Why do some people have strange smells?

Body odor is a special and natural odor emitted by human beings and other limb creatures, which is closely related to human health. In daily life, we often smell all kinds of body odor, and various diseases are often hidden behind some different body odors. The following are 15 common smells: 1. Rotten apple smell When diabetic patients are seriously ill, a large amount of fat oxidizes in the liver to produce ketone bodies, which diffuse into the blood, resulting in the exhaled gas containing acetone, and the exhaled gas containing rotten apple smell. The smell of rotten apples is one of the characteristics of diabetic ketoacidosis. 2, urine odor patients with chronic nephritis or nephropathy, the course of disease progressed to the stage of chronic renal failure (commonly known as uremia), because there is no urine, some toxic substances (such as urea nitrogen, creatinine, etc. ) cannot be excreted in the body and remains in the blood, which will make the gas exhaled by the patient smell like urine or ammonia, which is a signal that the condition is getting worse. In addition, the urine of patients with urachal fistula leaks from the umbilical fistula, and patients with urinary incontinence can't control their urine, and their bodies will also emit unpleasant urine smell. 3, rotten cabbage flavor Due to the lack of tyrosine invertase in the body, tyrosine metabolism is disordered and stays in the blood, and the body will emit a strange smell similar to rotten cabbage. Patients generally show slow growth and development, prone to rickets, abnormal liver function and hypoglycemia, and often have hypoglycemia syncope or convulsion. 4. The fishy smell of fish is mainly found in fishy smell syndrome, which is a congenital recessive genetic disease. Due to the lack of trimethylamine oxidase in human liver, trimethylamine cannot be metabolized by the liver and accumulates in large quantities. A large amount of trimethylamine, a fishy substance, is discharged from the patient's sweat, urine and exhaled gas. 5, liver odor Patients with fulminant hepatitis or severe liver injury caused by other reasons often exhale a special odor, commonly known as liver odor. Because methyl mercaptan and dimethyl disulfide cannot be metabolized by the liver, they are special odors in the body. Liver odor indicates that liver function is seriously damaged, which is a manifestation of critical illness. 6, fecal odor patients with bladder and colon fistula, feces in the intestine can enter the bladder through the fistula and dissolve in urine, so the discharged urine usually has fecal odor. In addition, the feces of patients with urachal fistula leak from the umbilical fistula, and patients with fecal incontinence can't control their own feces, and their bodies will also emit unpleasant odor of feces. 7. Maple sugar flavor, also known as caramel flavor, is the most common smell of patients with maple syrup urine disease. Maple syrup urine disease is an autosomal recessive genetic disease. Its harm is that it can poison brain cells, cause serious damage to brain tissue, make patients' intelligence drop obviously, and even become idiots. 8. The smell of cat urine is common in hyperglycemia, which is a disorder of amino acid metabolism. Patients are characterized by mental retardation, osteoporosis, leukopenia and thrombocytopenia in the blood, and are prone to infection or bleeding. 9, sweaty feet, also known as sweaty foot odor syndrome, may be an autosomal recessive genetic disease. Its main clinical manifestations are special foot sweat odor, mental retardation and ataxia. Due to the abnormal metabolism of short-chain fatty acids, the activity of isoamyl coenzyme A dehydrogenase in vivo disappears, and isoamyl coenzyme A cannot be further oxidized, resulting in the accumulation of isovaleric acid and its derivatives in vivo. The patient's vomit, breath, urine, skin and even blood all give off a special smell, which is cheese or strong sweat. 10, body odor is common in patients with osmidrosis, because sebum secreted by sebaceous glands under the armpit has a special body odor under the action of bacteria. Young adults, sebaceous glands are exuberant, and body odor is particularly heavy. 1 1, garlic smell is common in patients with organophosphorus pesticide poisoning, and exhaled gas and vomit can emit irritating garlic smell. 12, acid sweating is common in patients with fever, such as rheumatic fever or long-term oral antipyretic and analgesic drugs. 13, bad breath The mouth emits an unpleasant smell, which is generally found in digestive tract diseases such as oral inflammation, gastritis and gastric ulcer. 14, the smell of alcohol is the smell of alcohol in the body, or the strong smell of alcohol in the mouth after drinking a lot or getting drunk. 15. Other strange vomiting contents are sour, suggesting that food stays in the stomach for a long time and ferments, which is common in patients with pyloric obstruction or achalasia; The presence of intestinal obstruction should be considered when vomit presents fecal odor; Rotten stools are mostly due to pancreatic insufficiency caused by indigestion or chronic pancreatitis, and foul-smelling stools are common in dysentery patients; Blood smell in sputum is more common in patients with massive hemoptysis, and it is more common in patients with lung abscess or bronchiectasis if there is fishy smell in sputum. In short, when you find yourself or people around you have the above abnormal body odor, you should be alert to the signal that it may be a disease. It is best to go to the hospital for further examination in time, so as to achieve early detection and early treatment, so as not to delay the illness.
