Prevent Visceral Fatty Liver Disease

Fat men's bellies
An obesity epidemic has made fatty liver disease (steatosis) common, particularly among middle aged Americans, though this health condition may also affect children and young adults.

Fatty Liver Disease Profile

When metabolism slows and physical activity lessens, weight gain is typical as people enter their 50s—particularly around the mid-section. However, our attention focuses on something more profound than a few inches above the waistline.

Traversing nutrition, gastroenterology, endocrinology, and internal medicine, a gastroenterologist is the primary specialist treating fatty liver disease. Doctors diagnose two categories of steatosis: Alcoholic fatty liver disease (AFLD) and nonalcoholic fatty liver disease (NAFLD). Major risk factors include obesity, type 2 diabetes, heredity, and overconsumption of alcohol.

Rapid weight loss and poor eating habits may lead to NAFLD. Malnutrition and micro­nutrient (including protein) deficiencies are common among those with liver diseases. However, some people develop NAFLD even if they do not have any risk factors. NAFLD affects up to 25% of people in the United States. Untreated NAFLD can progress to a more severe form called Non-Alcoholic steatohepatitis (NASH), with the potential for developing cirrhosis and liver cancer.

As the name implies, fatty liver disease is a result of too much visceral fat stored within the liver. (Other organs like your pancreas, stomach and intestines may accumulate visceral fat.) Generally a benign condition, it usually causes no symptoms. When symp­toms do occur, they include fatigue, weight loss, and abdominal pain. You may experience restricted range of motion. Bending forward can feel like your abdomen is full of bubble wrap.

Unlike visceral fat, subcutaneous fat located right beneath the skin can be measured with calipers to determine your body fat levels. Although this type of fat does not present health risks, it does affect your appearance. Subcutaneous fat may not respond to positive changes in exercise and diet, but it can be removed with liposuction.

Performing secondary endocrine functions, the liver synthesizes and secretes at least four important hormones:

  1. Angiotensinogen
  2. Betatrophin
  3. Hepcidin
  4. Thrombopoietin

Too much visceral fat can interfere with how your liver functions and interrupt everyday hormo­nal communica­tions between vital organs. This can lead to insulin resis­tance (the beginning of diabetes), high blood pressure, high cholesterol levels and a higher risk for developing heart diseases. In a minority of patients, fatty liver disease may progress to liver failure (cirrhosis). A cirrhotic liver can resemble overcooked meat, rendering it useless.

How to Prevent Visceral Fatty Liver Disease

Most liver cysts are found incidentally on imaging studies that may be ordered for other reasons. Liver cysts (hepatic cysts), detected in 4–7% of the population can be asymptomatic with just a few, requiring no treatment. When numerous or very large, cysts may cause pain or discomfort in the upper right abdominal region. They can be empty or fluid-filled (hydatid).

Complications and Causes

Patients with hydatid cysts should receive treatment to prevent complications of cyst growth and rupture. Simply removing the fluid from the cyst with a needle is not effective because the cyst fills up again within several days. The preferred treatment is to remove a large portion of the cyst wall.

Consuming soft drinks can increase the prevalence of NAFLD independently of metabolic syndrome. During regular soft drink consumption, fat accumulates in the liver as a primary effect of fructose. This increases lipogenesis.

Diet soft drinks, by the addition of aspartame sweetener and caramel colorant, are rich in advanced glycation end products. These potentially increase insulin resistance and inflam­mation. Fortunately, dangerous visceral fat may be somewhat easy to lose if you have a balanced diet, rest regularly, and exercise for 35 to 60 minutes daily.

When alcohol is the cause and AFLD is discovered early, abstinence can reverse some of the effects. Suppose you have been drinking more than 60 grams (2 ounces) of alcohol per day for a while. In that case, chances are you already have alcoholic fatty liver disease. Hypoechoic and hyperechoic—if numerous, are likely to be metastatic. Anechoic lesions are hepatic cysts (fluid-filled sacs) or cystic lesions.

Nonalcoholic steatohepatitis, a potentially serious form of NAFLD, is marked by liver inflam­mation or swelling which may progress to scarring and irreversible damage. There are no medical treatments yet for NAFLD.

The majority of liver cysts are benign, but all cancers are able to produce malignant cysts. Cystic tumors are abnormal masses that have the potential to become malignant. Benign cystic tumors are called cysta­denomas; their malignant counterparts are called cysta­deno­carcino­mas.

Treatments

Statins are often underused in patients with non-alcoholic fatty liver disease. Many physicians are concerned about the prescription of statins to patients with active liver disease because of its adverse effect. The risks of not taking statins may outweigh the risks of taking the drug. Conversely, the usefulness of statins for the treatment of NAFLD is still a matter of debate.

Eating a healthy diet and exercising regularly may help prevent liver damage from starting or reverse it in the early stages. Try consulting with a nutritionist and joining a gym as favorable options. Fatty liver can be detected with blood tests and confirmed by ultra­sound. October is Liver Disease Awareness Month.
