Hi. So, stomach cramps are basically cramping of the stomach or cramping of the digestive track. And basically what that is is acute muscle contractions. Because remember, the digestive track is one, long, muscular tube. So any time you have abnormal contractions, you can develop a cramp. Just like you get a cramp in your leg. So, basically what's happening is there's some altercations within the motion of your digestive tract that causes an abnormal contraction of that portion of the digestive track. So that pain, what you're feeling, is basically an abnormal muscle contraction. And that can be related to an illness, or it can be related to constipation or diarrhea or some sort of abnormality in the motion of your digestive tract.
