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.

Intestinal changes associated with fluoride exposure in rats: Integrative morphological, proteomic and microbiome analyses.
Highlights Fluoridated water increases the thickness of the ileum wall. Fluoridated water increases CGRP-IR and SP-IR varicosities in the ileum. Proteomic changes induced by fluoride have similarity with Crohn’s disease. Microbiomic changes induced by fluoride are associated with inflammation. Abstract Gastrointestinal signs and symptoms are the first signs of toxicity due

Intestinal fungal dysbiosis in mice induced by fluoride
Highlights The relative species abundance of intestinal fungi in mice was affected by fluoride. Fluoride mainly affected intestinal fungi in mice at the genus level. There was a strong positive correlation between Penicillium and Pluteus. To explore the effects of fluoride on intestinal fungi in mice, the internal transcriptional spacer (ITS)

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

Effect of Fluoride in Drinking Water on Fecal Microbial Community in Rats.
Intestinal nutrition has a close association with the onset and development of fluorosis. Intestinal microbes play a major role in intestinal nutrition. However, the effect of fluoride on intestinal microbes is still not fully understood. This study aimed to evaluate the dose-response of fluoride on fecal microbes as well as

Fluoride toxicosis in immature herbivorous domestic animals living in low fluoride water endemic areas of Rajasthan, India: An observational survey
Susceptibility to fluoride toxicosis in the form of osteo-dental fluorosis was observed among 435 immature herbivorous domestic animals living in areas with less than 1.5 ppm fluoride in the drinking water. These animals included 78 buffaloes (Bubalus bubalis), 89 cattle (Bos taurus), 30 donkeys (Equus asinus), 21 horses (Equus caballus),

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

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

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

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
