Laboratory report: Elevated levels of bilirubin and amylase?
In the past two years, direct bilirubin and amylase levels have frequently been slightly elevated, while other liver, gallbladder, and blood/urine values remain normal.
There has been a long-term history of right upper abdominal pain and bloating for about ten years.
Last year, a colonoscopy, gastroscopy, abdominal ultrasound, and abdominal MRI were performed, which revealed gastroesophageal reflux disease and mixed hemorrhoids, but no other issues were found.
The physician later assessed that it might be functional dyspepsia.
Currently, the abdominal pain continues to recur, and I am uncertain how to interpret the abnormal values or how to proceed with monitoring.
Thank you!
2020/09/16: Total bilirubin 1.8, direct bilirubin 0.3

Hello! Abnormal levels of bilirubin and amylase suggest that you should follow up with a gastroenterologist specializing in liver and biliary disorders.
Additionally, dietary habits are very important, and it is recommended that you reduce your intake of animal fats.

More Info
Elevated levels of bilirubin and amylase can be concerning for patients, especially when they are persistent or accompanied by symptoms. Understanding the implications of these elevated levels is crucial for managing your health effectively.
Bilirubin Levels:
Bilirubin is a yellow compound that is produced during the normal breakdown of red blood cells. It is processed by the liver and excreted in bile. Elevated bilirubin levels can indicate several conditions, including liver dysfunction, bile duct obstruction, or hemolysis (increased breakdown of red blood cells). In your case, with total bilirubin levels fluctuating around 1.8 mg/dL, which is slightly above the normal range, it’s essential to consider the following:
1. Direct vs. Indirect Bilirubin: The direct (conjugated) bilirubin level is particularly important. Elevated direct bilirubin can suggest liver or bile duct issues, while elevated indirect (unconjugated) bilirubin may indicate hemolysis or Gilbert's syndrome, a benign condition.
2. Symptoms and History: You mentioned having long-term right upper abdominal pain and bloating. This could suggest a chronic condition affecting your liver or gallbladder. Given your history of gastroesophageal reflux disease (GERD) and mixed hemorrhoids, it’s essential to consider whether these gastrointestinal issues could be contributing to your symptoms.
3. Follow-Up Testing: Since you have undergone various imaging studies (ultrasound, MRI) and endoscopies, it may be beneficial to continue monitoring your liver function tests, including bilirubin levels, and consider additional tests such as a liver function panel or even a liver biopsy if clinically indicated.
Amylase Levels:
Amylase is an enzyme that helps digest carbohydrates and is primarily produced by the pancreas and salivary glands. Elevated amylase levels can indicate several conditions, including:
1. Pancreatitis: Acute or chronic inflammation of the pancreas can cause significant increases in amylase. However, since your lipase levels were not mentioned as elevated, and you have no acute symptoms of pancreatitis (such as severe abdominal pain, nausea, or vomiting), it may not be the primary concern.
2. Other Causes: Elevated amylase can also result from conditions such as salivary gland inflammation (like mumps), gastrointestinal perforation, or even certain medications. Given your history of functional dyspepsia, it’s possible that your digestive issues could be contributing to the elevated amylase levels.
3. Monitoring and Management: Since your amylase levels have fluctuated but are not consistently high, it may be beneficial to monitor these levels periodically. If you experience any new symptoms, such as severe abdominal pain or changes in bowel habits, further evaluation may be warranted.
Next Steps:
Given your ongoing symptoms and the fluctuations in your lab results, it would be prudent to:
- Consult a Gastroenterologist: A specialist can provide a more in-depth evaluation of your symptoms and lab results. They may recommend additional tests or imaging studies to rule out any underlying conditions that could be causing your symptoms.
- Consider Dietary and Lifestyle Modifications: Sometimes, functional dyspepsia can be managed with dietary changes, stress management, and medications that reduce stomach acid or improve motility.
- Regular Monitoring: Keep track of your symptoms and lab results. Regular follow-ups with your healthcare provider can help identify any trends or changes that may require intervention.
In conclusion, while slightly elevated bilirubin and amylase levels can be concerning, they must be interpreted in the context of your overall health, symptoms, and medical history. Continued monitoring and consultation with healthcare professionals will be key to managing your condition effectively.
