1) You may have some tooth or gum inflammation or infection. 2) Your nose may be picking up residual odors from garments or materials washed with bleach. If it's in your clothing others may not necessarily smell it. 3) Many unusual odors may be associated with sinus infections.
An olfactory hallucination (phantosmia) makes you detect smells that aren't really there in your environment. The odors you notice in phantosmia are different from person to person and may be foul or pleasant. You may notice the smells in one or both 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.
If you have diabetes, a change in body odor could be a sign of diabetes-related ketoacidosis. High ketone levels cause your blood to become acidic and your body odor to be fruity. In the case of liver or kidney disease, your odor may give off a bleach-like smell due to toxin buildup in your body.
Breathing high amounts of chlorine gas can lead to a build-up of fluid in the lungs and severe shortness of breath that could lead to death if untreated. Immediately or within a few hours after breathing chlorine gas, the lungs can become irritated, causing coughing and/or shortness of breath.
However, some people experience a change to their sense of smell about three to four months following infection. People report certain things—like food or body odor—smelling like garbage, rotten eggs, or chemicals. This altered sense of smell is called parosmia.
An infected sinus releases mucus that has a foul odor. The mucus drains to the back of your throat, resulting in bad breath. Also, when you have a sinus infection, there may be bacteria trapped in the nasal cavities, which produces an unpleasant smell.
Trimethylaminuria is a disorder in which the body is unable to break down trimethylamine, a chemical compound that has a pungent odor. Trimethylamine has been described as smelling like rotten or decaying fish.
Non-neuronal expression of SARS-CoV-2 entry genes in the olfactory system suggests mechanisms underlying COVID-19-associated anosmia. Altered olfactory function is a common symptom of COVID-19, but its etiology is unknown.
Phantosmia, which is an olfactory hallucination, sometimes occurs with anxiety. It can cause you to smell something that isn't there, or rather, a neutral smell becomes unpleasant. Most often, this bizarre sensation is caused by antidepressants or withdrawal from them. However, sometimes it's associated with anxiety.
Thyroid problems.
Occasionally, an overactive thyroid can also cause body odor. This is because the patient tends to sweat excessively due to the hyper-functioning thyroid gland. This condition can also be ruled out by physical examination and blood studies.
Severely ill patients often have characteristic smells. Patients with diabetic ketoacidosis have the fruity smell of ketones, although a substantial number of people are unable to detect this. Foetor hepaticus is a feature of severe liver disease; a sweet and musty smell both on the breath and in urine.
Some people with inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis (UC), experience changes in body odor as a result of the disease. Although they are common symptoms, these odors can make a person feel anxious, affect their self-esteem, and even make them wary of leaving the house.
Cavities can trap bacteria and release unpleasant gasses like sulfur as it breaks down. These gasses can travel through small holes in the back of the mouth that connect to the sinuses and cause a bad smell in the nose.
During a sinus infection, however, your sinuses become swollen and potentially congested. This can trap mucus and all that it has filtered from the air, which can, in turn, lead to some rather unpleasant odors.
Chronic kidney disease (CKD) is one possible cause of having an ammonia taste in your mouth, sometimes called “ammonia breath.” Some people describe ammonia breath as having a metallic taste, while others have reported that it smells similar to urine.
Smelling ammonia usually happens towards the end of a long or challenging workout and is a strong indicator that you have been burning protein as fuel.
Parosmia is a change in your sense of smell. Many people experience parosmia as perceiving a previously pleasant scent as suddenly foul or unbearable. It typically develops after you've had an infection, head trauma, chemical exposure, or other health condition.
Parosmia is a condition where a person's sense of smell no longer works correctly. Caused by infections like COVID-19, head injuries, or other neurological conditions, this loss of smell can be an inconvenience for some— and a significant problem for the quality of life of others.
Smelling of the breath is common after having certain food or in the morning, but with people suffering from fatty liver conditions, it remains throughout the day. The breath may have a distinct sulfur and musty smell throughout the day. It is an obvious sign of fatty liver disease and should not be ignored.
