Bad Breath Starts in Your Gut (& How to Fix It)

A fascinating new study has found that bad breath, or “halitosis” may be correlated with gut issues. In the study, 99% of those who were given treatment for their gut health actually fixed their bad breath! In this episode, I’ll break down the connection between conditions like SIBO and bad breath, and I’ll recommend an effective probiotic protocol to treat bad breath.

Thank you for this video Dr.

I have been battling bad breath since12 Years old. I left a job last August 2024.
I had chronic bad breath, fecal body odor. I am now trying to fix this alone because the doctors here were saying that I am fine. It is all psychological.

I suffered a lot. I don’t like to engage with people. I have low self esteem now.

I am taking liquid chlorophyll everyday;
2 - Taking fermented probiotics oats made at home by myself;
3 - supplementing With morninga everyday ;
4 - taking vitamin D3 everyday.

I will come after 6 months to tell how I am feeling.

[SimretKebede]

Finally you speak Exactly what I'm going through and the one and only solution for this, thank you Dr, you'r wonderful and brave man 💪💪💪

I’ve been on Dr. William Davis’s Sibo yogurt for 29 days so far and I can attest that before I started resolving the Sibo problem, I definitely constantly had a bad taste in my mouth.

[FlowerlyF.]

Finally! Thank you for educating on this „shameful“ and unfortunatley taboo topic ❤ what kind of sibo did they have?

[marga]

I heard that bad breath can be caused by parasites so my next steps will be to get a stool test. I feel very bad and shy away from people because it really bad!

Great information. Factual, actual, informed. Personal case that validates most information on your channel. For years i suffered with gut issues caused by antybiotics. Doctors always told me my skin issues had nothing to do with food. It did. I also had bad breath, irregular bowel movements, etc.
Once i regulated food, by removing processed foods, my skin improoved, that led me in a search for cause, and i found that skin wasnt the issue, it was the result of gut problems. Sibo, candida, leaky gut, caused mast cell, histamine, and other intolerances that then let to skin issues. Not yet solved, but proper food, plus probiotics, plus supplements to balance the foods that went out, are helping me return to normal. Small things. Like, much better skin, no longer having bad breath, being able to eat a fucking croissant without issues. But this will take a while. Healing the gut doesnt take weeks, it takes years. I dont mind. I had issues for 30 years and it only started to get better when i stopped listening to doctors!

I eat Dr Davis‘s probiotic yogurts for min. 6 months now, my bad breath is gone, in fact if I consume those yogurt before bed and not brushing my teeth, i wake up without any mouth odor at all. Also toothache is gone, which caused me some caries before.

Should you avoid boulardii if you're allergic to yeast?

[samantha]

I attest that SIBO plays a major role in bad breath/doughy sensation/white coating on the tongue. I've noticed it depending on what I eat. In my case I don't break down any food, my body doesn't produce enzymes, and I need supplement when I eat otherwise I get bloated as if I was pregnant. It took me years of research and medical testings ( belgians doctors : "everything's fine") to finally - by myself - come to the conclusion that I had SIBO and GERD (the worst of this is the cascade of ailments it causes) . Hopefully I'll figure why and what caused the enzymes deficiency and how I could possibly reset my body (1 or 2 week fast ?). I've never tried probiotic, I definitely will.

In the meantime, intermittent fasting is helping me a lot along with digestive enzymes.

[marga]

I have bad breath, tonsils stones as well ! I do get dental cleaning Q6 months, and floss everyday. My diet is pretty good focus on meats, seafood and poultry. I do get good quality carbs like sweet potatoes, pumpkin and cruciferous vegetables .

[jamiedorn]

Do the triple probiotics you recommend typically sit well for those with histamine issues ?
Ive been trying one strain at a time and still get dizzy, wondering if I should just go for the triple and see...

[merrytunes]

I was diagnosed with SIBO 6 years ago, and HPV 4 years ago. What supplements can I take to help eliminate them both?

[SimhlelelweNkambule]

Thank you so much Dr Emovon on YouTube for your treatment and your consultations. I'm forever grateful to you. You've been such a kind and caring doctor for me during my hard time of bad breath. Thank you for doing everything that you do and helping me during a hard time. I'll definitely spread this to the whole world, I'm totally free from bad breath..❤❤

[Sourpusscandy]

There’s no way I could eat a cup of sour kraut or kimchee. Maybe 1/4 c on the side. I appreciate your reporting on the studies.

[sarahsmith-nvez]

Wonderdul!! Thanks for the material. I'm on pro biotics. Also beleive I don't get enough prebiotic. But the halitosis can be frustrating due to myself not noticing so I dont know if and when it's improving. Your information is appreciated!!

Is there a reason to start with a lower number of billions of CFU or not really? Can I do for example 25 billion CFU and after a few months do a 5 billion CFU probiotic without jeopardizing efficacy?

[UKFISGODLIKE]

Why I always heard probiotics are awful when having sibo ?

[SamiMusicyou]

I have sibo and it was developed front taking probiotics

[KetobyDanielDumitriu]
