What Does Diagnosis Look Like
Hepatic steatosis can often be diagnosed by imaging techniques, such as ultrasound, computed tomography scan, or magnetic resonance imaging . All types of medical imaging can reveal diffuse fat content in the liver. This finding may also be described as lower liver attenuation, which means that healthy tissue is interrupted by fatty deposits. Imaging tests are performed by radiology specialists and interpreted by radiologists.
Ultrasound imaging is a type of sonography that is useful for detecting fat within the liver. Ultrasound technology utilizes sound waves to detect variations in structures and composition within body tissues. A higher measure of echogenicity will also accompany fat deposits in the liver parenchyma, which is the part of the liver responsible for carrying out the organs processes. Higher echogenicity means that sound waves more readily bounce off fat tissue and echo back to their source. An MRI might reveal a chemical shift that signifies the presence of fat within the liver.
Another type of imaging is called elastography. Elastography can reveal if soft tissue has hardened, indicating damage. For example, normally functioning liver tissue is soft in texture. Scarred or damaged liver becomes harder in texture.
One of the most definitive ways to detect and diagnose fatty liver disease is through a liver biopsy. A liver biopsy requires taking a tiny sample of your liver and analyzing it for the presence of fat cells, lesions, and other abnormalities.
Valproate Induced Hepatic Steatosis By Enhanced Fatty Acid Uptake And Triglyceride Synthesis
VPA induced hepatic steatosis and modulated genes associated with lipid metabolism.
-
CD36-mediated fatty acid uptake contributed to VPA-induced lipid accumulation.
-
VPA increased the hepatic level of DGAT2 through inhibiting MEK-ERK pathway and enhanced triglyceride synthesis.
-
SREBP-1c-mediated fatty acid synthesis was not involved in VPA-induced hepatic steatosis.
Herbal Medicine Ameliorates The Hepatic Inflammation
Hepatic inflammation promotes lipid deposition and redistribution from adipose to liver and drives liver inflammatory injury. Hepatic inflammation triggers the development of NAFLD from hepatic steatosis to steatohepatitis and fibrosis . Amelioration of heaptic inflammation is vital for NAFLD therapy. It has been indicated that herbal medicine has exerted the protective effects against the progression from hepatic steatosis to steatohepatitis and the underlying mechanism have been proved to be involved in inhibiting the inflammatory signaling pathway as shown in Figure 2, thereby regulating dyslipidemia and improving liver function in NAFLD. Many herbal medicine possessed anti-inflammatory properties for slowing down the NAFLD progression, such as Sinai san dection , Hugan Qingzhi tablet , betulinic acid , Alisma orientalis , gastrodin , the peel extract of Citrus aurantium L. and swertiamarin , and all of these medicine reduces the expression levels of hepatic inflammatory cytokines . Baicalin and aqueous extract of Salvia miltiorrhiza Bunge show the anti-inflammatory action, further improve liver fibrosis by inhibition of α-SMA, Col1A1, and TGF-β1 production.

Role Of Fatty Acid Oxidation In Hepatic Steatosis
Mitochondrial fatty acid oxidation. Short- and medium-chain fatty acids traverse the plasma membrane passively while long-chain fatty acids require membrane transporters . LCFAs are acylated in the cytosol and then enter the mitochondria, helped by the carnitine acyl-transferases CPT1 and CPT2. The -oxidation of acyl-coenzyme A takes place in the mitochondria and consists of 4 reactions, with the last 3 catalyzed by the mitochondrial trifunctional protein. -Oxidation spiral leads to the formation of acetyl-CoA, nicotinamide adenine dinucleotide , and flavin adenine dinucleotide from each oxidation cycle. NADH and FADH2 are used by the mitochondrial respiratory chain to generate adenosine triphosphate.
Studies from our group at the University of Missouri document a role for mitochondrial dysfunction in the development of steatosis. Mice heterozygous for MTP that were fed a low-fat chow diet developed insulin resistance and hepatic steatosis in parallel by 9 months of age. This primary defect in mitochondrial -oxidation also causes hepatic insulin resistance, which is selective to impairments in hepatic glycogen metabolism and independent from factors that are known to cause hepatic insulin resistance, such as diacylglyceride and ceramide accumulation in the liver.
Treatment Of Fatty Liver Due To Obesity Or Diabetes
In these cases, the treatment will be aimed at correcting the alterations of the disease that contribute to the development of steatosis. This is the case, for example, of insulin resistance.
The main recommendation for obese people are healthier lifestyle habits. They must maintain a diet balanced and low calorie and perform physical exercise at the least 3 times a week for 30 minutes. In this way, you will achieve the ideal weight gradually.
It will try to avoid the yo-yo effect. The mobilization of fatty acids from adipose tissue to the liver would deprive it of the supply of other necessary nutrients. Consequently, steatosis would worsen and existing tissue lesions would worsen. Therefore, weight loss must be gradual and progressive.
There is also a pharmacological treatment for cases in which the disease continues to worsen.

Lose Weight If Needed
Losing weight can help you reverse fatty liver disease. When you lose fatty tissue, this also means that you are losing fat from your liver.
To facilitate weight loss, aim to create a calorie deficit, meaning you are burning more energy than you consume. Eating healthy foods, controlling portion sizes, and exercising help encourage weight loss.
Make sure that you follow a balanced diet to lose weight, instead of following extreme diet plans. In addition to losing fat, its essential to also maintain muscle mass.
Eat Lots Of Fruits And Vegetables
Fruits and veggies are a critical component of the fatty liver disease diet plan. Both fruits and vegetables are chock-full of anti-inflammatory components like polyphenols, carotenoids, and other antioxidants that can fight liver damage. Reach for foods like broccoli, spinach, apples, blueberries, and raspberries for a liver-friendly diet.

Biological Role Of Insulin
Insulin, after binding its receptor, induces the phosphorylation of receptor substrates in the liver and muscles, and triggers several steps toward the transactivation of glucose transporter-4 .This increases glucose uptake by cells and its storage as glycogen, and inhibits the net production of glucose by the liver, thus blocking glycogenolysis and neoglycogenesis. Moreover, insulin promotes lipid storage by inhibiting lipolysis. When insulin is unable to induce glucose uptake, pancreatic -cells increase insulin production and the hyperinsulinemic state prevents hyperglycemia. Thus, IR depends on insulin secretion and insulin sensitivity.

Type 2 Diabetes And Nash
Type 2 diabetes influences the relationship between NAFLD/NASH and cardiovascular disease. According to research, NAFLD was found in 50% of patients with type 2 diabetes who had an otherwise healthy liver. In addition, NAFLD/NASH-related cardiovascular issues are nearly twice as likely in individuals with type 2 diabetes.
NAFLD/NASH and type 2 diabetes share many of the same risk factors: inactivity, obesity, genetics and environmental factors all add to the occurrence of these diseases. In addition, people with type 2 diabetes are at greater risk of advanced fibrosis, which is a major indicator of NASH.
While serious, the good news is that the same measures to help prevent and treat type 2 diabetes eating healthier, exercise, weight management can improve NAFLD and NASH prognosis.

Endoplasmic Reticulum Stress
ER stress involved the increase of JNK and caspase-12 expression serves a primary role in the procession of NAFLD and pathogenesis to NASH. The pharmacological activation of FXR induced by betulinic acid alleviated the hepatic ER stress-mediated hepatic steatosis . The farnesoid X receptor activation suppresses the expression of ER stress markers and CHOP signaling, thereby reducing hepatocellular ER stress. Betulinic acid could serve as an FXR agonist that effectively attenuates the pathogenesis of HFD and MCD induced NAFLD, and Alisma orientalis could restore the hepatocellular ER homeostasis by stimulating the FXR activation, particularly, Alisol A 24 -acetate accounts for this action .

What Is The Prognosis For Fatty Liver Disease
Research studies are underway to better understand, prevent, and control fatty liver disease. There is ample evidence to suggest that NAFLD, NASH, and alcoholic steatohepatitis are reversible, and progression to cirrhosis is preventable. Numerous research trials are being carried out to understand the factors responsible for fat accumulation in the liver and to explore medications both new and old, that maybe effective in treatment.
Signs And Symptoms Of Nonalcoholic Fatty Liver Disease
Initially, nonalcoholic fatty liver disease may have no symptoms at all. However, as the condition progresses, it may start to exhibit symptoms. Here are a few signs and symptoms of fatty liver disease:
- Fatigue
- Unexplained weight loss
- Pain in the upper right quadrant of your abdomen
If nonalcoholic liver disease progresses to more serious conditions, it can cause more severe symptoms like ascites, jaundice, muscle wasting, and hepatic encephalopathy.
Keep in mind that fatty liver disease rarely occurs in isolation. Metabolic conditions are significant risk factors for developing fatty liver disease. Metabolic syndrome includes conditions like insulin resistance, type 2 diabetes, elevated triglycerides, and high cholesterol. Fatty liver disease is also correlated with obesity and hypertension.
