Mild dizziness after eating can be normal, especially after large or carbohydrate-rich meals, says internal medicine specialist Dr SM Fayaz at Aster Whitefield Hospital. Dizziness can also occur due to dehydration or eating too quickly.
According to a study published in the Brazilian Journal of Otorhinolaryngology, dizziness is a sign of glucose metabolism. However, recurring or prolonged dizziness can be a sign of underlying conditions such as digestive problems, low blood sugar, or sudden changes in blood pressure.
So, to prevent feeling dizzy after eating, try to eat several small meals throughout the day instead of large ones and drink enough water before, during and after eating. Also, take a light walk for at least 30 minutes after meals to aid digestion and maintain blood circulation.
