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.

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):

Candida / Yeast
Diabetes II
Gluten Sensitivity
Hypothyroidism
A Sedentary Lifestyle
Anemia
Hypoglycemia
Parasite Infection

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:

taking naps

high air pollution exposure

high cigarette smoke sensitivity

intolerance of sugars

slight abdominal distension

hypothyroidism

missing outer third of eyebrows

having asthma

moderate unexplained weight gain

brittle fingernails

having excess body fat

history of dysentery

... 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
Hypothyroidism	90%	Confirm
Diabetes II	26%	Unlikely
Parasite Infection	17%	Unlikely
Candida / Yeast	4%	Ruled out
Anemia	1%	Ruled out
A Sedentary Lifestyle	1%	Ruled out
Gluten Sensitivity	0%	Ruled out
Hypoglycemia	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:

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:

Allergy to Foods (Hidden)

Anemia

Diabetes Type II

Gluten Sensitivity / Celiac Disease

Hydrochloric Acid Deficiency

Hypoglycemia

Hypothyroidism

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.
