What is ehlers danlos syndrome

Last updated: April 1, 2026

Quick Answer: Ehlers-Danlos Syndrome (EDS) is a group of genetic disorders affecting connective tissue, caused by defects in collagen production or structure. It results in symptoms including joint hypermobility, skin fragility, and chronic pain.

Key Facts

EDS is a genetic connective tissue disorder affecting collagen production or function
There are at least 13 recognized types of EDS, each with distinct genetic and clinical features
Common symptoms include joint hypermobility, elastic skin, easy bruising, and chronic pain
EDS affects approximately 1 in 2,500 to 1 in 5,000 people worldwide
Management typically involves physical therapy, pain management, and lifestyle modifications rather than curative treatment

What is Ehlers-Danlos Syndrome?

Ehlers-Danlos Syndrome (EDS) is a group of inherited genetic disorders characterized by defects in collagen synthesis or structure. Collagen is a crucial protein providing structural support and strength to connective tissues throughout the body, including skin, joints, tendons, ligaments, and blood vessels. When collagen is defective or insufficient, these tissues become unusually fragile and stretchy, leading to the wide range of symptoms associated with EDS.

Types of EDS

EDS encompasses at least 13 types, classified by their genetic basis and clinical presentation. The Classical type is characterized by soft, velvety skin and significant joint hypermobility. The Hypermobility type (hEDS) is the most common form, featuring extreme flexibility and joint pain. The Vascular type (vEDS) is the most severe, involving fragile blood vessels prone to rupture. Other types include Kyphoscoliotic, Arthrochalasia, and Periodontal types, each with distinctive features and inheritance patterns.

Symptoms and Clinical Features

Common symptoms across EDS types include joint hypermobility (excessive range of motion), chronic pain and fatigue, elastic or velvety skin, easy bruising and slow wound healing, and heart and vascular complications in severe forms. Some individuals experience gastrointestinal problems, eye issues, and neurological symptoms. Symptom severity varies considerably between types and individuals, with some experiencing mild symptoms while others face serious complications affecting quality of life.

Diagnosis and Management

EDS diagnosis typically involves clinical evaluation, genetic testing, and sometimes skin biopsy. There is currently no cure for EDS; management focuses on symptom relief and complication prevention. Treatment strategies include physical therapy and specialized exercise, pain management techniques, bracing or taping for joint stability, and lifestyle modifications. Regular monitoring by multidisciplinary medical teams helps manage potential complications and optimize quality of life for individuals with EDS.
