• Swelling from pancreas
• Abnormal growth of tissue, such as:
  • Scar tissue due to a peptic ulcer
  • A cancer growth

Risk Factors

Things that may raise the risk of this problem are:

• Peptic ulcer disease
• Gastrointestinal tumors
• Pancreatitis

Symptoms

Problems may be:

• Regular, frequent feeling of bloating or fullness
• Feeling full after eating less food
• Nausea and vomiting of undigested food, especially right after eating
• Belly pain or swelling

Diagnosis

You will be asked about your symptoms and health history. A physical exam will be done.

Tests may be done to look for blockages. This can be done with:

• X-rays of the abdomen using a contrast material
• Endoscopy to view the interior of the stomach and intestines

The movement of food through the stomach may also be tested.
