you should try to improve the condition, period. whether you are trying some special diet like the SCD diet(specific carbohydrate diet-buy the book), or all the alternatives people talk about on this site. never adopt the attitude to let it be as it is, if you arent trying anything new, you arent learning or progressing. Im not saying this to only scare and frighten you, but to empower you, so you are more in control of your destiny and prepared.
first issue- you arent absorbing as many nutrients as a normal person, this can put you at risk for any other disease imaginable and just make you more prone to infections and sickness. you need b12 supplements and magnesium supplements, and make double sure to get everything else everyday. your ileum is inflamed and this is where magnesium, b12 and all essential fatty acids are absorbed omega 3-6-9, these issues are crucial to just maintaining normal everyday function, beyond treating the disease process itself.
second issue- you could develop an intestinal blockage, at which point, surgery is an absolute neccessity to continue life. because you will be vomiting your food instead of digesting it.
third issue- long term inflammation can lead to things like cancer and blood clots/strokes and heart attacks. so SOMETHING must be done.
fourth issue- scarring can occur, which make the diseased tissue lose functionality.
GOOD NEWS- i have had crohns for 4 years now and have had almost none of the major issues and I have not used medication because im insane. but i have avoided ALMOST every single dangerous obstacle i may have encountered, so it can be done. Thats right, no surgery, very little complications, and this is coming from a severe case, not a light case that is easily treated and controlled with medication. but i am not here to encourage you to avoid medication, im just telling my story so you know that approaching it with other angles can really make a difference, but will not cure you. So DO everything you can to learn how to improve your condition and never stop taking notes and making observations as to what helps or hurts you, or makes you better or worse. And make a full on plan to try some of the medications or take the steps in all those directions.
i have eaten a diet that is high in fiber(refried beans, oatmeal, Wheat(only gold medal whole wheat flour), low in sucrose(refined sugar) and lactose(milk sugar),and low in meat protein, cooked veggies mainly broccoli and cauliflower, and low in fruit as it contains some sucrose. without getting too specific, that is a general explanation for my results. oh and nothing made with yeast like store bought bread. the diet is labor intensive, but will avoid lots of complications.
In 4 years i have never had more then 2 bms a day, and they are never diarhea like, just occasional slight mucus and sometimes constipation. i havent solved every issue yet, but i regret the times i assumed or falsely concluded nothing more could be done, i cant believe im still finding things that improve me to this day, just never ever stop learning and trying.
good luck.
