What Causes Drowsiness After Eating?

Drowsiness after eating can have various causes, ranging in severity from 'troubling' to 'generally fatal'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnose your symptoms now!
  • understand what's happening to your body
  • have a doctor review your case (optional)
  • identify any nutritional deficiencies

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose drowsiness after eating, 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 "drowsiness after eating" as a symptom.  Here are eight of many possibilities (more below):
  • A Sedentary Lifestyle
  • Overconsumption
  • Candida / Yeast
  • Anemia
  • Hypothyroidism
  • Lack Of Sleep
  • Stomach Cancer
  • Food Allergies

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:
confirmed heartburn
frequent unexplained sadness/crying
recent onset diarrhea
tetracycline use
occasional sore throats
acute abdominal pain
painful swallowing
pain medication use
meals worsen epigastric pain
bags under eyes
history of frequent dieting
spacey/unreal feelings
... and more than 160 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of drowsiness after eating:
Cause Probability Status
Overconsumption 98% Confirm
Anemia 27% Unlikely
A Sedentary Lifestyle 16% Unlikely
Candida / Yeast 2% Ruled out
Lack Of Sleep 1% Ruled out
Stomach Cancer 0% Ruled out
Hypothyroidism 0% Ruled out
Food Allergies 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.

In the Sleep-Related Symptoms section of the questionnaire, The Analyst™ will ask the following question about drowsiness after meals:
How often do you become very tired within 1-3 hours of eating a meal?
Possible responses:
→ Never / rarely / don't know
→ Once a month or less
→ Once a week or less
→ A few times per week
→ At least daily
Based on your response to this question, which may indicate occasional postprandial somnolence, regular postprandial somnolence or frequent postprandial somnolence, The Analyst™ will consider possibilities such as:
Lack of Sleep

You are more likely to feel sleepy after a meal if you didn't get enough sleep the night before.

Problems Associated With A Sedentary Lifestyle

Exercise can keep you alert during the day and reduce the risk of post-meal tiredness.  Many studies agree that regular exercise helps increase overall energy and reduce fatigue.
