Dear friends
My daughter is 38 years old, does not smoke  and we live in Brazil. She suffers from halitosis but the smell is not a very bad smell of the breath. The smell of her breath is a different one, in a certain way with the negative impression similar to the breath of a smoker but, in her case, with totally different characteristics and one particular odor. The smell increases strongly when she is in a situation of tension and /or stress. It is difficult to define the odor/smell of her breath but, even at the distance of 1,5 meters we can feel it. The odor seems a odor of ashes, of something burnt, seems to be acid, etc…
Thank you very much for your comments and suggestions.

Sounds to me like she needs to look into naturopathic medicine and start doing liver flushes and colon cleansing.  Infrared saunas would help also if you can find any locally.

Perhaps the diagnosis is "trimethylaminuria", also known as "Fish-Odour Syndrome", of which there are at least 200 cases on record, the first of which was recorded in 1970.

Probably the first mention of it is in the Indian Mahabharata, which is one of the two major Sanskrit epics. In it the story tells of a young woman, Satyavata, who gave off a smell like rotting fish. Society rejected her because of the smell, but luckily a sympathetic god took pity on her and cured her.

Other animals can be affected too - Certain Rhode Island Red chickens lay fishy smelling eggs, particularly if the diet is rich in chemicals which can turn into trimethylamines (N(CH3)3).

Most humans produce trimethylamine (which smells like bad fish) from the food that we eat. It is not a problem for most of us because we make an enzyme that breaks down trimethylamine. But in some individuals this enzyme is absent, or present only at very low levels, meaning that they accumulate high levels of trimethylamine in the bloodstream. When the blood goes through the lungs, some of the trimethylamine is breathed out - giving these poor unfortunates the persistent odour of rotting fish. Trimethylamine also leaches out of the body in sweat, and gets into urine, although you probably don't often have to smell people's wee so much as their breath !

In relation to recent Atkins 'fad' diet, the induction of ketosis, a metabolic process, ledas to production of chemicals called ketones which are excreted in the urine and can also affect breath. It is possible that one of a number of metabolic defects may be responsible for generating odouriferous chemicals in the breath.
