Gastrointestinal symptoms in postural tachycardia syndrome: a systematic review, 2018, Shibao et al

Andy · Mar 18, 2018

Abstract

Gastrointestinal symptoms are among the most common complaints in patients with postural tachycardia syndrome (POTS). In some cases, they dominate the clinical presentation and cause substantial disabilities, including significant weight loss and malnutrition, that require the use of invasive treatment to support caloric intake. Multiple cross-sectional studies have reported a high prevalence of gastrointestinal symptoms in POTS patients with connective tissue diseases, such as Ehlers–Danlos, hypermobile type, and in patients with evidence of autonomic neuropathy.

Previous studies that evaluated gastric motility in these patients reported a wide range of abnormalities, particularly delayed gastric emptying. The pathophysiology of gastrointestinal symptoms in POTS is likely multifactorial and probably depends on the co-morbid conditions. In patients with POTS and Ehlers–Danlos syndromes, structural and functional abnormalities in the gastrointestinal connective tissue may play a significant role, whereas in neuropathic POTS, the gastrointestinal tract motility and gut hormonal secretion may be directly impaired due to localized autonomic denervation. In patients with normal gastrointestinal motility but persistent gastrointestinal symptoms, gastrointestinal functional disorders should be considered.

We performed a systematic review of the literature related to POTS and gastrointestinal symptoms have proposed possible mechanisms and discussed diagnosis and treatment approaches for delayed gastric emptying, the most common gastrointestinal abnormality reported in patients with POTS.

Looks as though it might be of interest to you, @Ryan31337...

Thanks @Sasha.

Pretty good round-up though still lacking detail on rapid gastric emptying, which I find bizarre given that they acknowledge it as being significantly more common than gastroparesis. Hanging around POTS/MCAS/EDS forums I often see well identified gastroparesis, but an awful lot more potential rapid gastric emptying that goes unidentified. It can be really crippling but seemingly simpler to 'workaround' than gastroparesis so its a real shame more doctors aren't aware.
