As you begin the SCD, you may notice significant and obvious changes one day and maybe not so much the next. This sort of up and down over a long period of time can make it difficult to determine your progress. I suppose it’s sort of like being a passenger in the back of the bus with dirty windows and trying to guess how fast the bus is going.
In addition to keeping a detailed food and symptoms log you may find the Crohn’s Disease Activity Index (CDAI) a useful tool when employed at regular intervals. Even though it is not as objective as a colonoscopy it is certainly far more practical in practice and gives you a number that you can easily chart.
From Wikipedia’s page on CDAI:
Remission of Crohn’s disease is defined as a CDAI of less than 150. Severe disease was defined as a value of greater than 450. Most major research studies on medications in Crohn’s disease define response as a fall of the CDAI of greater than 70 points.
