Welcome to the gastroenterology community! What laxatives were you taking? You are probably bloating because you are constipated.
Actually I am no longer constipated and having regular bowel movements. Since I quit the laxatives (senna and casgara) 3 weeks ago, I have been taking psyllium husks in capsules which has really help with my constipation and made me regular and able to have a bowel movement every day.
However, I am very bloated. According to information on the web bloating is a side effect of laxative withdrawal. I don't exactly know why and trying to find out. I explained my situation to health food stores and they suggested maybe taking probiotics and even digestive enzymes.
How long were you taking the laxatives?
