How do you know when your Crohns is playing up?

When I am flaring I will have an increase in symptoms. i.e. More frequent diarrhea, cramps or obstruction symptoms.

I have asked that same question also. I was diagnosed with Crohns in the terminal illeum 3 years ago after a routine colonoscopy. I was alittle shocked. My symptoms are mild with frequent small flare ups. What type of symptoms are you experiencing?

well your question implies that you have not communicated succesfully with your doctor.

if you are referring to your primary physician..you might realize that they are in charge of ordering tests such as blood test. It is your job to be open to dialogue regarding any changes to the results of the tests from previous visit. You should in return initiate the dialogue as to if any changes in the blood test as compare to previous visit has occurred ...however minor. There is a normal range for blood test values. So if there is any trend within the range, then you know before it gets out of the range. For example if something goes down even slightly from before and there is a feeling you get as a result then its certainly possible you feel the way you do as a result of the changed value. For me its potassium and that is a tricky electrolyte because of the serious implications in either of the high or low areas. If you are severely flaring ,chances are, your potassium is out of the normal range. why not keep an eye on it when you feel so-so. I also find that changing it is also difficult as this is not something you can suddenly consume a bunch of bananas and you are better. It is something to watch all the time so you should get blood test every 6 months and this requires you have some idea of how you feel and what the values of your blood are at that time so you can gain some knowledge from the blood test. So if I get so muscle twitch i might drink some gatorade that day instead of some other drink.
