The exact cause of IBD is unknown. It may be contributed by an inappropriate immune response among genetically susceptible individuals resulting in chronic inflammation of the digestive tract. It is believed that the combination of environmental and genetic factors triggers the body’s immune system to react and to produce an inflammatory response in the digestive tract.

Environmental factors

Lifestyle and diet choices may contribute to the development of IBD, such as tobacco smoking, the presence of certain bacteria in the gut and excessive consumption of sugar, saturated fat and processed food.

Genetic factors
