The JellieBend
for Core Support & EDS

Important — Read First

The JellieBend is HSA/FSA eligible — save your receipt. Sizing matters: measure your natural waist (the narrowest point above your navel), not your hip or clothing size. If you are between sizes, size up for comfort with prolonged wear. Patients with hypermobile EDS benefit from a gradual wear-in protocol — start with 1–2 hours daily before progressing. Ask your provider if you have respiratory concerns. Abdominal compression alone does not address the full circulatory needs of POTS — lower body compression is equally important and is covered in Section 8.

Section 1

Your core is not just a set of muscles you train at the gym. It is a pressurized canister — a biomechanical system that generates spinal stability, supports organ position, moves blood, and controls pelvic function. When this system loses integrity, the effects ripple across nearly every system in the body.

The intra-abdominal pressure (IAP) canister is formed by four walls: the diaphragm (ceiling — descends on inhalation, compressing the canister), the pelvic floor (floor — levator ani, coccygeus), the transversus abdominis (front and sides — the deepest abdominal layer), and the multifidus and thoracolumbar fascia (back wall). When all four co-contract properly, the canister stiffens — bracing the lumbar spine, holding organs in position, and generating the pressure needed for healthy circulation and movement. This happens automatically before every voluntary limb movement in healthy individuals — a process called anticipatory postural adjustment.

In hypermobile Ehlers-Danlos syndrome (hEDS) and related connective tissue disorders, the canister system is compromised at multiple levels simultaneously. Our Fascial Mapping® assessment regularly reveals the full extent of these failures in EDS patients.

Why the IAP canister fails in EDS

Linea alba laxity. The collagen band connecting the two halves of the rectus abdominis stretches excessively, widening the gap (diastasis recti) and reducing anterior wall tension.

Pelvic floor hypermobility. Lax pelvic floor ligaments impair the muscular seal at the canister base, reducing the ability to generate and hold IAP.

TrA recruitment deficit. Research shows delayed and reduced transversus abdominis activation in hypermobility — the automatic bracing response is impaired even before movement begins.

Diaphragm dysfunction. Ribcage hypermobility and thoracic instability disrupt diaphragm mechanics, altering the pressure dynamics that normally rise with inhalation.

Thoracolumbar fascia laxity. The posterior wall of the canister loses tensile stiffness, reducing force closure that stabilizes the lumbar spine. Gentle, consistent external abdominal compression acts as an external canister wall, partially restoring missing pressure from the outside in.

Section 2

One of the most disabling features of dysautonomia in EDS is splanchnic pooling — the accumulation of blood in the large-capacitance vessels of the abdomen when IAP is insufficient to support venous return. The splanchnic circulation (gut, liver, spleen) can hold up to 25–30% of total blood volume. When abdominal tone is low, blood gravitationally pools there on standing, reducing venous return to the right heart and precipitating postural orthostatic tachycardia syndrome (POTS).

Our Hypermobility & EDS Clinic routinely addresses dysautonomia as part of a comprehensive EDS management strategy. Abdominal compression is one of the best-evidenced non-pharmacologic interventions for POTS, endorsed in the 2015 Heart Rhythm Society Expert Consensus Statement. Equally important is lower body compression — which addresses venous pooling in the legs and is covered in Section 8.

How abdominal compression supports circulation

Reduces splanchnic capacitance. External compression physically reduces the volume available for venous pooling, mechanically displacing blood toward the thorax.

Augments venous return. Higher IAP transmits pressure to the inferior vena cava, improving the gradient that drives blood back to the right heart.

Reduces orthostatic heart rate rise. Clinical studies show abdominal compression reduces the compensatory tachycardia that defines POTS on standing.

Blunts postprandial POTS. The postprandial period (1–3 hours after eating) is particularly problematic in EDS as splanchnic blood flow increases for digestion; compression partially offsets this pooling.

Supports IV hydration and oral hydration therapy by improving the circulatory dynamics that allow volume loading to be effective throughout the day.

The JellieBend is designed for anytime wear — gentle, non-restrictive compression that can be worn during meals, upright activity, and rest. Unlike rigid binders, its spandex construction allows the diaphragm to move freely, supporting circulation without compromising breathing mechanics.

Section 3

Gastrointestinal dysfunction is among the most prevalent and least-discussed comorbidities in EDS. Studies show that over 60% of hEDS patients report significant GI symptoms — early satiety, bloating, gastroparesis (delayed gastric emptying), constipation, nausea, and postprandial symptoms that overlap profoundly with POTS. Multiple mechanisms converge in EDS to disrupt GI motility:

Section 4

Bladder dysfunction in EDS is often attributed to pelvic floor hypermobility and ligamentous laxity — but the deeper mechanism is IAP dysregulation. The bladder sits within the pelvic floor hammock, a sling of fascial and muscular support whose integrity depends on both pelvic floor tone and the intra-abdominal pressure environment above it.

When IAP is chronically low and abdominal wall tone is insufficient, several bladder-related problems emerge — each made worse by the same underlying connective tissue failure:

Section 5

The lumbar spine has no inherent stability without muscular and fascial support. Research by Stuart McGill has shown that the lumbar vertebrae become unstable under as little as 90 newtons of compression without muscular co-contraction — roughly the weight of a large book. In EDS, this instability is compounded at multiple levels simultaneously.

The JellieBend provides circumferential compression around the abdomen and lower thorax — acting as an external TrA, increasing the effective stiffness of the anterior canister wall. This mechanical support reduces the muscular demand on an already-fatigued system, lowering pain levels and allowing patients to engage in upright activity for longer periods. For patients working through Hypermobility Focused Rehabilitation (HFR) at our clinic, abdominal support can be an important adjunct to building the intrinsic core stability that reduces long-term dependence on external compression.

How EDS undermines postural stability

Thoracolumbar fascia hypermobility. The posterior canister wall loses its ability to tension and transfer load, reducing spinal stiffness under compression and increasing segmental shear forces.

Delayed TrA activation. The deep abdominal brace that should fire milliseconds before limb movement is late and weak — the spine moves before it is protected, repeatedly microloading vulnerable structures.

Multifidus inhibition. Pain and instability trigger multifidus atrophy through arthrogenic inhibition — a cycle of weakness and further instability that worsens with each exacerbation.

Proprioceptive deficit. EDS impairs mechanoreceptor signaling in joint capsules and fascia — the nervous system receives poor feedback about spinal position, impairing postural corrections before errors become painful.

Section 6

Not all abdominal support is created equal — and in EDS, the wrong type can worsen symptoms. Rigid abdominal binders and postoperative girdles create high, fixed compression that can restrict diaphragmatic excursion, impair lymphatic flow, and trigger sensory overload in patients with heightened mechanosensitivity.

Section 7

Patients with EDS often experience sensory sensitivity to new compression garments. A graduated wear-in protocol allows the nervous system to adapt and helps you identify the right wearing pattern for your symptoms. Measure your waist at the narrowest point above your navel: XS 22–25″ | S 26–29″ | M 30–33″ | L 34–37″ | XL 38–41″ | XXL 42–46″ | XXXL 50–54″. When in doubt, size up.

Week 1 — 1–2 hours daily

Wear during meals and upright activity. Note any changes in symptoms — bloating, dizziness, energy after eating. If you experience any shortness of breath or rib pressure, remove immediately and reassess sizing before continuing.

Week 2 — 3–4 hours daily

Include the postprandial period (1–2 hours after each meal) as a priority wearing window — this is when splanchnic pooling and GI symptoms are most active. Note whether standing tolerance and energy after meals improve.

Week 3 — 5–6 hours daily

Extend to multiple activity contexts. Begin identifying your highest-benefit wearing times — many patients find the transition between sitting and standing, grocery shopping, and extended upright activity most valuable. Pair with lower body compression (Section 8) for synergistic circulatory support.

Week 4 and beyond — establish your pattern

Most patients find 6–10 hours per day covers their highest-demand periods. Remove at night unless specifically advised otherwise. The goal is purposeful wear during your most symptomatic periods — not passive all-day use.

Ongoing — reassess with your EDS specialist

Abdominal compression works best alongside core rehabilitation — not as a permanent substitute for it. Our Hypermobility & EDS Clinic coordinates abdominal support with HFR and, when indicated, Prolotherapy to the abdominal wall and pelvic attachments to rebuild the internal pressure system over time.

Section 8

Abdominal compression alone addresses only part of the venous pooling problem in POTS and EDS. The lower extremities — specifically the veins of the calves, thighs, and pelvis — are the other major reservoir of orthostatic blood pooling. In EDS, connective tissue laxity allows the venous walls themselves to distend more than normal, increasing the volume that pools in the legs on standing.

The combination of abdominal compression + lower body compression is the most effective non-pharmacologic strategy for POTS management — recommended in Heart Rhythm Society and Vanderbilt Autonomic Dysfunction Center guidelines. The two work synergistically: abdominal compression prevents splanchnic pooling; lower body compression prevents peripheral pooling; together they maximize venous return and reduce orthostatic heart rate rise far more effectively than either alone.

Beyond POTS, lower body compression supports joint stability at the knees, ankles, and hips — all of which are hypermobile and frequently symptomatic in EDS. Graduated compression reduces the muscular demand needed to stabilize these joints during ambulation and reduces the micro-subluxation events that accumulate into daily pain. It also reduces the lower extremity edema that develops from POTS-related circulatory stasis — edema that worsens proprioception and increases fall risk.

For EDS patients, therapeutic compression leggings or pants — worn daily from rising to retiring — are not a luxury. They are part of the baseline management toolkit. The following options are used and recommended by our clinic:

Clinical Perspective

“When I evaluate EDS patients with POTS, GI dysfunction, and lumbar instability, I am often treating what appears to be three separate problems — but which frequently share a single root: a failed intra-abdominal pressure system. The canister that should be quietly managing spinal load, venous return, organ position, and pelvic floor mechanics is, in many of my patients, not generating adequate pressure.”

“External compression is not a cure — it is a scaffold. It buys time and functional capacity while the deeper work of rehabilitation and tissue stabilization proceeds. For some patients, Prolotherapy to the abdominal wall ligaments and pelvic attachments is part of rebuilding the internal pressure system — but that is a longer-term strategy. In the meantime, a well-fitted, comfortable garment worn consistently does measurable good.”

“I also want to emphasize: abdominal compression alone is not enough for most EDS-POTS patients. The lower body is equally important — and many patients experience their best functional days when they combine both. That is why I recommend a full-body compression strategy rather than treating these garments as separate interventions.”
