Most brown normal deposition is a result of old blood cells in a decomposed substance known as bilirubin and released by the liver through the bile production into the intestines. The National Institutes of Health say that the pale or light colored stools may be indicative of a large number of diseases or disorders, some of which can also cause fatigue.
Because the liver is responsible for collecting and releasing bilirubin via the bile into the small intestine, liver disorders such as hepatitis and cirrhosis can cause liver cease operation. If the liver can not produce bile bilirubin and remove blood, stool may become pale or clay-colored. Since bilirubin is not being removed from the blood, increased levels of bilirubin in the blood can contribute to fatigue, particularly if an infection such as hepatitis engages.
Bile duct obstruction
For bile containing bilirubin is released from the liver, the first is stored in the gallbladder, where it is then released through pipes known as bile ducts in the intestines. If these channels are blocked, bile can not travel and feces can become lighter in color. The obstruction of the bile ducts may be caused by trauma, or cysts inflammation of said channels, resulting in a seal. The obstruction of the bile ducts can also occur due to tumors in the pancreas or other tumors in the biliary system. Since bilirubin levels in blood rise, some patients may experience fatigue along with abdominal pain and possibly fever.
Gallstones are a common occurrence among adults. Gallstones develop from bile constituents and may be made of hardened cholesterol or bilirubin. It is more likely to develop gallstones women, particularly if they have lost a lot of weight. Gallstones can vary in size from microscopic to the size of a golf ball. When gallstones become large, they can block the bile ducts releasing bile bilirubin filled into the intestines, causing feces become pale. Other symptoms of gallstones or disease in the gallbladder may include bloating and abdominal pain, which may spread to the back, with fever, fatigue and jaundice.
Some cancers can cause depositions of clear or pale with fatigue. Pancreatic cancer may cause the deposition becomes a light yellow color due to lack of digestive enzymes come from the pancreas. This can also cause fatigue, since the food is not fully digested and nutrients can not be absorbed, resulting in a possible malnutrition. In some cases, pancreatic cancer can also block the bile duct enters the gut area near the pancreatic duct. Bile tumors and other cancers that block location bile duct result in the formation of deposits or clayey pale color. As with all cancers, fatigue is a common effect, particularly if bilirubin levels are high.
Some medications can cause feces become light colored. Medications used in the treatment of infectious diseases, such as isoniazid, used to treat tuberculosis, may induce poor known as cholestatic jaundice, where bilirubin levels are high and can lead to fatigue. Drugs indicated to intestinal complaints such as diarrhea, including bismuth subsalicylate and kaolin, can cause pale stools since they are whitish. This is particularly true when ingested in large doses. The presence of diarrhea can also result in fatigue. Swallowing barium sulfate or receive a barium enema for gastrointestinal X-ray examination will also result in white or pale stools, but fatigue is not a likely outcome of barium swallow.
