The Enneagram and Physical Health: How Personality Affects Your Well-Being

I wrote an article recently for a journal about how our Enneagram type affects our relationship to food. As I researched that topic, I came across a surprising bit of information that reminded me of another important topic: how our type impacts our physical health.

The information was specific to my type, so I’ll use myself as an example to illustrate my point. But I’ll include a few other examples as well to back up the overall premise. I should make a disclaimer, too: Nothing I write here is intended as medical advice. If you have health concerns, seek out a qualified healthcare professional (holistic/integrative if possible, I say).

The root of an Enneagram Seven’s fatigue

I’ve had some mysterious, intermittent fatigue issue for almost 40 years. One doctor said it was mono; another noted that my Epstein-Barr viral load was high. Still another, when I called for an appointment to discuss my fatigue, told me to come in with a negative pregnancy test. (I fired him.)

After working with a naturopath for years, and an acupuncturist occasionally, I still had no answers and no relief. So, I found an integrative M.D. and we began a systematic process of experimenting and multiple tests to get to the root of the problem.

What we discovered is that I have a condition called HPA (hypothalamus–pituitary–adrenal) axis dysfunction. In short, it means the process that regulates energy and resilience doesn’t work right. There can be several causes: “Prolonged stress is a significant factor, encompassing psychological pressures from work, relationships, or trauma, as well as physical stressors like chronic illness, pain, or insufficient sleep.”

I don’t have any significant psychological pressures. But here’s the thing: the bit of information I came across while researching the food article was that Sevens are prone to adrenal fatigue. Why? How do energetic, happy-go-lucky people end up exhausted and nearly bed-ridden?

The effects of chronic low-grade stress

As I thought about this issue, it occurred to me that as an Enneagram 7, I am a Fear Type, which means that I’ve had an undercurrent of low-level anxiety running through me for my whole life. That has to take a toll. For 7s, our strategy is to avoid pain and fear by staying busy, positive and stimulated. Outwardly, Sevens are cheerful, energetic, forward-looking. Inwardly, there is typically a subtle hum of restlessness or “I can’t sit with this discomfort” syndrome.

This can mean that even if a 7 feels happy and unstressed, their nervous system is still active, scanning for the next thing to keep them safe or distracted. The HPA axis responds not just to conscious stress, but to:

• Underlying vigilance (always being “on”)
• Overstimulation (lots of activity, multitasking, novelty-seeking)
• Suppressed or avoided emotions (which still register physiologically, even if not consciously felt)

For a Type 7, the body can still produce a chronic low-grade stress signal, even if the mind says: “I’m fine, I’m happy.” Over the years, this can tax adrenal output, leading to what’s colloquially called “adrenal fatigue.”

To sum up, here’s why Enneagram Sevens may be prone to adrenal fatigue:

1. Fear Triad wiring – The nervous system defaults to vigilance, even behind the smile.
2. Tendency toward overstimulation – Lots of activity, little rest, frequent “dopamine chasing” (food, experiences, ideas).
3. Avoidance of stillness/pain – Restorative downtime is harder to access, so recovery lags.
4. Optimism masking depletion – By the time fatigue shows up, the stress pattern has been running for a long while.

Looking at this condition through the Enneagram lens, we see that the “fear” of Type 7 is often unconscious, but the body still carries it.

This is yet another reason why understanding your personality type is so important to your overall well-being. If you can spot the underlying tendencies of your type, you have a better chance of making the changes needed to remain in good health.

Other examples

In my research, I found an anecdote about people suffering from ALS. At a well-known clinic, receptionists got to the point that they could tell whether people had a positive ALS diagnosis by interacting with them. They found that ALS patients are amiable and polite. They would say things like, “He’s way too ornery to have ALS” – and they would be right. Amiability is not an Enneagram type, but certain types (Type 2, for instance) tend to naturally possess that trait more than others types.

And fretful Sixes often suffer from stomach issues; my maternal grandfather, another close relative and a friend all fit that observation. It seems that Eights are prone to high blood pressure. I hope that as the Enneagram advances, those in the medical profession will study the relationship between type and its affect on health.

I’d love to hear from you if you have a story similar to mine – one in which you’ve come to understand that the root of a health condition is likely related to your personality. The mind-body connection is more than a slogan; it’s a living, breathing reality that we would all do well to heed. You can reach me at heath@heathdavishavlick.com.
