Fatty liver, also known as hepatic steatosis, typically appears normal in most cases on MRI. However, a minority of cases may show high signals on T1 and T2. In fat-suppressed sequences, the high signals disappear after the fat is suppressed, appearing as low signal shadows. MRI has a specific sequence for examining fatty liver, known as the dual-echo sequence, which includes two sequences: one is the in-phase sequence and the other is called the opposed-phase sequence. The in-phase sequence examines the liver parenchyma, while a characteristic feature in the opposed-phase sequence is the significant decrease in signal in areas of fatty metamorphosis.

Can mild fatty liver heal itself?

Mild fatty liver can potentially be cured. Mild fatty liver refers to a lesser accumulation of fat in the liver. If one can effectively control their diet and enhance physical exercise, healing can be achieved. Fatty liver means that a large number of fat cells are not consumed and accumulate in the liver, causing damage to the liver cells, which we call fatty liver. In people with mild fatty liver, there is less fat accumulated in the liver. If one can persist in effectively controlling their diet while also appropriately strengthening physical exercise, self-healing can occur. People with fatty liver also need to regularly monitor liver function for any changes. If there is liver damage, it may be necessary to receive appropriate treatment with liver-protecting drugs. If liver function is normal, simply exercising reasonably and controlling diet can alleviate symptoms and signs.

The best method to eliminate fatty liver.

For the treatment of fatty liver, the general treatment first needs to identify the cause. For example, patients who drink alcohol excessively need to quit drinking; patients who are obese due to excessive nutrition should control their diet to help return their weight to normal; patients with concurrent diabetes should actively and effectively control their blood sugar; patients with malnutrition-related fatty liver should appropriately increase their nutrition intake, especially of proteins and vitamins. Secondly, adjust the dietary structure by appropriately increasing the intake of proteins and fiber while aiming for a low-sugar, low-fat diet. Minimize consumption of animal fats and eat more vegetables, fruits, foods rich in fiber, and high-protein foods, such as lean meats, fish, and soy products. Most importantly, increase physical exercise to promote the consumption of fats within the body. Aerobic exercises, such as jogging, cycling, swimming, and jumping rope, should be the exercises of choice.

Can fatty liver be cured?

Fatty liver is relatively common in clinical practice, often seen in obese patients or those who consume alcohol excessively. Fatty liver is also categorized as mild, moderate, or severe in clinical settings. Generally, mild fatty liver does not accompany liver function abnormalities. For such patients, the main approach involves appropriate weight loss, exercise, and dietary control. If there are indeed complications like cirrhosis or more severe liver disease, including abnormal liver functions, systematic diagnosis and treatment are recommended. Besides completing abdominal ultrasound and liver function tests, it is also suggested to conduct quantitative hepatitis B virus tests to eliminate the possibility of hepatitis B virus-induced steatosis. Generally, fatty liver can be treated successfully; however, if it is complicated by cirrhosis, the main principle of treatment is to prevent complications, and complete cure may not be possible. Therefore, regarding fatty liver, there is no need for excessive worry, but standard treatment should be followed. Particularly if the fatty liver is complicated by cirrhosis, active diagnosis and treatment are generally recommended.

Does fatty liver disease transmit?

Fatty liver is relatively common in clinical practice. It is not an infectious disease and is not contagious. Fatty liver is generally considered to be caused by various reasons leading to fat deposition in the liver. Usually, there are no specific symptoms. Some patients may experience pain, dull pain, or discomfort in the upper right abdomen, along with nausea, etc. Typically, patients discover they have fatty liver during a physical examination or incidental liver function tests and abdominal ultrasound that indicate changes due to fatty liver. The general principle of treatment is symptomatic management. If liver function is abnormal, hepatoprotective treatment can be considered. Of course, if liver function is normal and it's purely fatty liver, the main approach is adjusting dietary and lifestyle habits. It is advised that patients consume high-quality proteins and reduce intake of greasy, fatty, low-fat, and low-sugar foods. Maintaining a good mental state, appropriately reducing weight, and exercising can cure mild fatty liver. If there is severe fatty liver, it is recommended that patients visit a local hospital for treatment.

How long does it take to recover from fatty liver with exercise?

Fatty liver is a reversible disease that can gradually improve with proactive treatment, dietary adjustments, and appropriate exercise, although the duration of exercise varies from person to person. For mild fatty liver, the treatment period is short. In cases of severe fatty liver, exercise therapy must be complemented with medications, which extends the time required. Currently, there are no specific drugs that completely cure fatty liver. The main treatments involve protecting liver cells, reducing lipid levels, and using antioxidants. It is important to adjust the diet promptly, reduce the intake of greasy food, especially animal fats, and increase outdoor activities such as jogging and playing badminton. Maintaining a positive mindset also helps in recovery. (The use of medications should be under the guidance of a doctor.)
