Obesity And Nafld Essay

2393 words - 10 pages

This disease was uncommon in the old days because it was unusual to accumulate enough fat to hurt livers. However, many people in the United States are now suffering from NAFLD and NASH. Before 1998, there was no case of NASH heard. In contrast, a statistics from a website called "Partners In Liver Wellness" provides an alarming information. The site says, “As a consequence of the on-going obesity epidemic in the U.S., fatty liver is a very common disorder with an estimated two thirds of obese adults and half of obese children having fat accumulation in the liver”8. It also mentions that up to 20% of those who are obese may suffer from NASH. This is a frightening number if this happened at, for example, West Anchorage High School. In high schools in the United States, around 20 percent of the students are obese. If half of those students are going to suffer from NAFLD, one in ten students are going to have it. If you are in a class with fifty students, one of them are going to die because of NASH. In the whole entire school at West High, around 40 students will be affected by this disease. The text next talks specifically about what kind of food we should eat in order to prevent this illness. It says, ”[Omega-6] supports skin health, lower cholesterol, and help make our blood ‘sticky’”8. Omega-6 fatty acid is in poultry, eggs, avocado, hemp oil, soybean oil, and cottonseed oil. Omega-3s are another good fat for human. According to the text, it reduces the risk of getting a heart disease and a stroke while helping to reduce symptoms of hypertension. Many kinds of fish contains omega-3 fatty acid. Scientific researches say human should take omega-3 and omega-6 at the ratio of 1:1 to 1:4. In contrast, in a typical American meal, Americans take those oil in a ration of 1:15 to 1:30. This shows that human should think our intake of fatty acid in their everyday life.
NASH is life threatening not only because the condition it will lead to, but also because it does not have noticeable symptoms before the patient is in danger of life. NASH occurs in people who drink little or no alcohol and affects 2 to 5 percent of Americans, especially people who are middle-aged and overweight or obese. It may take many years for NASH to become severe enough to cause symptoms. National Digestive Diseases Information Clearinghouse (NDDIC) indeed says, “NASH is usually a silent disease with few or no symptoms”3. The article also says that as the symptoms get worse, patients might experience weight loss and weakness. Once a person feels fatigue, that means that the disease is advanced or cirrhosis is present. As the liver gets weakened into a condition of cirrhosis, liver enzymes increase because whenever a liver cell breaks down, it release its enzymes from itself. Also, as the liver a patient gets scarred, it starts to swell up to 3 times of its size. Because of these, NASH may be suspected if blood tests show high levels of liver enzymes or if scans show fatty liver....
