I. Why do people smell when they are old?

The fact is that old people do smell. Zhang Jianglin, chief physician of the Department of Dermatology at Xiangya Hospital of Central South University, said that old people smell is a special smell mainly focused on middle-aged and older people over 50 years old. In fact, this smell is also found in young people, but the rate of occurrence is higher in the elderly, so it is collectively called the "elderly smell".

So why do people have this old man smell when they get older?

There are three main reasons for this:

One is aging. Dr. Chen Xinsheng, a dermatologist at the Guangdong Provincial Hospital of Traditional Chinese Medicine, points out that as we age, our skin also ages. People with oily skin produce 2-nonenal when the oil secreted on their skin is oxidized, and the substance tastes sour and smelly. In contrast, people with dry skin are prone to dry flaking skin, and the flakes shed by bacteria and other microorganisms tend to produce a putrid stench, also known as the old man smell.

In addition, older people are prone to bad breath and constipation problems on a daily basis due to weakened chewing and digestive functions, and these smells together can lead to increased body odor.

The second is disease. As we age, the body's skin resistance decreases, making it more susceptible to skin diseases such as rashes, eczema, and ulcers, which can cause odors to appear on the skin. In addition, many older people also suffer from chronic diseases such as diabetes and uremia, and these diseases also tend to make the body smell bad.

Third, lifestyle habits. Some seniors do not do a good job of cleaning their bodies due to physical inactivity, which also makes them susceptible to body odor.

Two, the body emits these four odors, beware of the onset of disease

When the body appears odorous, you should also pay attention to distinguish what the smell is, and if it is these kinds of odors, you must promptly seek medical attention for examination.

1. The smell of rotten eggs in the mouth - Helicobacter pylori

The smell of rotten eggs in the mouth needs to be alerted to the possibility that it is caused by H. pylori infection. The H. pylori bacteria is one of the important triggers for the development of gastric disease, the initial stage of infection is usually no obvious symptoms, with the development of the disease will gradually appear bad breath, gastric ulcers, gastritis and other problems, and can even evolve into gastric cancer.

2. Rotten apple smell - diabetes

People with diabetes cannot properly use glucose in the body for energy, and the body needs to break down fat to produce energy, and a lot of ketone bodies are produced in the process of decomposition. The ketone bodies accumulate in the body and cause ketoacidosis, which in turn causes shortness of breath, nausea and vomiting, weakness and headaches, and the exhaled gas will have a distinct rotten apple, sweet smell, which can lead to death in severe cases.

3. The smell of ammonia or urine - uremia

Patients with kidney disease may have the smell of ammonia or urine on their bodies. Because the kidneys can not properly metabolize the body's waste and toxins, resulting in a large accumulation of these substances in the body, which in turn will make a person's breath and urine with a distinct odor.

4. Women's private parts have a fishy smell - bacterial vaginitis

Women's private parts themselves have a faint sour smell, but if there is a distinct fishy smell, it is most likely due to bacterial vaginitis, and patients will have increased secretions, itching and burning in their private parts along with the odor.

Three, do 4 things well, or you can avoid the appearance of old people smell

After the appearance of old people smell, you should first determine what causes the appearance of old people smell, if it is simply caused by aging, then you should pay attention to the daily care of the skin, good moisturizing and cleaning work <p>If it is caused by a disease, it is necessary to treat the original disease, and after the original disease is treated, the body odor can be relieved.

Exercise reduces the risk of many chronic diseases and allows the body's organs to function better, preventing odor due to organ damage. It is recommended to exercise at a moderate intensity of >150 per week or 75 minutes of high intensity exercise. Note that exercise must be done as your body allows, and you should not force yourself.

Eating a light diet, with more fresh fruits and vegetables, coarse grains, and less meat, a lot of meat can easily lead to oxidation of body fat, which can aggravate the body odor.

Some elderly people have body odor, which is entirely caused by poor hygiene. They should clean their under-neck, chest, armpits and other sebaceous parts of the body, and change their clothes regularly.

As people get older, it is normal for them to have an elderly smell. When the smell appears, we need to determine the source of the smell and then target the solution. The newest addition to the lineup is the newest addition to the lineup.
