Lean non-alcoholic fatty liver disease (NAFLD) affects non-obese individuals and shares metabolic issues with obese NAFLD patients. Lifestyle changes are recommended for managing this growing condition in adults and children.
Area of Science:
- Hepatology
- Metabolic Disorders
- Internal Medicine
Background:
- Non-alcoholic fatty liver disease (NAFLD) is a growing concern due to its increasing prevalence and links to diabetes, cardiovascular disease, and metabolic syndrome.
- NAFLD is increasingly recognized in non-obese individuals, a subset termed 'lean NAFLD' or 'non-obese NAFLD'.
- The prevalence of lean NAFLD is rising in both adult and pediatric populations.
Purpose of the Study:
- To summarize the clinical manifestations of lean NAFLD.
- To review the pathophysiology of lean NAFLD.
- To outline the management strategies for lean NAFLD in pediatric and adult populations.
Main Methods:
- A formal literature review was conducted.
- Independent analysis by two reviewers.
- Searches included PubMed and EMBASE databases up to April 2018.
Main Results:
- Lean NAFLD patients exhibit metabolic features like insulin resistance and dyslipidemia, similar to obese NAFLD patients.
- Potential contributing factors to lean NAFLD pathogenesis include genetic predisposition, diet, and environmental influences.
- Genetic and metabolic conditions warrant consideration in lean NAFLD.
Conclusions:
- Currently, no formal treatment recommendations exist for lean NAFLD in adults or children.
- Lifestyle modifications focusing on improved overall fitness are likely beneficial for managing lean NAFLD.
- Further research into the specific mechanisms and treatments for lean NAFLD is warranted.

Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

The process of oxidation in a chemical reaction is observed in any of the three forms:

Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.

Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...

Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...
