Thanks for reaching out. I hope our community shares their personal experiences with you. Also, be sure to speak with your doctor about any new, changing or concerning symptoms, if you haven't already. Do you notice a pattern of when you feel dizzy? Is it correlated to having a bowel movement or perhaps to not eating for a few hours? Could it be related to dehydration? In addition to speaking with your doctor, this article may be helpful to you: https://irritablebowelsyndrome.net/living/dehydrated.
