Nonalcoholic fatty liver disease (NAFLD)

• Nonalcoholic fatty liver disease (NAFLD) is a
  condition in which the liver stores excess fat
  but is not secondary to alcohol, a virus, drugs,
  metabolic disorders, syndromes and other factors
  that may affect the livers ability to metabolize
  or export fat.The disease process is usually
  associated with obesity, abnormal lipid levels
  (high cholesterol), diabetes, and
  prediabetes.Severity of Nonalcoholic fatty
  liver disease (NAFLD) can range from fat storage
  in the liver, fat and inflammation in the liver,
  fat and inflammation with a lot of scar tissue in
  the liver (cirrhosis due to NASH).

Causes of Nonalcoholic fatty liver disease
(NAFLD)

• Nonalcoholic fatty liver disease (NAFLD) can be
  understood as excess energy storage in the form
  of fat within the liver. When the balance between
  energy going out is less than energy coming in
  (food), the liver may store excess energy in the
  form of fat.

Diagnosis of Nonalcoholic fatty liver disease

• The diagnosis of Nonalcoholic fatty liver
  disease (NAFLD) requires the presence of fat in
  the liver as seen by imaging studies or histology
  and the exclusion of other causes of fat
  accumulation.Many things can disturb the
  livers metabolic activity and it is vital to
  remove those things as the treatment relies on
  the underlying cause of the problem.Currently
  the only way to distinguish between non-NASH
  NAFLD and NASH is a liver biopsy, however several
  risk calculators and biomarkers have been devised
  to help determine whether a biopsy is needed.

Signs Symptoms of Nonalcoholic fatty liver
disease

• Nonalcoholic fatty liver disease (NAFLD) without
  cirrhosis is regarded as a clinically silent
  disease (does not have symptoms). Some patients
  report some general abdominal symptoms that may
  or may not be related to liver changes.

Treatments of Nonalcoholic fatty liver disease

• The mainstay of treatment for Nonalcoholic fatty
  liver disease (NAFLD) and Non-alcoholic
  Steatohepatitis (NASH) are lifestyle changes
  weight loss, exercise and following a healthy
  diet. These treatments not only target the liver,
  but reduce overall cardiovascular risk, since
  cardiovascular complications are strongly
  associated with Nonalcoholic fatty liver disease
  (NAFLD).In people who have biopsy evidence of
  Non-alcoholic Steatohepatitis (NASH), current
  recommendations include vitamin E. This is not a
  general recommendation that should be started
  without consulting a physician since risks can be
  associated with it.Many other treatments for
  Non-alcoholic Steatohepatitis (NASH) are being
  developed and may be available in the near
  future.

Treatments of Nonalcoholic fatty liver disease
Continue

• Although bariatric surgery can improve
  Nonalcoholic fatty liver disease (NAFLD) and
  Non-alcoholic Steatohepatitis (NASH), it is not
  recommended for those diagnoses alone at this
  time. Patients undergoing bariatric surgery
  frequently do not know they have liver
  disease.If a person has other indications for
  bariatric surgery and evidence of liver disease,
  then bariatric surgery may be performed but
  should be done with the consultation of a liver
  specialist.
