Common Causes of Stomach Pain and Gas

Indigestion

Indigestion can cause abdominal discomfort, fullness, belching, and gas, especially after large or heavy meals.

Constipation

When stool backs up, gas can build and the abdomen can feel painful, bloated, and uncomfortable.

Food Intolerance

Some foods are harder for certain people to digest and may cause gas, cramping, bloating, and pain.

IBS

Irritable bowel syndrome can cause abdominal pain, gas, bloating, diarrhea, constipation, or some combination of these symptoms.

When Symptoms May Be More Serious

Bowel Obstruction or More Severe Abdominal Problems

Severe pain, vomiting, abdominal swelling, or inability to pass stool or gas needs urgent evaluation.

Inflammation or Infection

Fever, worsening pain, or blood in the stool may point toward a condition that needs medical care.

What You Can Try

If symptoms are mild and no red flags are present, it may help to:

• eat smaller meals
• walk gently
• drink enough fluids
• review whether constipation may be involved
• avoid obvious trigger foods

Bottom Line

Stomach pain and gas are often caused by indigestion, constipation, food intolerance, or IBS. But severe, persistent, or worsening symptoms should be evaluated by a medical professional.
