Hello,brandtphoen, Most often the occasional abdominal pain after eating or drinking occurs due to contraction in the intestines called Peristalsis . This happens in some more often than others. Cold beverages tend to cause more contractions than hot or warm drinks. Try to chew your food slowly and take the drink after you are done eating. Drinking during the middle of the meal sometimes you swallow more air which can add to the bloating or distension. I am glad that you are trying to get enough fiber in your diet by eating more vegetables and fruits. Keep that up. If your bowel movements are regular then there is less chance for gas getting trapped in the intestine and giving you pain. Wish you good health.
