What is amylase?

In this article

Amylase is a digestive enzyme that helps your body break down carbohydrates into simpler sugars. It is produced primarily by the pancreas and salivary glands, with approximately 40% coming from the pancreas and 60% from the salivary glands. While it is normal to have a small amount of amylase circulating in your blood and urine, abnormal levels can indicate underlying health conditions affecting your pancreas, salivary glands, or digestive system.

Why is amylase important?

Tracking your amylase levels is essential for understanding the health of your pancreas and digestive system. The pancreas plays a critical role in both digestion and blood sugar regulation, producing enzymes that help break down food and hormones like insulin that regulate glucose metabolism.

High amylase levels may indicate acute or chronic pancreatitis, which is inflammation of the pancreas. In acute pancreatitis, amylase levels can become four to six times higher than the upper limit of normal. Other conditions that may cause elevated amylase include gallstones, pancreatic duct obstruction, pancreatic cancer, mumps, or salivary gland infections. Symptoms of high amylase related to pancreatitis may include severe upper abdominal pain that radiates to the back, nausea, vomiting, fever, and loss of appetite.

Low amylase levels may suggest chronic pancreatitis with significant pancreatic damage, cystic fibrosis, liver disease, or kidney problems. Persistently low amylase values below 17.3 U/L have high specificity for chronic pancreatitis. If you are concerned with your levels, it is important to consult with your physician for proper diagnosis and treatment.

How can I better understand my amylase levels?

Blood (serum) amylase:

  • Normal: 30 to 110 U/L (units per liter)
  • Some laboratories use: 40 to 140 U/L
  • High: Greater than 110-140 U/L (depending on lab)
  • Acute pancreatitis: Typically 4-6 times the upper limit of normal
  • Low: Less than 30 U/L
  • Chronic pancreatitis indicator: Less than 17.3 U/L

Urine amylase:

  • Normal: 2.6 to 21.2 IU/h (international units per hour)
  • Alternative range: 24 to 400 U/L

Note: Normal ranges may vary between laboratories due to different testing methods. Always consult your healthcare provider for interpretation specific to your labโ€™s reference range.

Amylase test results are typically analyzed alongside other tests such as lipase, which is considered more specific for pancreatic disorders. Lipase tests are particularly useful for diagnosing pancreatitis, especially when caused by alcohol use. Your healthcare provider may also order imaging studies such as CT scans, ultrasound, or MRI to provide a complete picture of your pancreatic health.

Urine amylase levels rise later than serum levels and can remain elevated even after blood values return to normal, making urine tests particularly valuable for identifying pancreatitis in later stages of the disease.

How can I maintain optimal amylase levels?

If you need to maintain healthy amylase levels and support pancreatic function, consider the following strategies:

Dietary Changes: Focus on a low-fat, nutrient-dense diet that includes lean proteins, fruits, vegetables, whole grains, and low-fat dairy. Limit total fat intake to less than 30 grams per day and eliminate saturated fats. Avoid greasy, fried, and highly processed foods. Eating smaller, more frequent meals (5-6 per day) can reduce the workload on your pancreas. A Mediterranean diet pattern with emphasis on plant-based foods, whole grains, and lean proteins is beneficial for pancreatic health.

Lifestyle Changes: Avoid alcohol consumption, as excessive alcohol use is a leading cause of pancreatitis and elevated amylase levels. If you smoke, quit immediately, as smoking increases the risk of pancreatitis and pancreatic cancer. Stay well-hydrated by drinking plenty of water throughout the day, as adequate hydration supports normal enzyme function and helps flush toxins from the body. Maintain a healthy weight through regular physical activity, which improves insulin sensitivity and reduces inflammation.

Medical Management: If you have been diagnosed with pancreatic conditions, take prescribed pancreatic enzyme supplements regularly to prevent flare-ups and improve nutrient absorption. Follow up with your healthcare provider regularly to monitor your pancreatic function and amylase levels, especially if you have chronic pancreatitis or other pancreatic disorders.
