Hot Flashes, Menopause and Gut Flora: The GAPS View

Hot flashes are called “hot flushes” in the GAPS book. Dr. Natasha Campbell-McBride discusses them within her gut-hormone framework, including observations of children, younger women and men as well as women at menopause. The useful question is how that explanation fits the person’s actual life stage and symptoms, rather than assuming one cause from the symptom alone.^[1]

The Gut-Flora Explanation

In Gut and Physiology Syndrome, Campbell-McBride proposes that hormone-like substances and other chemicals produced by an altered microbial community can contribute to hot flushes. She connects this with mood changes, fatigue and other hormonal symptoms in her clinical observations.^[1]

Her examples outside menopause are part of the reason she looks at gut flora. They do not establish that menopause has no role in hot flashes or that the same mechanism has been demonstrated in every child or adult. The endocrine-organ guide explains the broader signaling model.

Menopause in the GAPS Framework

The book treats menopause as a natural life stage and argues for improving gut flora and metabolism to make the transition more comfortable. The official FAQ reports that GAPS has helped some women remove symptoms or make them more bearable.^[1][2]

That range matters: the FAQ includes relief without claiming that every woman becomes symptom-free. I have not reached perimenopause or menopause, so I do not have a firsthand outcome to add. My cycle-care story describes the period changes I have actually experienced.^[2]

Standard HRT and the BHRT Exception

The 2020 book is strongly critical of synthetic hormonal intervention. The official FAQ makes a distinction that should stay visible: Campbell-McBride does not support what she calls drug-based standard HRT, but says bio-identical hormone therapy can be helpful, particularly for severe menopausal symptoms. She specifically mentions progesterone and the need to keep the wider hormone balance in view.^[1][2]

The FAQ also notes that prescriptions may need monitoring and adjustment as symptoms change. Its acknowledgment of benefit should not be erased by shortening the answer to “GAPS says no hormones.”^[2]

“Bioidentical” describes a hormone’s chemical similarity to one made in the body; it does not, by itself, say whether a product is compounded or FDA-approved. FDA-approved products with hormones identical to human hormones exist. The actual product and route matter when discussing treatment.^[3]

The Cancer Reference Needs Its Treatment Context

The book cites the National Cancer Institute when discussing HRT and hormone-sensitive cancers. NCI distinguishes estrogen alone from estrogen-plus-progestin therapy, and separates outcomes by treatment and whether the person has a uterus. Those distinctions matter; the reference does not support one identical cancer-risk statement for every hormone regimen.^[4]

Keep that specific treatment context alongside the book’s criticism. It is more accurate than telling every reader that any hormone prescription causes the same outcome or never helps symptoms.

What the FAQ Says About Reducing BHRT

The reduction advice is for someone already taking BHRT whose health has been improving while following GAPS. Campbell-McBride describes gradual, individual trial and error, with an example of reducing one-tenth of the daily dose about once a week and adjusting the pace to symptoms. Some women stop; others remain on a lower dose longer.^[2]

That is the source’s example in a particular answer, not a taper schedule for every product or prescription. Keep changes in prescribed hormones with the prescriber. Your own symptom observations are an important part of that discussion.

Vaginal Dryness and Libido: A Separate FAQ Answer

Question 9 concerns a 59-year-old woman, six months into Intro, with vaginal dryness and reduced libido who did not want hormone therapy. Campbell-McBride mentions homemade kefir and sour cream as lubricants and, for food, fatty duck or goose and organ meats. This is the actual case context of that short answer, rather than a treatment formula established for every reader.^[2]

Keep dryness, pain, discharge, bleeding and libido changes distinct when describing what is happening. A food or topical suggestion in an FAQ does not establish the cause of all those different symptoms.

A Useful Record for the Next Conversation

Note when the episodes happen, how they affect sleep, current treatment and recent changes. Use the endocrine guide for the wider GAPS explanation and the food guidance for your phase. An unusual symptom outside menopause still deserves its own assessment rather than a default label.

For the broader cycle and life-stage topic, this is the companion in my catalog. GAPS Cycle Care: From First Period to Menopause is listed in my course catalog.
