When eating disorders surface in midlife: why this can be a vulnerable time

Eating disorders can occur across the whole of a woman's life, and a growing body of research points to midlife, including the years around perimenopause, as a time when some women become newly vulnerable.

This is not a post about what to do, or how to eat, or how to feel better. It is simply about naming something that too often goes unspoken, so that if it is happening to you, know that you are not alone, and it is worth talking about it with your doctor.

Eating disorders do not have an age limit

In one online study of women aged 50 and above, around one in eight reported at least one current core eating disorder symptom. Among women aged 40 to 60 in another study, roughly one in twenty met the full criteria for an eating disorder, with a similar proportion again experiencing significant symptoms that fell just below the diagnostic threshold.

Binge eating appears to be the most reported pattern at this life stage, more so than the restrictive, very low weight presentations most associated with anorexia. And body dissatisfaction, a core risk factor for disordered eating, is reported by many midlife women.

Eating disorders in midlife tend to follow one of three paths. For some women it is a long-standing illness that has never fully resolved. For others it is the return of something they thought was behind them, sometimes after many years. And for some it appears for the very first time, with no prior history at all.

Why midlife can be a vulnerable time

Fluctuating hormone levels, particularly oestrogen, were historically proposed as the cause of increased eating disorder behaviour, especially binge eating, during perimenopause. It was an appealing idea, drawing a parallel with puberty, another time of significant hormonal change that is well established as a period of heightened risk.

More recent research, however, has questioned whether the hormones themselves are really the driver. Some of this work points instead to the visible changes that come with midlife, such as shifts in body composition and where the body stores fat, which can move a woman further from the narrow cultural ideal of youth and thinness and, in turn, affect how she feels about her body. Weight fluctuation in either direction, or the severity of menopause symptoms themselves, have also been linked to disordered eating in this age group.

On top of the physical, midlife often brings a convergence of life changes that can affect how women see themselves and relate to food. Relationship and role changes such as divorce, an empty nest, or the loss of a parent, alongside relentless messaging from the diet and beauty industries and what researchers call “old talk,” the habit of speaking negatively about one's ageing body, can all add to the pressure.

Midlife appears to be a window of vulnerability for many women, but it is not explained by a single cause. It is better understood as a coming together of physical, hormonal, and life changes.

What matters is not which factor is to blame, but that the vulnerability is real and recognised.

Why it so often goes unnoticed

Even though disordered eating is common in midlife, it frequently slips past everyone, including the women experiencing it. Part of the reason is a kind of ageism that works in two directions. There is the external message that eating disorders are a young person's problem, and there is the internalised version of the same belief, the sense of being too old for this, that can make a woman doubt or dismiss what she is going through. Many women simply do not recognise their own struggles as an eating disorder at all.

Health professionals can miss it too. Midlife women are not routinely asked about eating or body image concerns, and some women who eventually receive treatment report that no clinician ever raised the subject with them. Layered over all of this is shame, stigma, and a tendency to suffer in private.

Why this matters

Eating disorders are serious at any age. There is evidence that the physical toll can be more pronounced in midlife, when the body has less reserve to draw on and other health conditions may already be present. In one study comparing people in treatment, the majority of midlife women across the different eating disorders reported at least one co-occurring medical condition, at notably higher rates than younger people with the same illnesses. That is not a reason for alarm, but it is a reason not to wait, and not to carry it alone.

You are not alone, and it is worth speaking up

If any of this resonates, whether it is a long-held struggle, something resurfacing, or something new and unfamiliar, please consider raising it with your GP. You do not need to have it all figured out, and you do not need to meet any threshold to deserve support. Your GP can talk it through with you and connect you with the right help, which may include an appropriately trained dietitian, psychologist, or other practitioner.

You can also reach out directly to the Butterfly Foundation National Helpline on 1800 33 4673 (1800 ED HOPE), open 8am to midnight AEST/AEDT, seven days a week, for free and confidential support, information, and referral. It is staffed by counsellors with specialist training in eating disorders and body image. (Please note it is not a crisis line. In an emergency call 000, or Lifeline on 13 11 14.)

The most important message is this. Eating disorders in midlife are more common than most people realise, the difficulty you may be feeling is real and recognised, and help exists. Naming it is the first step, and you do not have to take it on your own.

This article draws on two reviews published in the journal Maturitas: Baker and Runfola (2016), who proposed perimenopause as a possible window of vulnerability for eating disorders, and Williams and colleagues (2024), a broader review of body image and eating issues in midlife. The reasons why midlife may carry increased risk, including the role of hormones, are an area of active research rather than settled science.
