Many people with Ehlers-Danlos syndrome (EDS) or hypermobility spectrum disorder (HSD) also have a type of dysautonomia. There are different types of dysautonomia with different symptoms.
Dysautonomia, also called autonomic dysfunction, is a group of disorders that affect the autonomic nervous system.
People with EDS and HSD most commonly have a form of orthostatic intolerance. “Orthostasis” means to stand upright, so orthostatic intolerance refers to symptoms that occur due to standing up or being upright.
The two most common types of orthostatic intolerance are:
1️⃣ Orthostatic hypotension (OH) — low blood pressure on being upright.
2️⃣ Postural orthostatic tachycardia syndrome (POTS) — an abnormal increase in heart rate when standing without a drop in blood pressure.
Symptoms of dysautonomia include:
● Tachycardia (fast heart rate)
● Palpitations (feeling the heart racing or pounding)
● Hypotension (low blood pressure)
● Lightheadedness
● Presyncope (a sense of being about to faint)
● Syncope (fainting)
● Blurred vision
