Total annual layer (summer + winter) thickness for 36 varves is plotted on the graph to the right. A data file and the lines posted on the image were all created by a computer program designed to sequentially measure varve sequences.
Blockage of the bile ducts may cause symptoms such as abdominal pain, nausea and vomiting. If the bile duct remains blocked bile is unable to drain properly, jaundice (yellow discoloration of the eyes and skin) can develop and an infection known as cholangitis may also occur.ccasionally the gallstones can also block the flow of digestive enzymes from the pancreas because both the bile ducts and pancreas ducts drain through the same small opening (called the Ampulla of Vater) which is held tight by a small circular muscle (called the Sphincter of Oddi).
Gallstones are the product of bile becoming overloaded with cholesterol, bile salts, or bilirubin. Basically, a diet high in saturated fat and low in fiber is at the root of the problem. In turn, gallstones clog your liver and gallbladder, and prevent the free flow of bile. Other factors that increase the risk of gallstones include food allergies, obesity, insulin resistance, type 2 diabetes, and high levels of blood triglycerides.
