How can I effectively treat bad breath and body odor?

The thyroid gland is an organ in the human body that secretes a hormone called thyroxine that helps maintain the metabolism of the body. I classify thyroid issues broadly into a hormone issue vs an anatomical issue. For hormone issue, if the problem is that of “high levels” or Hyperthyroidism, patients present with symptoms of a “high metabolic state”, for example, unintentional weight loss, palpitations or sense of heart beating very fast, feels hot and perspires more than usual, anxiety or nervousness, tremors of their hands.

I'm so sorry to hear about your frustrations with bad breath. I've had many patients seek treatment for bad breath at my practice and I know how distressing it can be, especially when you have tried "everything". From my experience, for someone who has been cleared from any form of dental disease, the cause of the bad breath can be ENT-related. I would advise you to seek an opinion from an ENT surgeon, and possibly a second opinion from another dentist just to be sure that your first dentist didn't miss anything. Dr Marlene's article is very useful, and I also agree with Dr Jaclyn's pointers.
