Light-headednessis characterised by a sensation of dizziness and may last a fewminutes or longer. The head can also feel weightless and the personmay feel like they are fainting. There are several probable causesfor light-headedness, the most common of which are low bloodpressure, vertigo and stress. Light-headedness happens when the bloodpressure in the head drops.
When aperson eats, their stomach becomes much more active than at othertimes. Active body parts require a lot more blood than non-activebody parts, so blood is redirected to the stomach when digestion isrequired. The more food that needs to be digested, the more bloodneeds to go to the stomach because it needs to work harder. If alarge quantity of food is ingested, so much blood can be redirectedto the stomach that the brain receives less blood than it needs. Thiscauses the feeling of light-headedness.
PreventingLight-headedness after Eating
Payingattention to one's dietary choices is important for a healthylifestyle. This also applies in the case of light-headedness aftereating. Processed foods and foods with a high sugar content tend tocause the stomach to work harder than other types of food. Thistypically affects a person about an hour after the meal. When asubstantial amount of sugar is ingested during one meal, the sugarlevels in the blood spike up and this sudden change can causelight-headedness due to changes in blood pressure.
Eatinguncooked food, eating food to which one has allergies and eatingfoods rich in carbohydrates will make the stomach work harder, as itis forced to digest difficult foods. This can also cause nauseasimply due to the contents of the food. To help preventlight-headedness, eat vegetables and foods rich in protein andcarbohydrates.
Eatingtoo quickly, or moving too soon after eating a meal can causelight-headedness because blood is required in many parts of the bodyat once and there might not be enough of a supply to the brain. Chewfood thoroughly to ease digestion and take a moment to relax aftereating a meal.
