Constipation is a common issue related to the gastrointestinal (GI) tract, affecting over four million Americans. A diet lacking in balance, particularly in certain micronutrients, has been associated with constipation. This article will explore micronutrients, constipation, and how imbalances in micronutrients may contribute to constipation. Functional medicine testing can help identify micronutrient imbalances that might be related to constipation and suggest potential options for management based on results.

What are Micronutrients?
Micronutrients are vitamins and minerals ideally obtained from the diet. Micronutrients are crucial for various bodily functions, including cellular growth and repair, energy production, metabolism, and immune function. Because of this, imbalances in micronutrients may be linked to issues like chronic fatigue, chronic pain, infertility, cardiovascular concerns, metabolic issues, digestive disorders, and more. Micronutrients can be divided into fat-soluble vitamins, water-soluble vitamins, macrominerals, and trace minerals.
What is Constipation?
Constipation is a common gastrointestinal (GI) complaint, with 16 out of every 100 Americans experiencing it. Symptoms may include painful stools, difficulty passing stools, or infrequent bowel movements (less than three per week). Constipation can also be associated with bloating, gas, and abdominal cramping.
How Do Micronutrient Imbalances Affect Constipation?
Micronutrients may influence the movement of water in the GI tract, which can impact stool consistency. They might also affect the rate of movement, or motility, throughout the GI tract. Each specific micronutrient plays a role in healthy digestion, so imbalances could potentially affect the GI tract in ways that may contribute to constipation.
Which Micronutrient Imbalances Are Associated With Constipation?
Micronutrients can be present in both low and high levels, and both excesses and deficiencies of certain micronutrients may be linked to constipation.
Micronutrient Excess That May Contribute to Constipation
Excessive levels of certain micronutrients might contribute to constipation by affecting gut motility, altering water balance in the intestine, or interfering with the absorption of other essential nutrients. Here are some examples:
Iron Excess
Iron is a mineral important for development and growth. It is essential for creating hemoglobin, which carries oxygen in the blood. Iron supplementation is common, especially in pregnant women, but one potential side effect is constipation. It is thought that iron may draw water away from the GI tract, leading to harder stools. Different forms of iron supplements, such as ferrous glycine sulfate, might be gentler on the GI tract.
Calcium Excess
Calcium is essential for strong bones, muscle contractions, nerve signaling, hormone release, and blood flow. However, calcium's effect on muscle contraction can slow stool transit in the GI tract, potentially leading to constipation. Calcium carbonate is often noted as a form that may be more likely to contribute to constipation.
Vitamin D Excess
Many Americans are estimated to be deficient in vitamin D, which can affect bone health, immune function, and energy levels. Supplementation is common, especially in northern regions. However, excessive vitamin D can lead to high calcium levels in the blood, which may contribute to constipation.
Zinc Excess
Excess zinc intake might interfere with the absorption of other nutrients, such as copper and iron, which are important for maintaining bowel regularity. Sources of zinc include oysters, red meat, poultry, beans, nuts, and fortified cereals.
Micronutrient Deficiencies That May Contribute to Constipation
Micronutrient deficiencies can affect the digestive system's proper functioning. Here are some examples:
Vitamin D Deficiency
Low vitamin D levels may affect gastric motility or movement in the GI tract, potentially leading to constipation.
Thiamine/B1 Deficiency
Thiamine, or vitamin B1, is important for cellular growth and development. Deficiencies, though rare in the U.S., can reduce digestive enzyme production, potentially slowing the digestive tract and contributing to constipation.
Potassium Deficiency
Potassium is crucial for cellular fluidity and signaling. A deficiency may slow GI tract motility, and in severe cases, it may significantly impact bowel movements.
Magnesium Deficiency
Magnesium is involved in many bodily reactions. It is often used to support digestive health, and studies suggest low magnesium levels may be associated with constipation. Magnesium helps draw water into the stool, softening it and supporting GI tract movement.
Vitamin C Deficiency
Vitamin C deficiency may affect the intestinal lining's function. It also helps increase stool water content. Sources include citrus fruits, berries, kiwi, peppers, and broccoli.
Functional Medicine Labs to Explore Causes of Constipation
Micronutrient imbalances related to constipation can result from various factors. A micronutrient panel and comprehensive stool analysis may help identify underlying causes.
Micronutrient Panel
A micronutrient test can help assess levels of various vitamins and minerals, identifying both deficiencies and excesses. Understanding these levels can provide insights into potential interactions and imbalances.
Comprehensive Stool Test
Comprehensive stool tests evaluate gastrointestinal functioning, including digestion, absorption, and microbiome composition. These tests can help identify issues that may contribute to micronutrient imbalances and constipation.
Nutrition for Constipation
The Mediterranean Diet may support micronutrient balance and digestive health. It includes whole foods, unprocessed grains, and healthy fats, providing a variety of nutrients. The diet is also rich in fiber, which can help support regular bowel movements.
Hydration for Constipation
Staying hydrated is important for digestive health. Dehydration can lead to harder stools and may affect nutrient absorption, potentially contributing to constipation.
Microbiome Support for Constipation
Comprehensive stool testing can help create a targeted plan to support areas of the GI tract that may not be functioning optimally, potentially addressing micronutrient imbalances.
Supplements for Constipation
Digestive enzymes are produced by the stomach, liver, and pancreas to help break down foods. If digestion markers are low, enzyme supplements may support food breakdown and absorption.
Intestinal Permeability
L-glutamine is an amino acid that may support the integrity of the intestinal lining, potentially reducing permeability.
Inflammation
Boswellia serrata is a plant that contains compounds which may help manage inflammation. In a study of people with Crohn's disease, Boswellia was compared to a standard treatment, showing potential benefits in managing symptoms.
Dysbiosis
Dysbiosis refers to an imbalance in gut bacteria. Probiotics may help support a healthy balance of gut microbes.
Summary
Constipation is a common GI issue, and many seek ways to manage it. Exploring micronutrient levels, as both high and low levels can be associated with constipation, may help in addressing the issue. Micronutrient and comprehensive gastrointestinal testing can provide insights into potential imbalances and digestive function.
