I waited about 7 months to see this dr. and it took 15 minutes. He tells me I don't need a colonoscopy and I have ibs. duh!! He didn't know that magnesium helped with constipation, I told him that I take about 600mg a day and it helps a lot and to maybe mention this to other patients who are constipated. He did a little rectal exam. While I was on the table and he examining me I thought I would tell a little joke because the doctor looked a little uptight, I said " this is just like seeing the vet" he had no reply so I repeated what I said and again no reply. I think this doctor is constipated. I think I informed him more about ibs that him informing me. You huys know way more about this ibs than any specialist. He told me to continue doing exactly what I'm doing. I told him that lactose bothered me, he asked if I had diarrhea when I enjested lactose and I told him I didn't . He says that I'm not lactose intolerant. I do get stomach bloat, pain when I take in lactose, so what the heck could this be? Any suggestions?
