What Came First: Digestive Issues or Eating Disorders?

What Came First: Digestive Issues or Eating Disorders?



When it comes to eating disorders and digestive issues, it is often unclear which one came first. Some individuals with digestive issues may develop an eating disorder as a coping mechanism, while others with eating disorders may experience digestive symptoms as a result of their disorder. This has led to a debated topic among scientists, clinicians, and individuals alike. Today, we will explore this topic and see if it is the chicken or the egg: Do GI issues cause eating disorders, or does the eating disorder cause GI issues?


The biopsychosocial model, developed by Dr. Douglas Drossman, suggests that both physical and psychological factors can contribute to the development of functional GI disorders and eating disorders. According to Dr. Drossman, negative emotions such as anxiety and stress can contribute to digestive symptoms, which can then lead to the development of an eating disorder. Alternatively, restricting food intake or engaging in purging behaviors can also worsen digestive symptoms.


A recent study by Zimmerman and colleagues found that individuals with functional GI disorders had a higher prevalence of eating disorders compared to those without GI issues. This suggests that individuals with digestive issues may be at a greater risk for developing eating disorders. Additionally, restrictive eating patterns can cause changes in gut motility and intestinal permeability, further exacerbating GI symptoms.


Conversely, individuals with eating disorders may also experience digestive symptoms as a result of their disorder. Bulimia nervosa, in particular, is associated with GI complications such as esophagitis, gastritis, and intestinal problems. The frequent purging behaviors associated with bulimia can cause electrolyte imbalances and lead to dehydration, which can further damage the digestive system.


Another study by Mahony and colleagues found that approximately 40% of individuals with anorexia nervosa had lower GI symptoms. These symptoms, such as constipation and bloating, may be due to the lack of nutrient-dense foods in their diet and low levels of physical activity.


In conclusion, it seems that both digestive issues and eating disorders can contribute to each other's development. Negative emotions, restrictive eating patterns, and purging behaviors can all worsen GI symptoms and lead to the development of a functional GI disorder. Conversely, digestive symptoms can also occur as a result of an eating disorder, particularly when purging behaviors are involved. It is important for clinicians to address both physical and psychological factors when treating individuals with digestive issues and eating disorders, as they may have a bi-directional relationship. By addressing both, clinicians can help individuals achieve better overall health and wellness.

A Functional Medicine Approach to SIBO and Methane Overgrowth

  A Functional Medicine Approach to SIBO and Methane Overgrowth Small Intestinal Bacterial Overgrowth (SIBO) and its methane-dominant form—now termed Intestinal Methanogen Overgrowth (IMO)—are key contributors to chronic digestive complaints such as bloating, constipation, and abdominal discomfort. While conventional treatment often relies on symptom suppression or singular pharmaceutical approaches, the functional medicine model aims to uncover the root causes behind these overgrowths and restore balance to the gut ecosystem. By integrating advanced testing, targeted nutrition, herbal antimicrobials, and motility support, this approach provides both relief and resilience.   Understanding SIBO and Methane Overgrowth SIBO is characterized by an abnormal increase in the population of bacteria in the small intestine, typically resulting from impaired motility, post-infectious changes, or structural anomalies. In contrast, IMO is caused by an overgrowth of archaea, such as Methan...
  Navigating Travel Constipation: Tips for Maintaining Digestive Health on the Go Traveling—whether for leisure or business—can be exhilarating, but for many, it also disrupts a crucial part of daily wellness: regular bowel movements.  Travel constipation is a common yet often overlooked condition that affects both frequent flyers and occasional vacationers.  Understanding its causes and implementing preventive strategies can help support gut health, ensuring your journey is as comfortable as it is memorable. What Causes Travel Constipation? Constipation during travel is typically multifactorial. The primary contributing factors include: Changes in routine : Our digestive system thrives on regularity. Travel often alters meal times, sleep schedules, and bathroom habits, disrupting the body’s natural rhythm (Staller, 2017). Dehydration : Long flights, hot climates, and increased caffeine or alcohol intake can lead to fluid loss, reducing the wa...

The Rising Tide of Digestive Disorders: A Functional Perspective on Modern Root Causes

  The Rising Tide of Digestive Disorders: A Functional Perspective on Modern Root Causes Digestive disorders have become increasingly prevalent over the past decade, with rising rates of irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), colorectal cancer in younger adults, and functional gastrointestinal disorders (FGIDs). While genetics play a role, the sharp increase in prevalence over a short period suggests significant environmental and lifestyle shifts as key drivers. From depleted soil nutrients to modern dietary patterns, chronic stress, trauma, and toxic exposures, a functional medicine lens helps us connect these dots in understanding why our collective gut health is under strain.   1. Decreased Mineral Density in Soil The modern industrialized food system emphasizes yield and efficiency, often at the expense of soil quality. Over time, the mineral content of soil has declined, reducing the nutritional value of produce. Hooda et al. (2004) highlight ho...
