  • The dangers off fluoridation
    I live in an area where the water has been fluoridated for approximately 55 years and have been treated for an underactive thyroid since 1978. I have also suffered from urge incontinence since 1967 and for 4 years have also had the symptoms of skeletal fluorosis although I have not been able to get the tests to confirm this. About 2 years ago I read about the dangers of fluoride and stopped using the tap water for drinking and cooking but still had to use it for bathing and still swam in the local pool. Also I have always drunk about 3 pints of tea a day. Recently it was found that there might be a problem with my kidneys so I stopped drinking tea and swimming. I had been going to the toilet 16/17 times a day but after about 5 weeks this was down to 7/8 times and the urgency was gone. Also I was given a follow up kidney function test after 6 weeks and that was normal. A few weeks later I was shopping in an area where the water is not fluoridated and risked having tea in a cafe there and the irritable bladder symptoms came back almost immediately and lasted for several weeks.
  • Blood sugar level while taking veltrex
    I been taking Veltrex for a viral infection in my eye for 3 days and today my blood sugar was 448.My normal blood sugar runs around 146.
  • Syntroid and pruritus
    I have been on levothyroxine for more than ten years and have had two episodes, each lasting over several months of unbearable itching. Doctors seem to deny any connection but are also unable identify the cause of the itching. None of the tests pick anything. Antihistamines are not much of a help. I am still in the throes of the second episode and life is plain, simple miserable.
  • Thrush while on prograf
    I am a health provider at an emergency room and had a patient come in because of a food bolus and when i examined his oral/pharynx I noticed he had thrush. Patient stated it has been their for a while. Patient also stated he has been having progressive difficulty in swallowing. Pt is a kidney transplant patient and has been worked up for other causes of his thrush (including HIV, as per patient results neg) and everything came back negative. I can only conclude that maybe the prograf which is a immunosupressent can possible be the cause
  • Cardio version caused fingernail abnormalities
    Right hip fracture. When prepping for surgery AFIB was found. Surgery was cancelled and they attempted to get AFIB under control. Finally, cardioversion was performed. When my nails started to grow out they all had two horizontal lines that cause the nail to break when it grows out to that point.

  • From this study (1 month ago):

  • I have a history of pituitary brain tumors (one as an infant, surgically removed and treated with chemo, and one at the age of 7 treated through radiation). I had another brain tumor (miningeoma behind the eye nerves) that has led to these latest bouts of headaches and my rethinking of my health. I have always struggled with weight and am on every hormone replacement due to the effect on my pituitary. I am currently on a mostly vegan diet, which I have generally enjoyed but am starting to reevaluate.
