Liver function tests show only elevated total bile acids, with all other results normal.

Generally, when a liver function test shows only elevated total bile acids with all other indicators normal, it means the level of total bile acids in the patient's blood exceeds the normal range while results of other tests remain within normal limits. This condition may be caused by factors such as liver cell damage, liver disease, or fatty liver. Specific analyses are as follows:

1. Liver cell damage

Damage to liver cells may lead to increased permeability of proteins and bile acids within the liver, resulting in elevated concentrations of total bile acids. Patients with isolated elevation of total bile acids and otherwise normal liver function tests can often improve through various treatment approaches.

2. Hepatitis

In patients with hepatitis, there may be impaired activity of enzymes involved in plant-derived fatty acid oxidation and bile acid metabolism, leading to increased levels of total bile acids.

3. Fatty liver

Fatty liver refers to the accumulation of excessive fat in liver cells. These patients may develop chronic hepatitis, which can also impair bile secretion in the liver, thereby increasing total bile acid levels.

In addition to the above causes, elevated total bile acids may also result from hyperthyroidism, liver cirrhosis, or bile duct stones. It is recommended to seek timely medical evaluation to avoid delays in diagnosis and treatment. In daily life, maintain a light diet and avoid spicy or irritating foods to prevent worsening of symptoms.
