An ulcer in the stomach is a gastric ulcer; an ulcer in the duodenum is a duodenal ulcer.PerineumThe area of the toàn thân between the anus & the vulva in females, and between the anus và the scrotum in males.PeristalsisSynchronized or coordinated contraction of the muscles that propel food nội dung through the gastrointestinal (GI) tract to lớn facilitate normal digestion và the absorption of nutrients. Peristalsis is dependent upon the coordination between the muscles, nerves, and hormones in the digestive tract.PharmacogenomicsThe study of how genes affect a person’s response to drugs.PharmacokineticsHow the body handles a drug, including how it is absorbed, circulated, transformed, & eliminated.PhysiologyThe study of how the body toàn thân functions at the levels of organs, cells, and molecules.Pilot studyThe initial study examining a new method or treatment.PlaceboA placebo is an effect, not merely a thing.

A primary care doctor is able to give sầu a wide range of care, including prevention và treatment, và can refer a patient lớn a speciadanh mục.Primary lactase deficiencyWhen a person is born with the inability lớn digest lactose, a sugar found in milk and milk products. Lactose can’t be digested because there is not enough of an enzyme, called lactase, in the body toàn thân. Consuming milk & dairy products causes diarrhea, bloating, gas, và discomfort.

SatietyFeeling of fullness.Scientific knowledgeThe current mix of peer-evaluated consensus models about how natural phenomena work, which often differ between groups of researchers at the retìm kiếm frontier.Scientific progressThe cumulative sầu growth of a system of knowledge over time, in which useful features are retained and nonuseful features are abandoned, based on the rejection or confirmation of testable knowledge.ScintigraphyAn imaging method in which a mild dose of a radioactive sầu substance is swallowed to show how material moves through the GI tract.Sensitivity (diagnostic)The ability of a kiểm tra khổng lồ correctly identify a disease or condition (positive kiểm tra result) when it is present.SensitizationEnhancement of a response by an organism that is produced by delivering a strong, generally noxious, stimulus. A neuron becomes more excitable or responsive; it may respond more intensely lớn naturally occurring stimuli, either peripherally (in the viscera) or centrally (in the brain).Serotonin (5-hydroxytryptamine, or 5-HT)A chemical neurotransmitter (a chemical that acts on the nervous system khổng lồ help transmit messages along the nervous system). It is found in the intestinal wall và the central nervous system. More than 90% of the serotonin in the body resides in the gut.Short bowel syndrome (short gut)A condition in which nutrients are not properly absorbed because a large part of the small intestine is missing or not functioning properly.Sigmoid colonThe S-shaped section of the colon that connects khổng lồ the rectum.SigmoidoscopyExamination of the inside of the sigmoid colon và rectum using an endoscope — a thin, lighted tube (sigmoidoscope). Samples of tissue or cells may be collected for examination under a microscope. Also called proctosigmoidoscopy.Significant or statistically significantA statistical term indicating that the results of a study are stronger than would be expected from chance alone.Skin testA thử nghiệm for an immune response khổng lồ a compound by placing it on or under the skin.Small intestineThe part of the digestive tract that is located between the stomach và the large intestine.SoilingStaining or soiling undergarments with stool.SomaticPertaining to the physical body toàn thân.SomatizationThe body’s propensity lớn accentuate certain pain; physical symptoms & no recognizable physical abnormality.Specificity (diagnostic)The ability of a kiểm tra to lớn correctly classify an individual as not having a disease or condition (negative sầu thử nghiệm result) when it is absent.SphincterRing of muscle that opens và closes.Sphincter of OddiA muscle at that juncture of the bile và pancreatic ducts and the small intestine.

It most commonly occurs in middle-aged women who have had their gallbladder removed. Treatment may involve surgery or medicines aimed at decreasing resistance to lớn the flow of bile or pancreatic juice caused by the sphincter dysfunction.Spinal cordA column of nerve tissue that runs from the base of the skull down the baông chồng. It is surrounded by three protective membranes, & is enclosed within the vertebrae (bachồng bones). The spinal cord and the brain make up the central nervous system, & spinal cord nerves carry most messages between the brain và the rest of the body toàn thân.Squamous cellA flat cell that looks like a fish scale under a microscope. Squamous cells cover internal & external surfaces of the toàn thân.StressThe neurophysiological và subjective response to stimuli. In contrast khổng lồ the comtháng interpretation of the term “stress” as a psychological phenomenon, it should be understood as any real or perceived perturbation of an organism’s homeostasis, or state of harmony or balance. Stress may disrupt the function of nerve and even immune cells in the GI tract và in the brain. The central căng thẳng system involves the release of chemical căng thẳng mediators in the brain, which in turn orchestrate an integrated autonomic, behavioral, neuroendocrine, và pain modulatory response. This biological response in turn will alter the way the brain và the viscera (internal organs such as the gut/intestines) interact, and this altered brain-gut interaction can result in worsening of symptoms in functional GI disorders. For example, áp lực can increase GI symptoms by changing how the brain controls unwanted and painful sensation.StressorInternal or external factors or stimuli that produce bao tay. They can be physical, biological, environmental, or psychological; each can activate central căng thẳng circuits in an individual. For example, worry about the untimely & unpredictable onsets of uncontrollable abdominal pain or an uncontrollable bowel movement qualify as stressors sufficient khổng lồ activate the central bức xúc system.StrictureAbnormal narrowing of a body toàn thân opening.SynapseThe point between two nerve cells (neurons), across which chemical neurotransmitters carry messages.SyndromeA set of symptoms or conditions that occur together & suggest the presence of a certain disease or an increased chance of developing the disease.SystemicAffecting the entire toàn thân.Top of Page
