Abstract
A prospective case controlled study was conducted to evaluate the role of fluoride as a possible aetiological factor for non-ulcer dyspepsia (NUD). Twenty patients with NUD and 10 age and sex matched healthy controls were subjected to clinical evaluation, upper gastrointestinal endoscopy and biopsies from the gastric antrum and duodenum. The antral and duodenal mucosa was subjected to a rapid urease test for Helicobacter pylori and histological and electron microscopic examinations. Fluoride levels in the drinking water, serum and urine were estimated using a ION 85 ion-analyser. These levels were significantly higher in patients with NUD than in controls (P less than 0.05). Histological abnormalities in the antral and duodenal mucosa were seen in 14 patients (70%) with NUD and 1 control subject (10%) (P less than 0.05). Electron microscopic abnormalities in the mucosal cells were seen in all patients with NUD but in none of the controls (P less than 0.01). The fluoride levels in serum and urine correlated with the symptoms, histological and electron microscopic abnormalities (P less than 0.05). It was concluded that chronic exposure to fluoride may result in NUD and should be considered in patients where other known cause of dyspepsia have been excluded.

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

Fluoride: a risk factor for inflammatory bowel disease?
Although the association between inflammatory bowel disease (IBD) and oral hygiene has been noticed before, there has been little research on prolonged fluoride exposure as a possible risk factor. In the presented cases, exposure to fluoride seems indirectly associated with higher incidence of IBD. Fluoride toxicology and epidemiology documents frequent unspecific chronic gastrointestinal symptoms and intestinal

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

Treatment of primary osteoporosis with fluoride and calcium: clinical tolerance and fracture occurrence
Thirty-six patients with primary osteoporosis were treated for up to six years with sodium fluoride, calcium supplements, and, in 24 patients, vitamin D. Major adverse reactions (synovitis, painful plantar fascial syndrome, recurrent vomiting, or anemia) occurred in 15 patients (42%). New vertebral fractures occurred at a rate of 329 fractures

Skeletal fluorosis: an unusual metabolic bone complication for HPN patients
Rationale: Prevalence and pathophysiology of HPN-associated metabolic bone disease (MBD) xe patially unknown. Therefore, we began a systematic review of 0ur patients in order to increase our knowledge in this paticular field. Here, we report two cases of skeletal fluorosis, an unusual HPN-related bone abnormality. Method: Until now, 12 patients (6

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
