The symptom score aggregates all your entries, the good and bad ones of one day, and is based on your values for abdominal pain, headache, other pain, mood, stool (constipation and diarrhea), and flatulence. The most severe symptoms (and how often you track them) then determine your symptom score. If several symptoms have the same severity, this also increases the symptom score. The lower the symptom score, the better you should feel. To see your symptom score go to the "Journal" and your weekly / monthly overview.
