In life, there are some health pseudo-knowledge passed down by word of mouth, which has become a superstitious "health maxim" for many people. Today, experts from various disciplines in Beijing Ditan Hospital will popularize some common health knowledge misunderstandings in life, come and see if you have been "tricked"!

Can eating raw fish cure diseases?

The Department of Hepatology has treated cases of liver and kidney damage caused by eating raw fish gallbladder poisoning, and these patients are all because they believe in the home remedies that "eating raw fish gallbladder can clear away heat and detoxify, clear the liver and brighten the eyes". In fact, the carp sulfate sodium, histamine, hydrocyanic acid, bile acid, etc. in the bile of fish can cause damage to human tissues. Therefore, eating raw fish gallbladder not only cannot treat diseases, but also cause poisoning, resulting in damage to multiple organs and even death.

Do you need to be vegetarian?

Eating a large amount of high-fat and high-cholesterol foods can easily induce gallstones and cholecystitis, so some gallstone patients think that they should eat vegetarian for a long time, which is a wrong concept.

If you eat a vegetarian diet for a long time, it will cause the body to be deficient in fat-soluble vitamins. It can also cause insufficient intake of animal protein and trace elements, which can lead to hypoproteinemia, bleeding and edema of the lower limbs, and even palpitations, fatigue, emaciation, anemia, etc. In addition, fat can promote the secretion of bile, but if you eat a vegetarian diet for a long time, it is easy to cause a decrease in bile secretion and excretion, resulting in the retention, concentration and accumulation of bile in the gallbladder, and the concentrated bile repeatedly stimulates the gallbladder wall, which may lead to the formation of gallstones or aggravate the progression of gallstones.

Therefore, the most important thing is to eat a balanced diet, and for gallstone patients, the diet should be mainly low-fat and low-cholesterol foods.

Can holding your breath for 30 seconds test your lung health?

Whether you can hold your breath for 30 seconds is not necessarily related to lung health. The health of the lungs depends on a variety of factors, and it is rare for doctors to judge the health of a person's lungs simply by holding their breath or climbing a stairs. The lungs are composed of many alveoli, and the examination mainly includes the morphology of the lungs and chest expansion, lung function, and pulmonary vascularity, and lung health generally requires pulmonary function tests.

When you have respiratory symptoms or other discomfort, you should be tested accordingly, and you should not believe the rumors that you can check for lung diseases by holding your breath for 30 seconds.

Is a vegetarian diet better for controlling blood lipids?

A vegetarian diet may lead to insufficient intake of certain B vitamins, which are closely related to the metabolism of fats, carbohydrates, and proteins. B vitamins are mainly found in milk, eggs, liver, and fish. Therefore, if you only consume a vegetarian diet, you may suffer from B vitamin deficiency, which may cause fat metabolism disorders, which may also be one of the factors of dyslipidemia.

Therefore, if you suffer from hyperlipidemia, the principle of "less meat and more vegetarian" should be taken as the principle, rather than a complete vegetarian diet, so as to achieve the purpose of scientifically lowering blood lipids and balancing the diet.

Pick up a white hair and grow ten?

There is no scientific basis for the claim that "gray hair is getting more and more plucked". The number of hair follicles a person has is determined at birth, and pulling out hair does not increase the number of hair follicles and hair, nor does it increase gray hair. In that case, can you safely pluck gray hair? Of course not.

Doctors do not advocate frequent plucking of gray hair, especially if there is a lot of gray hair, because this does not reduce the appearance of gray hair, and can also damage hair follicles and even cause folliculitis. Recurrent episodes of folliculitis can cause hair follicles to never grow new hair, resulting in "baldness."

Is prostatitis a geriatric disease?

This is a false statement. Prostatitis is a common urinary disease, especially in men under 50 years of age. Young adulthood is a period of vigorous male sexual function, frequent sexual activity, and repeated stimulation of sexual excitement can easily lead to repeated congestion of the prostate gland and induce inflammation.

In addition, the young adult period is the most vigorous period for prostate secretion, which provides good conditions for the growth and reproduction of bacteria. If personal hygiene is not taken into account, the immune system is weakened, or infections occur in other adjacent areas, pathogens can enter the prostate, causing acute and chronic inflammation.

Do lung nodules have to become lung cancer?

In fact, the vast majority of lung nodules, especially small nodules and micronodules, are benign and do not develop into lung cancer. Most patients with pulmonary nodules have no symptoms and are discovered incidentally during physical examination. A foreign study on lung cancer screening showed that among the 2 patients with lung nodules found in physical examination, only 0 patients with malignant nodules were malignant, accounting for about 0.0%. Judging from the outpatient situation in China, most patients have also been diagnosed with benign pulmonary nodules.

Therefore, if you find that you don't need to be overly anxious about pulmonary nodules, it is the most effective and appropriate way to deal with them by asking a professional thoracic surgeon to evaluate and diagnose.

Autumn-winter infusion ability to prevent vascular disease?

Some elderly people are accustomed to transfusing drugs to promote blood circulation and eliminate blood stasis in autumn and winter to prevent cerebrovascular disease, but in fact, this is all a misunderstanding. Infusion not only has no effect on the prevention of cerebrovascular disease, but also has a potential infusion reaction because it is administered directly in the blood through intrablood.

The correct prevention of cerebrovascular disease is to develop good living habits, including regular monitoring of blood pressure, blood lipids, and blood sugar changes, paying attention to keeping warm, eating reasonably, quitting smoking and limiting alcohol, drinking more water, and ensuring fluid balance to reduce the occurrence of cerebrovascular disease.

Drink more bone broth after a fracture to help recovery?

Can drinking bone broth be good for recovery, treatment of osteoporosis or fractures? This view is actually a misunderstanding in life. The main content of big bone broth is fat, and fat does not directly help us treat osteoporosis and fractures, and has less positive effects on recovery and treatment of osteoporosis or fractures. In terms of nutrition, for the elderly and other people with weak constitutions, they can help increase the calcium content in the body and promote the health of the body by drinking more milk and regularly intaking vitamin D and calcium tablets.

Washing is healthier?

I'm sure you'll hear this statement a lot. Some people believe that daily vaginal irrigation is cleaner and can prevent vaginitis. In fact, the normal pH value of the vagina is 4.0~0.0, and the vagina of a healthy woman is the same as the oral cavity, and there are dozens of bacteria breeding at ordinary times, but they are safe and sound due to the existence of the vaginal "guard".

The most important "little guard" of the vagina is lactobacilli, which can break down glycogen in vaginal cells into lactic acid, so that the vagina maintains a certain acidity, thereby limiting the reproduction of pathogenic bacteria. In fact, it is good to rinse the vulva with water, but too much rinsing will destroy the microecology of the vagina, destroy the acidic environment, and make it easier to get vaginitis.

Should patients with kidney disease eat low sodium?

Patients should reduce their sodium intake, so it is better to consume low-sodium salt, which sounds true, but it is actually not! The reason why "low sodium salt" is low in sodium is because it is mixed with 30% potassium. Although the sodium intake is low, the potassium content is high, which can easily lead to hyperkalemia. Therefore, although patients with kidney disease should consume less sodium, it is better to reduce salt intake from the diet.

Does general anesthesia affect intelligence?

"General anesthesia affects intelligence!" This is a traditional and classic misconception, and one that is often asked by anesthesiologists. In fact, there is no scientific evidence to prove that general anesthesia has an effect on intelligence. Anesthetic drugs, like any other drug, have a metabolic process. Over time, the general anesthetic drug is completely excreted from the body through various routes without leaving residue in the body.

With the development of medicine, general anesthesia is now gradually tending to use anesthetic drugs with short-term effect, reliable effect and mild adverse reactions, and these drugs will be quickly eliminated by the body after surgery.
