Elevated Amylase Levels: Causes and Concerns - Gastroenterology and Hepatology

More Info

---

Elevated amylase levels can be concerning, especially when accompanied by symptoms such as abdominal discomfort, changes in bowel habits, and weight loss. In your case, the significant rise in amylase levels to 426 U/L, followed by subsequent readings that remained elevated, suggests a potential issue with the pancreas or related gastrointestinal structures.
Amylase is an enzyme primarily produced by the pancreas and salivary glands, and its elevation is most commonly associated with pancreatitis, which can be acute or chronic. Acute pancreatitis can occur due to various factors, including gallstones, alcohol consumption, certain medications, and, as in your case, dietary indiscretions such as consuming spoiled food. The fact that you experienced gastrointestinal symptoms after eating the spoiled rice dumpling raises the possibility that your body reacted to the foodborne illness, leading to inflammation of the pancreas.

The symptoms you described, including abdominal bloating and discomfort, fever, and changes in stool color, are consistent with gastrointestinal distress. The presence of yellow and green stools may indicate bile involvement, which can occur if the bile duct is obstructed or if there is an issue with bile production or secretion. However, the normalization of your stool after a few days suggests that the acute phase of your gastrointestinal upset may have resolved.

Your concern about pancreatic cancer, given the elevated amylase levels, is understandable. However, it is important to note that elevated amylase alone is not diagnostic of cancer. In fact, conditions such as pancreatitis, salivary gland disorders, and even certain medications can lead to increased amylase levels. The CA19-9 tumor marker, which you mentioned was within normal limits during your last check-up, is more specific for pancreatic cancer but is not definitive on its own. Elevated CA19-9 can also be seen in other conditions, including cholestasis and pancreatitis.

Given that your imaging studies (CT scan) showed no abnormalities in the pancreas, this is reassuring. It suggests that there is no acute structural issue, such as a tumor or significant inflammation. However, the persistence of elevated amylase levels warrants further investigation. It would be prudent to consider additional tests, such as:
1. Ultrasound of the abdomen: This can help visualize the pancreas and surrounding structures for any signs of gallstones or other abnormalities.

2. Endoscopic retrograde cholangiopancreatography (ERCP): If there is suspicion of a bile duct obstruction, this procedure can help visualize and potentially treat any issues.

3. Further blood tests: Checking for other pancreatic enzymes (like lipase), liver function tests, and possibly genetic markers if there is a family history of pancreatic disease.

In terms of your psychological well-being, it is crucial to address the anxiety and stress you are experiencing. Weight loss and decreased appetite can be exacerbated by anxiety, and it may be beneficial to speak with a mental health professional or a dietitian who can help you manage these symptoms and provide strategies for coping with your health concerns.

In summary, while elevated amylase levels can indicate pancreatitis or other pancreatic issues, the absence of pain, normal imaging, and the normalization of some symptoms are positive signs. Continuous monitoring and further investigations, as well as addressing any psychological impacts, will be key in managing your health moving forward. Always consult with your healthcare provider for personalized advice and treatment options.
