Perimenopause Symptoms Checklist: All 40+ Signs to Track

Perimenopause: The transitional phase before menopause during which ovarian hormone production becomes irregular. Perimenopause typically begins in the early-to-mid 40s but can start in the late 30s. It ends with menopause (12 consecutive months without a period).

Vasomotor symptoms: The clinical term for hot flashes and night sweats — caused by the hypothalamus misreading core body temperature as the body adjusts to declining estrogen levels.

The Complete Perimenopause Symptom List

Perimenopause affects every system in the body. Estrogen receptors exist in the brain, bones, cardiovascular system, skin, digestive system, and urinary tract — all of which respond to declining hormone levels.

Vasomotor Symptoms

Hot flashes, night sweats, cold flashes, chills immediately following hot flashes.

Sleep and Fatigue

Insomnia, difficulty staying asleep, waking at 3-4am, unexplained fatigue that sleep does not fix.

Cognitive

Brain fog, difficulty concentrating, memory problems, word retrieval difficulties.

Mood and Mental Health

Anxiety (often new or worsened), depression, mood swings, irritability, loss of motivation.

Reproductive and Urinary

Irregular periods, heavier or lighter periods, spotting between periods, vaginal dryness, low libido, urinary changes (urgency, frequency, recurrent infections).

Musculoskeletal

Joint pain (especially in hands and knees), muscle weakness, reduced exercise tolerance.

Cardiovascular

Heart palpitations (common and usually benign in perimenopause, but always worth discussing with a doctor).

Neurological

Tingling or numbness in hands and feet, electric shock sensations under the skin (often described as a brief intense flash), tinnitus.

Skin, Hair, and Sensory

Hair thinning or loss, dry or itchy skin, dry eyes, changes in body odour.

Digestive

Bloating, nausea, digestive changes — estrogen affects gut motility.

The Symptoms Doctors Rarely Mention

Electric shock sensations, tinnitus, tingling, itching without visible cause, and body odour changes are all documented in clinical literature but are rarely included in standard GP perimenopause assessments. Many women report being told these symptoms are unrelated to hormonal changes — the clinical evidence disagrees.

Why Tracking Matters

A structured symptom log over several weeks gives a doctor far more useful information than a verbal description of how you’ve been feeling. Patterns — which symptoms cluster together, which time of day they occur, how they relate to your cycle — are what help a clinician make decisions about treatment.

Q&A

What are the first signs of perimenopause?

The most common first signs of perimenopause are irregular periods, sleep disruption, and vasomotor symptoms (hot flashes and night sweats). Many women also report mood changes, brain fog, and unexplained fatigue before they notice changes in their cycle. Symptoms can begin 4-10 years before menopause.

Q&A

How many symptoms does perimenopause cause?

Perimenopause is associated with 40+ documented symptoms. The most widely recognised are hot flashes, night sweats, and irregular periods. Less discussed symptoms include electric shock sensations, tinnitus, tingling limbs, changes in body odour, and heart palpitations — all well-documented in clinical literature but rarely mentioned in standard GP appointments.

Q&A

Can perimenopause cause anxiety and depression?

Yes. Fluctuating estrogen levels affect serotonin and other neurotransmitters that regulate mood. Women in perimenopause are at significantly higher risk of experiencing anxiety and depression than in other life stages. Research from Harvard Health estimates that women in perimenopause are twice as likely to experience depressive symptoms as pre-menopausal women.

At what age do perimenopause symptoms start?

Most women begin experiencing perimenopause symptoms in their early-to-mid 40s, but symptoms can begin as early as the mid-30s. Early-onset perimenopause (before age 40) affects approximately 1 in 100 women.

How long do perimenopause symptoms last?

Perimenopause typically lasts 4-8 years, though it can last up to 10 years. Symptoms often intensify in the final 1-2 years before menopause and may continue for several years after.

Which perimenopause symptoms are least talked about?

Electric shock sensations (a brief intense flash felt under the skin), tinnitus (ringing in the ears), formication (itching or tingling with no visible cause), and changes in body odour are all documented perimenopause symptoms that are rarely discussed in standard medical appointments.
