Bad Breath Smells Like Poop - Causes and Treatments

Understanding Bad Breath That Smells Like Feces

Unpleasant breath odor is an embarrassing problem that many people face. But when your bad breath smells like poop or feces, it can be mortifying. This troubling symptom is usually a sign of an underlying health condition that needs attention.

What Causes Fecal Breath Odor

There are a few possible causes for breath that smells like stool:

• Gingivitis or periodontal disease
• Post-nasal drip
• Chronic sinus infections
• Throat or lung infections
• Acid reflux or GERD
• Constipation or bowel obstruction
• Metabolic disorders like diabetic ketoacidosis

Gingivitis and Periodontal Disease

Gingivitis is inflammation of the gums often caused by plaque buildup. If left untreated, it can progress to periodontitis - serious gum infection affecting the tissues and bone structures supporting the teeth. As the pockets around teeth fill with bacteria and pus, they can rupture and release foul-smelling gases into the breath. This is a common source of oral malodor.

Post-Nasal Drip and Sinus Infections

Mucus dripping down the back of the throat from the sinuses is called post-nasal drip. It can make you feel like you need to clear your throat often. Sinus infections also involve an overproduction of mucus that builds up and starts to smell bad. As you breathe out, these odors can make it seem like your breath smells like poop.

Lung and Throat Infections

Infections in the lungs such as pneumonia or bronchitis cause excess mucus production and inflammation. This environment allows bacteria to multiply, emitting foul sulfur gases. Infections in the throat like tonsillitis or strep throat also release stinky breath. With any infection, pus often forms which can smell quite unpleasant when expelled into the mouth and breathed out.

Acid Reflux and Other Digestive Disorders

Problems with digestion can also make your breath smell like feces or poop:

• Acid reflux or GERD causes stomach acid and contents to rise up into the throat and mouth which can smell quite foul.
• A bowel obstruction may block digestion, causing a buildup of rotting food that releases gases as it breaks down. Signs include infrequent bowel movements, cramping and stomach pain.
• In rare cases, an abnormal opening forms between part of the large intestines and another nearby organ or skin surface. Called a fistula, this allows escaping fecal material to emerge near the mouth.

Metabolic Disorders

In people with diabetes, a serious condition called ketoacidosis can occur when insulin levels get too low. The body starts breaking down fats for fuel, forming ketones and acids that make the breath smell sweet or even fruity. However, it also smells foul and is a potentially life-threatening emergency requiring immediate medical treatment.

How to Diagnose the Cause

To get to the root of whats behind foul fecal breath odor, visit your doctor or dentist. They will ask about your symptoms and medical history and perform an exam of your mouth, nose, throat and lungs. Tests might include:

• Blood and urine tests to check for infections
• Stool analysis
• Endoscopy to examine the stomach and upper digestive system
• Imaging tests like X-rays, CT or MRI scans to visualize internal structures

Once the underlying cause is determined, proper treatment can be provided. The odor should subside as you recover. Call your doctor promptly about any major change in your breath odor.

Treatments for Bad Breath That Smells Like Stool

Oral Hygiene and Gum Disease Treatments

Practicing good oral hygiene every day can help prevent and treat bad breath from gum problems and dental infections. Brush at least twice and floss once daily. Get professional teeth cleanings every 6 months. See your dentist about options to treat gum disease such as deep cleaning, gum surgery or special mouth rinses.

Medications and Home Remedies

If post-nasal drip, acid reflux, or infections are the culprit, medications can tackle those problems and indirectly fix bad breath too. Antibiotics treat bacterial infections while decongestants thin mucus. Antacids neutralize stomach acids and proton pump inhibitors reduce acid production. Your doctor may prescribe combinations of these medications. Additionally:

• Gargle frequently with salt water
• Use throat lozenges and cough drops
• Drink plenty of water and non-acidic juices like pear nectar
• Avoid dairy, caffeine, alcohol and acidic foods

Seeking Medical Care

Rarely, severely foul smelling breath requires hospitalization for more aggressive treatment. This includes intravenous antibiotics for infection, bypass surgery for bowel obstructions, or emergency care for diabetic ketoacidosis. Follow your doctors treatment plan closely to prevent complications.

Preventing Bad Breath That Smells Like Feces

While you cant avoid every instance of foul smelling breath, you can take steps to minimize recurrences:

• Brush and floss thoroughly each day
• Scrape your tongue when brushing
• Get regular dental cleanings and exams
• Treat gum disease promptly if diagnosed
• Stay hydrated by drinking lots of water
• Limit tobacco, alcohol and sugary or acidic foods
• Practice good sinus care like saline spray or irrigation
• Manage medical conditions like diabetes or GERD

Even with great hygiene, most people deal with bad breath occasionally. But when your breath smells distinctly like poop or feces, don't ignore this red flag. Have your doctor check for underlying illness and follow treatment guidelines closely. Swift action can help nip smelly breath in the bud and prevent complications.
