Do you experience lightheadedness after eating a meal? This symptom can be frightening, but, fortunately, in most cases it doesn’t mean you have a serious medical problem. So what causes lightheadedness after eating?
After eating a meal, particularly a large one, more blood flow is shunted to the stomach to aid the digestive process. When more blood flow is directed towards the stomach, the blood pressure drops temporarily – leading to the sensation of lightheadedness. In some cases, fainting can occur, especially if a person gets up too quickly after eating. Lightheadedness after eating is more common in older people, although it can be seen at any age.
Certain conditions can make a person more prone to lightheadedness after eating. One is devouring a large meal. The more food you take in, the more blood flow will be directed to the stomach to aid in the digestive process. Ant time the stomach is distended from too much food, the risk of lightheadedness and fainting increases. It’s not uncommon for an older person to experience lightheadedness or even fainting after eating a meal at a buffet restaurant.
Another fact that can increase the risk of lightheadedness after eating is medications. Certain medications such as blood pressure medications, heart medications, diuretics, and anti-depressants causes fluctuations in blood pressure and volume can lead to the symptom of lightheadedness.
