Fatty liver disease FLD , also known as hepatic steatosis , is a condition where excess fat builds up in the liver.

Changes in diagnosis and fibrosis from first biopsy to last showing numbers of patients with changes of diagnosis A or fibrosis stage B. Green boxes indicate improved diagnosis or regression of fibrosis; red boxes indicate worsening diagnosis or progression of fibrosis.

Non-alcoholic Fatty Liver Disease

Back to Health A to Z. It's usually seen in people who are overweight or obese. A healthy liver should contain little or no fat. If detected and managed at an early stage, it's possible to stop NAFLD getting worse and reduce the amount of fat in your liver. Get advice about coronavirus and liver disease from the British Liver Trust. You probably will not know you have it unless it's diagnosed during tests carried out for another reason.

Your liver is the largest organ inside your body. It helps your body digest food, store energy, and remove poisons. Fatty liver disease is a condition in which fat builds up in your liver. There are two main types:. NAFLD is a type of fatty liver disease that is not related to heavy alcohol use.

Non-alcoholic fatty liver disease NAFLD describes a range of conditions caused by a build-up of fat within liver cells. It is very common and in many cases is linked to being obese or overweight. In some people, the build-up of fat in the liver can lead to serious liver disease. However, all people with NAFLD have an increased risk of developing cardiovascular problems such as heart attacks and stroke. If you are obese or overweight, a main treatment advised for NAFLD is usually gradual weight loss and regular exercise.

Fatty liver disease

According to the World Health Organization, the continuing surge in obesity pandemic creates a substantial increase in incidences of metabolic disorders, such as non-alcoholic fatty liver disease NAFLD , type 2 diabetes mellitus, and cardiovascular disease. In mammals, miRNAs function as critical post-transcriptional negative regulators involved not only in many biological processes but also in the development of many diseases such as NAFLD and comorbidities. More recently, it has been described that cells can secrete miRNAs in extracellular vesicles, transported by body fluids, and uptaken by other tissues regulating gene expression. Therefore, this could be a mechanism of signaling involved not only in physiological pathways but also in the development of diseases. The association of some miRNA expression profiles with certain disorders has made them very interesting molecules for diagnosis, prognosis, and disease management. The finding of specific miRNA signatures to diagnose NAFLD and related diseases could anticipate the risk of development of related complications and, actually, it is the driving force of present health strategies worldwide.

Non-alcoholic fatty liver disease NAFLD , also known as metabolic dysfunction associated fatty liver disease MAFLD , is excessive fat build-up in the liver without another clear cause such as alcohol use. An abnormal accumulation of fat in the liver in the absence of secondary causes of fatty liver, such as significant alcohol use , viral hepatitis , or medications that can induce fatty liver characterizes non-alcoholic fatty liver disease NAFLD. These diseases begin with fatty accumulation in the liver hepatic steatosis. A liver can remain fatty without disturbing liver function NAFL , but by various mechanisms and possible insults to the liver, it may also progress into non-alcoholic steatohepatitis NASH , a state in which steatosis is combined with inflammation and sometimes fibrosis steatohepatitis. NASH can then lead to complications such as cirrhosis and hepatocellular carcinoma. Mild yellow discoloration of the skin may occur, although this is rare.

Cirrhosis is the common end stage of a number of chronic liver conditions and a significant cause of morbidity and mortality. With the growing epidemic of obesity and metabolic syndrome, nonalcoholic fatty liver disease NAFLD has become the most common cause of chronic liver disease worldwide and will become one of the leading causes of cirrhosis. Thus, this article reviews recent studies on the epidemiology, risk factors, clinical presentation, diagnosis, management, and prognosis of NAFLD cirrhosis. Cirrhosis is the end stage of a wide number of chronic liver conditions that share common features of necroinflammation, fibrosis, and regenerative nodules, which modify the normal liver structure to reduce its functional mass and alter the vascular architecture [ 1 ]. Cirrhosis has become a major public health problem and a significant cause of morbidity and mortality [ 2 ].

Fatty liver disease: NASH and related disorders

In this review, we discuss the global burden of NAFLD, together with future perspectives on how this epidemic could be restrained. We aim to present the beneficial effects of life-style modifications that should be advised to both non-obese and obese NAFLD patients.

Ангел заговорил: - Дэвид, я люблю. Внезапно он все понял. Сьюзан на экране тянулась к нему, плача и смеясь, захлестнутая волной эмоций. Вот она вытерла слезы. - Дэвид… я подумала… Оперативный агент Смит усадил Беккера на сиденье перед монитором.

 - Когда мистер Беккер найдет ключ, он будет вознагражден сполна. ГЛАВА 22 Дэвид Беккер быстро подошел к койке и посмотрел на спящего старика. Правое запястье в гипсе. На вид за шестьдесят, может быть, около семидесяти.

 Я… понимаю, - тихо сказала она, все еще находясь под впечатлением его блистательного замысла.
