This lesson will discuss how age, fiber, and muscle weakness plays a role in a condition called diverticulitis. We'll also cover what diagnostic tests can be run and which treatment options may be employed.
10. Icterus: The Major Causes of Jaundice
This lesson will discuss the major causes of icterus, also known as jaundice. We'll define conjugated and unconjugated bilirubin, when each one may increase, how urine and stool samples may be important, and a whole lot more!
11. The Major Causes of Liver Disease
This lesson will quickly go over what the liver is for and how it may be damaged. Then we'll focus in on how liver damage can be looked for through a physical exam or by way of blood tests.
12. Viral Hepatitis: Causes, Signs and Treatments
This lesson will discuss the different types of viruses that cause viral hepatitis as well as their different characteristics. We will also talk about what kind of harm these viruses bring and how a person can be treated.
13. Cirrhosis: Definition, Causes & Treatments
This lesson will discuss cirrhosis, why it may occur, what it looks like, and how it may be treated. Additionally, you'll learn about fibrosis, hypertension, and what signs to look for on diagnostic tests.
14. Gallbladder Disease: Major Causes, Consequences, and Treatments
This lesson will explore common diseases and conditions associated with the gallbladder, including cholecystitis, cholangitis, and cholelithiasis. This lesson will also cover the major types of gallstones and why they may form.
15. Acute & Chronic Pancreatitis: Causes, Signs & Treatments
This lesson will discuss pancreatitis. We'll go over what a normal pancreas is supposed to do and what goes on during pancreatitis. We'll briefly touch upon its diagnosis and treatment as well.
16. Colorectal Cancer: Risk Factors and Treatment
This lesson will discuss colorectal cancer, adenocarcinoma, and adenomas. We will talk about the early warning signs that someone may develop colorectal cancer as well as diagnostic and treatment strategies.
17. Diagnosis of Abdominal Pain: The Four Quadrants
This lesson will discuss the major points of the four-quadrant approach to diagnosing abdominal pain. While every possible permutation of pain in the abdomen won't be covered, you will come out with a good understanding as to what a problem may be.
