could stress lead to swollen stomach?

Hi Wldflwr,

Abdominal Swelling can be caused by many things, including:
Abdominal swelling, or distention, is more often caused by overeating than by a serious illness. This problem can be caused by:

Air swallowing (a nervous habit)
Buildup of fluid in the abdomen (this can be a sign of a serious medical problem)
Gas in the intestines from eating foods that are high in fiber (such as fruits and vegetables)
Irritable bowel syndrome
Lactose intolerance
Ovarian cyst
Partial bowel blockage
Pregnancy
Premenstrual syndrome (PMS)
Uterine fibroids
Weight gain

Call your health care provider if:

The abdominal swelling is getting worse and does not go away
The swelling occurs with other unexplained symptoms
Your abdomen is tender to the touch
You have a high fever
You have severe diarrhea or bloody stools
You are unable to eat or drink for more than 6 - 8 hours
