Abstract
The effects of sodium-fluoride (7681494) on gastric secretion were studied in rats. Male albino-rats were administered 25 milligrams per kilogram sodium-fluoride in their drinking water for 60 days. Selected rats were killed after 7, 15, 30, and 60 days, and stomachs were dissected out, the gastric juice collected, and the volume recorded. After centrifugation to remove suspended food particles, the gastric juice was analyzed for free and total acidity. Peptic activity was determined. Gastric volume was significantly increased after 30 and 69 days of sodium-fluoride treatment. Total acidity increased progressively with duration of treatment. Free acidity was significantly increased after 30 and 60 days. The increase in total acidity at 30 and 60 days was mainly due to the increase in free acidity. Peptic acidity was increased at all time points in treated animals, with the greatest increases occurring after 30 and 60 days. The authors suggest that elevation of cyclic-adenosine-monophosphate concentrations in the stomach by sodium-fluoride can stimulate hydrogen ion output. This could explain the gastric symptoms of individuals in endemic fluorosis areas and workers exposed to air contaminants containing fluoride.

Sodium fluoride-induced gastric mucosal lesions: comparison with sodium monofluorophosphate
In a randomized double-blind study with two parallel groups of 10 male healthy volunteers each the response of gastric mucosa after a 7 days ingestion of sodium fluoride tablets (NaF) or sodium monofluorophosphate tablets (MFP) was compared. Gastroscopic evaluations were performed before treatment, day 1 and day 7. Simultaneously blood

Fluoride-related bone disease associated with habitual tea consumption
Acquired osteosclerosis is a rare disorder of bone formation but an important consideration in adults with sclerotic bones or elevated bone density results. In such patients, malignancy, hepatitis C, and fluorosis should all be considered when making a diagnosis. We describe 4 patients evaluated at our Metabolic Bone Disease Clinic

Allergic reactions from fluorides
In a discussion of drug allergy it is necessary to distinguish between intolerance and allergy to drugs. One represents intoxication, the other is characterized by wheal formation, eosinophilia and other features of an allergic reaction. Gastric irritation, for instance, or acne from iodides or bromides represent intolerance to these drugs

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-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

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
