Hepatic Steatosis - Symptoms and Treatment

Introduction:

Liver is the largest unique vital organ of the body, which is located in the right upper quadrant of the abdomen and performs various exocrine and endocrine functions of the body. The functions of the liver include storage of energy, aid in digestion, body detoxification, and metabolization of drugs. Injury to the liver can be due to various factors such as viral, autoimmune, lifestyle changes, etc.

Many diseased conditions affect the functionality of the liver. Over intake of calories in the body results in fat deposition in the liver's tissues and causes scarring, resulting in complications.

What Is Hepatic Steatosis?

An increase in the accumulation of fat deposits in the liver is termed hepatic steatosis. Fat infiltration is termed fatty liver infiltration if the range of deposition and weight exceeds 5%. Consumption of too much alcohol can lead to this condition, which can result in fat buildup in the liver. Some individuals who do not drink alcohol can also get this condition. It is a benign condition but is a silent killer.

What Are the Forms of Hepatic Steatosis?

Hepatic steatosis especially occurs in two forms:

1. Alcoholic Liver Disease (ALD): Excess consumption of alcohol leads to this state where alcoholic fatty liver occurs due to the accumulation of fat. Around 5% of people in the U.S are affected by this form of hepatic steatosis.

2. Nonalcoholic Fatty Liver Disease (NAFLD): Non-alcoholic individuals are affected by this condition. This can be further classified into the non-alcoholic fatty liver (NAFL) and non-alcoholic steatohepatitis (NASH). NAFLD occurs in one in three adults and one in 10 children in the US. The exact cause of this condition is still unknown. Many factors are linked to this condition, like obesity and diabetes, which can, in turn, increase the risk of having NAFLD.

What Are the Stages of Hepatic Steatosis?

Hepatic steatosis progress through four stages:

1. Simple Fatty Liver - Excess fat in the liver gets buildup and, most of the time, is harmless.

2. Steatohepatitis - Inflammation is also caused by fat deposition.

3. Fibrosis - Continuous inflammation of the liver can result in scarring, but the liver's functionality does not affect it.

4. Cirrhosis - Scarring of the liver. The end-stage condition impairs the ability of the liver to function properly. It is a severe and irreversible stage.

What Are the Signs and Symptoms of Hepatic Steatosis?

Both alcoholic fatty liver disease and non-alcoholic fatty liver disease cause no major noticeable symptoms. Some symptoms which are exhibited are:

• Fatigue.

• Malaise.

• Nausea and vomiting.

• Pain and discomfort on the right upper side of the abdomen.

• Jaundice.

• Cirrhosis.

• Loss of appetite.

• Weight loss.

• Itchy skin.

• Pale-colored stools.

• Easy bruising and bleeding.

• Dark-colored urine.

• Ascites (fluid accumulation in the abdomen).

• Swelling of legs.

• Spider angioma (abnormal collection of blood vessels under the skin).

• Gynecomastia (increased amount of breast tissue gland in men, along with an imbalance in estrogen and testosterone hormone in men).

• Confusion.

How Is the Diagnosis of Hepatic Steatosis Made?

Fatty liver, as such, does not reveal any symptoms. The health care provider may spot it first.

Elevation in levels of liver enzymes may be the indication that the liver is injured, and to affirm it, other methods of evaluation are done, like:

• CT (computed tomography) scan.

• MRI (magnetic resonance imaging).

• Ultrasound (diagnostic imaging method which uses sound waves to produce images).

• Liver biopsy (investigation method where a small part of liver tissue is removed from the affected part to examine under a microscope).

• Fibroscan: Specialized ultrasound that is used to find the amount of fat deposition and scarring on the liver tissue.

What Is the Treatment Provided for Hepatic Steatosis?

Lifestyle changes can significantly improve liver health. There is no specific medication for hepatic steatosis, but certain steps can be taken to prevent and control the factors that affect this condition.

Management includes:

• Avoiding alcohol consumption.

• Maintaining a controlled weight.

• Medication to control diabetic conditions.

• Medication to control cholesterol and fat in the blood.

• Recommended taking vitamin E supplements.

• Thiazolidinediones.

What Are the Complications of Hepatic Steatosis?

The complications of Hepatic steatosis result in serious conditions like cirrhosis (end-stage scarring of the liver). Due to trauma and injury caused by liver inflammation, scarring spreads throughout and affects liver functionality. Other complications include:

• Ascites (fluid buildup in the abdomen).

• Confusion and drowsiness.

• Liver cancer.

• Swollen vessels in the esophagus can burst off and bleed.

• Liver failure.

What Measures Can Be Followed To Prevent Hepatic Steatosis?

Preventive measures mainly include preventing the conditions leading to ALD (alcoholic liver disease).

• Alcohol consumption in moderation. Limiting the intake of alcohol can avoid many serious conditions of the liver.

• Getting vaccination for hepatitis. Vaccination is a bliss. Getting vaccinated for hepatitis can avoid the seriousness of hepatitis. Thus, saving the liver.

• Protect from hepatitis C - Drinking alcohol is the prime reason for getting cirrhosis in this viral infection.

• Do not mix alcohol with other medications. Check with your health care provider before taking any medications. Over-the-counter medications like Acetaminophen can lead to severe liver damage if combined with alcohol.

What Are the Measures To Prevent Conditions Like NAFLD and NASH?

To prevent conditions leading to NAFLD and NASH, the measures to be taken are:

• Eating a portion of healthy food, plant-based, along with lots of fruits, vegetables, whole grains, and healthy fats.

• Maintaining a healthy weight, losing weight if required, choosing a healthy diet, and exercising regularly.

• Staying active and exercising on most days of the week could help to have a healthy liver.

Conclusion:

Non-alcoholic fatty liver disease is a multisystem disease that affects the liver and a wide range of extrahepatic organs. Hepatic steatosis is independently responsible for increased inflammation and incensed systemic inflammation. Hepatic steatosis is a significant risk factor that can develop hepatocellular carcinoma depending on age, sex, obesity, and fibrosis stages. Hepatic steatosis is a challenging condition after liver resection and liver transplantation. Many reports have studied the complications of steatosis impact after liver resection, resulting in mortality and morbidity.
