An olfactory hallucination, known as phantosmia, makes you detect smells that aren't in your environment. The odors you notice in phantosmia are different from person to person and may be foul or pleasant.
If you have, you may have experienced phantosmia – the medical name for a smell hallucination. Phantosmia odours are often foul; some people smell faeces or sewage, others describe smelling smoke or chemicals. These episodes can be sparked by a loud noise or change in the flow of air entering your nostrils.
Phantosmia is a condition that causes you to detect smells that aren't actually in your environment. It can happen in one nostril or both — and the odors may be foul or pleasant. Common causes include colds, allergies, nasal polyps and dental issues. Treatment depends on the underlying cause.
It sounds absurd but it can happen in plenty of situations! Several health conditions such as sinus infections, mucus or polyps in the airways, infections in the throat, etc. can result in a bad smell that's coming from within your nose. Sinus infection: Sinusitis is a major culprit when it comes to bad smell in nose.
Rectovaginal fistula
“You're basically having poop inside the vagina,” Dr. Greves says. “It smells really bad.” This will often cause a sewer-like or rotten meat smell, along with an unusual discharge, she says.
Occasionally, this discharge may have a pungent smell associated with it, but more often than not, this isn't the case. Rather, trichomoniasis is the STD that most often produces foul-smelling discharge. Men rarely experience outward symptoms of trich (since the infection exists within the male urethra).
A serious reason you could be having sewer smells is due to a broken sewer line. You can get sewer line breaks by: Cleaning frequently – If you use chemical drain cleaners or hydro-jet your pipes too often (using pressurized water to fix blockages), your lines will become weak and break.
A person with kidney failure may have breath that smells like ammonia or urine. Serious liver disease can make breath smell musty or like garlic and rotten eggs. Compounds that are transported through the blood can also be released through your sweat glands. That can make your armpits and skin smell bad.
Although FMO3 gene variants account for most cases of trimethylaminuria, the condition can also be caused by other factors. The strong body odor may result from an excess of certain chemical compounds in the diet or from an abnormal increase in bacteria that produce trimethylamine in the digestive system.
However, if the smell is genuinely present, it could be due to a hidden source like a clogged vent pipe, a dry P-trap in a floor drain, or even a small sewage leak somewhere in your plumbing. It might be worth checking those areas or getting a professional to take a look.
Chronic sinusitis is a persistent condition, with symptoms that include: Nasal obstruction that blocks airflow in one or both of your nostrils. Thick and/or foul-smelling or tasting nasal discharge or postnasal drip. Loss of smell.
Protein breaks down into amino acids, which the body converts into ammonia. The body then releases this ammonia through urine and sweat, which may produce an odor. Dehydration can also make the sweat smell like ammonia. This is because the body needs water to get rid of ammonia through sweat.
An olfactory hallucination, known as phantosmia, makes you detect smells that aren't in your environment. The odors you notice in phantosmia are different from person to person and may be foul or pleasant.
The Dangers of Hydrogen Sulfide, AKA “Sewer Gas”
A naturally occurring gas, hydrogen sulfide, or “H2S,” is toxic at high concentrations. Prolonged or acute exposure to the gas can cause eye irritation, headache, nausea fatigue, and – in extreme cases – death. Smell Sewer Gas in your building?
A decomposing mouse smells like propane gas or rotting meat.
In the case of liver or kidney disease, your odor may give off a bleach-like smell due to toxin buildup in your body.
GERD, or gastroesophageal reflux disease, can cause a person's breath to smell like feces because the stomach acid backs up into the esophagus. This acidic wash irritates the esophagus, which can cause extreme discomfort as well as foul breath.
A zinc deficiency may occur due to underactive thyroid hormone (hypothyroidism) that produces few thyroid hormones and affect the detoxification process, resulting in body odour.
Odor. The process of foods breaking down in the colon makes poop smell. Foul-smelling stools that float can be a sign that your body isn't effectively absorbing nutrients. If this persists, it could be a sign of a food intolerance, celiac disease or a pancreatic insufficiency.
If you have phantosmia, the odors can vary from smells that almost make you sick to really pleasant scents. But most people with phantosmia tend to detect bad smells. The odors have been described as “burned," "foul," "rotten," "sewage," or "chemical." You may be smelling it from one or both of your nostrils.
Still, it's possible that things like diet, medical conditions or a bacterial buildup on the skin could be causing odor, Kopelman says. Hyperhidrosis, the medical term for excessive sweating, could also contribute, because bacteria thrives in moist environments.
Vent Pipe Clogs
All drain systems in your house must be properly vented to prevent sewage gasses from seeping into your home. A clogged vent pipe can prevent sewer-smelling air from leaving your home. This situation often results in leaking odors, and they typically come from the walls around the vent pipe.
Consider everything that ends up in your drains, especially if you use a lot of products and have a lot of family members using your drains. Other causes of sewer gas odors in your home include a dry P-trap, a loose toilet, or a clogged drain. Another cause of sewer gas could be blocked or clogged vent pipes.
The health risks linked to sewer gas exposure include: Hydrogen sulfide poisoning: Hydrogen sulfide smells like rotten eggs, even in low concentrations. Exposure to low levels of hydrogen sulfide can cause eye and respiratory irritation.
