Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The investigators are following the same strategy for investigating an underlying pathophysiology of Chronic Fatigue Syndrome (CFS/ME) in another group of patients. The age- and gender matched control group will be established from the beforementioned control group.
The investigators will also be screening for a peritoneal microbiome (possible correlate for leaky gut) in study patients undergoing abdominal surgery.
We will also investigate changes in fatigue and in lipidome, metabolome, exome and microbiome by double-blinded, placebo-controlled administration of probiotics to the study population.
