Lightheadedness is a feeling of dizziness, which may be transient, may recur or even be chronic. The feeling is often accompanied by a sensation of weightlessness in the head. One who feels lightheaded, may feel as if the room is spinning and that he is about to faint. What causes lightheadedness? Especially after eating? The most common causes are vertigo, stress and low blood pressure. However, the main reason behind lightheadedness after eating is drop in the amount of blood flowing towards the head.
Lightheadedness After Eating - Causes and Care
After eating, more blood flows towards the stomach to help the process of digestion. As more blood flows towards the digestive system, there is a slight drop in blood pressure resulting in lightheadedness. The more the quantity of food consumed, higher are the chances of experiencing lightheadedness. And that's exactly why one may feel lightheaded particularly after having a large meal. Also, eating food quickly might be the cause. Eating quickly requires the digestive system to quicken the process of digestion. For this, the heart needs to pump more blood towards the stomach, resulting in relatively less blood supply towards the head, causing lightheadedness.
