When you dont go pee my stomch get big what does that mean?

When you don't go pee, your bladder fills up with urine. This can cause your stomach to appear larger than normal, as the bladder is located in the lower abdomen. Additionally, when the bladder is full, it can press on the intestines, which can also contribute to a bloated appearance. When you urinate, the bladder empties and the stomach should return to its normal size.
