Fatty liver is not contagious.
Under normal circumstances, the fat content in liver cells is generally below 5%. If it exceeds 5%, it is called fatty liver, which can be definitively diagnosed through an abdominal ultrasound. Fatty liver itself is not contagious; it simply reflects an increase in fat content within the liver cells compared to the normal level.
The primary cause of fatty liver is due to excessive calorie intake, which is not metabolized and consumed, leading to excess fat being stored in the liver cells, thus causing fatty liver. Patients with fatty liver should adhere to a light diet, avoid overly greasy and high-fat foods, and exercise more.
