There is a disease in the body, the nose prophet? Reminder: Odors appear in 4 'places', be alert to the coming of diseases

"Dad, why does Grandpa's room have a bad smell? It smells like mold, it smells so bad"

Hearing what his youngest son said, Mr. Li quickly covered his mouth and said, "A kid talking nonsense, what's the smell!"

Mr. Li, who usually lives in the urban area, took his wife and son back to his hometown when he had time during the holidays. Because he usually only returns to his hometown during the New Year holidays, there are usually two elderly people living in his hometown, so it is inevitable that there will be a little bit in the house. special taste.

As soon as Mr. Li's son entered the house, he covered his nose and said loudly that the house had a very special and unpleasant smell, and asked his father to "deodorize" it quickly.

The grandfather next to him was a little puzzled, and said "what's the smell?", but seeing his grandson's disgusted expression, he finally closed his door tightly, and took out the air freshener and sprayed it a few times.

I believe that many people may have smelled a similar "elderly smell". Generally, you can clearly smell a special smell when you are close to the elderly or in the room where the elderly have lived, but often the elderly cannot smell it. Is there any "principle" to this? Does the so-called "old man smell" really exist?

1. Where does the "old man smell" come from? 3 points or the main cause

First of all, we need to be clear that the elderly do have a special smell.

In 2012, in a study published in the international academic journal "PLOS One", researchers asked evaluators to identify the age of participants by smell. It turned out that the evaluators had difficulty distinguishing between the smells of young and middle-aged people, but could easily tell which smell was from the elderly .

Regarding the source of this smell, there are some conclusions, which are mainly affected by 3 reasons:

• metabolism

The source of the smell of the elderly is related to the change of metabolism. When the age increases, the activity ability decreases, the metabolism slows down, and the 2-nonenal secreted on the skin surface gradually accumulates . And this kind of substance will have a special smell. Once it is not cleaned up in time, it will accumulate more and more, and it will easily produce odor.

• lifestyle of the elderly themselves

The composition of human body odor is very complex. In addition to the differences in sweat gland secretions of different people, it is also affected by food intake and hygiene habits.

Some elderly people have decreased physical strength and decreased willingness to clean. These lifestyles can also lead to the formation of body odor.

• disease impact

When people get old, diseases follow one after another, especially some chronic diseases have more obvious body odor.

For example, diabetic patients can produce ketone bodies during the metabolic process, which smells like rotten apples. Patients with chronic kidney disease and renal failure will have nitrogen-containing substances in their bodies, which will smell fishy.

The "elderly smell" is so special, why can't the elderly smell it?

For the sense of smell, one of the evaluation indicators is the "odor threshold", which is the lowest concentration of odor that can be detected by the human body. The lower the odor threshold, the more sensitive the person's nose.

Studies have found that the odor threshold of the elderly is generally 2-25 times higher than that of young people , that is to say, the olfactory sensitivity of the elderly is getting slower and slower.

What's more, the sense of smell is adaptable, just like people who can't stand the smell of durian, once immersed in it, they will only smell its aroma.

2. Odors appear in 4 "places", or signs of disease

Smell can also judge disease? According to a report published by the BBC, Joy Miner, a nurse from Edinburgh, Scotland, can easily smell Parkinson's syndrome through her sense of smell.

To test whether Parkinson's can really be judged by smell, the researchers sampled 64 subjects and combined special molecules. It was found that: Parkinson's patients do have a special taste, and through the sense of smell, the accuracy rate of judgment is as high as 90% .

There are many physiological factors that may affect body odor, such as glandular secretions, such as secretions from female private parts, body excretions, such as sweat, fart, etc., but some odors may be an early warning of disease:

1. Urine

Although normal urine also has a smell, it is not strong, and if there is a sour smell in the urine, it may indicate pesticide poisoning; if there are rotten apples, it is more common in severe complications of diabetes, diabetic ketoacidosis; if there is a mouse smell smell, it is more common in patients with phenylketonuria.

2. Mouth

An unpleasant odor released from the mouth is most likely related to internal organ diseases.

If there is a putrid smell, it is related to inflammation such as sinusitis and pantiltitis; if the smell is sour, it may be related to gastric pyloric stenosis or obstruction; if the smell of rotten apples is more common in diabetic patients; if the smell of urine is related to chronic renal failure related; rancid smell, it may be related to lung infection and other diseases.

3. Stool

The stool itself also has a foul smell, but it is usually not heavy and goes away in a short time.

However, if the stool emits other peculiar smells, such as fishy smell, it may indicate enteritis; sour smell may be related to abnormal sugar fermentation disease; foul smell may indicate enteritis, chronic pancreatitis, pancreatic cancer, etc.

4. fart

As the saying goes, "Sound farts don't stink, stinky farts don't sound". Generally speaking, the main component of smelly farts is hydrogen sulfide, which is caused by the retention of food such as meat and eggs in the body. The smell is stinky, but not pungent.

If you emit extremely smelly farts, it may be related to intestinal inflammation and gastrointestinal dysfunction . If it is a fart with a fishy smell, there may be gastrointestinal bleeding, or malignant tumor bleeding, erosion , etc.

3. What should I do if I am suspected of being "old man"? Doing 3 points will help improve

"Old man's smell" is a physiological change. Although there is no way to completely eliminate this smell, it can be lightened by changing some living habits.

1. Eat a light diet and rinse your mouth after meals

Reduce the intake of greasy fried food, and eat less fish in moderation. These foods will oxidize the fat in the body and aggravate the odor. Three meals a day, should eat more fruits and vegetables, these foods contain antioxidants, can help remove the smell.

Many of the peculiar smells of the elderly are caused by oral diseases. It is recommended that the elderly should develop the habit of rinsing their mouth or brushing their teeth immediately after meals.

2. Change clothes and bathe frequently

The smell of the elderly is related to "lack of ventilation". Many elderly people neglect to clean themselves, often do not change their close-fitting clothes, or neglect to clean sheets and bedding, etc., resulting in a heavier and heavier smell. It is recommended that close-fitting clothing should be changed every two days, and thermal underwear should be changed every three days. If possible, take a bath at least once every two days.

3. Keep indoor ventilation

The metabolism of the elderly is slow, and the excretion smell is heavy. If you don't pay attention to gout, the smell will stay in the bedroom.

If some elderly people need to take medicine all the year round, the taste and smell of the medicine will be mixed together, and the taste will be stronger. Therefore, if the weather is good, you must remember to open the windows in time for ventilation.

Everyone gets old one day, and this particular smell is probably inevitable for each of us. Therefore, the elderly don't have to feel embarrassed, understand this smell, and develop healthy living habits, so they don't have to worry about the accumulation of peculiar smell.
