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.

Fluoride-induced rectal barrier damage and microflora disorder in mice.
Intestinal microflora plays a key role in maintaining the homeostasis between immune and host health. Here, we reported the fluoride-induced changes of rectal structure and microflora in mice. The morphology of rectal tissue was observed by hematoxylin and eosin staining. The rectal development parameters (the thickness of mucosa, intestinal gland

Probiotic alleviate fluoride-induced memory impairment by reconstructing gut microbiota in mice.
Highlights Memory function was reduced in the fluoride-exposed mice. Gut microbiota structure in fluoride-exposed mice was significantly altered. Lactobacillus was the mainly targeting bacteria in fluoride-treated mice. Inoculation with Lactobacillus johnsonii reconstructed gut microbiota in fluoride-exposed mice. Inoculation with Lactobacillus johnsonii rescued memory dysfunction in fluoride-expose mice. Fluoride which is

Effects of acute fluoride exposure on the jejunum and ileum of rats: Insights from proteomic and enteric innervation analysis.
Highlights Water containing 25 mgF/Kg bw F provokes morphological changes and alters in several proteins in the jejunum and ileum; Organism might not have had time to adapt to its toxic effect. Therefore, the loss of energy may have not been repaired. Morphological changes in the gut, can be explained

Allergy to fluoride
Six children and one adult exhibited various allergic reactions after the use of toothpaste and vitamin preparations containing fluoride. The following conditions were encountered: Urticaria, exfoliative dermatitis, atopic dermatitis, stomatitis, gastro-intestinal and respiratory allergy.

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),

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-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

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

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 & 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
