A study of 20 volunteers conducted at Nagoya University in Japan associated a higher degree of exercise-induced nausea after eating. [1] Lack of hydration during exercise is a well known cause of headache and nausea. [2] Exercising at a heavy rate causes blood flow to be taken away from the stomach, causing nausea. [3]
Gastroparesis (gastro- from Ancient Greek γαστήρ – gaster, "stomach"; and -paresis, πάρεσις – "partial paralysis") is a medical disorder of ineffective neuromuscular contractions (peristalsis) of the stomach, resulting in food and liquid remaining in the stomach for a prolonged period of time.
After describing the known mechanisms of blood glucose regulation, the authors call for more research: The body's normal response to carbohydrate ingestion includes elaboration of an as yet unidentified hormonal (gut) factor from the upper intestine. They say that a glucose tolerance test is appropriate but caution that:
Postprandial somnolence (colloquially known as food coma, after-dinner dip, or "the itis") is a normal state of drowsiness or lassitude following a meal. Postprandial somnolence has two components: a general state of low energy related to activation of the parasympathetic nervous system in response to mass in the gastrointestinal tract , and a ...
The stomach connects to the esophagus above and to the small intestine below. It is intricately related to the pancreas, spleen and liver. The stomach does vary in size but its J shape is constant. [citation needed] The stomach lies in the upper part of the abdomen just below the left rib cage.
The gastrocolic reflex or gastrocolic response is a physiological reflex that controls the motility, or peristalsis, of the gastrointestinal tract following a meal. It involves an increase in motility of the colon consisting primarily of giant migrating contractions, in response to stretch in the stomach following ingestion and byproducts of digestion entering the small intestine.

There is seldom nausea preceding the expulsion, and the undigested food lacks the bitter taste and odour of stomach acid and bile. [2] Symptoms can begin to manifest at any point from the ingestion of the meal to two hours thereafter. [3] However, the more common range is between thirty seconds and one hour after the completion of a meal. [4]
Often the pressure is in the fundus of the stomach, the esophagus or distention of the bowel. It is believed this leads to elevation of the diaphragm, and secondary displacement of the heart. This reduces the ability of the heart to fill and increases the contractility of the heart to maintain homeostasis.
