many antidepressants and medications for allergies can cause dizziness after meals, as well as eating high-fat foods, fried foods and pickled foods can also produce similar symptoms.
