Abstract

BACKGROUND:
Fluorosis ranks high among the major environmental health problems in India. Non-ulcer dyspeptic complaints are common in humans and it is a known fact that fluoride in drinking water, food and other items can cause these symptoms.

METHODS:
Fifty adult outpatients (mean age: 35.2±12.7y) with chronic abdominal pain of unexplained origin were tested for their serum, urinary, and drinking water fluoride (F) concentrations. These concentrations were compared with those of 50 asymptomatic outpatients (mean age: 37.4±11.5y) and analysed statistically.

RESULTS:
Serum F concentrations were higher than normal in 62% of the study group I and in 42% of the control group II with a mean of 0.065±0.03ppm (range: 0.010-0.421) in the former and 0.023±0.028ppm in the latter. Statistical analysis of the data by Student’s t-test (unpaired) revealed a significant correlation (p<0.05) between chronic abdominal pain and elevated serum F. Urinary fluoride concentrations in group I were 0.87±1.67 (0.01-3.7)ppm. Seventy-three percent of the patients examined for urinary fluoride concentrations were having higher values than normal, whereas 27% patients had normal range urinary fluoride concentrations despite raised serum fluoride concentrations.

CONCLUSIONS:
In the cases of chronic pain abdomen, chronic fluoride ingestion from drinking water and other sources can be the cause and should be evaluated in patients in which other parameters are normal.

  • Toxic effects of chronic fluoride ingestion on the upper gastrointestinal tract

    In a prospective case controlled study, we evaluated the adverse effects of long-term fluoride ingestion on the gastrointestinal tract. Ten patients with otosclerosis who were receiving sodium fluoride 30 mg/day for a period of 3-12 months, and 10 age- and sex-matched healthy volunteers were included. They were all evaluated clinically

  • Fluorosis by the Ministry of Health & Family Welfare, National Health, India.

    Introduction Fluorosis is a crippling disease resulted from deposition of fluorides in the hard and soft tissues of body. It is a public health problem caused by excess intake of fluoride through drinking water/food products/industrial pollutants over a long period. Ingestion of excess fluoride, most commonly in drinking-water affects the teeth

  • Gastroduodenal manifestations in patients with skeletal fluorosis

    A prospective case-controlled study was performed to evaluate the gastrointestinal symptoms and mucosal abnormalities occurring in patients with osteofluorosis. Ten patients with documented osteofluorosis and ten age- and sex-matched healthy volunteers were included in the study. Clinical evaluation, real-time ultrasound, and upper gastrointestinal endoscopy and biopsy from the gastric antrum

  • Chronic fluoride exposure alters antioxidant enzymes in rat brain and intestine

    Background: Low Fluoride use has been advocated as a therapeutic agent for delaying tooth decay however, high fluoride exposure has been associated with behavioral changes, low IQ, and altered brain functions and development. Although Fluoride generally does not generate free radicals but is still implicated in free radical associated damage

  • Effects of fluoride on structure and function of canine gastric mucosa

    These studies were done to determine the effects of fluoride (F) on the structure and function of the canine gastric mucosa and the possible protective effects of 16,16-dimethyl-prostaglandin E2 (dmPGE2). A portion of the stomach with its vascular supply intact was mounted in a two-compartment chamber, one side of which

    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

    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.

    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
