I am a 20 yo female and I have been having gastrointestinal problems for the approximately the past two years. After I eat, approx. 30 min later, I have intense stomach pain, gas, and a diarrhea. I was recently told that when I was a baby, I had to go on special food because the doctor said I was unable to digest proteins. However, from about ages 2 until 18 I did not have any problems. Am I still experiencing an inability to break down proteins?
