Sufferer's website of body odor theories : Bodyodor777.com

Everybody has body odor, some more than others. This website is for those who have strong, chronic body odor and are trying to find an end to this torture. I have compiled my research in this web to help as much as possible. There is no definite remedy for everybody, but the concrete information in this web will facilitate your search to find a cure.This website, bodyodor777.com seems to be run by a sufferer trying to make sense of the maze of body odor (which as anyone with the problem knows, for the vast majority of sufferers is far more complex than society thinks). They have gathered their own ideas as to possible theories. It presents an interesting general overview of internal and external causes of strong, chronic body odor. Of particular interest is the Internal Causes section that in addition to the ones normally come to mind related to metabolic disorders, hormones, mouth, nose, throat, and intestines, it also discusses sources such as the gallbladder, kidneys, allergies, liver, food intolerance, acidic body, anorexia nervosa, and more.

Your gut : a bag and 2 pipes

your gut : a bag and 2 pipes

stomach : small bag on the upper left abdomen. preparation bag. 

small intestine : long thin coiled pipe designed for maximum absorption
colon : wide shorter looping (one loop) pipe. recycling plant. loads of bacteria

The digestion system seems likely to play a part in fecal body odor and other metabolic body odors (e.g. secondary trimethylaminuria), so it's probably important we understand it best as possible. This post is about the basic visual and mechanical structure and main purposes. What does the gut look like and do ?

Stomach : a small bag on the upper left hand abdomen. This is where food first ends up. Generally it is held here and turned to mush and then released into the small intestine through the pyloric valve in small controlled amounts. Simple carbs won't stay long, whereas a meal will take a while. Hydrochloric acid is added to it, and some other things to make it easier to digest. The mush is called 'chyme'. Each part of the intestine is separated by valves.

Small intestine : A long thin pipe that coils in an overlapping way. This is the main absorption point. It is designed for maximum absorption of molecules of a certain small size. There are millions of finger-like microvilli on the lining (like a carpet) to make 'catching' the molecules easier. It's this microvilli that is wiped out in full-blown celiac. The pancreas puts digestive enzymes into the pipe early on to break down the food, and bile is also squirted in by the gallbladder to digest fats. The absorbed molecules go into the portal vein and then are taken to the liver for filtering before entering the main circulation. The intestine acts as a barrier so that large molecules cannot get into the portal vein unless broken down. With leaky gut (which is really leaky small intestine), large molecules can get through junctions in the barrier and so are absorbed when they shouldn't be. Because you want maximum absorption here, there is usually very few gut microbes here, especially at the top end, largely because they would compete with you for the food. The small intestine is known as 3 parts ; duodenum, jejunum, ileum. Many feel that when someone has gut candidiasis overgrowth, it's growing at the ileum (for example). However, it's likely that overgrowth of anything in the colon will cause problems too. The small intestine and colon are separated by the ileocecal valve.

Large Intestine/colon : A short, wide pipe that ascends from your appendix area, goes up to your ribcage and across, and down the other side and then loops to the anus. the colon is where most bacteria is, even in a healthy gut. Good flora scavenges from any leftover food/chyme and many produce helpful fatty acids. The protein/sulfur eating bacteria tend to be at the lower left side of the colon (near the end). The chyme becomes feces as water is absorbed and the 'rubbish' is then exited.

It's probably more complicated than that but hopefully this gives you an image in your mind of what the gut mechanically looks like.

What goes wrong ?

Some examples. If anything is wrong with the digestion enzymes such as HCL, pancreatic enzymes, bile etc, you can end up with too much undigested food entering the colon which will likely alter the flora ecology detrimentally. for instance too much protein getting into the colon.

If the tight junctions in your small intestine barrier cells are weakened you can absorb molecules too big that are not intended to be absorbed. These enter the portal vein and are sent to the liver which likely regards these as unexpected molecules.

If conditions aren't right, perhaps microbes can colonize the lower small intestine or further up.

Perhaps the colon microbes can be unnaturally altered and produce toxins. In Secondary TMAU, the diagnosis means there is too much trimethylamine produced. It's currently thought the bacteria that produce this are in the colon, so it means overgrowth of this bacteria. Who knows if this bacteria can grow in the small intestine as well. Presumably no-one is currently looking whereas a Body Odor & Research center likely would be.

Intro letter

MEBO RESEARCH FOUNDER
AND EXECUTIVE DIRECTOR

As a 54 year-old married mom with two sons living in Miami, Florida, I have personally struggled with severe body odor in my family throughout my life, and especially these past eight years, the odor has been impossible to control. The most exasperating aspect of the struggle to control and cure this condition was not finding answers from numerous well-intentioned medical doctors, including gastroenterologist, dermatologist, allergy and asthma specialist, and othorhinolaryngologist. As a result, I had no other recourse but to turn to the web to find guidance and answers.

After having read numerous research articles online from around the world, heart-wrenching posts by body odor sufferers in many Body Odor/TMAU forums, and after watching various news and talk shows regarding this matter, it seems to me that most cases don’t fit the traditional idea of body odor as being an external skin problem. By that I mean that it is bloodborne and systemic, to be released through the pores and any way it can through all the body cleansing organs - lungs, kidneys, skin, and glands. I am also amazed at the number of sufferers posting on the online boards. It seems as if it is far from a rare problem, although it seems to vary in degree of intensity.

I began to see a pattern emerging in numerous parts of the world suggesting that body odor is a medical condition that usually arises from more than one cause in each individual sufferer, such as metabolic and/or gut bacterial imbalance, triggered by physical and emotional stress and hormonal changes, and possibly other causes yet to be discovered, many of which are genetic in nature. These multiple causes in one individual sufferer may vary from another sufferer, thus making it extremely difficult if not impossible for sufferers to find a lasting solution to their respective body odor condition without additional research and professional guidance.

The function of this blog is multifaceted as it serves as a channel between experts and sufferers to promote awareness and funding for research, and to achieve a good solution to enable sufferers to help themselves. First and foremost, I would like all sufferers who visit and participate in this blog to be assured that I commit to doing everything in my power to protect your privacy and confidentiality throughout this process. And experts, this blog will serve as a tool for you to tap into an international pool of sufferers who are very eager to assist you in finding a good understanding of the various causes of body odor and a solution to our problem; so please feel free to get in touch with me at any time, maria.delatorre@meboresearch.org, and I will do everything possible to assist you regarding this matter.

SUFFERERS UNITED

Through this blog sufferers of various body odor forums, as well as other sufferers, can come together in larger numbers to provide the scientific community with data for research, surveys and questionnaires. In turn, sufferers can find in this blog, online articles of scientific and medical information related to body odor and its management. In this manner, I hope that sufferers and experts unite and arrive at a better understanding of the various causes of body odor, develop an effective course of treatment for each condition, and most importantly, find a cure.

It is my sincere wish that the outcome of this effort will result in a future commonplace practice of a sufferer going to his or her family doctor anywhere in the world presenting with body odor as his or her primary complaint, that the physician would immediately know what metabolic and/or microbial diagnostic exams are indicated in order to arrive at a speedy diagnosis and treatment plan to control and eliminate body odor. It saddens me that people can be suffering so much misery, with the medical world seemingly unaware except for perhaps a handful of experts who know about trimethylaminuria. It is also my aim that all private and group health insurance plans as well as national medical plans routinely cover the diagnosis and treatment expense of these conditions as it would any other medical condition so that bloodborne body odor sufferers can afford to seek proper medical treatment.

I therefore invite all members of all body odor forums and websites, and all who suffer from body odor, family and friends, and the scientific, medical, and healthcare community throughout the world to unite and to participate in this endeavor to find real answers. Sufferers may do so by providing as much accurate data as possible to whatever questionnaire or survey researchers post in this blog to assist with their research, while feeling confident that their privacy will be protected. Researcher should feel welcomed with open arms to carry out their research projects in this endeavor tapping into a strong pool of available subjects in a joint effort to find a cure for body odor. In this data and information exchange effort, we can unite at an international level to achieve all these goals so that we can provide a happy and productive life for ourselves, our children, and future generations.
