Free vector stages of liver damage infographic

Hepatic steatosis, another name for fatty liver disease, is a disorder where fat builds up in the liver cells. There are two primary kinds of this condition: non-alcoholic fatty liver disease (NAFLD) and alcoholic fatty liver disease (AFLD).

Fatty Liver Disease with Alcoholism (AFLD):

Cause: The main cause of AFLD is excessive alcohol consumption. Alcohol consumption by the liver can cause fat to build up in the liver’s cells.

Symptoms: AFLD may not show any symptoms at all in its early stages. The symptoms of the condition might worsen with time and include jaundice, exhaustion, and stomach pain.

Complications: If alcohol intake persists, AFLD may develop into more serious liver diseases such cirrhosis and alcoholic hepatitis.

Fatty Liver Disease Without Alcohol (NAFLD):

Cause: Drinking alcohol has no bearing on NAFLD. It is frequently linked to metabolic disorders such type 2 diabetes, insulin resistance, and obesity. Although the precise reason is unknown, sedentary lifestyle, food, and genetics are thought to play a role.
Categories:
Non-Alcoholic Fatty Liver (NAFL): Defined by fat buildup in the liver without accompanying inflammation.
Non-Alcoholic Steatohepatitis (NASH): Causes inflammation and damages liver cells, with more severe consequences possible.

what causes fatty liver disease

There are many different causes of fatty liver disease, but two primary forms can be distinguished: alcoholic fatty liver disease (AFLD) and non-alcoholic fatty liver disease (NAFLD).

An outline of each type’s main reasons is provided below:

Fatty Liver Disease with Alcoholism (AFLD):

Overconsumption of Alcohol: Prolonged and excessive alcohol use is the main cause of AFLD. Alcohol consumption by the liver can cause fat to build up in the liver’s cells. The threshold for alcohol consumption that results in AFLD differs from person to person.

Fatty Liver Disease Without Alcohol (NAFLD):

Obesity: Being overweight, particularly in the abdomen, increases the chance of developing NAFLD. The distribution of body fat is intimately related to the buildup of fat in the liver.

Insulin Resistance and Type 2 Diabetes: There is a link between a higher risk of non-alcoholic fatty liver disease (NAFLD) and insulin resistance, a condition in which the body’s cells do not respond to insulin as intended.

High Blood Lipids: Fatty liver disease can arise as a result of high triglyceride and other blood lipid levels.

Metabolic Syndrome: Abnormal lipid levels, obesity, high blood pressure, insulin resistance, and metabolic syndrome are a group of disorders that are frequently observed in association with non-alcoholic fatty liver disease (NAFLD).

Genetics: A family history of NAFLD can raise a person’s risk of getting the disorder, and some people may be genetically predisposed to it.

Fatty liver disease may occasionally develop as a result of rapid weight reduction or starvation.
It is noteworthy that the precise mechanisms by which these factors lead to the onset of fatty liver disease remain incompletely known, and that a combination of factors may heighten an individual’s vulnerability.

There is also a spectrum of non-alcoholic steatolivepatitis (NAFLD), which includes inflammation and damage to the liver cells, and simple fatty liver (steatosis). Liver cancer and cirrhosis are two additional serious disorders that can develop from NASH.

fatty liver disease symptoms

Not all cases of fatty liver disease will exhibit symptoms, particularly in the early stages. However, a variety of symptoms could appear in people as the illness worsens. It’s crucial to remember that symptoms might differ and that some people may not have any symptoms at all, even when they have a considerable buildup of liver fat.

The following are typical signs of fatty liver disease:

weariness: Feelings of weakness and chronic weariness may be early indicators of fatty liver disease.

Abdominal Discomfort: The liver is positioned in the upper right side of the abdomen, which is where some people with fatty liver disease may feel pain or discomfort.

Unexpected Loss of Weight: The metabolic alterations linked to liver failure may occasionally lead to inadvertent weight loss.

Enlarged Liver: The liver may get larger as a result of fat accumulation. Occasionally, this might be felt as a lump or fullness in the upper right abdomen.

Jaundice: As the illness worsens or develops over time, jaundice may happen. Jaundice is a condition marked by yellowing of the skin and eyes and is caused by a malfunctioning liver.

edema (Edema): A consequence of advanced fatty liver disease or cirrhosis can be fluid retention and edema, especially in the legs and abdomen.

It should be emphasized that there can be a large range in the severity of symptoms, and that some people may not experience any symptoms for an extended period of time. Often, fatty liver disease is unintentionally found during normal medical examinations or imaging scans carried out for other purposes.

fatty liver disease diagnosis

A patient’s medical history, physical examination, blood tests, imaging scans, and occasionally a liver biopsy are all used to diagnose fatty liver disease.

An outline of popular diagnostic techniques is provided below:

Medical Background and Physical Assessment:

Your medical history will be questioned by your healthcare provider, along with any risk factors like alcohol use, obesity, diabetes, and liver disease in the family.
To look for indications of liver enlargement, pain, or other abnormalities in the abdomen, a physical examination may be conducted.

Blood Examinations:

Tests for Liver Function: Hepatic function markers, including ALT and AST levels, are measured in blood tests. Increased enzyme levels could be a sign of damage or inflammation to the liver.
Lipid Profile: To determine whether elevated triglycerides or cholesterol, which are linked to fatty liver disease, are present, blood lipid levels are measured.

Imaging Research:

Ultrasonography: This non-invasive imaging method is frequently used to identify liver fat. Assessing the size and texture of the liver can also be aided by ultrasound.

Magnetic Resonance Imaging (MRI) and Computed Tomography (CT): These imaging modalities can help determine the extent of fat deposition and offer more comprehensive images of the liver.

Transient Elastography or FibroScan: This non-invasive test assesses liver stiffness, which serves as a marker for liver fibrosis. It is being utilized more frequently in place of liver biopsies in some situations.

Liver Biopsy: A liver biopsy may be advised in certain cases, particularly if the diagnosis is ambiguous or if the extent of liver damage needs to be determined. Under a microscope, a tiny sample of liver tissue is taken and analyzed.

Discard Any Further Circumstances: It’s critical to rule out other disorders and diseases of the liver that could cause liver damage or have symptoms that are similar.

By combining these diagnostic instruments, medical practitioners can ascertain whether fatty liver disease is present, how severe it is, and whether liver fibrosis or inflammation is present as well. Appropriate management techniques, which frequently entail lifestyle adjustments like food adjustments, weight loss, and increased physical activity, are also guided by the diagnosis.

fatty liver disease treatment

Since there isn’t a single drug that is universally advised for fatty liver disease, lifestyle changes are the mainstay of treatment. Controlling risk factors, lowering liver fat, and stopping the disease’s progression are the objectives of treatment.

The following are essential elements of treating fatty liver disease:

Loss of Weight:

It is important for people with fatty liver disease, especially those who are overweight or obese, to reach and maintain a healthy weight. Liver fat can be considerably reduced with even a small weight loss of 5–10% of body weight.

a nutritious diet

It’s crucial to choose a healthy, balanced diet.

This comprises:

Cutting Back on Sugar and Refined Carbs:  Reducing the amount of sugar-filled foods and drinks will assist enhance insulin sensitivity and lessen the buildup of fat in the liver.

Increasing Fiber Intake: Eating a diet high in fruits, vegetables, and whole grains will help manage weight and promote general health.

Cutting Down on Trans and Saturated Fats: Limiting the consumption of trans and saturated fats can aid in blood lipid regulation.

Frequent Workout: Regular exercise can lower liver fat, improve insulin sensitivity, and help people control their weight. Strength training and aerobic exercise have advantages.

Handling of Supporting Conditions: If diabetes, high blood pressure, or high cholesterol are linked to fatty liver disease, controlling these disorders is crucial to halting more liver damage.

Preventing Overindulgence in Alcohol: Eliminating or minimizing alcohol intake is essential for people with alcoholic fatty liver disease in order to stop more liver damage.

Drugs: While there isn’t a single drug that is licensed specifically to treat fatty liver disease, some may be recommended to address related problems like high cholesterol or diabetes.

Frequent Observation:  It is crucial to schedule routine follow-up appointments with medical professionals in order to track development, evaluate liver function, and modify the treatment plan as necessary.

fatty liver disease self-care

In order to manage fatty liver disease and stop its progression, self-care is essential. These broad self-care techniques can be helpful, while precise advice may differ depending on a person’s health and the severity of the disease:

Take Up a Healthful Diet:

Limit Sugars and processed Carbohydrates: Cut back on the amount of sugar-filled meals and drinks that you consume, along with processed carbs.

Select Good Fats: Choose for foods high in healthful fats, such avocados, fatty salmon, and olive oil.

Boost Your Fiber Intake: To improve digestion and general health, eat a diet high in fiber from fruits, vegetables, and whole grains.

Control Your Weight: Combine a balanced diet with frequent exercise to reach and maintain a healthy weight. Significant benefits for the liver can result with even a small amount of weight loss.

Take Part in Regular Exercise: Include weight training as well as aerobic exercises like swimming, jogging, or walking in your regimen. Exercise lowers liver fat and increases insulin sensitivity.

Limit Your Alcohol Consumption:  Limiting or quitting alcohol completely is important for those who suffer from alcoholic fatty liver disease.
Maintain Hydration: To maintain general health and aid in the removal of toxins from the body, make sure you are drinking enough water.

Control the underlying conditions

In order to properly treat medical disorders like diabetes, high blood pressure, or high cholesterol, collaborate with your healthcare professional.

Steer clear of fast weight loss or crash diets:

In general, slowing down gradually and maintaining it is better than losing weight quickly, which can cause the liver to release fat that has been stored.

Obtain Enough Sleep: Aim for seven to nine hours of good sleep every night. Sleep disorders may be a factor in liver-damaging metabolic abnormalities.

Decrease Tension: Engage in stress-relieving exercises like yoga, deep breathing, or meditation. Persistent stress has an effect on the liver as well as general health.

Limit Consumption of Processed Foods and Salt: Reduce your intake of processed meals that are high in salt and preservatives because too much salt can make you retain fluid.

Keep an eye on your medications: Before using any over-the-counter drugs or supplements, speak with your doctor because some may interact negatively with liver function.

Attend Check-Ups Frequently: See your doctor on a frequent basis to discuss monitoring and, if needed, treatment plan modifications.

It’s critical to remember that managing fatty liver disease requires specific guidance from a medical expert. These self-care techniques are suggestions; you may need to modify them to fit your requirements and particular health condition. Always seek the advice of your healthcare practitioner to create a detailed management plan for fatty liver disease and to receive tailored instructions.
