Acholic Stools Dark Urine (DIY Project Download)

However, although pale stools and dark urine are a feature of biliary obstruction, they can occur transiently in many acute hepatic illnesses and are therefore not a reliable clinical feature to distinguish obstruction from hepatic causes of jaundice. If someone presents with dark urine and clay-colored stool, how is that possible? No Urobilinogen in the bile (pale stool) and it’s not there for enterohepatic reuptake so it never makes it back to the kidneys. Pale stools and dark urine – pale stools occur as no bilirubin reaches the gastrointestinal tract and dark urine results from reflux of conjugated bilirubin into blood which is excreted in the urine.

acholic stools dark urine 2Urobilinogen is a colourless by-product of bilirubin reduction. It is formed in the intestines by bacterial action on bilirubin. These mechanisms are responsible for the dark urine and pale stools observed in biliary obstruction. Low urine urobilinogen may result from complete obstructive jaundice or treatment with broad-spectrum antibiotics, which destroy the intestinal bacterial flora. Dark urine can be the result of a problem with the liver or bile ducts, especially if accompanied by lighter-than-normal stools. Dark urine and light stools are one of the ways to detect jaundice, when there is too much bilirubin in the body. Urine is usually dark because of the bilirubin excreted through the kidneys.

Babies with biliary atresia also have very pale or gray (acholic) stools. Bile gives stools their usual yellow, green or brown color. This can make their urine darker than normal. If a baby with biliary atresia does not get treatment within the first couple of months after birth, scarring of the liver (cirrhosis) can occur. Pale stool is stool (feces) that is unusually light in color instead of medium to dark brown. Acholic is the medical term that refers to clay-colored stool. Symptoms of hepatitis include dark urine, abdominal pain, loss of appetite and weight loss, jaundice, clay-colored stool, dark urine, flu like symptoms, and fatigue.


Dark or orange urine. If your urine is dark or orange particularly if you also have pale stools and yellow skin and eyes your liver might be malfunctioning. Fatty stools; Vomiting; Nausea; Dark urine; Pale stools; Body ache. 1. Yellow Skin (Jaundice). Jaundice is yellowing of the skin and eyes. The presence of pale stools and dark urine suggests an obstructive or post-hepatic cause. Pruritus may be a symptom of raised bile acids. Is the dark urine caused by urobilin, or is it caused by hemosiderin, or does it depend on the type of pathology? In pre-hepatic jaundice, urine color is normal because nothing gets filtered into the urine. For the same reason there is clay colored stool because there is no stercobilonogen. Other signs and symptoms of liver toxicity include: abdominal pain and swelling; chronic itchy skin; dark urine color; pale stool color; joint pain; bloody or tar-colored stool; chronic fatigue; nausea; and loss of appetite. Most stuff I’ve read talked about some form of jaundice but everything said pale stool AND dark urine. My skin and eyes are not yellow either.

Biliary Atresia Symptoms And Diagnosis

White stool is actually very rare and usually means something is seriously wrong inside the body. Dark urine despite plenty of liquids is also a symptom. If the duct draining bile into the intestine is blocked by pancreatic cancer, the stools may lose their brown color and become pale or clay-colored. This ensures no bilirubin is excreted in the urine. At very high concentrations, bilirubin can slowly diffuse into the peripheral tissues where it is toxic. It will result in lots of conjugated bilirubin causing very dark urine and pale stools.
