If you do not have skin conditions or are not stimulated by an external agent, you may be suffering from thyroid disease, diabetes ... if it suddenly becomes itchy.

Most people experience itching symptoms, especially during the spring-summer period, when dry skin is dehydrated, irritated by external agents. However, after you scratch or shower, it will improve.

In addition, skin diseases are also a cause of itching, such as eczema, folliculitis ...

Because this phenomenon is common, people often do not take it too seriously. However, if not in the above cases, you should be careful with the following diseases:


Diabetes is one of the most common metabolic diseases. Clinically, the disease is divided into two types, type 1 diabetes and type 2 diabetes, of which type 2 diabetes is more common, accounting for 90% of the total number of patients.

Seek medical attention if you experience unusual itching.

Between 10 and 40% of people with early-stage diabetes have varying degrees of itching. This is because the patient's blood sugar exceeds the norm, stimulating the peripheral nerves of the skin, leading to neurological dysfunction.

In addition, high blood sugar will increase the osmotic pressure of crystals in the blood and part of the water in the tissue will be transferred to the blood. For a long time, this leads to chronic dehydration, which causes symptoms like dry skin and reduced sweating, which also irritate the skin.

Diabetes that develops to a certain extent can also damage the kidneys, leading to kidney failure. The ability of the kidneys to release urea is reduced. A large amount of urea accumulates in the body, when sweat glands are excreted to stimulate the skin, itching symptoms appear.

Hepatobiliary disease

The liver is the organ responsible for secreting bile and the gall bladder is responsible for filtering and excreting bile secretions. Regardless of the organ in question, it will affect bile secretion.

Bile does not flow into the intestines to digest food, large amounts of bilirubin will flow into the bloodstream, leading to symptoms of jaundice. At the same time, bile salts also accumulate under the skin to stimulate the peripheral nerves, the patient develops an itchy feeling.

May be a warning sign of risk of hepatobiliary disease.

Thyroid disease

Thyroid diseases include many types of hyperthyroidism and hypothyroidism. The percentage of women suffering from this disease is higher than that of men.

After hypothyroidism occurs, due to the influence of the secretion of thyroid hormone, the body's metabolism will also slow down. Patients often have symptoms of dry skin, itching ... especially in the winter and spring, the symptoms of itching are clear.

Hyperthyroidism is also a cause of itching, because it can cause skin metabolism disorders, patients will have many symptoms of sweating, skin prone to reproducing bacteria, causing itching.

Moreover, a small number of patients will also experience generalized pruritus or urticaria, the symptoms of skin itching will be aggravated.

Hyperthyroidism is also a cause of itching.


There appears to be no correlation between melanoma and pruritus. But clinically, many cancer patients experience itching, especially those with lymphoma, colorectal cancer and pancreatic cancer.

This condition is related to stimulation of the peripheral nerves of the skin with histamine and proteolytic enzymes produced by tumor cells.

In addition to causing itchy skin, these diseases are often accompanied by other symptoms such as jaundice due to liver and gallbladder disease, thirst and weight loss due to diabetes, thick neck due to thyroid disease ...

Therefore, when itchy skin has no cause, you should go to the hospital in time for a health check, to accurately detect the infected disease (if any).
