Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose general abdominal pain only after meals, we could:

  • Research the topic
  • Find a doctor with the time
  • Use a diagnostic computer system.
The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "general abdominal pain only after meals" as a symptom.  Here are eight of many possibilities (more below):
  • Ulcerative Colitis
  • Lactose Intolerance
  • Overconsumption
  • Crohn's Disease
  • Gastritis
  • Mesenteric Ischemia
  • Gluten Sensitivity
  • Stomach Ulcers

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
flatulence
difficulty gaining weight
significant amounts of occult blood
frequent unexplained vomiting
abdominal pain reduced by eating
moderate abdominal pain
having watery stools
significant abdominal distension
diabetes in family members
meals worsen right iliac pain
mild right iliac discomfort
recent onset vomiting
... and more than 90 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of general abdominal pain only after meals:
Cause Probability Status
Gluten Sensitivity 92% Confirm
Overconsumption 26% Unlikely
Mesenteric Ischemia 24% Unlikely
Ulcerative Colitis 3% Ruled out
Crohn's Disease 2% Ruled out
Lactose Intolerance 0% Ruled out
Gastritis 0% Ruled out
Stomach Ulcers 0% Ruled out
* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

If you indicate abdominal pain caused by eating, The Analyst™ will ask further questions including this one:
Do you regularly experience general abdominal pain that begins roughly 20 minutes to 3 hours after eating a meal?
Possible responses:
→ No / I have it even when I don't eat / don't know
→ No, only rarely / a few times a year or less
→ Yes, it started less than 1 week ago
→ Yes, it started about 1 to 4 weeks ago
→ Yes, I've had it for 1 month or more
Based on your response to this question, which may indicate infrequent meal-induced pain, meal-induced pain for under a week, meal-induced pain for 1-4 weeks or meal-induced pain for over a month, The Analyst™ will consider possibilities such as:
Atrophic Gastritis

In cases of chronic gastritis, pain usually appears almost immediately after a meal, especially if the food is coarse or sour.

Gallbladder Disease

Inflammation or other dysfunction of the gallbladder (cholecystitis) or biliary tract (angiocholitis) often causes pain in the abdomen, generally towards the right-hand side.  The pain is more likely to occur after large and/or fatty/oily/fried meals.

Gastric/Peptic/Duodenal Ulcers

Stomach ulcers normally cause pain within 1-1½ hours of eating a meal; duodenal ulcers usually result in pain that starts 1½-2 hours after a meal.

Gastritis

If symptoms come on suddenly and severely, it is classed as acute gastritis.  If it has lasted a long time (usually because of bacterial infection), it is chronic gastritis.

Mesenteric Ischemia

Because total blood flow to the intestine can vary from 25% when fasting to 35% after eating, symptoms are more prevalent after eating.
