  Fluoride & the Gastrointestinal Tract
Fluoride ingestion and its correlation with gastrointestinal discomfort.
Gastrointestinal symptoms consist of epigastric pain, nausea, vomiting, and occasionally, blood-loss anemia; these presumably result from the irritant effect of fluoride ion on gastric mucosa.
It is concluded that in an endemic (fluorosis) zone, where the inhabitants are consuming water of high fluoride content, the occurrence of gastrointestinal complaints - viz., loss of appetite, nausea, abdominal pain, flatulence, constipation and intermittent diarrhoea - is one of the early warning signs of fluoride toxicity and fluorosis.

reported a 69% prevalence of histological esophagitis and a 58% prevalence of intestinal disaccheridase deficiency in a group of 36 autistic children studied by upper gastrointestinal endoscopy and biopsy (9).
The pathophysiology of these gastrointestinal expressions of a central nervous system is often unclear, but may variably reflect the parallel involvement of the gut and brain by the same disease process or the consequences of a primary disease of the brain or gut on the gut or brain, respectively.
Pending the performance of appropriate studies, which should include both asymptomatic autistic children as well as children with other developmental disorders, these findings cannot and should not be extrapolated to children with autism in general.

 Gastrointestinal Tract
The gastrointestinal tract begins with the mouth, leads to the esophagus and extends through the stomach, small and large intestine, to end at the anus.
Although the overall sensitivity of symptoms for the detection of gastrointestinal lesions was low, logistic-regression analysis demonstrated that the presence of symptoms in the upper gastrointestinal tract was associated with the detection of lesions in the upper gastrointestinal tract (odds ratio, 2.6; 95 percent confidence interval, 1.4 to 4.7).
Recognition of the rhabdoid phenotype in gastrointestinal tract neoplasms is important because this feature is associated with poor prognosis and unresponsiveness to conventional therapy.

"The Gastrointestinal Tract in Scleroderma," by Sidney Cohen, M.D. Coping with Scleroderma
The gut or the intestinal tract is involved in, perhaps, 80% to 100% of patients with the systemic form of scleroderma, as we will describe it.
In the GI tract this is the most important symptom to prevent and is one that can be prevented.

 Bleeding in the Gastrointestinal Tract
Bleeding in the digestive tract is a symptom of digestive problems rather than a disease itself.
The most common source of bleeding from the upper digestive tract is ulcers in the duodenum (the upper small intestine).
This technique involves injection of small amounts of radioactive material that are either attached to the patient’s red blood cells or are in a suspension in the blood.

 Gastrointestinal Disorders   (Site not responding. Last check: )
Gastrointestinal motility is defined by the movements of the digestive system, and the transit of the contents within it.
When nerves or muscles in any portion of the digestive tract do not function in a strong coordinated fashion, a person develops symptoms related to motility problems.
They are the most commonly presented gastrointestinal illnesses seen by physicians in primary care or gastroenterology.

 CDC - Anthrax of the Gastrointestinal Tract
Gastrointestinal anthrax is greatly underreported in rural disease-endemic areas of the world.
The pathologic examination of anthrax lesions with entry via the GI tract shows that the mucosa is always involved, as are regional lymph nodes, which are enlarged and hemorrhagic (15).
The GI tract may also be involved after disseminated infection in pulmonary and sometimes cutaneous cases (20–22).

 Gastrointestinal Bariatric Surgery
Gastrointestinal surgery promotes weight loss by closing off parts of the stomach to make it smaller, thus restricting food intake.
These procedures create a direct connection from the stomach to the lower segment of the small intestine, bypassing portions of the digestive tract that absorb calories and nutrients.
Weight loss surgery has a direct impact on obesity, although obese patients are advised that any bariatric or gastrointestinal surgery must be accompanied by weight-related lifestyle changes in the form of diet modification and increased physical exercise.

 Lower GI Tract X-ray
Lower gastrointestinal (GI) tract radiography, also called a lower GI, is an x-ray examination of the large intestine, also known as the colon.
When the lower gastrointestinal tract is filled with barium, the radiologist is able to view and assess the anatomy and function of the rectum, colon and part of the lower small intestine.
X-ray imaging of the lower GI tract is a minimally invasive procedure with rare complications.

 ACS :: What Is Colorectal Cancer?
gastrointestinal stromal tumors – these tumors develop from specialized cells in the wall of the colon called the "interstitial cells of Cajal." Some are benign (non-cancerous); others are malignant (cancerous).
Although these cancers can be found anywhere in the gastrointestinal tract, they are unusual in the colon.
Separate documents about gastrointestinal (digestive system) carcinoid and stromal tumors are available from the American Cancer Society.

 Alcohol and GI Tract
The GI tract, generally considered a continuous tube extending from the mouth to the anus, is subdivided into different segments: oral cavity, pharynx, esophagus, stomach, small intestine, large intestine, rectum, and anal canal.
The GI tract’s job is to physically and chemically break down the food that you eat.
In healthy humans, alcohol consumption significantly reduces the frequency and strength of the muscle contractions in the segment of the rectum, which could reduce transit time of intestinal contents and contribute to diarrhea frequently observed in alcoholics.

 Gastrointestinal Tract
To better understand how weight loss surgery works, it is important to understand how your gastrointestinal tract functions.

Activity in the gastrointestinal tract after administration of bone-seeking radiopharmaceuticals.
PURPOSE: To test the possibility that (radio)activity of non-pertechnetate nature is excreted into the gastrointestinal tract at bone scintigraphy.
RESULTS: A comparison of the activity of the submandibular glands, which are assumed to accumulate only pertechnetate, and the gastrointestinal tract showed that a significant fraction of the activity excreted into the gastrointestinal tract did not consist of pertechnetate.

 Cancer Institute - Surgical Oncology - Tumors of the Gastrointestinal Tract - Mercy
Tumors of the gastrointestinal tract include several types of cancers including esophageal, gastric (stomach), small bowel, colon and rectal.
Small bowel tumors are rare and difficult to diagnose because the middle portion of the gastrointestinal tract is not easily accessible to conventional tests.
Palliative surgery is performed to relieve symptoms and reduce pain in cases where the tumor has already spread extensively and is difficult to remove or if the patient is too ill to tolerate more aggressive surgery.

 Sluggish Motility in the Gastrointestinal Tract
This is a condition that doesn't really exist in the opinion of a growing number of veterinarians who care for rabbits.
By that I mean that the primary problem is not a hairball, but rather a problem with sluggish motility of the gastrointestinal tract (GIT) leading to dehydration and impaction of material in the stomach and cecum.

Infection of seronegative calves and non-pregnant cattle by either strain of virus results in an outbreak of BVD or is followed by subclinical infection, depending on individual immune capacity.
BVDV is replicated in the cells of the alimentary tract, but also in leukocytes, reducing their number drastically for a period of one to two weeks.
It is of enormous importance to survey the livestock for virus carriers whenever you suspect BVDV infection in a single animal.

Gastrointestinal tract: The tube that extends from the mouth to the anus in which the movement of muscles and release of hormones and enzymes digest food.
The gastrointestinal tract starts with the mouth and proceeds to the esophagus, stomach, duodenum, small intestine, large intestine (colon), rectum and, finally, the anus.
Also called the alimentary canal, digestive tract and, perhaps most often in conversation, the GI tract.
