What causes Crohn’s disease?

The exact cause of Crohn's disease is not known, but it is thought to be a combination of genetic, environmental, and immune-related factors.

Genetics: Studies have shown that Crohn's disease tends to run in families and that certain genetic mutations may increase the risk of developing the disease.

Immune system: People with Crohn's disease have an overactive immune system that mistakenly attacks the cells in the digestive tract, leading to inflammation.

Environmental factors: Certain environmental factors, such as smoking, diet, and stress, may also play a role in the development of Crohn's disease. For example, smoking increases the risk of developing Crohn's disease and can make symptoms worse. Some studies suggest that a diet high in processed foods may increase the risk of developing the disease, while a diet high in fruits and vegetables may decrease the risk.

Infections: Some studies suggest that certain infections may trigger the development of Crohn's disease or cause flare-ups.

It's important to note that the cause of Crohn's disease is multifactorial, and it is not just one single factor that causes the disease.
