Abstract
Czerwinski and Lankosz reported that 7 out of 60 retired workers (12%) in a Polish aluminum plant, who showed evidence of low-grade skeletal fluorosis, were afflicted with gastric ulcer. Such a high incidence raises the question whether or not certain kinds of ulcers in the stomach and upper intestinal tract might be related to F-. The daily diet contains F-. A cardinal feature of acute poisoning from inorganic fluoride compounds is severe vomiting, extreme pain in the epigastrium and gastric hemorrhages. At autopsy, ulcerations of the stomach and the upper intestinal tract are almost always present. The degree of damage to the gastric mucosa, i.e., the severity of the ulceration, is dependent on the amount of the fluoride compound ingested, the tightness of the bond of the F- in the molecule of the compound and the acidity of the stomach of the individual patient.

Topical fluorides: effects on physiologic and biochemical processes
The ingestion of fluoride from dentifrices or mouthrinses can contribute substantially to the total daily intake of the ion, even in communities that provide optimally fluoridated drinking water. It is concluded that the frequent and unsupervised use of these products by children six years of age or younger, especially those living in

Gastric discomforts from fluoride in drinking water in Sanganer Tehsil, Rajasthan, India
A health survey of 1135 children and 1475 adults living in Sanganer Tehsil, Rajasthan, India, revealed a wide range of gastrointestinal (GI) discomforts associated with fluoride (F) in the groundwater in over 30 village areas. Complaints of abdominal pain including stomach ache, a bloated feeling, nausea, diarrhea, and constipation were

Effect of Fluoride on Small Intestine Morphology and Serum Cytokine Contents in Rats.
This study aimed to determine the effect of excessive fluoride (F) on the morphological characteristics of the small intestine and the contents of serum cytokines in rats. A total of 48 3-week-old healthy female Sprague-Dawley rats were randomly divided into four groups (n?=?12). The control group was given deionized distilled

Suppressive effects of dietary high fluorine on the intestinal development in broilers
Fluoride (F) is a well-recognized hazardous substance. Ingested F initially acts locally on the intestines. The small intestine plays a critical role in the digestion, absorption, and defense. In this study, therefore, we investigated the effects of fluorine on the intestinal development by light microscopy, transmission electron microscopy, and histochemistry.

Fluoride-Induced Damage to Gastric Mucosa in Human Clinical Trials
When fluoride has been used (at doses of 18-34 mg/day) as an experimental treatment for osteoporosis, gastric pain is one of the two main side effects consistently encountered. To better understand how fluoride causes this effect, researchers have sought to determine how fluoride affects the tissue that lines the gastrointestinal tract. In a

Side Effects from Fluoride Gels: Gastric Distress
Gastric distress -- including nausea, pain, and vomiting -- is one the most common side effects from professional application of "fluoride gels" at the dentist. Patients receiving fluoride gels can swallow more than 20 mg of fluoride from a single treatment -- doses that far exceed the doses that can

Fluoride-Induced Gastric Symptoms in Human Clinical Trials
In studies where fluoride has been used (at doses of 18-34 mg/day) as an experimental drug for the treatment of osteoporosis, gastrointestinal disturbances are one of the two main side effects consistently encountered. The following are some of the accounts from the published literature: "The use of fluoride in the prophylaxis or

Fluoride & Gastrointestinal System: The Importance of Fluoride Concentration in Stomach
The following is an excerpt from the National Research Council's (2006) review of fluoride toxicity: "It is important to realize that GI effects depend more on the net concentration of the aqueous solution of fluoride in the stomach than on the total fluoride dose in the fluid or solid ingested. The

Gastrointestinal Problems Among Individuals with Skeletal Fluorosis
Humans suffering from skeletal fluorosis are known to suffer from an increased occurrence of gastrointestinal disorders. When fluoride intake is reduced, these gastrointestinal problems are among the first symptoms to disappear. The following are some of the studies that have examined this issue: "It is clear from the observations presented in this article
