I have a problem with halitosis?


Hello Doctor: Four years ago, I started learning to play the trumpet, and I began to experience bad breath around that time (I'm not sure if it's related to playing the trumpet).
I initially thought that stopping would resolve the issue, but after more than two years of not playing, the problem persists.
I visited a gastroenterologist at a major hospital, and the doctor diagnosed me with gastroesophageal reflux disease (GERD).
However, after taking medication for several months, there was no improvement.
Stool tests and an endoscopy did not reveal any issues.
Eventually, the doctor suggested that I lose weight (I know I am significantly overweight), but losing weight is not easy for me, and I stopped taking the medication.

I would like to ask which department I should choose if I want to see a doctor again.
Should I go back to the gastroenterology department? If that doesn't work, what other specialties could I consider to address my problem? (I know my oral hygiene is fine because I regularly visit the dentist, and the bad breath seems to originate from my esophagus.
My mouth often feels bitter, and sweet foods taste sour at times, and I sometimes feel gastric acid secretion.) Please help me with this.
Thank you.

Esophageal and gastrointestinal issues can also cause bad breath.
If your oral health has been evaluated by a dentist and found to be normal, then your discomfort (such as bad breath) may be related to gastroesophageal reflux disease (GERD) and esophagitis.
It is advisable to consult an internist to rule out liver and kidney diseases.
Be patient with the treatment for esophagitis, which may include medications and avoiding foods that stimulate gastric acid secretion, such as sweets, sticky rice dumplings, tobacco, alcohol, and caffeine (including tea and coffee).

Dealing with bad breath, or halitosis, can be a frustrating experience, especially when it seems to persist despite efforts to address it. Given your history and the steps you've already taken, it's important to approach this issue from multiple angles to identify the underlying cause and find an effective solution.

First, it's worth noting that bad breath can stem from various sources, including oral hygiene, dietary choices, gastrointestinal issues, and even systemic health problems. Since you mentioned that you have been diligent about your dental hygiene and have had regular check-ups, we can rule out common oral causes such as cavities, gum disease, or poor oral hygiene.

Your previous consultation with a gastroenterologist led to a diagnosis of gastroesophageal reflux disease (GERD), which can indeed contribute to bad breath. GERD occurs when stomach acid flows back into the esophagus, leading to symptoms like heartburn, sour taste, and potentially bad breath. If the medications prescribed for GERD did not alleviate your symptoms, it may be time to revisit this specialty. You could consider seeking a second opinion from another gastroenterologist, as different doctors may have varying approaches to treatment. They might suggest alternative medications, lifestyle changes, or even further diagnostic tests to assess the severity of your reflux.

In addition to gastroenterology, you might also want to explore the field of otolaryngology (ear, nose, and throat specialists). An ENT specialist can evaluate your upper respiratory tract and sinuses, as post-nasal drip or sinus infections can also contribute to bad breath. They can check for any obstructions or infections that might be causing your symptoms.

Another potential avenue is to consult with a nutritionist or dietitian. Since you mentioned that you have struggled with weight loss, a professional can help you develop a tailored diet plan that not only aids in weight management but also addresses any dietary factors that may be contributing to your bad breath. Certain foods can exacerbate bad breath, and a nutritionist can guide you on what to avoid and what to include in your diet.

Moreover, if you suspect that stress or anxiety might be playing a role in your symptoms, consider speaking with a mental health professional. Stress can affect digestion and exacerbate GERD symptoms, leading to a cycle that perpetuates bad breath.

Lastly, it’s essential to maintain open communication with your healthcare providers. Keep a detailed record of your symptoms, dietary habits, and any changes you notice. This information can be invaluable in helping your doctors pinpoint the cause of your bad breath and develop an effective treatment plan.

In summary, while gastroenterology remains a key specialty to consider, expanding your search to include ENT specialists and nutritionists may provide additional insights and solutions. Addressing lifestyle factors, including weight management and stress reduction, can also play a significant role in improving your overall health and potentially alleviating your bad breath. Don't hesitate to seek further evaluations and advocate for your health until you find a resolution.
