cutanea?\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You may have questions like these.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pruritus cutanea (skin pruritus) is a condition in which <mark>itching alone occurs throughout the body or in specific areas<\/mark>, with no visible changes to the skin\u2019s appearance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udcd6 This article covers the four main causes of pruritus cutanea, how it is diagnosed, treatment approaches, and prevention methods.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"i-0\">\ud83d\udd0d What Is Pruritus Cutanea?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Pruritus cutanea is a condition in which <mark>itching occurs without any visible changes to the skin\u2019s appearance<\/mark>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udc69 It is more common in women, and is said to be particularly prevalent among <mark>pregnant individuals, people living with HIV, and those with chronic hepatitis C<\/mark>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Itching may persist for extended periods throughout the body, or may come and go in waves \u2014 <mark>symptoms vary from person to person<\/mark>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83c\udf19 Additionally, <mark>itching may tend to worsen at night<\/mark>, and some people find that it affects their sleep quality.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"i-1\">\u2753 What Causes Pruritus Cutanea?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The main causes of pruritus cutanea include the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\ud83d\udca7 Dry skin<\/li>\n\n\n\n<li>\ud83d\udc8a Medications<\/li>\n\n\n\n<li>\ud83c\udfe5 Internal organ diseases<\/li>\n\n\n\n<li>\ud83c\udf21\ufe0f External factors<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The following sections explain each cause in detail.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"i-2\">\ud83d\udca7 Cause 1: Dry Skin<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><mark>Dry skin<\/mark> is one of the causes of pruritus cutanea. <mark>When dryness weakens the skin\u2019s barrier function, even minor stimuli can more readily trigger itching<\/mark>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If dry skin is likely contributing to pruritus cutanea, the use of a moisturizer is recommended.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dry skin is also commonly seen in people with the following conditions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\ud83d\udd38 Xerosis cutis (dry skin disorder)<\/li>\n\n\n\n<li>\ud83d\udd38 Atopic dermatitis<\/li>\n\n\n\n<li>\ud83d\udd38 Renal failure<\/li>\n\n\n\n<li>\ud83d\udd38 Hemodialysis<\/li>\n\n\n\n<li>\ud83d\udd38 Diabetes<\/li>\n\n\n\n<li>\ud83d\udd38 HIV infection<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In xerosis cutis and atopic dermatitis, <mark>the skin\u2019s barrier function is already weakened, making it easier for moisture to escape and leading to dryness<\/mark>. In people with diabetes, increased urination can reduce the body\u2019s moisture levels, and disruption of the autonomic nervous system may make it harder to sweat, contributing to dry skin.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In people experiencing pruritus cutanea, conditions such as those listed above may be contributing to the dryness.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"i-3\">\ud83d\udc8a Cause 2: Medications<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><mark>Medications<\/mark> are another potential cause of pruritus cutanea. Itching most commonly occurs as <mark>an allergic reaction to a medication<\/mark>, and in many cases symptoms subside once the medication is discontinued.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Examples of medications that may potentially cause itching include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\u26a0\ufe0f Opioid preparations<\/li>\n\n\n\n<li>\u26a0\ufe0f Hormonal agents<\/li>\n\n\n\n<li>\u26a0\ufe0f Diuretics<\/li>\n\n\n\n<li>\u26a0\ufe0f Antipyretic analgesics (pain and fever relievers)<\/li>\n\n\n\n<li>\u26a0\ufe0f Antibacterial agents<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">While this is relatively uncommon, <mark>particular attention should be given to the possibility that medications may be causing itching in older adults who take multiple medications<\/mark>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"i-4\">\ud83c\udfe5 Cause 3: Internal Organ Diseases<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><mark>Internal organ diseases<\/mark> are a third potential cause of pruritus cutanea.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Examples of relevant internal organ diseases include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\ud83e\udec0 Liver disease<\/li>\n\n\n\n<li>\ud83e\udec0 Kidney disease<\/li>\n\n\n\n<li>\ud83e\udec0 Endocrine disorders<\/li>\n\n\n\n<li>\ud83e\udec0 Blood disorders<\/li>\n\n\n\n<li>\ud83e\udec0 Internal malignancies (organ cancers)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For example, it is thought that in <mark>liver disease, an imbalance in the substances within the body that trigger itching leads to the appearance of skin pruritus<\/mark>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Beyond internal organ diseases, gout and diabetes are also recognized as potential causes of pruritus cutanea.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"i-5\">\ud83c\udf21\ufe0f Cause 4: External Factors<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Pruritus cutanea may be triggered by a variety of external factors. Examples of external factors that may contribute include the following:<\/p>\n\n\n<div id=\"id-c0ae81ce-c7c6-4852-9b2c-d379f46b737f\">\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th>External Factor<\/th><th>Details<\/th><\/tr><tr><th>\ud83d\udec1 Bathing<\/th><td>\u00b7 <mark>Water that is too hot<\/mark><br>\u00b7 Scrubbing the skin too vigorously<\/td><\/tr><tr><th>\ud83d\udc55 Clothing<\/th><td>\u00b7 Wool<br>\u00b7 Synthetic fibers<\/td><\/tr><tr><th>\ud83c\udf5b Food<\/th><td>\u00b7 <mark>Hot foods<\/mark><br>\u00b7 <mark>Spicy seasonings (strongly irritating foods)<\/mark><br>\u00b7 Heavily seasoned foods<\/td><\/tr><tr><th>\ud83c\udfe0 Indoor Environment<\/th><td>\u00b7 Extremely high temperature or humidity<br>\u00b7 Extremely low temperature or humidity<\/td><\/tr><tr><th>\ud83d\udca6 Sweat<\/th><td>\u00b7 <mark>Leaving sweat on the skin<\/mark><\/td><\/tr><tr><th>\ud83c\udf7a Alcohol<\/th><td>\u00b7 <mark>Vasodilation caused by alcohol<\/mark><\/td><\/tr><tr><th>\ud83d\ude30 Stress<\/th><td>\u00b7 Psychological stress<\/td><\/tr><\/tbody><\/table><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">To help prevent and manage pruritus cutanea, <mark>it is important to wash the body gently during bathing to reduce irritation to the skin, and to limit alcohol intake<\/mark>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"i-6\">\ud83d\udd2c How Is Pruritus Cutanea Diagnosed?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Pruritus cutanea is diagnosed <mark>primarily through visual examination<\/mark>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, since the condition can be caused not only by dry skin but also by internal organ abnormalities, testing for underlying internal diseases may also be carried out.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Diagnostic tests may include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\ud83d\udc89 Blood tests<\/li>\n\n\n\n<li>\ud83e\uddea Stool tests<\/li>\n\n\n\n<li>\ud83c\udfe5 Contrast-enhanced CT scan<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Blood and stool tests are used to examine blood composition, hormone levels, blood glucose, and other markers to help identify the cause of pruritus cutanea.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A contrast-enhanced CT scan is a type of CT examination in which a contrast agent is injected into the bloodstream to allow for more detailed imaging.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If no cause is identified even after these and other tests, <mark>the possibility of a psychiatric disorder should be considered<\/mark>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"i-7\">\ud83d\udc8a Can Pruritus Cutanea Be Treated with Steroids? Treatment Approaches Explained<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Pruritus cutanea is <mark>primarily treated with oral antihistamines and moisturization<\/mark>. Treatment with steroids is not a common approach.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is because pruritus cutanea is often caused by dry skin. However, <mark>if scratching has led to the development of eczema, steroid treatment may be used<\/mark> in those cases.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Commonly used moisturizers include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\u2705 Heparin-like substances (Hirudoid)<\/li>\n\n\n\n<li>\u2705 Urea-containing preparations (Urepearl)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If these moisturizers do not provide sufficient improvement, <mark>it may be necessary to consider other approaches, such as adjusting lifestyle habits or treating any underlying internal conditions<\/mark>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For more information on the effects and potential side effects of heparin-like substances mentioned above, please refer to the related article below.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Related article: <a href=\"https:\/\/ic-clinic.com\/treatment\/heparinoid\/\" target=\"_blank\" rel=\"noreferrer noopener\">What Are Heparin-Like Substances?

It is also important to rinse away soap thoroughly, and lukewarm water is recommended for rinsing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Additionally, maintaining an appropriate temperature and humidity in your living space can help keep the skin moisturized and may contribute to preventing pruritus cutanea.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"i-9\">\u2753 Frequently Asked Questions about Pruritus Cutanea<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Below, we address some frequently asked questions about pruritus cutanea.<\/p>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1756791521275\"><strong class=\"schema-faq-question\">\ud83e\udd14 Can Pruritus Cutanea in the Genital Area Be Treated?<\/strong> <p class=\"schema-faq-answer\">Even when pruritus cutanea occurs in the genital area, <mark>it can be addressed by identifying and removing the underlying cause<\/mark>.<br>When itching in the genital area is persistent, it is often due to chronic eczema caused by prolonged irritation from underwear or sanitary products, or from sweat or vaginal discharge.<br>For pruritus cutanea in the genital area, wearing underwear with good breathability that is not too tight is considered an effective approach.<br>It is also <mark>important to maintain cleanliness, minimize irritation, and use appropriate topical medications<\/mark>.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1756791533474\"><strong class=\"schema-faq-question\">\ud83c\udf19 Why Does Itching Worsen at Night?<\/strong> <p class=\"schema-faq-answer\">The reason itching from pruritus cutanea tends to worsen at night is that <mark>body temperature rises during the night compared to during the day<\/mark>.<br>When body temperature increases, the activity of the nerves that transmit itching signals becomes more active, intensifying the sensation of itching.<br>Additionally, during the day many people are focused on work or study and may not notice the itching as much, whereas some people find that they become more aware of it at night.<br>There is no treatment approach specifically targeting nighttime pruritus cutanea, and <mark>it is managed through the same treatment methods used for the condition generally<\/mark>.<\/p> <\/div> <\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"i-10\">\ud83c\udfe5 Consult IC Clinic for Pruritus Cutanea Treatment in Tokyo<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Pruritus cutanea is often caused by dry skin; however, <mark>if no dryness is present, the possibility of an underlying internal condition should also be considered<\/mark>, and early medical attention is recommended.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since pruritus cutanea can also be triggered by psychological stress or external factors, <mark>it is important to consider consulting a medical institution even when symptoms are mild<\/mark>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you are experiencing itching or dryness, please consult IC Clinic before symptoms worsen.<\/p>\n\n\n\n<div class=\"wp-block-sgb-message\"><div class=\"memo sng-shadow-0\" style=\"border-radius:0px;background-color:#fff9e6;color:#ffb36b\"><div class=\"memo_ttl dfont\"><span class=\"sng-box-msg__icon\" style=\"background:#ffb36b\"><i class=\"fas fa-pencil-alt\"><\/i><\/span><div class=\"sng-box-msg__title\"><\/div><\/div><div class=\"sng-box-msg__contents\">\n<p class=\"wp-block-paragraph\">\ud83d\udca1 Appointments for \u201cPruritus Cutanea\u201d are available exclusively at the Dermatology Outpatient Department of IC Clinic Shinjuku.<\/p>\n<\/div><\/div><\/div>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-20959078 wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/ic-clinic.b4a.clinic\/clinics\/312\/bookings\/new\/select\/menu\/\">\ud83d\udcc5 IC Clinic Shinjuku \u2014 General Dermatology Outpatient\u3000Online Booking<\/a><\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"i-11\">\ud83d\udccb Detailed Classification and Characteristics of Pruritus Cutanea<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"i-12\">\ud83d\udd0d Generalized Pruritus Cutanea and Localized Pruritus Cutanea<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Pruritus cutanea is broadly classified into two types based on the area affected: generalized pruritus cutanea and localized pruritus cutanea.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83c\udf10 <mark>Generalized pruritus cutanea<\/mark>, as the name suggests, is a condition in which itching occurs throughout the entire body, and is often caused by <mark>internal medical conditions or systemic factors<\/mark>. It frequently occurs against a background of liver disease, kidney disease, endocrine disorders, blood disorders, or malignant tumors, and detailed internal medical examination is often necessary.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udccd <mark>Localized pruritus cutanea<\/mark> is a condition in which itching occurs only in specific areas, and is often caused by <mark>external stimuli or localized factors<\/mark>. Commonly affected areas include the scalp, genital area, and perianal region, each with its own particular causes and management approaches.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"i-13\">\ud83d\udc65 Characteristics of Pruritus Cutanea by Age Group and Sex<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"i-14\">\ud83d\udc74\ud83d\udc75 Pruritus Cutanea in Older Adults<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In older adults, changes in the physiological functions of the skin make pruritus cutanea more likely to develop. Key age-related changes include <mark>decreased sebum secretion, reduced moisture content in the stratum corneum, changes in skin pH, and reduced immune function<\/mark>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Among individuals <mark>aged 65 and over<\/mark> in particular, progression from winter xerotic dermatitis to pruritus cutanea is commonly observed. As many older adults are also managing multiple chronic conditions, <mark>medication-induced pruritus cutanea due to polypharmacy<\/mark> should also be considered.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"i-15\">\ud83e\udd30 Pruritus Cutanea During Pregnancy<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">During pregnancy, hormonal changes make pruritus cutanea more likely to develop. It is <mark>particularly common in the third trimester<\/mark> and may be referred to as pruritus gravidarum.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pruritus cutanea during pregnancy is thought to involve <mark>rapid fluctuations in estrogen and progesterone, intrahepatic cholestasis, skin stretching, and increased circulating blood volume<\/mark>. In most cases, symptoms resolve naturally after delivery; however, appropriate treatment may be necessary if symptoms are severe.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"i-16\">\ud83d\udc76 Pruritus Cutanea in Children<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Pruritus cutanea in childhood has different characteristics from those seen in adults. <mark>Differentiation from atopic dermatitis is particularly important<\/mark>; pruritus cutanea is suspected when there is intense itching with no skin rash present.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In children, scratching behavior <mark>may affect learning and concentration<\/mark>, and sleep disturbances due to nighttime itching can also impact growth and development, making early and appropriate management important.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"i-17\">\ud83c\udf26\ufe0f Seasonal Factors and Pruritus Cutanea<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"i-18\">\u2744\ufe0f Pruritus Cutanea in Winter<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In winter, dry atmospheric conditions combined with heating use lower indoor humidity levels, <mark>increasing transepidermal water loss<\/mark>. Bathing in hot water and friction from heavy clothing can also worsen pruritus cutanea.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Effective winter measures include <mark>keeping indoor humidity between 50\u201360%<\/mark>, <mark>adjusting bath water temperature to 38\u201340\u00b0C<\/mark>, applying moisturizer immediately after bathing, and avoiding direct airflow from heating units.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"i-19\">\u2600\ufe0f Pruritus Cutanea in Summer<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In summer, increased sweating and sebum production, UV exposure, indoor dryness from air conditioning, and sudden temperature changes caused by air conditioning can all contribute to pruritus cutanea.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Summer-specific measures include <mark>frequent removal of sweat<\/mark>, appropriate sun protection, choosing clothing with good moisture absorption and breathability, and <mark>keeping the temperature difference between indoors and outdoors within 5\u00b0C<\/mark>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"i-20\">\ud83e\udde0 Psychological Factors and Pruritus Cutanea<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"i-21\">\ud83d\ude30 The Relationship Between Stress and Pruritus Cutanea<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Psychological stress is one of the important contributing factors to pruritus cutanea. Stress causes <mark>changes in adrenocortical hormone secretion<\/mark>, which affects immune function and makes inflammatory reactions in the skin more likely to occur.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Stress also disrupts the balance of the autonomic nervous system and <mark>increases cutaneous vasodilation and nerve hypersensitivity<\/mark>, intensifying the sensation of itching.
