hEDS and Fatigue: Why Hypermobility Is So Exhausting

People hear "hypermobile" and picture party tricks — thumbs to wrists, elbows that bend the wrong way. What almost nobody outside the community realises is that fatigue is one of the most commonly reported symptoms in hypermobile Ehlers-Danlos syndrome, and for many people it's more disabling day to day than the joint pain itself.

Here's the part that tends to land: your muscles are doing a job your ligaments were supposed to be doing. All day. Every day. Including right now, while you sit reading this.

💪 The muscles-doing-overtime problem

In a typical joint, ligaments provide passive stability — they hold things in place without any energy cost, the way a well-built shelf holds books without effort. When connective tissue is more lax, that passive stability is reduced, and the surrounding muscles take over the job actively.

Active stabilisation costs energy. Standing, sitting upright, holding a phone, keeping your head balanced on your neck — tasks that are essentially free for most people become low-level continuous muscular work for you. It never fully switches off, which is why hEDS fatigue often feels less like tiredness and more like having run a background process all day.

🔁 The other four contributors

Poor sleep quality

Joint pain, subluxations that happen during sleep, and difficulty finding a comfortable position all fragment sleep — and fragmented sleep is not the same as restorative sleep, even when the hours on the clock look adequate.

Overlapping dysautonomia

POTS and other forms of dysautonomia occur frequently alongside hEDS — part of the pattern we cover in the trifecta. Fatigue is a core feature of dysautonomia in its own right, so when both are present the effects compound rather than simply coexist.

Chronic pain itself

Persistent pain is metabolically and cognitively expensive. Managing it, working around it, and simply experiencing it all draw on the same limited reserves.

The boom-and-bust cycle

Good days invite catching up on everything missed, which produces a crash, which produces a longer recovery, which produces a bigger backlog. It's the single most common pattern people describe, and the one pacing exists to interrupt.

✅ What tends to actually help

• Targeted strengthening, done properly. Counterintuitively, better-conditioned stabilising muscles do this job more efficiently — but the programme has to be built for hypermobility, which is why an hEDS-literate physical therapist matters so much. Generic strengthening can make things worse.

• Reducing the stabilisation load where you can. Supported seating, a chair with real back support, a footrest, a phone stand instead of a raised arm — every position where something external holds you up is energy your muscles get back.

• Pacing as a baseline, not a punishment. Finding your sustainable level and staying under it, rather than repeatedly discovering your ceiling the hard way.

• Getting the overlaps assessed. If dysautonomia or sleep disruption is contributing, treating those directly changes the fatigue picture in a way that managing hEDS alone won't.

• Ruling out the treatable. Fatigue has many causes, and having hEDS doesn't exempt you from anaemia, thyroid problems or nutritional deficiencies. Ask for the standard workup rather than assuming every symptom belongs to the diagnosis you already have.
