Any relation between ehlers danlos syndrome and gastric telangiectasias?

Ehlers Danlos : This type of EDS is the result of mutations in type III collagen which is abundant in major blood vessels, skin, and hollow viscera. Diagnosis is based on presence of two of the following: thin, translucent skin, arterial/intestinal/uterine rupture,easy bruisability, and facial features.

Yes, but not EDS-HT: Functional bowel disorders such as IBS are more commonly related to EDS-HT. Gastric telangiectasias are probably more likely to be related to vascular EDS than the hypermobility type. Or perhaps completely unrelated in your case. A rheumatologist should be able to sort this out.
