Can EPI Cause Vitamin Deficiencies?
Exocrine Pancreatic Insufficiency (EPI) affects the body’s ability to digest food properly. Because digestion and nutrient absorption are closely connected, EPI can also affect nutritional health.
One potential complication is low levels of certain vitamins, particularly fat-soluble vitamins A, D, E, and K.
The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) notes that EPI-related malabsorption can lead to low levels of fat-soluble vitamins as well as other nutritional complications.
Understanding this connection can help you have more informed conversations with your healthcare provider. Nutrition education, including the support available through My EPI Plan for eligible patients, can also help you better understand the relationship between digestion and nutrition.
Why Can EPI Affect Vitamin Absorption?
The pancreas produces digestive enzymes that help break down carbohydrates, proteins, and fats.
When someone has EPI, the pancreas may not provide enough digestive enzymes to properly digest food. This can lead to malabsorption, meaning the body may not absorb nutrients as effectively.
Fat digestion is particularly important when it comes to vitamins A, D, E, and K because these vitamins are fat-soluble.
When fat digestion and absorption are impaired, vitamin levels may also be affected.
Which Vitamins Can Be Affected by EPI?
Vitamin A
Vitamin A supports several important functions in the body, including normal vision and immune function.
Low vitamin A levels can have health consequences, which is why your healthcare provider may monitor nutritional status when appropriate.
Vitamin D
Vitamin D plays an important role in maintaining healthy bones and supporting normal muscle and immune function.
Because EPI can be associated with low levels of fat-soluble vitamins, vitamin D status may be an important consideration for some people with EPI.
Vitamin E
Vitamin E is an antioxidant that helps protect cells from oxidative damage.
Like vitamins A, D, and K, vitamin E is fat-soluble and can be affected when fat digestion and absorption are impaired.
Vitamin K
Vitamin K is important for normal blood clotting and bone health.
Changes in nutrient absorption can potentially affect vitamin K levels.
If you’re concerned about vitamin deficiencies, talk with your healthcare provider before taking supplements.
Does Everyone With EPI Develop Vitamin Deficiencies?
No.
EPI affects people differently, and not everyone with EPI will develop nutritional deficiencies.
Your risk can depend on factors such as the severity of EPI, the underlying cause, your nutritional status, and whether your EPI is appropriately treated.
Your healthcare provider can determine whether you need nutritional testing or supplementation.
NIDDK notes that healthcare providers may monitor people with EPI for complications such as malnutrition and low levels of vitamins A, D, E, and K.
What Are Signs of a Nutritional Deficiency?
Vitamin deficiencies don’t always cause obvious symptoms.
Depending on the nutrient involved, potential signs of nutritional problems may include:
- Fatigue
- Weakness
- Changes in vision
- Changes in bone health
- Unintended weight loss
- Other changes in overall health
These symptoms can have many different causes and do not necessarily mean you have a vitamin deficiency.
If you’re experiencing persistent symptoms, discuss them with your healthcare provider.
Can EPI Treatment Help With Nutrient Absorption?
Treatment for EPI commonly includes pancreatic enzyme replacement therapy (PERT).
PERT provides digestive enzymes that help the body digest food. NIDDK states that PERT can improve EPI symptoms and help people obtain enough nutrients from what they eat and drink.
Your healthcare provider will determine whether PERT is appropriate for you and provide instructions about how to use it.
What Role Does Nutrition Play in EPI?
Nutrition can be an important part of managing EPI and maintaining overall health.
However, there isn’t one universal diet that’s right for everyone with EPI.
Your individual nutrition needs may depend on:
- Your symptoms
- Your nutritional status
- The underlying cause of EPI
- Your treatment plan
- Other health conditions
A registered dietitian can provide individualized nutrition education and help you better understand your nutritional needs.
My EPI Plan is designed to give eligible patients access to nutrition-focused counseling with a registered dietitian. The program can provide an opportunity to discuss questions about nutrition, digestion, and making positive nutritional decisions as part of your daily routine.
Should You Take Vitamin Supplements If You Have EPI?
Not necessarily.
Although some people with EPI may need vitamin or other nutritional supplements, supplementation should be based on your individual needs and healthcare provider’s recommendations.
Taking large amounts of certain vitamins can be harmful.
If you have EPI and are concerned about your vitamin levels, talk with your healthcare provider about whether testing or supplementation may be appropriate.
How Can Nutrition Education Help?
Living with EPI can come with plenty of questions:
Am I getting enough nutrients?
Should I change what I eat?
Do I need supplements?
How does EPI affect digestion?
What should I discuss with my healthcare provider?
Nutrition education can help you better understand these questions without relying on generalized advice found online.
For eligible patients, My EPI Plan provides access to nutrition-focused counseling with a registered dietitian, offering an opportunity to discuss individual nutrition questions and strategies.
