The work is to be 5 pages with three to five sources, with in-text citations and a reference page. As well known, exercise increases the body temperature and in turn raises the rate of metabolic reaction, which assists in melting of fats in the body. Nonalcoholic steatohepatitis is one such controversial disease in the field of medicine whose main causes are not clearly known. Nonalcoholic steotohepatitis disease refers to condition that causes inflammation, accumulation of fats and tissues as well as damage of the liver. In the view of Kaplan (2011), nonalcoholic steatohepatitis disease occurs to individuals who consume little or no alcoholic drinks. However, pathologists have placed large correlation of nonalcoholic steatohepatitis disease with diabetes, obesity and resistance of insulin by the body. Causes of Nonalcoholic Steatohepatitis (NASH) Disease In the views of Kaplan (2011), there are no defined causes of nonalcoholic steatohepatitis disease. However, medical research conducted with reference to this disease reveal that the disease has got close links with other certain identifiable diseases. One of the discovered complementary diseases linked with nonalcoholic steatohepatitis is obesity. Kaplan (2011) asserts that more than 70% of patients diagnosed with NASH disease had cases of obesity. Large number of obese people discovered to suffer from NASH had exceeded their maximum body weight by over 10% to 40%. Diabetes is also illustrated as one of the complimentary diseases to NASH. Medical research has additionally indicated that 75% of individuals diagnosed with NASH disease exhibited signs of diabetes mellitus 2. In the views of Kaplan (2011), about 20%-80% of the patients suffering from NASH had signs of hyperlipidemia in their blood. Hyperlipidemia disease is caused by excess lipids in the blood of an individual. This condition leads to blockage of blood vessels resulting to development of coronary disease that reduces amount of blood supply to the heart. This leads to hypertension due to straining of the heart in an attempt to circulate blood to the entire body. Resistance to insulin secretion is another probable complimentary disease associated with NASH. Absence of insulin in the body leads to increase in the sugar levels of the blood. This condition if accumulated leads to the development of diabetes mellitus. Another probable cause of NASH disease is the use of certain drugs and toxins, which causes complications related to the NASH disease (Kaplan, 2011). Drugs that have been noticed to cause NASH in the field of medicine include the amiodarone, which encompasses corderone, and pacerone, steroids that encompass predisone and hydrocortisone, tamoxifen and synthetic estrogens. In addition, Kaplan (2011) confirms that use of chemicals such as pesticides and insecticides poison the cells thereby resulting to the development of the NASH disease. Symptoms of NASH Disease According to Kaplan (2011), NASH disease displays no clear symptoms that may lead to its easy detection. This is because NASH disease only develops through a progressive damage of the liver with increase with its severity. The only conditions that have been used to detect and test for NASH in the bodies of patients have been fatigue, general body illness, and pain in the upper right abdomen.
