Could Post-Nasal Drip or Digestive Health Be Behind My Bad Breath?

7/29/2025, 2:30:33 AMMale25-34

29f To provide some background on my situation: I've been experiencing intermittent abdominal discomfort and occasional instances of diarrhea. I've observed that these symptoms often coincide with my menstrual cycle or ovulation, a pattern that began two years ago following the birth of my son. Throughout this period, I have undergone various medical imaging tests, including a CT scan with contrast, ultrasounds, and X-rays. The most recent examination was a specialized ultrasound aimed at detecting deep infiltrating endometriosis, which successfully visualized nearly all of my bowel but yielded no abnormalities (the goal was to check for bowel-related endometriosis). Additionally, I contend with health anxiety, which often leads me to irrationally fear that my symptoms might indicate something serious, like bowel cancer—despite never having had any bleeding. Recently, about one to two months ago, I contracted a virus that has since left me with persistent phlegm that I suspect is sinus-related. Just days ago, while resting, I became aware of an unpleasant odor from my breath, reminiscent of that feeling when you’re hungry, but far more bothersome. Despite my regular oral hygiene routine—which includes brushing, flossing, and tongue scraping—the odor persists. My research online suggests that halitosis can sometimes signal digestive issues, leaving me uncertain whether my condition stems from an underlying digestive problem or if it is simply attributable to the phlegm. If my symptoms are indeed linked to digestive health, what types of gastrointestinal issues typically result in bad breath? Is it possible for complications in the large intestine to contribute to this problem? Thank you for reading about my experience. I appreciate your patience with my lengthy explanation.

Persistent bad breath, or halitosis, can indeed have various underlying causes, including post-nasal drip and gastrointestinal issues. In your case, the combination of your recent upper respiratory symptoms and ongoing digestive discomfort might be contributing to the unpleasant odor you're experiencing.

Explanation:

  1. Post-Nasal Drip: Sinus inflammation can lead to increased mucus production that drains into the throat, which may create an environment for bacteria to grow, resulting in bad breath.

  2. Digestive Health: Gastrointestinal issues, such as acid reflux, food intolerances, or infections, could also lead to bad breath. Conditions that lead to improper digestion can cause food to ferment in the stomach, releasing unpleasant odors.

Your history of intermittent abdominal discomfort and diarrhea, closely associated with your menstrual cycle, also suggests that factors related to your digestive health could be influencing these symptoms. However, since you've undergone thorough testing without abnormalities, it’s important to focus on lifestyle and symptom management.

Next Steps:

  1. Monitor Symptoms: Keep a detailed diary of your symptoms, particularly those related to your digestive health (e.g., types of foods eaten, abdominal discomfort, frequency of diarrhea) and any correlation with your menstrual cycle.

  2. Hydration: Drink plenty of water. Staying hydrated can help maintain a healthy mucus membrane and minimize bad breath.

  3. Nasal Irrigation: Consider using a saline nasal spray or a neti pot to help clear your sinuses. This may reduce post-nasal drip and lessen the associated breath odor.

  4. Diet Review: Pay attention to your diet. Some individuals find that certain foods (like garlic, onions, or dairy) can exacerbate bad breath. You could try eliminating these temporarily to see if there’s an improvement.

  5. Self-Care for Digestion: Focus on consuming smaller, more frequent meals, and include foods rich in fiber. Probiotics (like yogurt or supplements) may also help improve your gut health.

  6. Relaxation Techniques: Since you mentioned health anxiety, incorporating relaxation techniques such as deep breathing, yoga, or meditation can help alleviate some of your concerns.

It's understandable to worry about your symptoms; however, the absence of alarming signs like bleeding is reassuring. If symptoms persist or worsen, considering a follow-up with your healthcare provider might be beneficial to discuss further testing or referral to a specialist if needed. Remember, you’re not alone in this, and taking small, actionable steps can lead to improvement.

Seeking Insights on Persistent GI Issues: A Journey Through Diagnosis

At 26 years old, standing at 5 feet 2 inches tall and weighing 115 pounds, my gastrointestinal troubles trace back to my very first days of life. Right from birth, I struggled with passing meconium, which required assistance. Throughout my childhood, I battled chronic constipation, prompting my mother to frequently administer enemas. By the time I reached grade school, my physician recommended a daily dose of Miralax, which I relied on extensively. Many long hours were spent in the bathroom, grappling with severe gas pain that left me in agony. Eventually, the severity of my constipation lessened, allowing me to cope better with the bloating and discomfort that persisted through my middle and high school years. I underwent an appendectomy at age ten, and shortly thereafter, I began experiencing migraines. Come spring of 2021, I was in my second year working at a plant nursery, where the combination of outdoor heat and my daily routine dramatically shifted my health. Nausea surfaced in the mornings, escalating to frequent vomiting within weeks. My appetite vanished, and despite no noticeable changes in bowel movements, I experienced excruciating abdominal pain one day, culminating in a bowel movement that was the worst I’ve ever encountered—painful, unusual, and accompanied by alarming colors and strange textures. Domestic tensions with insurance delayed my visit to a general practitioner for three months. When I finally managed to see a doctor, I detailed my ongoing nausea, vomiting, abdominal pain, lethargy, lightheadedness, and complete lack of appetite. Following a series of inquiries into possible eating disorders, she referred me to a gastroenterologist and ordered several tests, which included a barium swallow study, ultrasound, and blood tests. Most results came back within normal ranges, although my urinalysis revealed calcium oxalate crystals, and the ultrasound indicated clear kidneys but a cyst on my gallbladder. The swallow study showed evidence of GERD extending into my esophagus, leading to a prescription of omeprazole. My referral to the GI specialist involved additional blood tests for celiac disease and inflammatory bowel disease (IBD), among other medications. They also connected me with a gynecologist to evaluate potential cysts. An endoscopy and colonoscopy were conducted, with checks for microscopic colitis returning negative results, but internal hemorrhoids and gastritis were identified. A CT scan in 2022 revealed fatty infiltration of the liver. After losing track of the MRI follow-up due to staffing changes, I returned seeking assistance from another physician in the group, who left me feeling confused and suggested I may have esophageal sensitivity. Additionally, he proposed an antidepressant, which was not feasible given my psychiatric medications. As my weight dwindled—down 35 pounds in just three months—I turned back to my GP and, after some referrals, received a diagnosis of hypermobile Ehlers-Danlos syndrome (hEDS). I put my gastrointestinal concerns aside while prioritizing my neurological complications and engaging in physical therapy. About a year ago, I revisited a gastroenterologist as my constipation worsened further, though I had fortunately regained some appetite over the prior two years, enabling me to eat half to a full meal daily, which halted my weight loss. However, I started noticing a significant increase in orange and brown mucus in my stool, sometimes to the extent of having only mucus in my bowel movements. This new specialist prescribed a bowel washout, daily Linzess, and a FODMAP diet. After strictly adhering to these instructions while enduring an uncomfortable experience, my efforts yielded zero positive results. Despite keeping a detailed journal, I returned to my norm, but reintroducing foods led to unpredictable consequences—runny stools for several weeks. Now following my subsequent symptoms, it appeared I began experiencing what seemed to be paradoxical diarrhea. At my follow-up appointment, the doctor concurred and adjusted my Linzess dosage. When I met with the specialist again, he inquired about whether I had conducted another bowel washout post-FODMAP diet, to which I replied I was unaware I needed to do so. He encouraged me to perform another washout and experiment with dosing before our next meeting, warning that if improvements weren't observed, we may need to proceed with a colonoscopy. Currently, my stools are rarely "normal"—approximately one out of every hundred follows the mid-range of the Bristol stool chart, appearing without mucus and sinking instead of floating. The variations in color range widely from pale beige to dark maroon and tend to fluctuate. Daily, I grapple with stomach pain and bloating. With extensive research over the past four to five years, my current gastroenterologist now characterizes my issues as IBS-C. I tested negative for both IBD and celiac disease, but I am keen to discuss the possibility of Hirschsprung’s disease, as I recently learned about my early gastrointestinal struggles through my mother. Although I recognize the chances are slim, I feel compelled to mention it in case a colonoscopy is performed, presenting an opportunity to check for it. I’m questioning if the way my symptoms have developed aligns with typical IBS-C presentations or if my concerns are exaggerated. Nothing thus far has provided relief.

Seeking Guidance on Gastrointestinal Issues

For the past couple of years, I've been grappling with persistent gastrointestinal problems at the age of 35. I've faced: • Frequent diarrhea alongside shifts in stool hue and texture, • Intense discomfort beneath my right rib cage, just below the sternum, to the point of inducing sweating and almost fainting, along with general pain in the liver region. Although the pain has been sporadic, it has notably lessened since I adopted a healthier diet and lost weight. My initial medical evaluations comprised: • Several gallbladder function tests and a gastric emptying assessment—results were normal, • A colonoscopy and endoscopy—found no major issues apart from eosinophilic esophagitis (EOE), • Stool analyses also returned standard results. I was given Dupixent to manage EOE. After five months without significant progress, I transitioned to a stringent clean-eating and exercise program, which led to major relief of symptoms and notable weight loss. --- ### Current Trends & History: • Flare-ups appear to be instigated by overindulging in large or fatty foods, • Episodes typically last from one week to a month, • Adopting healthier eating habits consistently alleviates symptoms, • Over these two years, I've shed fifty pounds through a combination of deliberate dieting and reduced intake during flare-ups, • My weight remains consistent outside of flare periods, and I lead an active lifestyle; however, flare-ups hinder my level of activity, • There are instances of suspected platelet reductions during flare-ups, though this is yet to be confirmed through laboratory tests. --- ### Family Medical Background: • Seven women on my mother’s side have undergone gallbladder removal, • One aunt from my father’s side has also had her gallbladder surgically removed. --- ### Current Medical Perspectives: • A gastroenterologist considered the possibility of non-ulcerative dyspepsia and suggested a low-dose antidepressant, yet referred me to a surgeon, indicating some diagnostic ambiguity, • I halted the antidepressant due to adverse effects. Dietary adjustments provided improvement until I encountered another flare following a rich meal, • The surgeon expressed a 75% likelihood that my gallbladder is to blame, despite normal HIDA scan results, acknowledging that not every case adheres to conventional standards, • Two general practitioners concurred that surgery might be a sensible next step, stating, "If symptoms remain post-surgery, we will have definitively ruled out the gallbladder as a cause." --- ### Recent Discovery: • A gallbladder polyp was identified within the last year, which wasn't present earlier. --- ### Summary of Symptoms (During Episodes): • Diarrhea or narrow, oily stools that are discolored, • Intense nausea, • Discomfort around the liver or upper back, • A strong urge to vomit occurring 2–4 hours after consuming rich or heavy meals, • Severe flatulence, with odors ranging from mild to very pungent, • General sensitivity in the gastrointestinal tract, • Possible drops in platelet count during flare-ups. --- ### Important Patterns Observed: • Posture influences my symptoms significantly: • I feel better when standing or sitting upright, • Symptoms worsen with movement, slouching, or lying sideways, • Using a heating pad on my abdomen provides some relief from the discomfort. --- Other noteworthy sensations include pressure in the gallbladder region and an intense feeling of tightening or contracting in my G.I. tract, akin to experiencing extended bouts of diarrhea without relief. ### Main Inquiry: Considering my symptoms, family medical history, the emergence of a gallbladder polyp, and the challenges in accessing specialists due to my rural location—should I proceed with gallbladder removal, or is it prudent to eliminate other possibilities first?

Digestive Challenges

(Male, 160 lbs, 30 years old, no medications or dietary supplements) I’m reaching out for some guidance regarding my husband, who has been experiencing significant digestive and colon discomfort. Background: Throughout his childhood, he led an incredibly active lifestyle, engaging in sports like lacrosse, along with climbing and hiking. However, at the age of 18, he spent two years in El Salvador, and that’s when his gastrointestinal troubles began. During that time, he faced substantial stress and, I suspect, contracted parasites or developed unusual digestive issues from consuming local food (which was akin to a typical diet there). Upon returning home, he followed a treatment regimen to eliminate the parasites, but I believe that the harm had already been inflicted on his system. Fast forward to the present day—he often wakes up feeling queasy, and his bowel movements are either very soft and small or overly watery and urgent, though the volume he passes on a daily basis is relatively low. His diet is quite healthy; I prepare wholesome, nutrient-dense dinners, and he receives meals at work. Recently, he has started to eat a breakfast of eggs and homemade bread daily. I am increasingly worried about the persistent morning nausea. What suggestions do you all have? Should we consider a colonoscopy? Is it advisable to revisit a gastroenterologist? Or would a holistic method be more beneficial (I suspect stress might play a role too)? Thank you for your insight!

Seeking Insight on My Wife's Gastrointestinal Symptoms

I’m reaching out for advice concerning my wife’s troubling gastrointestinal issues. She is 32 years old, stands 5'3" tall, and weighs 138 pounds. Her medical history includes iron deficiency anemia, slightly elevated cholesterol, and depression. At present, she is taking Feramax at 150 mg and Effexor XR at 150 mg. For the past year, she has been experiencing significant irregularities in her bowel movements. They vary widely—some days they seem normal, but at other times they're either laxative-like or have a thick, muddy texture that makes flushing difficult. There have also been instances of steatorrhea, occasionally mild, characterized by oily-smelling stools that can sometimes be seen after wiping or in the toilet bowl. Adding to her discomfort, we frequently notice streaks of mucus in her stools, with some pieces appearing red in color. These erratic stool patterns are often accompanied by excessive gas and abdominal cramps. Notably, just a few days ago, the cramping intensified to the point where she was sweating profusely, and during this episode, she noticed that the stool itself appeared red, separate from the mucus. She has not experienced any vomiting or fever, and there are no signs of jaundice. While her doctor suggested that her occasional night sweats might be a side effect of Effexor, they have said there has been no weight loss. Blood work shows a normal white blood cell count, but her liver enzyme levels (ALT and ALP) are on the higher side of normal. Despite these concerning symptoms, her doctor has dismissed the possibility of colon cancer due to her age and has opted against a colonoscopy. They suspect hemorrhoids as the primary issue but nonetheless ordered stool occult tests even though visible blood is present, as well as calprotectin and CRP tests. My wife remains anxious about the potential for serious illnesses like colon, bile duct, or pancreatic cancer. What could be the underlying cause of her symptoms? How critical is the situation, and could these symptoms indicate cancer? Any insights would be greatly appreciated.

Intense and Prolonged Ovulation Discomfort

Hello everyone, I’m reaching out for some advice and insights on a situation I’m currently facing. I’m a 29-year-old female, currently at cycle day 19, just past ovulation. For the last couple of days, I’ve been experiencing consistent pain in my lower abdomen. It began as a mild irritation but has escalated to a level akin to severe menstrual cramps—weighty, crampy, and persistent—though thankfully, I haven’t experienced any significant bleeding. I did notice some very light spotting a couple of days ago, but nothing else has followed. The discomfort seems largely localized to the left side, radiating into my hip and leg. Unlike typical cramps that fluctuate, this pain has remained constant, and conventional pain relief methods have not alleviated my symptoms. I’m also dealing with systemic joint flare-ups, gastrointestinal issues reminiscent of my menstrual cycle, and increased discharge that resembles what I normally experience during arousal, even though I’m not in that state at the moment. While I have encountered ovulation pain in the past, it’s generally mild and brief, lasting only a few hours at most. This case, however, feels distinct. If I were on my period, I would easily cancel plans without hesitation, but since that’s not the case, I find myself a bit anxious about these symptoms. I can keep my focus, but the pain is always looming in the background. Additionally, I’ve suffered from sporadic lower back pain over the previous months, which has impacted my mobility. I believe it ties back to pelvic discomfort potentially involving my SI joint. At my last visit with my gynecologist, I was told that I have a slight indication of polycystic ovary syndrome (PCOS), as evidenced by pearl-like formations, although a hormonal panel on day three of my cycle did not confirm PCOS. The results showed low levels of SHBG and elevated PTH, which may be pertinent. Typically, my cycles are very regular, featuring heavy bleeding with significant clotting on day three. Notably, I’ve begun to experience ovulation spotting consistently over the past few months. My health background includes a fibromyalgia diagnosis (which I question), insulin resistance, premenstrual dysphoric disorder (PMDD), and I’ve previously undergone cholecystectomy. My medications consist of statins, omeprazole, and I am currently undergoing a treatment cycle with doxycycline for hidradenitis suppurativa (HS). I also take venlafaxine, Concerta, vitamin D, and folic acid. For managing this recent discomfort, I attempted to take 400 mg of ibuprofen yesterday and found that a combination of 200 mg of paracetamol with 500 mg of dipyrone was largely ineffective as well.
