A low level can indicate pancreatic insufficiency, a condition where the pancreas does not produce enough digestive enzymes. Understanding the causes and symptoms of low fecal elastase-1 can help you and your healthcare provider make informed decisions about your health.
What is fecal elastase-1?
Fecal elastase-1 is an enzyme produced by the pancreas. It plays a crucial role in breaking down proteins in the digestive system. This enzyme is measured in a stool sample to evaluate how well the pancreas is functioning. A normal fecal elastase-1 level is greater than 200 µg/g. Levels between 100 and 200 µg/g indicate moderate pancreatic insufficiency, while levels below 100 µg/g suggest severe pancreatic insufficiency.
Causes of low fecal elastase-1
Low fecal elastase-1 levels are typically caused by pancreatic insufficiency. This condition can result from chronic pancreatitis, cystic fibrosis, or pancreatic cancer. Chronic pancreatitis is a long-term inflammation of the pancreas that can lead to permanent damage. Cystic fibrosis is a genetic disorder that affects the lungs and digestive system, often leading to pancreatic insufficiency. Pancreatic cancer can also impair the pancreas's ability to produce enzymes, resulting in low fecal elastase-1 levels.
Symptoms of pancreatic insufficiency
Symptoms of pancreatic insufficiency can include diarrhea, weight loss, and malnutrition. These symptoms occur because the body is unable to properly digest and absorb nutrients. Fatty stools, known as steatorrhea, are another common symptom, as undigested fats pass through the digestive system. If you experience these symptoms, it is important to consult with a healthcare provider for further evaluation.
How to interpret fecal elastase-1 results
Interpreting fecal elastase-1 results involves understanding the enzyme levels in your stool sample. A level greater than 200 µg/g is considered normal. Levels between 100 and 200 µg/g suggest moderate pancreatic insufficiency, while levels below 100 µg/g indicate severe insufficiency. If your results show low fecal elastase-1, it is essential to discuss the findings with your healthcare provider to determine the underlying cause and appropriate treatment.
Frequently asked questions
What is a normal level of fecal elastase-1?
A normal level of fecal elastase-1 is greater than 200 µg/g.
What can cause low fecal elastase-1 levels?
Low levels can be caused by conditions such as chronic pancreatitis, cystic fibrosis, or pancreatic cancer.

When to see a doctor
If you experience symptoms such as persistent diarrhea, unexplained weight loss, or signs of malnutrition, it is important to see a doctor. These symptoms may indicate pancreatic insufficiency or another underlying condition that requires medical attention. Your doctor can help determine the cause of your symptoms and recommend appropriate tests and treatments.
