Chronic Halitosis Investigation and Struggles

8/9/2025, 7:01:12 AMMale25-34

Demographic Information: Nonbinary individual, 26 years old, 5 feet 5 inches tall, weighing 140 pounds, non-smoker, currently not on any medications. Hello everyone, I am reaching out in a final attempt to address my ongoing issue with chronic bad breath. I have undergone a multitude of tests and imaging procedures, including gastrointestinal (GI), ear, nose, and throat (ENT), as well as dental evaluations, all of which returned normal results. I have also explored various homeopathic treatments, including Traditional Chinese Medicine (TCM). The only abnormal finding was minor reflux, but anti-reflux medications did not alleviate my symptoms. An interesting detail from my breath analysis showed elevated levels of CH3SH (methyl mercaptan), yet tests for methane and sulfur produced no results, which baffled my healthcare providers. I want to emphasize that I have had an extensive range of tests, such as SIBO tests, MRI, MRCP, colonoscopy, endoscopic ultrasound (EUS), barium swallow study, and sinus CT, with all results showing no issues. Additionally, I have had bacterial cultures taken from my throat and nasal passages. I have attempted various lifestyle changes, such as eliminating sugar and altering my dietary choices, in addition to trying several non-conventional approaches and supplements. I’m currently not on any medication and have been tested for Sjögren’s syndrome and other autoimmune diseases with negative results, as well as negative tests for H. pylori and parasites. This condition is not something I have experienced since birth. I have also tried numerous mouth rinses, including chlorine rinse, CHX (Peridex), and Therabreath, as well as oral antibiotic and antifungal treatments, in both rinse and pill forms. I’ve even had a tonsillectomy, which has ruled out that potential source of the problem. This is definitely not a fabricated concern; it’s genuinely affecting my life. In addition to the persistent halitosis, I experience some gastrointestinal symptoms such as reflux (which has not improved with many different medications), feelings of fullness that seem artificial, early satiety, nausea, constipation, and alternating loose stools. However, functionally, I seem fine overall. I have also tried a range of antidepressants to see if the issue is linked to stress or anxiety; unfortunately, they have not made any difference. Once more, this is not an oral hygiene issue; I maintain excellent oral health, as confirmed by my dentist, hygienist, and periodontist. The ENT specialist has also cleared me. In summary: I am dealing with chronic bad breath, with testing from ENT, allergy, and dental sources ruling out possible causes. The breath test highlighted increased production of methyl mercaptan, which may suggest a systemic or gut-related origin. Both hydrogen sulfide and methane levels were found to be zero, while the breath has a methyl mercaptan-related odor.

Chronic bad breath (halitosis) can indeed be challenging to address, especially when you've already undertaken extensive testing and tried numerous treatments with little relief. Given your ongoing symptoms and detailed history, we can focus on exploring some additional avenues to possibly tackle the underlying issues contributing to your chronic halitosis, particularly in relation to gastrointestinal factors.

Summary of Key Points

  1. Persistent Halitosis: Despite extensive testing, the elevated levels of methyl mercaptan indicate a possible metabolic or gastrointestinal source.
  2. Gastrointestinal Symptoms: Your symptoms like reflux, nausea, and altered bowel habits suggest a potential digestive issue that may relate to your halitosis.
  3. Oral Health is Not the Issue: You've confirmed excellent oral hygiene, which rules out common dental causes.

Explanation

Methyl mercaptan is a compound often associated with certain gastrointestinal disorders, including issues with digestion or absorption. Although your tests have returned largely normal, the symptoms you report, including reflux and erratic bowel movements, might hint at an underlying functional gastrointestinal disorder, such as a motility issue or an imbalance in gut bacteria that may not have been fully uncovered by common testing.

Next Steps

  1. Dietary and Symptom Diary: Start tracking your food intake and gastrointestinal symptoms in detail. This can help identify any specific triggers or patterns associated with your halitosis and digestive issues. Focus on noting when the odor seems worse, and the type of foods consumed around that time.

  2. Consider a Low FODMAP Diet: Although food intolerances can vary widely, trying a low FODMAP diet may help. This approach can reduce certain fermentable carbohydrates that give rise to excess gas and digestive distress, potentially alleviating both halitosis and GI symptoms. Consult resources or a nutritionist specializing in digestive health if needed.

  3. Probiotic Trial: If not already tried, consider incorporating a high-quality probiotic that includes strains specifically beneficial for gut health, which might help in restoring balance and relieve some gastrointestinal symptoms.

  4. Hydration and Saliva Production: Ensure you are drinking plenty of water throughout the day, as dehydration can affect breath odor. Consider using products that can stimulate saliva production, like sugar-free gum or mints.

  5. Functional Gastrointestinal Assessment: If not done recently, you might revisit the possibility of functional GI disorders. Symptoms like early satiety and fullness can relate to conditions such as gastroparesis or esophageal dysmotility. A gastroenterologist might suggest more specialized testing like a gastric emptying study or esophageal manometry.

  6. Ongoing Symptom Monitoring: Keep your healthcare providers informed of any changes in symptoms, especially response to dietary changes or the introduction of probiotics. This information can guide future evaluations or interventions.

Reassurance

I understand how deeply frustrating and impactful this issue has been on your life. It's important to be persistent and proactive in finding solutions. If these steps do not lead to improvement, it may be beneficial to seek a specialist in functional gastroenterology or a multidisciplinary team who can provide a comprehensive review of your situation.

Low Ferritin Levels Despite Normal Iron Tests: Possible Explanations

At 39 years old, I have maintained a healthy lifestyle with no smoking, substance abuse, or alcohol consumption. I received a diagnosis of Celiac Disease in June. Additionally, I take 40mg of Omeprazole daily to manage GERD and Barrett's Esophagus. Recently, I had been experiencing intense symptoms of Restless Legs Syndrome (RLS) and significant hair thinning over the past few months. Concerned about these symptoms, I approached my doctor to discuss the possibility of low iron levels, particularly in light of my Celiac condition and the usage of Omeprazole. My physician proceeded to order various tests, which revealed that while my ferritin levels are low, other iron metrics are within normal ranges. What could this indicate? I will provide the test results in the comments below.

Persistent Daily Hives for Two Months

Hello everyone! I'm currently facing difficulties in securing an appointment with a healthcare professional, so in the meantime, I thought I’d reach out for any advice on handling these severe hives that I've been experiencing. I am a 35-year-old female, and for the past two months, I've been suffering from hives that appear all over my body on a daily basis. These welts are numerous and frequently merge into large, swollen areas or manifest as deeper reactions under my skin. I haven’t introduced any new foods or activities into my routine, and I’ve eliminated everything I thought might trigger it. The hives noticeably intensify during the night, causing itchiness on my scalp and in the palms and between my fingers. Although I have tried taking antihistamines, their effects only last a short while, not the full 24 hours as advertised, even for the extra strength formulation. Additionally, I have been experiencing some other health issues that might be related, including hair loss, fatigue, and recently, heart palpitations that disturb my sleep. The hives appear regardless of temperature, though they seem to worsen in hot weather and following showers. I've also observed some mild swelling on the left side of my back, around the rib area and underneath my breast. While I'm unsure if this is connected to the hives, I wanted to mention it just in case. The hives are incredibly bothersome and I would appreciate any suggestions for managing them until I am able to consult with a doctor. Thank you!

When Should I Seek Medical Help for Leg Edema Accompanied by Rashes?

I'm an 18-year-old female currently recovering from anorexia, having started with a BMI of 11 and now estimating a weight gain of over 10 kilograms. Initially, I noticed rashes forming on my feet. During a trip where I did a lot of walking, I observed that these rashes developed into large patches on my calves. Instead of typical pink hues, the patches appeared a vivid red and transformed into a purplish tint a couple of days later. As time progressed, the rashes have migrated to my thighs. The discomfort is quite significant; the affected areas are painful to the touch. I can only tolerate cold water during showers, as even lukewarm water feels like it’s burning my skin. This situation is highly distressing, and I'm uncertain about how to alleviate the swelling effectively and promptly.

Navigating Personal Lab Tests as a Medical Professional

I’m a 33-year-old Medical Lab Scientist employed at a hospital. While it’s common knowledge that we conduct lab tests, my personal testing is kept under wraps. I have an appointment with my doctor soon and I’m concerned about mentioning my self-conducted tests. I typically perform these analyses to keep track of my cholesterol and A1C levels, but I’m feeling a bit anxious about it. My liver function results have been satisfactory, except for my total bilirubin, which has been on a gradual incline. Currently, it sits at 1.3 mg/dL, which is at the higher end of the normal spectrum; last month, it was at 1.2 mg/dL. Moreover, my direct bilirubin has changed from below 0.2 mg/dL to 0.3 mg/dL. I’m also facing low levels of iron at 188 µg/dL and ferritin at 20.48 ng/mL, with a high total iron-binding capacity (TIBC) of 494. Meanwhile, my hemoglobin and hematocrit are within normal ranges, and my red blood cell indices, particularly MCV, are on the upper side of normal. As for my cholesterol profile, all my levels are elevated except for triglycerides. Given my family's medical history, I’ll soon be starting cholesterol medication. However, should I be excessively concerned about the other findings?
