Why does jaundice cause itching

This disorder Jaundice is obvious, but identifying its cause requires a doctor's examination, blood tests Liver Blood Tests Liver tests are blood tests that represent a noninvasive way to screen for the presence of liver disease for example, hepatitis in donated blood and to measure the severity and progress of A tendency to bruise or to bleed easily, sometimes resulting in a reddish purple rash of tiny dots or larger splotches which indicate bleeding in the skin.

If people have any warning signs, they should see a doctor as soon as possible. People with no warning signs should see a doctor within a few days. Doctors first ask questions about the person's symptoms and medical history. Doctors then do a physical examination. What they find during the history and physical examination often suggests a cause and the tests that may need to be done see table Some Causes and Features of Jaundice Some Causes and Features of Jaundice In jaundice, the skin and whites of the eyes look yellow.

Doctors ask when the jaundice started and how long it has been present. They also ask when urine started to look dark which usually occurs before jaundice develops. People are asked about other symptoms, such as itching, fatigue, changes in stool, and abdominal pain. Doctors are particularly interested in symptoms that suggest a serious cause. For example, sudden loss of appetite, nausea, vomiting, pain in the abdomen, and fever suggest hepatitis, particularly in young people and people with risk factors for hepatitis.

Fever and severe, constant pain in the upper right part of the abdomen suggest acute cholangitis infection of the bile ducts , usually in people with a blockage in a bile duct. Acute cholangitis is considered a medical emergency. Knowing whether family members have also had jaundice or other liver disorders can help doctors identify hereditary liver disorders. Because hepatitis Overview of Hepatitis Hepatitis is inflammation of the liver. Hepatitis can be Acute short-lived read more is a common cause, doctors ask particularly about conditions that increase the risk of hepatitis, such as.

Living in or working at an institution with long-term residents, such as a mental health care facility, prison, or long-term care facility. During the physical examination, doctors look for signs of serious disorders such as fever, very low blood pressure, and a rapid heart rate and for signs that liver function is greatly impaired such as easy bruising, a rash of tiny dots or splotches, or changes in mental function.

They gently press on the abdomen to check for lumps, tenderness, swelling, and other abnormalities, such as an enlarged liver or spleen. Blood tests to evaluate how well the liver is functioning and whether it is damaged liver tests. Usually imaging tests such as ultrasonography Ultrasonography Imaging tests of the liver, gallbladder, and biliary tract include ultrasonography, radionuclide scanning, computed tomography CT , magnetic resonance imaging MRI , endoscopic retrograde cholangiopancreatography Sometimes biopsy Biopsy of the Liver Doctors can obtain a sample of liver tissue during exploratory surgery, but more often they obtain a sample by inserting a hollow needle through the person's skin and into the liver.

This type Liver tests Liver Blood Tests Liver tests are blood tests that represent a noninvasive way to screen for the presence of liver disease for example, hepatitis in donated blood and to measure the severity and progress of These tests help doctors determine whether the cause is liver malfunction or a blocked bile duct.

If a bile duct is blocked, imaging tests, such as ultrasonography, are usually required. Other blood tests are done based on the disorder doctors suspect and the results of the examination and the initial tests. They may include. Examination of a blood sample under a microscope to check for excessive destruction of red blood cells. If imaging is needed, ultrasonography of the abdomen is often done first.

It can usually detect blockages in the bile ducts. If ultrasonography shows a blockage in a bile duct, other tests may be needed to determine the cause. Typically, magnetic resonance cholangiopancreatography MRCP Magnetic Resonance Imaging Imaging tests of the liver, gallbladder, and biliary tract include ultrasonography, radionuclide scanning, computed tomography CT , magnetic resonance imaging MRI , endoscopic retrograde cholangiopancreatography MRCP is MRI of the bile and pancreatic ducts, done with specialized techniques that make the fluid in the ducts appear bright and the surrounding tissues appear dark.

For ERCP, a flexible viewing tube endoscope is inserted through the mouth and into the small intestine, and a radiopaque contrast agent is injected through the tube into the bile and pancreatic ducts. Then x-rays are taken. When available, MRCP is usually preferred because it is just as accurate and is safer. But ERCP may be used because it enables doctors to take a biopsy sample, remove a gallstone, or do other procedures.

Occasionally, liver biopsy Biopsy of the Liver Doctors can obtain a sample of liver tissue during exploratory surgery, but more often they obtain a sample by inserting a hollow needle through the person's skin and into the liver.

It may be done when certain causes such as viral hepatitis, use of a drug, or exposure to a toxin are suspected or when the diagnosis is unclear after doctors have the results of other tests. Laparoscopy Laparoscopy Laparoscopy is an examination of the abdominal cavity using a fiberoptic instrument inserted through the abdominal wall.

This is a surgical procedure done in an operating room. People are given For this procedure, doctors make a small incision just below the navel and insert a viewing tube laparoscope to examine the liver and gallbladder directly. Rarely, a larger incision is needed a procedure called laparotomy.

For a blocked bile duct, a procedure to open it such as endoscopic retrograde cholangiopancreatography [ ERCP Endoscopic Retrograde Cholangiopancreatography Imaging tests of the liver, gallbladder, and biliary tract include ultrasonography, radionuclide scanning, computed tomography CT , magnetic resonance imaging MRI , endoscopic retrograde cholangiopancreatography The underlying disorder and any problems it causes are treated as needed.

If jaundice is due to acute viral hepatitis Overview of Acute Viral Hepatitis Acute viral hepatitis is inflammation of the liver caused by infection with one of the five hepatitis viruses. In most people, the inflammation begins suddenly and lasts only a few weeks. However, hepatitis may become chronic, even if the jaundice disappears. Usually, itching gradually disappears as the liver's condition improves. If itching is bothersome, taking cholestyramine by mouth may help.

However, cholestyramine is ineffective when a bile duct is completely blocked. If the cause is a blocked bile duct, a procedure may be done to open the bile duct. This procedure can usually be done during ERCP, using instruments threaded through the endoscope Endoscopic Retrograde Cholangiopancreatography Imaging tests of the liver, gallbladder, and biliary tract include ultrasonography, radionuclide scanning, computed tomography CT , magnetic resonance imaging MRI , endoscopic retrograde cholangiopancreatography In older people, the disorder causing jaundice may not cause the same symptoms as it typically does in younger people, or the symptoms may be milder or harder to recognize.

For example, if older people have acute viral hepatitis, they often have much less abdominal pain than younger people.

When older people become confused, doctors may mistakenly diagnose dementia and not realize that the cause is hepatic encephalopathy Hepatic Encephalopathy Hepatic encephalopathy is deterioration of brain function that occurs in people with severe liver disease because toxic substances normally removed by the liver build up in the blood and reach That is, doctors may not realize that brain function is deteriorating because the liver is unable to remove toxic substances from the blood as it usually does and, thus, the toxic substances can reach the brain.

In older people, jaundice usually results from a blockage in the bile ducts, and the blockage is more likely to be cancer. Doctors suspect that the blockage is cancer when older people have lost weight, have only mild itching, have no abdominal pain, and have a lump in the abdomen. Therefore, serotonin reuptake inhibitors may also help manage pruritis. It is difficult to determine the immediate cause of itching, but there are many self-care treatments and precautionary measures that can help.

Prescription oral medications may also help. These include :. This product can moisturize and cool the skin. Although itchy skin is typically harmless and treatable, it can sometimes be a symptom of liver disease. People who already have liver disease and experience itching should also get medical advice. However, it is not an indication of disease progression or outlook.

It is important to remember that itching is not always a direct symptom or result of liver disease. Other liver disease symptoms include fatigue, bruises or bleeding, spider veins, yellow skin or eyes, and unusual breath. Although itching can occur during pregnancy due to stretching skin and hormones, it can also result from a liver condition called intrahepatic cholestasis of pregnancy ICP.

This may be an option even if your liver is still functioning.

Liver failure is sometimes accompanied by itching. But you can develop problem itching early on, before you even know you have liver disease. In fact, pruritis can develop at any point in liver disease. This symptom alone says nothing about liver disease severity, progression, or prognosis. Itching associated with liver disease tends to be worse in the late evening and during the night. Some people may itch in one area, such as a limb, the soles of their feet, or the palms of their hands, while others experience an all-over itch.

However, you can develop visible irritation, redness, and infection due to excessive scratching. A severe case of dry skin xerosis cutis can certainly lead to troublesome itching.
