In fact, whole-body itching may be a sign of various internal diseases, particularly liver disease.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Liver and Biliary System<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Cirrhosis, hepatitis (hepatitis B, C, autoimmune), primary biliary cholangitis (PBC), biliary calculus cholangitis, cholangiocarcinoma\u2014these cause itching through accumulation of bile acids. In primary biliary cholangitis particularly, itching often appears as the first symptom, making diagnosis prone to delay.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Expert Insight: Refractory Diseases and Cholestatic Itching<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Numerous complex cases of PBC combined with autoimmune hepatitis (AIH) have been diagnosed and treated, with reports published in English-language medical journals. In these diseases, &#8220;cholestasis&#8221;\u2014impaired bile flow\u2014tends to occur from early stages, manifesting as stubborn whole-body itching that dermatologists cannot explain. Difficult-to-treat autoimmune liver diseases can lurk behind symptoms dismissed as &#8220;just dry skin.&#8221;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Kidneys, Thyroid, Blood Diseases, Diabetes<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">CKD and dialysis patients experience itching from uremic toxin accumulation in skin (&#8220;uremic pruritus&#8221;). Hyperthyroidism causes whole-body itching from increased skin blood flow. Polycythemia vera characteristically causes intense itching after bathing (&#8220;aquagenic pruritus&#8221;). Type 2 diabetes causes itching from peripheral neuropathy and reduced skin immunity.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2\uff0eSkin Changes Suggesting Liver Dysfunction: What Hepatologists Look For<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Jaundice: yellowing of whites of eyes or skin, indicating elevated blood bilirubin<\/li>\n\n\n\n<li>Spider angiomata: red spider-web-like fine blood vessels spreading on chest or face, caused by abnormal estrogen metabolism in the liver<\/li>\n\n\n\n<li>Palmar erythema: redness of palms (particularly at the base of thumb and little finger), indicating hormonal metabolic abnormalities<\/li>\n\n\n\n<li>White nails (Terry&#8217;s nails): most of the nails turning white and cloudy, seen in chronic liver disease with low albumin<\/li>\n\n\n\n<li>Clubbing: fingertips enlarging into drumstick shape, seen in advanced liver and respiratory diseases<\/li>\n\n\n\n<li>Cutaneous telangiectasia: fine blood vessels becoming visible through skin, can indicate progression of cirrhosis<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">3\uff0eSelf-Check Sheet: Confirming Whether Itching Is Coming from Internal Organs<\/h2>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"534\" src=\"https:\/\/saito-cl-liver-regeneration.com\/blog\/wp-content\/uploads\/image-1305.png\" alt=\"\" class=\"wp-image-3794\" srcset=\"https:\/\/saito-cl-liver-regeneration.com\/blog\/wp-content\/uploads\/image-1305.png 800w, https:\/\/saito-cl-liver-regeneration.com\/blog\/wp-content\/uploads\/image-1305-400x267.png 400w, https:\/\/saito-cl-liver-regeneration.com\/blog\/wp-content\/uploads\/image-1305-768x512.png 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/figure>\n<\/div>\n\n\n<ul class=\"wp-block-list\">\n<li>Over-the-counter anti-itch cream\/moisturizer provides no improvement<\/li>\n\n\n\n<li>Itching becomes particularly intense at night (before and after sleep)<\/li>\n\n\n\n<li>Strong itching despite normal skin appearance<\/li>\n\n\n\n<li>Whites of eyes or skin appear yellowish (jaundice)<\/li>\n\n\n\n<li>Urine is dark (beer-colored, orange)<\/li>\n\n\n\n<li>Fatigue, loss of appetite, or weight loss present<\/li>\n\n\n\n<li>Sense of heaviness or discomfort at upper right of abdomen (liver location)<\/li>\n\n\n\n<li>Told at health check that ALT, AST, or \u03b3-GTP is high<\/li>\n\n\n\n<li>Diagnosed as hepatitis B or C carrier<\/li>\n<\/ul>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"534\" src=\"https:\/\/saito-cl-liver-regeneration.com\/blog\/wp-content\/uploads\/image-1307.png\" alt=\"\" class=\"wp-image-3796\" srcset=\"https:\/\/saito-cl-liver-regeneration.com\/blog\/wp-content\/uploads\/image-1307.png 800w, https:\/\/saito-cl-liver-regeneration.com\/blog\/wp-content\/uploads\/image-1307-768x512.png 768w, https:\/\/saito-cl-liver-regeneration.com\/blog\/wp-content\/uploads\/image-1307-400x267.png 400w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/figure>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\">4\uff0eCriteria for Deciding Whether to Seek Medical Attention for Body Itching<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Unexplained itching continuing 2 weeks or more<\/li>\n\n\n\n<li>Itching accompanied by jaundice, dark urine, or fatigue<\/li>\n\n\n\n<li>Itching completely unresponsive to antihistamines<\/li>\n\n\n\n<li>Itching that worsens at bedtime and interferes with sleep<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">5\uff0eA Message from Your Hepatologist<\/h2>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"534\" src=\"https:\/\/saito-cl-liver-regeneration.com\/blog\/wp-content\/uploads\/image-1308.png\" alt=\"\" class=\"wp-image-3797\" srcset=\"https:\/\/saito-cl-liver-regeneration.com\/blog\/wp-content\/uploads\/image-1308.png 800w, https:\/\/saito-cl-liver-regeneration.com\/blog\/wp-content\/uploads\/image-1308-400x267.png 400w, https:\/\/saito-cl-liver-regeneration.com\/blog\/wp-content\/uploads\/image-1308-768x512.png 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">Dismissing body itching as &#8220;just age&#8221; or &#8220;dry skin&#8221; is dangerous.

As a hepatology specialist, I will find the true cause of your &#8220;itching&#8221; and propose the best treatment. Early detection and early treatment is the best way to protect your liver.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><a href=\"https:\/\/saito-cl-liver-regeneration.com\/reservation.html\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" src=\"https:\/\/saito-cl-liver-regeneration.com\/blog\/wp-content\/uploads\/image-310.jpeg\" alt=\"\"\/><\/a><\/figure>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>1\uff0eList of Internal Diseases to Suspect When Your Body Itches &#8220;I assumed my&#8230;<\/p>\n","protected":false},"author":2,"featured_media":3791,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[25,19,20],"class_list":["post-3702","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-english","category-hepatitis","category-liver-cirrhosis"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.2.1 - aioseo.com -->\n\t<meta name=\"description\" content=\"1\uff0eList of Internal Diseases to Suspect When Your Body I\" \/>\n\t<meta name=\"robots\" content=\"max-image-preview:large\" \/>\n\t<meta name=\"author\" content=\"saito-naika\"\/>\n\t<link rel=\"canonical\" href=\"https:\/\/saito-cl-liver-regeneration.com\/blog\/post-3702\/\" \/>\n\t<meta name=\"generator\" content=\"All in One SEO (AIOSEO) 5.0.2.1\" \/>\n\t\t<meta property=\"og:locale\" content=\"ja_JP\" \/>\n\t\t<meta property=\"og:site_name\" content=\"\u809d\u81d3\u518d\u751f\u533b\u7642\u30b5\u30a4\u30c8\u3000\u3055\u3044\u3068\u3046\u5185\u79d1\u30af\u30ea\u30cb\u30c3\u30af\u30d6\u30ed\u30b0 -\" \/>\n\t\t<meta property=\"og:type\" content=\"article\" \/>\n\t\t<meta property=\"og:title\" content=\"What Internal Diseases Should You Suspect When Your Body Itches?
