GP suggested I ask gastroenterologist, on 2nd visit, about pancreatic insufficiency, but never got the chance because she had already decided that I have IBS instead.
Anyway, here's what I found later on one website:
EPI (Exocrine Pancreatic Insufficiency): pancreas unable to produce the enzymes needed to aid digestion.
Symptoms: hunger, diarrhoea, loss of nutrients, loss of weight, vitamin deficiencies- incl. B12* very commonly, often leading to SIBO.
*B12: can impair mental functions, drastically decrease energy levels, digestion issues, weight loss.
EPI: enzyme replacement in food throughout life
B12 deficiency: Injections necessary: oral supplement does not appear to be effective as inability to absorb nutrients
How did I find this useful information? By Googling "PETS with B12 deficiency."
......(no mention at all of IBS ! )
Think my GP has once again proved that she knows more than any of the consultants she has sent me to. Maybe her husband is a vet ?
Think this calls for a cartoon, beginner1
