Experiencing strong pain in the abdomen is not normal... we can't be sure about the reason you are experiencing this symptom. Certainly, Crohn’s disease can cause abdominal pain. Crohn’s disease is a chronic intestinal autoimmune inflammatory disease with an unknown etiology, or cause. However, you might want to request diagnostic exams to correctly diagnose the symptom before assuming the cause to be Chrohn's. Further, the disease’s severity can vary over time. With medications, Chrohn’s disease can be put under control.
Women with Crohn’s disease can conceive and deliver healthy children. Children do not receive Crohn’s disease directly from their parents. They only inherit the genes responsible for the development of Crohn’s disease. If the child inherits the gene (called NOD2) , however, it doesn’t mean that disease will occur for sure. It is believed that there are also some environmental factors that can provoke Crohn’s disease. Infection with the bacteria Mycobacterium avium paratuberculosis(MAP), for example, one environmental factor that triggers the developments of Crohn’s disease.
Women with active Crohn’s disease should wait to conceive until they are in remission from the disease. They can stop taking medicines for the disease during pregnancy (if Chrohn's is in remission)... but only after consultation with their doctor. If the disease flares-up during pregnancy and a woman is forced to take medicines for Crohn’s disease (corticosteroids and sulphasalasine), there is a very low risk for fetal damage due to medications.
You should consult your doctor before trying to conceive or if you are already pregnant.
