Alanine aminotransferase decreased, aspartate aminotransferase increased

Alanine aminotransferase (ALT) is commonly referred to as serum glutamic-pyruvic transaminase (SGPT), and aspartate aminotransferase (AST) is generally known as serum glutamic-oxaloacetic transaminase (SGOT). A decrease in ALT with a simultaneous increase in AST may be caused by unhealthy lifestyle habits, medication use, viral hepatitis, myocarditis, fatty liver disease, or other factors. Patients should promptly seek medical evaluation at a正规 hospital to identify the underlying cause and receive appropriate treatment. Specific analyses are as follows:

1. Unhealthy Lifestyle Habits

Unhealthy behaviors such as a high-fat diet, excessive alcohol consumption, and smoking can negatively affect the liver, leading to the aforementioned abnormalities. In such cases, patients should promptly correct these poor habits, avoid staying up late and excessive drinking, and maintain sufficient sleep. Symptoms typically improve with these lifestyle adjustments.

2. Medication Factors

Long-term use of certain medications—particularly antibiotics, antiepileptic drugs, and anti-tuberculosis agents—can adversely affect liver function, resulting in these changes. Patients should discontinue the suspected medication promptly and consult a physician at a hospital. Additionally, dietary adjustments should be made, avoiding spicy and irritating foods.

3. Viral Hepatitis

Viral hepatitis, especially hepatitis B and hepatitis C, is a common cause of liver damage and inflammation. During these viral infections, damaged liver cells may release enzymes that lead to decreased ALT and elevated AST levels. Some patients may also experience symptoms such as nausea, vomiting, and aversion to oily foods. Under medical guidance, patients may be treated with medications such as entecavir tablets, tenofovir disoproxil fumarate tablets, or compound glycyrrhizin tablets.

4. Myocarditis

Myocarditis is primarily caused by infections or autoimmune factors. Due to inflammatory stimulation, patients may exhibit the aforementioned enzyme changes, accompanied by severe fatigue, palpitations, and chest tightness. Under medical supervision, treatment may include medications such as enalapril maleate tablets, losartan potassium tablets, or furosemide tablets.

5. Fatty Liver Disease

Fatty liver is mainly caused by long-term alcohol consumption, obesity, and related factors. Patients may present with the described enzyme pattern and may also experience fatigue, discomfort in the upper right abdomen, and sleep disturbances. It is recommended that patients receive treatment under medical guidance using medications such as atorvastatin calcium tablets, rosuvastatin calcium tablets, or ursodeoxycholic acid tablets. In some cases, liver transplantation may be considered according to medical advice.

In daily life, patients are advised to maintain healthy lifestyle habits, avoid overexertion, and balance work with rest. Regarding diet, it is recommended to eat light meals and avoid spicy or irritating foods.
