Appetite changes in menopause: hungrier, or never hungry

Why appetite is hormonally governed

Appetite is regulated by signals reaching the hypothalamus, principally leptin from fat tissue signalling sufficiency, and ghrelin from the stomach signalling hunger.

Oestrogen interacts with this system. It has effects on leptin sensitivity and influences hypothalamic appetite regulation directly, which is part of why appetite varies across the menstrual cycle in a predictable way.

When oestrogen becomes erratic and then falls, that regulation becomes less stable. The direction of the resulting change is not uniform between people.

Increased appetite

The dominant driver is sleep. Restricted sleep raises ghrelin and lowers leptin measurably, and the effect skews preference towards energy-dense food specifically.

The second driver is glucose instability from declining insulin sensitivity: a sharper post-meal rise followed by a sharper dip, and that dip is experienced as hunger.

Stress adds a third: cortisol increases appetite, and the mid-forties supply a reliable stream of it.

Reduced appetite, which gets less attention

Appetite loss is reported less often but matters more when it happens, because its causes are different:

• Depression and anxiety, both of which commonly suppress appetite and both of which rise in perimenopause
• Medication effects, including some antidepressants and treatments for diabetes
• Overactive thyroid, which can cause weight loss despite a normal or increased appetite
• Nausea, which is itself a perimenopausal symptom
• Reflux and early satiety, which become more common in midlife
• Alcohol, which displaces food intake

The symptom that must not be folded in

Persistently feeling full soon after starting to eat, particularly alongside bloating and abdominal discomfort, is a recognised presenting symptom of ovarian cancer.

It is not the same as reduced appetite generally. The distinguishing feature is early satiety — wanting to eat, starting, and being unable to continue — present most days rather than fluctuating.

It warrants prompt assessment, usually a CA125 blood test and a pelvic ultrasound, rather than being absorbed into a menopause explanation.

When to see someone

Book promptly for unintentional weight loss, persistent early satiety, appetite loss lasting more than a few weeks, or difficulty swallowing.

Ask for thyroid function, full blood count, ferritin and HbA1c for appetite change in either direction, and mention mood explicitly, since depression is a frequent and treatable cause that is rarely volunteered in an appetite conversation.
