The purpose of this research study is to assess whether morning bright light therapy using a wearable glasses device called a Re-Timer could potentially improve Irritable Bowel Syndrome (IBS) symptoms and decrease intestinal permeability (leaky gut). Morning bright therapy will be administrated through a safe-wearable device called a Re-Timer. The Re-Timer glasses are lightweight and deliver blue-green light at 500nm, mimicking exposure to natural light.

In this study, we will recruit cirrhotic patients who are undergoing endocscopic procedures as part of their standard of care. Their endoscopies will reveal whether they have portal hypertensive gastropathy. After the procedure, we will ask the patients to provide us with a stool sample, which we will assess for occult GI bleeding. For those patients who DO NOT have occult GI bleeding, they will be contacted every 6 months for 2 years to check whether they have developed GI bleeding.

It is well understood that gastroesophageal reflux disease (GERD) is a serious health condition.1 GERD, which often manifests as heartburn or regurgitation, is a chronic disorder associated with substantial morbidity and has a major adverse impact on patients quality of life.2, 3 Currently, there are limited options for GERD patients seeking a surgical option to treat their disease. One option for anti-reflux surgery is the LINX® Reflux Management System.4 The RETHINK REFLUX Registry (Research to further inform thinking about the role of LINX for Reflux Disease) will monitor long-term outcomes in the areas of safety, effectiveness, health economics and healthcare utilization over 10 years post-LINX surgery.
