What Is Ehlers-Danlos Syndrome?
Ehlers-Danlos syndromes (EDS) are a class of genetic diseases affecting connective tissue, including collagen and other proteins that provide strength and support to ligaments, muscles, and skin. Protein changes increase these structures' flexibility or "stretchiness."
EDS has various types, each with unique physiological effects. Hypermobile Ehlers-Danlos syndrome (hEDS), formerly known as joint hypermobility syndrome or EDS type III, is the most prevalent kind. Elastic skin and extremely flexible joints are characteristics of hEDS. This kind frequently exhibits symptoms that impact other organs, such as the stomach and the musculoskeletal system. The impact of hEDS varies greatly from person to person, and its real occurrence is unknown.
How Does EDS Affect the Digestive System?
In individuals with hypermobile Ehlers-Danlos syndrome (hEDS), abnormalities in connective tissue throughout the digestive tract can impact its function. This includes affecting the mechanical movements necessary for digestion and increasing gut sensitivity due to connective tissue anomalies around the nerves. Although hEDS may differ from other EDS subtypes in digestive function, diagnostic biomarkers for these issues have yet to be identified, and more research is needed.
The digestive tract is divided into the upper and lower parts: the upper digestive tract includes the esophagus, stomach, and duodenum, while the lower digestive tract comprises the small intestine, large intestine, colon, and rectum. hEDS patients may experience symptoms in either or both parts of the digestive system, with some studies indicating that gastrointestinal symptoms are common in hEDS
What Are the Various Types of Gut Problems Arising Due to EDS?
-
Digestion symptoms in people with hypermobile Ehlers-Danlos syndrome (hEDS) can differ greatly in type, frequency, and intensity from person to person.
-
Upper gastrointestinal problems frequently mentioned include acid reflux, persistent or recurrent indigestion, pain or discomfort, and early satiety after meals.
-
Symptoms of the lower digestive tract can include diarrhea, bloating, constipation, and an overall sensation of discomfort in the abdomen.
-
Acid reflux, recurrent or chronic dyspepsia (indigestion), pain or discomfort, and early mealtime satiety are among the upper digestive system problems that are frequently mentioned.
-
Constipation, diarrhea, bloating, abdominal pain, and an overall sensation of discomfort in the abdomen are some of the symptoms found in the lower digestive tract.
-
Any of these symptoms may be accompanied by nausea and vomiting.
1. Delayed Gastric Emptying or Dysmotility - Dysmotility refers to abnormal movement of the gut, like spasms. In people with hEDS, this can manifest as delayed gastric emptying, where the stomach empties more slowly than usual. This condition can vary in severity, with the most severe form being gastroparesis(a near-paralysis of stomach movement). Only a few people develop gastroparesis. Although a clear connection between hEDS and gastroparesis has not been demonstrated, symptoms including bloating, nausea, and vomiting might indicate testing for delayed gastric emptying. Increased sensitivity in the stomach can cause problems including acid reflux, bile reflux, bloating, early satiety, and nausea in certain hEDS patients.
2. Bloating - Abdominal bloating is a typical symptom of hEDS. Bloating may result from bacterial overgrowth in the small intestine brought on by constipation and bowel stasis, which can cause excessive food fermentation and gas generation. However, more investigation is required to establish a conclusive connection between bacterial overgrowth and hEDS.
3. Constipation - People with EDS frequently experience constipation, which is due to slow colonic movement and difficulty in emptying the bowels. Constipation can be caused by other variables like food, hormonal or neurological illnesses, side effects from medications (particularly opioid painkillers), and physical disorders, including prolapse (protruding organ due to weakened muscles) of the rectum or bowel.
4. Heartburn -As per research, hiatus hernia at the lower end of the esophagus is more common in people with hEDS. The upper end of the stomach slips into the chest cavity through a little hole in the diaphragm, resulting in a hiatus hernia. While hiatus hernias are quite common and usually not harmful, they can cause acid reflux and heartburn, resulting in gastroesophageal reflux disease (GERD) by impairing the function of the muscle that stops stomach contents from returning into the esophagus. However, reflux and heartburn may develop without a hiatus hernia. They may be associated with dysmotility and esophageal hypersensitivity (the threshold for pain perception becomes lower for the esophagus) or may occur independently.
What GI Symptoms Are Present in Other EDS Subtypes?
Apart from hEDS, other subtypes of Ehlers-Danlos syndrome have also demonstrated gastrointestinal (GI) symptoms.
-
Classical EDS (cEDS) - Patients develop diverticular disease characterized by tiny pockets in the bowel.
-
Vascular EDS (vEDS) -
-
Gastrointestinal problems include bleeding and organ perforation (such as the stomach, small intestine, or esophagus).
-
During a colonoscopy (procedure to check inside the long intestine or colon), there is a higher chance of large intestine perforation and post-operative problems such as gut artery obstruction. In severe circumstances, vEDS can also result in aberrant diaphragm form and liver and spleen rupture.
-
-
Tenascin-X Deficiency (Classical-Like EDS) -
-
GI symptoms consist of diminished intestinal motility, pain in the abdomen, and complications following surgery, such as hernias (abnormal bulging of any organ) and perforations.
-
In addition, patients could experience stomach hernias, uterine prolapse (occurs due to weakening of pelvic muscles), diverticular disease (small pockets in the bowel), and persistent constipation.
-
Similar gastrointestinal problems, such as rectal prolapse (slipping of the rectum into the anus) and a history of persistent constipation throughout childhood, have been seen to be more common among family members.
-
How Are Gastrointestinal Issues Managed in EDS?
Currently, there are no guidelines for treating the GI symptoms of Ehlers-Danlos syndrome (EDS). Hence, clinical experience, best practices, and available evidence determine the treatment.
-
Nutrition & Diet: GI symptoms like diarrhea, bloating, and pain are common in hEDS and frequently coexist with irritable bowel syndrome (IBS). Dietary adjustments, such as the low FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols poorly absorbed by the intestine) diet, have shown promise in controlling these symptoms. However, additional investigation is required to provide definite answers.
-
Surgical Management: Given the possibility of complications, a cautious approach is advised in cases of vascular EDS with acute GI problems (such as bleeding or perforation). While non-surgical therapy is preferred when it is feasible, surgery should be carefully evaluated. Surgical procedures must be performed carefully since the tissues become fragile in EDS.
-
Desmopressin: When administered to treat bleeding symptoms in patients with hEDS, desmopressin has been shown to shorten bleeding times and minimize surgical complications. However, more research is required to validate its efficacy and provide a uniform treatment plan.
-
Pain Management: Since pain is common in patients with EDS, it may be better to manage it without using opioids to prevent GI symptoms from getting worse. Alternative approaches to managing pain need to be investigated.
-
Specialist Care: Due to the complex relationship between symptoms and possible structural abnormalities, patients with hEDS and GI conditions may need multidisciplinary therapy. Experts in pain management, gastrointestinal, and other areas may be involved.
Anatomical and functional abnormalities that may coexist with EDS should be identified and addressed to customize the treatment plan and enhance the quality of life for these individuals.
Conclusion
In conclusion, a strong correlation between gastrointestinal (GI) symptoms and Ehlers-Danlos syndromes (EDS) is becoming more and more evident. Prolapse, hernias, abnormal gastrointestinal motility, and organ displacement are common in EDS patients. Gastrointestinal problems like indigestion and irritable bowel syndrome are common in those with hypermobile EDS (hEDS). The impact of these symptoms on the quality of life can be significant. GI problems and EDS are known to be related, yet there are no evidence-based recommendations for treating these symptoms in EDS patients. More investigation is required to understand the underlying processes and create customized treatment plans.
