While the number and severity of symptoms vary among individuals, repetitive regurgitation of undigested food (known as rumination) after the start of a meal is always present. [ 2 ] [ 3 ] In some individuals, the regurgitation is small, occurring over a long period of time following ingestion, and can be rechewed and swallowed.
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 ...
Signs and symptoms include early satiety, nausea, vomiting, extreme "stabbing" postprandial abdominal pain (due to both the duodenal compression and the compensatory reversed peristalsis), abdominal distention/distortion, burping, external hypersensitivity or tenderness of the abdominal area, reflux, and heartburn. [5]
If there is no change of symptoms after 2 to 4 weeks of avoidance of the protein then food allergy is unlikely to be the cause and other causes such as food intolerance should be investigated. [ 21 ] [ 22 ] [ 23 ] This method of exclusion-challenge testing is the premise by which the Elimination Diet is built upon, as explained in the sections ...
Symptoms may include upper abdominal fullness, heartburn, nausea, belching, or upper abdominal pain. [3] People may also experience feeling full earlier than expected when eating. [4] Indigestion is relatively common, affecting 20% of people at some point during their life, and is frequently caused by gastroesophageal reflux disease (GERD) or ...
There is some evidence of the existence of a so-called "adrenergic postprandial syndrome": the blood glucose level is normal, and the symptoms are caused through autonomic adrenergic response. [6] Often, this syndrome is associated with emotional distress and anxious behaviour of the patient.
Fructose malabsorption, formerly named dietary fructose intolerance (DFI), is a digestive disorder [1] in which absorption of fructose is impaired by deficient fructose carriers in the small intestine's enterocytes. This results in an increased concentration of fructose. Intolerance to fructose was first identified and reported in 1956. [2]
While GI disease is one of the major symptoms of GSE that are characterized by increased levels of IgA/IgG to food proteins, [62] many conditions like chronic constipation and irritable bowel disease persist after GF diet. Some of this may be due to persistent undetected food allergies, increased sensitivity of the damaged gut, or problems ...
