Who knows where linquan sees the best dermatosis?

Almost everyone will encounter such a problem: it usually itches here or there, and itches where it itches. If you scratch, you can scratch twice until you feel comfortable. In short, there is a unique secret to deal with all kinds of strange itching on the skin-"scratch"!

Most people don't care too much about what is the main cause of itchy skin and what to do after scratching. In fact, itchy skin is an abnormal signal sent by the body to us, so let us pay attention to it.

Skin itching may be caused by these four diseases.

The skin is the largest organ of the human body. Under normal circumstances, the water content of stratum corneum should be around 10%. If it is lower than 10%, the skin will have chapped, itchy and red symptoms.

Winter is the most itchy season of the year. Due to the cold weather and dry climate in winter, the metabolism of human body slows down, and the secretion of sebaceous glands and sweat glands of the skin decreases, and the water content of the corresponding stratum corneum also decreases, resulting in dryness, chapped skin, itching and other discomfort.

In addition, with the growth of age, the middle-aged and elderly people over 40 years old have decreased sebaceous gland secretion function, aging skin, decreased water retention capacity, and are more vulnerable to external stimuli, and often have itchy skin.

In addition to simple skin problems and skin problems caused by age, there are diabetes, hepatobiliary diseases, gynecological inflammation, malignant tumors and so on. It can also cause different degrees of skin itching, so you need to be vigilant.

1, diabetes

On the one hand, diabetic patients are in a state of hyperglycemia for a long time, which will cause osmotic diuresis and make the skin dry and itchy; On the other hand, high blood sugar can damage the nerves, leading to the reduction of sweat discharged by the body and the reduction of skin moisture content, causing dryness and itching.

Skin itching caused by diabetes usually manifests as local or systemic skin itching, which is wandering or paroxysmal, and it is most serious in cold winter and at night.

2. Abnormal thyroid function

Abnormal thyroid function, whether hypothyroidism or hyperthyroidism, will cause itchy skin. When hypothyroidism occurs, the metabolic rate of human body slows down, which is easy to cause mucinous edema, resulting in dry skin, desquamation and itching.

At the onset of hyperthyroidism, due to the increase of basal metabolism, hyperhidrosis and mental stress, the skin is also prone to itching, and some people may have systemic itching or intractable urticaria.

3. Obstructive jaundice

Skin itching caused by obstructive jaundice is the result of stimulating peripheral nerves with bile salts deposited under the skin. When bile secretion encounters obstacles, the pressure in bile duct and capillary bile duct increases and ruptures, which causes the bound bilirubin to return to the blood, leading to the increase of serum bilirubin.

Because bile salts in bile constantly stimulate sensory nerve endings, it will eventually cause itchy skin all over the body.

4. Malignant tumor

Studies have shown that tumor itching can occur without involving the skin. Common malignant tumors that cause skin itching include intestinal cancer, gastric cancer, prostate cancer and ovarian cancer. Among them, the incidence of itching is high in hematological tumors, especially in rare skin lymphoma, and the incidence of itching is almost as high as 100%.

Experts speculate that tumor itching may be related to histamine and some bioactive substances produced by tumor cells. Histamine and bioactive substances will reach the skin with blood circulation, stimulate the sensory nerve endings of the skin, and lead to different degrees of skin itching.

In addition, skin itching is also related to many diseases such as genitourinary system diseases, blood system diseases and central nervous system diseases. So we need to be vigilant.

There are ingenious ways to relieve itching.

Anyone who has experienced skin itching knows that when the skin itches, you can't help scratching it with your hands. The more you scratch, the more it itches. Finally, the skin was scratched and blood was pulled out, but the itching still couldn't stop.

As can be seen from the above, the causes of skin itching are various. What should I do if there is unexplained skin itching?

First of all, we must rule out suspicious factors. If it's not seasonal factors, skin allergies, and nothing to do with the skin itself, then we should consider the skin itching that may be caused by the disease. See a doctor in time, find out the cause, and then prescribe the right medicine.

Secondly, don't scratch the skin before you know what disease causes itching, so as not to cause itching to spread in a wider range.

In addition, do not frequently use alkaline soaps that are too clean, especially in the case of damaged skin, and do not use hormone ointments to avoid depigmentation or pigmentation.

Finally, before going to see a doctor, in order to achieve the purpose of relieving itching, you can use some topical drugs, such as vitamin E milk and vaseline ointment. If the effect is not obvious, you should seek help and seek medical treatment as soon as possible.

In addition, in daily life, in order to avoid and relieve skin itching, we should also do the following:

Wearing cotton close-fitting clothes is beneficial to skin ventilation and avoids the spread of itching.

Bathing times should not be too frequent, especially in dry autumn and winter. Wash 1-2 times a day. Moreover, the water temperature should not be too high, and 35℃-37℃ is appropriate;

Apply body milk or moisturizing cream in time after bathing to accelerate the absorption of water and nutrition;

The fluorine contained in tea has an antipruritic effect. You can wash your hair or wipe your body with warm overnight tea, which can stop itching and prevent eczema.

Avoid spicy food, pay attention to eat less fat and sugar, and eat more foods rich in manganese, vitamin A and vitamin B6.

Skin is the biggest protective layer of human body. Sometimes, itchy skin really makes people want to cry. Although most of the time skin itching is caused by the skin itself, when there is skin itching with unknown reasons, we should pay more attention to it and be alert to the occurrence of diseases.
