It is not possible to run after eating. Because after eating a full meal, the digestion process of food in the stomach requires a lot of blood for digestion. If you run at this time will increase the blood supply to the lower limbs, the strenuous exercise makes part of the blood to the exercise system, which will lead to gastrointestinal ischemia. Insufficient blood supply in the stomach causes gastrointestinal peristalsis too slow to affect digestion, which can easily lead to indigestion, and then there will be stomach discomfort, flatulence and so on. Running after eating, the food in the stomach will also stimulate the gastric mucosa as the body runs, which may cause stomach cramps thus leading to abdominal pain, nausea and vomiting. Long-term this may lead to gastrointestinal diseases such as gastroptosis, gastric bleeding, appendicitis. It is best to take a proper walk half an hour after eating, which can promote gastrointestinal peristalsis, which is beneficial for food digestion and absorption.
