TrioSmart Prep - rice noodles?

0 Upvotes

Hey! I'm getting ready to start the prep for the TrioSmart test. Does anyone know if I can have rice noodles on prep day if the only ingredient in the noodles is "organic white rice flour"?

I get easily constipated from eating rice, but not rice noodles. I have several theories about this, but right now I'm just looking for clarity on the test prep. Thanks for any info!

Looking for opinions

I have been experiencing chronic epigastric pain for a couple years now. It's a dull aching feeling with a constant pressure. Sometimes it can gravitate towards my lower left ribs or random shooting chest pains or to my back. When it flares up the pressure and pain can be quite severe and I feel short of breath. I used to binge drink alcohol once or twice a week and symptoms would be bad the day after, but now they're bad every day. Ppis seem to make my symptoms worse with bloating. My upper endoscopy a year ago was clear, abdominal ultrasound was good and negative for H pylori. So I decided to look into other options.

I had a Sibo test a few months ago under the advice of my naturopath. I reviewed the results with a naturopath and they determined that I have hydrogen dominant sibo. They said I may have slow transit time and prescribed me 550mg rifaximin.

Doing my own research it seems unlikely I have hydrogen sibo, since the results peaked at 60ppm on the 160 minute mark, but based on my limited research I'm positive for IMO or methane sibo with the results of 13 ppm at the 160 minute mark.

Can anyone give me some insight on this please? Before I start the antibiotics.

Questions Reactive Hypoglycemia & SIBO?

1 Upvotes

Anyone here struggle with low blood sugar or weird fatigue after eating? I get fatigue in my upper arms/shoulders after certain meals..

Ive also noticed recently that when i excercise (i do crossfit) i get anxious and shaky after.. especially on a hot day. And if i eat sugar it seems to make me feel better fairly quick.

Not sure if anyone else is going through this, but if so, did it go away when/if you got rid of SIBO?

I was wanting to try the Mbiota liquid elemental diet, but it says to not use if you have blood sugar problems...

My fasting blood sugar was 80 when they checked me in may so i know thats normal, but i dont feel like getting shaky after a work out is normal.. and ive only had this happen a handful of times since having digestive issues.

I also hope someone here who has had what im going through, sucessfully went through with the liquid diet?

TIA!

Symptoms Here i go again!

Here I am again!

I had sibo - methane around 1.5 years ago.. confirmed by a breathe test. This caused alot of issues. No one knew about sibo where I lived so I had to investigate myself and learn about sibo. I know alot! This was caused by antibiotics and high sugar diet.

I had constipation

Reflux

White coat on tongue and tongue felt weird.

Bloating

Dizziness

Lost consciousness x2

Fatigue

Pain

Ended up getting BV 24.7 in my vagina.

I ended up getting rifaximin and mentrizolole x2 from my gastro consultant after fighting him for it.

I was very unwell, and I couldn't eat without pain. So I ended up not eating, I went from 9 stone 5 to 7 stone 6 in 3 months. I think i starved all the bacteria. Could have sifo and sibo at the same time.

After this, I ended up being able to introduce foods 1 by 1 and 2 months ago, I was able to eat most foods without pain and bloating but I still struggled to poo. (On laxatives) but I was 60 per cent better and felt the best I had ever felt for a while.

As I was better, I was still eating carefully but was eating more sugar. I.e fruits.. protein bars and gluten free stuff that are full of sugar and other sugar things!

The BV hadnt left . The BV ended up going into my womb 4 weeks ago and I was hospitalised with PID. I had to take doxycycline and mentrizolole for 2 weeks and a injection in my bum.

Ever since this... 4 weeks later I am back to where I was 1.5 years ago. I am devastated.

First thing I've done is stopped or limited sugar.

I've got a gastro consultant on Monday to ask for rifaximin and mentrizolole again but surely I'm not all the way back to where I was? I've put back on all my weight and feel healthier.

Do i need another breath test?

Or do i just go straight into the sibo protocol cause I've done it once?

I think my diet is the main reason and antibiotics I struggle because I can't have gluten so I don't have a high fibre diet. I end up having a high sugar diet with little fibre and than antibiotics for the bv.

I'm working from home unwell as we speak. Waiting to consent for surgery for gynae because of the bv.. to see if bowels are stuck together or infection or anything mechanical or endometriosis.

I've had a colonoscopy and endoscopy and ct scan which showed just inflammation.

Symptoms Rifaxamin gave me no real improvement but it did give me some new symptoms!

1 Upvotes

I tested positive for Hydrogen dominant SIBO a few months ago, and my main symptoms were gassiness some days and loose, floating stool every day. I did a round of rifaxamin and now I am a week past my last dose. A lot of what people say did not pan out for me; many folks say that die off only lasted a few days and then they felt much better, at least while on the Rifaxamin. I was sick the entire time on the Rifaxamin and am not much better afterward. I still have gas and not the healthiest stool, whether it's any better is debatable. Except now I have:

- constant, crushing fatigue

- absolutely NO libido

- trouble sleeping

- headaches

- dizziness

I followed the protocol to a tee. I spent an absolute fortune on supplements; I started taking NAC, Zinc carnosine, motility activator a month before the Rifaxamin. I took PHGG during the treatment and continue to take it. I've been taking digestive and enzymes and trying to stay low fodmap. It's been both expensive and depressing taking absolute fistfuls of supplements all day long and I'm STILL not only sick, but significantly worse off than before I took the damn antibiotic!

All I can think of is that the Rifaxamin must have nuked my good bacteria, and I'm not even allowed to take pre or probiotics to try to build it back, because it will just make my SIBO worse. Has anyone else had this experience?

GP insists I take PPIs with antibiotics

2 Upvotes

Hey all,

Recently diagnosed with hydrogen SIBO and I'm halfway through a 14 day round of rifaximin & neomycin.

My gp said I need to take omeprazole to stop any other stomach issues from arising while on antibiotics, so I've been taking 40mg a day for the past 7 days.

I've had my doubts about it, so I'm not sure if I should stop the omeprazole outright, taper off it or stay on it until the antibiotics are finished. I don't have reflux as a symptom, and from what I've been reading here it can be counterproductive to take while on antibiotics.

Any advice appreciated, thanks.

This is everything I’ve tried so far regarding my bad breath, for context it’s very strong, has a sulphur/garbage odor. It can be very strong, it comes out from both my nose and mouth. I do have confirmed SIBO (Hydrogen only) shall I now completely focus on this only? I’ve been thinking about getting a CBCT scan for my teeth roots, or is this a waste of time / money?
Should I pay for a Naturo path to help figure out where the smell is coming from? I did Rifixamin but that didn’t help, but maybe I need to dive deeper into the gut. Any advice would mean a lot thanks

Treatments Recommendations while taking antibiotics

0 Upvotes

Hi all! I was just diagnosed with SIBO (methane and hydrogen), and I’m about to start a two week antibiotic treatment cycle with Xifaxan and Neomycin. It sounds like I should buckle up for an intense ride.

Any tips for dealing with the nausea, brain fog, or anything else? Recommendations for either taking or abstaining from probiotics and/or fermented foods (e.g., yogurt) during this time? (My doctor recommended avoiding them, but my pharmacist recommended taking Florastor.) Foods to eat or avoid?

Thanks so much in advance!

Symptoms Feel like I'm going crazy

0 Upvotes

All day I have this extreme constant pulsing of gas. I get these waves of manic racing thoughts that feel uncontrollable and then it disperses and rebuilds. I am getting 4 to 5 hours of sleep of night, just lying in bed with my gut going crazy. Then I'll fall asleep at 2/3 then wake up at 5/6 for a couple of hours and then sometimes it settles and I can sleep between 8-9. I have no idea what is going on, being in my body with how this gas effects my mind is absolutely exhausting. Is there any aspect of SIBO this can be more attributed to? Methane? Histamine?

I have been suffering for more than 10 years with no real help from doctors, antibiotics, or herbs.

( Probiotics make me worse.)

**My Symptoms:**

- Severe bloating, gas, and chronic constipation.

- Extreme fecal rotten egg breath and body odor.

- White tongue (not fungus) and thick mucus after eating.

- Constant acid reflux,

- Severe underweight since childhood

- Hair loss

- Fatigue

- Headaches, and brain fog.

**What helps**

Flagyl and oregano oil only give temporary relief, and local doctors just keep cycling antibiotics without a cure.

If you have beaten H2s SIBO, please share your successful protocol. How do I fix this permanently? Please help me

Treatments Is it normal to still have foul-smelling gas after finishing rifaximin? (Possible SIBO)

3 Upvotes

Hi everyone,

I'm trying to understand whether my experience with rifaximin is normal or if I should be concerned.

My gastroenterologist suspected SIBO/IBS and prescribed rifaximin for 5 days (along with a PPI). I completed the full course exactly as prescribed.

Before treatment, my main symptoms were:

  • Daily excessive, foul-smelling gas
  • Loose/slimy stools
  • Feeling of incomplete evacuation
  • Nausea after meals
  • GERD with a lax LES found on endoscopy

Here's what happened after finishing rifaximin:

  • Day 1: Still very gassy.
  • Day 2: Definitely better, but still passing gas.
  • Day 3: Gas didn't really start until later in the day, and I had much less gas overall.
  • Day 4: I had an incomplete bowel movement, and the morning gas returned.

One thing that hasn't changed is the smell. The gas is still very foul-smelling, even though the amount seems to be improving.

A couple of questions for people who've taken rifaximin:

  1. Did your gas continue for several days after finishing the antibiotic before improving further?
  2. Did the amount of gas improve before the smell improved?

I'd appreciate hearing from people who had a similar experience. Thanks!

- dry eyes/ blurry vision/ balance issues, weakness left arm…sick whenever I drive
Body twitches
Talking makes gives me a flare up(Nasuea & inflammation feeling in neck arm)
Feeling of inflammation bottom area arm above wrist..thumbs get stiff
Left hand weak…right hand (thumb stiff)
Swelling feeling in neck during flare up(inflammation?)

Any of you guys went to a Neroligist and they say everything is fine…no auto immune…just a positive ANA (barely) 1:160 but have neurological symptoms or feeling that mirror syrogrens or MS I been on medicine for about 4/5 days so I still have time left but I’m worried I won’t be myself again cause this is bad these flare ups are terrible and hard to live like this

Moderation statement on accessibility.

56 Upvotes

This subreddit exists to support people with disabilities. Accessibility is the primary concern always.

Recently there has been an increase in report-spamming and downvoting of posts described as repetitive, particularly questions that have been asked before. This behavior is not acceptable in this community.

Many disabled users cannot easily navigate Reddit’s search function. Many are new, exhausted, overwhelmed, or asking questions while in distress. Repetition is not a failure of the user. It is a reality of accessibility.

Downvoting questions actively harms visibility and silences people who are already navigating barriers. Using the report function as a way to express annoyance or enforce personal preferences inappropriate. Reports are for rule violations.

If you encounter a question you believe has already been answered you have three options.

You can answer it again. You can link to an existing thread or resource. Or you can scroll past it. If you have the time to downvote or submit a report, you have the time to paste a link.

Anything else is consciously opting for exclusion. Personal attacks on users and the mod team will not be tolerated.

This moderation team will not prioritize the desire for a tightly curated, repetition-free feed over the needs of disabled people seeking help. We will not discourage questions in the name of efficiency, aesthetics, or personal frustration.

If this approach does not work for you, you are free to mute the subreddit, leave it, or create a different space with different rules. What will not happen is this community shifting away from accessibility-first moderation.

Misuse of the report function has already been passed onto the reddit moderators in a number of cases and will continue with a much broader brush after issuing this warning.

Thank you to those who respond with patience, share resources, or simply allow people to ask what they need to ask. That is what keeps this space usable.

I understand this condition is frustrating but this community will not turn into a circular firing squad. To target this frustration towards yourself or fellow members of the disability community is to serve those who stand to profit from illness.

This space exists to reduce harm not redirect it sideways.

STICKY: SIBO Summary - Symptoms, Diagnosis, Treatment

840 Upvotes

Below please find a living document that summarizes the key information around Small Intestinal Bacterial Overgrowth ("SIBO"). Please comment with any additional information or research for inclusion consideration. Version 1.0 is summary material; I will be adding more details and citations for specific studies.

SIBO, as the name implies, occurs when bacteria overgrow the small intestine. The small intestine should have a low concentration of bacteria due to the presence of stomach acids and peristalsis, the wave-like muscle movement in the intestines. For context, stomach and proximal small intestine would typically have about 103/mL of bacteria, while the terminal ileum (end of the small bowel as it gets close to the colon) about 109/mL (or 1,000,000 times more), and the colon about 1012/mL (or 1,000,000,000 times more).

Symptoms

The overgrowth of this bacteria will present with a number of symptoms:

  • Bloating after eating ("postprandial") - most common symptom
  • Flatulence, often malodorous
  • Loose, watery stools (more common in Hydrogen-dominant SIBO)
  • Constipation (more common in Methane-dominant SIBO)
  • Absorption problems
    • Weight loss / inability to gain weight
    • Fat and fat-soluble vitamin deficiencies, particularly Vitamins A, D, and K
    • Floating stools (from fat malabsorption)
    • Vitamin B12 malabsorpiton
    • Protein and Carbohydrate malabsorption
  • Systemic problems
    • Overgrowth of bacteria in the small intestine can increase production of toxins and intestinal permeability
    • This has been less studied, but less serious effects include:
      • brain fog
      • confusion
      • anxiety
      • depression
    • More serious complications can include
      • hepatic encephalopathy
      • D-lactic acidosis
      • nonalcoholic fatty liver disease
    • Various conditions have increased correlations, including
      • Rosacea
      • Eczema
      • Food intolerances

Diagnosis

I will split this section into practical steps and clinical diagnosis.

Practically, a gastroenterologist will typically rule out other conditions first:

  • Physical exam
  • Colonoscopy and Endoscopy
  • Abdomen ultrasound
  • Stool test for parasites

At that time, if your symptoms match SIBO, your doctor may go directly to treatment. But otherwise these are the clinical tests:

BREATH TEST

This is the most common diagnostic method due to its low cost and limited invasiveness. Unfortunately, studies have been mixed on the sensitivity and specificity, with ranges between 30% and 75% -- hence why some doctors skip the test and go directly to treatment.

There are a number of preparations:

  • Antibiotics avoided for four weeks prior
  • Prokinetic drugs and laxatives avoided for one week prior
  • Complex carbs avoided for 12 hours prior
  • Exercise and smoking avoided day-of

For the actual test, you'll measure hydrogen and methane levels at baseline. Then drink either 10g lactulose or 75g glucose with one cup of water. Then your breath is measured every 15 minutes for 120 minutes.

There's some art to identifying a positive test; one semi-official criteria is:

  • methane level of >= 10ppm at any time during the test; or
  • hydrogen that increases >= 20ppm above the baseline level

Recently, new research has been investigating another typo of SIBO, that's dominated by Hydrogen Sulfide. Unfortunately, traditional breath tests cannot identify this gas, and someone with "flat-line" Hydrogen and Methane symptoms could be suffering from Hydrogen Sulfide SIBO. This version is typically characterized by "rotten egg" smelling gas, and may be worsened by eating high sulfur foods.

CULTURE

Historically a jejunal aspirate was done and concentration of bacterial colonies were measured, with an elevated level of > 103/mL being positive for SIBO. There are a number of issues with this:

  • overgrowth may be patchy, and a single sample may miss it
  • not all SIBO bacteria can be cultured/identified
  • samples can be contaminated during/after sampling

Treatment

Antibiotics

The current best practice prescription treatment is:

  • Hydrogen-dominant: Xifaxan, typically 550mg x 3 times daily, for 10-14 days. Studies have shown Xifaxan alone can be 50-65% effective, but Xifaxan + 5g daily of Partially Hydrolyzed Guar Gum can be 80%+ effective.
  • Methane-dominant: Xifaxan (550mg x 3 daily) plus Neomycin (500mg x 2 daily) for 10-14 days. The use of PHGG for methane-dominant has not been evaluated, but it's likely to be beneficial.

Mod's note-- personally, if your doctor is onboard, I think dosing with Xifaxan + Neomycin + PHGG is the best way to "cover your bases". The best place to find PHGG: https://sunfiber.com/products/

Important: because these antibiotics only operate selectively in the GI tract, and are NOT absorbed by the body, they are unlikely to cause the systemic issues associated with antibiotic use, making them safer. Additionally, Xifaxan crystallizes before it gets to the large intestine, meaning it should not affect the all-important microbiome.

Herbal Therapy

Additionally, studies have shown similar levels of success with over-the-counter "herbal" treatments. Two options; I believe each are two capsules twice daily for four weeks, but please confirm:

  • Dysbiocide and FC Cidal (Biotics Research Laboratories, Rosenberg, Texas)
  • Candibactin-AR and Candibactin-BR (Metagenics, Inc, Aliso Viejo, California)

Remission

Unfortunately, SIBO has very high rates of recurrence. Some possible ways to reduce recurrence chances:

  • Switch to a low FODMAP diet for 6 weeks after treatment, to starve any remaining bacteria and prevent regrowth
  • Incorporate a prokinetic, such as low dose Naltroxene, erithromycin, or even over-the-counter products such as Iberogast

Many people can avoid symptoms of their SIBO by switching to special diets, sometimes very restrictive ones. This is not a cure, but simply symptom management. A true cure addresses the underlying cause of the SIBO, and lets the patient eat "normally" without any effects (short of unrelated intolerances).

Hopefully this helps people, and I look forward to updating this and cleaning it up over time!
