I get diarrhoea a lot, I've had bowel surgery twice second time to remove scar tissue everything ok, diarrhoea started does it mean adhesions back?

May not be adhesions. Without knowing all the issues regarding your intestine it may not be the adhesions. We need more of a background of understanding why you're having these type of symptoms what was the original work up. What was the reason for surgery, and what did your gastroenterologist say.. I would advise you discuss this with your gastroenterologist .
