Most people who have their gall bladder removed have no side effects at all, other than some discomfort from the surgery.
It is usual to have pain in the incisions and in the right shoulder for about three days after surgery; the shoulder pain is caused by irritation of the diaphragm by gas, this irritation causes “referred pain” which is experienced as shoulder pain. After the initial pain has settled, there is usually some mild discomfort in the incisions for two to three weeks.
Pain can sometimes continue after surgery. Severe attacks of pain are uncommon; they can be caused by spasm of the bile duct, by stones or scarring affecting the bile duct, or by unrelated conditions that can mimic gallstone pain.
About 15% of people find oily or fatty foods disagree with them, causing bloating or diarrhoea. This is usually mild, but can vary depending on the foods eaten. Younger people are at a slightly higher risk: http://onlinelibrary.wiley.com/doi/10.1111/j.1445-2197.2007.04119_30.x/abstract
