I Have A Regular Stool Every Morning. Half The Time

I have a regular stool every morning. Half the time it is normal. The rest of the time, days in a row for
maybe 6 - I might have 1 mormal, then two more before noon that are slightly formed - very loose; or
no form and mushy. Most of the time they will come with explosive gas. I have kept a diary and it seems there is no rhyme or reason I can identify with what I eat. I avoid gassy vegetables like brussel sprouts, and lima beans. With other beans (Once a week) or blackeyed peas, I take a Beano tablet. Sometimes I think its the concentrated orange juice? I eat a fiber diet of about 25 grams a day. I am 5ft
1, and weigh 105 pounds.
