Pancreatic Amylase

Pancreatic amylase is a digestive enzyme produced by your pancreas. It plays a key role in breaking down complex carbohydrates (starches) in your food into simpler sugars that your body can absorb and use for energy.

What it is

Your pancreas is a gland located behind your stomach. It has two main jobs: producing digestive enzymes, like amylase, and producing hormones, such as insulin, that help regulate your blood sugar.

Amylase is released into your small intestine to help with digestion. A small amount of amylase is also normally present in your bloodstream. When the pancreas is inflamed or damaged, more amylase can be released into the blood, leading to higher levels than usual.

The typical reference range for pancreatic amylase in the UK is usually between 13–53 U/l. It's important to remember that laboratory reference ranges can vary slightly, and your GP will interpret your results in the context of your overall health.

Why it matters

Measuring pancreatic amylase levels in your blood can be a useful tool for your doctor. It can help them assess how well your pancreas is functioning and can be an indicator of certain pancreatic conditions.

Specifically, a significantly raised level of pancreatic amylase in the blood is often associated with inflammation of the pancreas, a condition known as pancreatitis. Pancreatitis can be acute (sudden and short-lived) or chronic (long-lasting).

What can cause it to be high or low

High levels:

The most common reason for a significant increase in pancreatic amylase is pancreatitis. This inflammation of the pancreas can be caused by various factors, including gallstones, heavy alcohol consumption, certain medications, high triglyceride levels, and abdominal injury.

Other conditions that can sometimes lead to elevated amylase levels include:

• Bowel obstruction or perforation: A blockage or tear in the intestines can affect pancreatic function.
• Certain infections: Some infections can indirectly impact the pancreas.
• Kidney problems: If the kidneys aren't filtering waste effectively, amylase can build up in the blood.
• Some cancers: In rarer cases, certain cancers affecting the pancreas or surrounding areas might be associated with higher amylase.
• Ectopic pregnancy: A pregnancy developing outside the uterus.
• Diabetic ketoacidosis (DKA): A serious complication of diabetes.

Low levels:

Low levels of pancreatic amylase are generally less common and often less concerning than high levels. They might be associated with:

• Severe, long-standing pancreatitis: In chronic pancreatitis, the pancreas can become so damaged that it loses its ability to produce sufficient enzymes.
• Certain genetic conditions: Some rare inherited disorders can affect enzyme production.
• Pancreatic insufficiency: A general term for the pancreas not producing enough digestive enzymes.

Lifestyle factors that may help

For individuals concerned about pancreatic health, certain lifestyle adjustments can be beneficial and are often discussed with healthcare professionals:

• Dietary choices: Focusing on a balanced diet that is lower in unhealthy fats and processed foods can support overall digestive health. Discussing dietary patterns with a dietitian or your GP might be helpful.
• Alcohol intake: Limiting or avoiding alcohol consumption is often recommended, as excessive alcohol is a significant risk factor for pancreatitis.
• Hydration: Staying well-hydrated by drinking plenty of water is important for general bodily functions, including digestion.
• Weight management: Maintaining a healthy weight can reduce the risk of conditions like gallstones and high triglycerides, which can impact the pancreas.
• Smoking cessation: Smoking is a known risk factor for various health problems, including pancreatic issues.

Questions to discuss with your GP

If you have concerns about your pancreatic amylase levels or your pancreatic health, it's always best to have a conversation with your GP. Here are some questions you might consider discussing:

• What does my pancreatic amylase result mean in the context of my overall health?
• Are there any specific lifestyle changes you would recommend for me to support my pancreatic health?
• What are the potential causes of my amylase level being higher or lower than the reference range?
• Are there any further tests or investigations you think would be beneficial for me?
• What are the signs and symptoms of pancreatitis I should be aware of?
• How often should my pancreatic amylase levels be monitored, if at all?
