Reasons Your Breath Might Smell Like Poop
An unpleasant odor coming from your mouth can be embarrassing and concerning. In some cases, breath that smells like poop can indicate an underlying health issue. Understanding the possible reasons can help you figure out when to see a doctor.
Gastrointestinal Issues
Problems in the gastrointestinal tract are a common source of foul-smelling breath. Here are some conditions that can make your breath smell like stool:
Gastroesophageal Reflux Disease (GERD)
Stomach acid backs up into the esophagus causing heartburn and foul breath. The stomach contents can include digested food that smells like poop.
Hiatal Hernia
When part of the stomach pushes into the chest through an opening in the diaphragm, food can back up and produce bad breath.
H. Pylori Infection
This bacterial infection in the stomach can cause belching that smells like feces. It's treated with antibiotics.
Gastritis
Inflammation of the stomach lining from things like excess alcohol, NSAIDs, stress or autoimmune disease reduces digestion efficiency, allowing smelly gases to escape.
GI Obstruction
Blockages or narrowing in the esophagus, stomach, or intestines trap and back up stool, creating an odor.
Peptic Ulcer
Ulcers in the stomach or duodenum caused by H. pylori bacteria or anti-inflammatories allow stomach contents to escape into the breath.
Oral Hygiene Issues
Poor dental health can also cause bad breath smelling like poop, including:
Gum Disease
Bacteria buildup from inflamed gums or gingivitis releases foul gases, especially between teeth and from gum pockets.
Abscess
Pus trapped in a tooth abscess or gum abscess produces extremely foul breath until the infection is treated.
Impacted Food
Debris trapped between teeth, on the tongue or in dental work slowly rots and emits a poop-like odor.
Tonsil Stones
Collections of bacteria, food debris and mucus trapped in the tonsils smell like sulfur or feces when released.
Respiratory Tract Issues
Problems in the sinuses, nose or throat can also make breath reek:
Chronic Sinusitis
Long-lasting sinus infections cause pus discharge into the nasal passages and back of the throat, which you swallow or expel in breath.
Postnasal Drip
Excess mucus dripping down the sinuses to the throat from allergies or illness carries odor-causing bacteria.
tonsils
Enlarged, inflamed tonsils with deep crypts collect smelly debris much like tonsil stones.
Lung Infections
Bacterial infections like pneumonia result in mucus secretions from the lungs that make breath smell rotten.
When to See a Doctor
Occasional bad breath that resolves with brushing and mouthwash isn't a concern. But when it smells like feces persistently, schedule an appointment with your doctor. Be prepared to describe when you noticed it, related symptoms, and anything that makes it better or worse. The doctor can help diagnose the cause and provide appropriate treatment.
See a doctor right away if breath with a poop odor is accompanied by:
- Difficulty breathing or swallowing
- Blood in mucus
- Fever, chills, or unexplained weight loss
- Severe pain
- Vomiting blood
These symptoms could indicate a medical emergency requiring swift intervention, like an obstructed bowel, perforated ulcer, or lung abscess.
Treatments for Smelly Breath
Treatment focuses on remedying the underlying cause of the fecal odor. This may include:
Medications
Antibiotics to treat infections, proton pump inhibitors for acid reflux, or corticosteroids to reduce inflammation in chronic sinusitis.
Surgery
Removing obstructions, draining abscesses, or fixing hernias or obstructions through surgery can eliminate bad breath.
Dental Procedures
Root canals, tooth extractions, debridement for gum disease, or removing tonsil stones can resolve oral hygiene issues.
Lifestyle Changes
Dietary modifications, smoking cessation, managing stress, oral hygiene improvement, hydration, and probiotics can help prevent recurrences.
Coping with Fecal Breath Odor
While waiting for treatment to work, be diligent with your oral hygiene. Brush teeth after meals and avoid smelly foods like onions and garlic. Sugar-free mints, gum, or mouthwash can temporarily mask bad breath. Drink plenty of water to prevent dry mouth bacteria buildup. Consider carrying a small atomizer spray of essential oils like peppermint or eucalyptus to freshen breath on the go.
Let your dentist know about any persistent bad breath issues, as they can perform a clinical exam and offer tips to reduce odor between doctor visits. With the right diagnosis and treatment plan, you can get your breath smelling better in no time.
