Endometriosis Tracker

Understand your endometriosis
through data

Endometriosis affects 1 in 10 women, yet most people with it spend years without answers. tr8ck can't diagnose or cure endometriosis — but it can help you understand your personal symptom patterns, identify lifestyle triggers, and give you real data to bring to your doctor.

Why endometriosis symptoms
vary so much — and how to track them

Endometriosis is a whole-body condition, not just a period problem. Pain, fatigue, digestive symptoms, and mood all fluctuate with your cycle — and are modified by lifestyle factors that are entirely trackable.

🩸

Cycle-phase dependent pain

Pain is typically worst at menstruation (days 1–3) when prostaglandins peak, and often rises in the late luteal phase. The follicular phase is usually the lowest-pain window. Mapping your pain against cycle phase over 2–3 months reveals your personal pattern — which may differ significantly from the textbook.

😴

Sleep and pain amplification

Poor sleep lowers the pain threshold through reduced endorphin production and elevated inflammatory cytokines. For endometriosis patients, this creates a cycle: pain disrupts sleep, poor sleep amplifies pain the next day. Tracking both together reveals whether sleep is independently worsening your pain.

🔥

Inflammation from diet

Endometriosis lesions are driven by oestrogen and inflammation. A pro-inflammatory diet (high in processed foods, trans fats, red meat) can worsen symptom severity. An anti-inflammatory dietary pattern (omega-3s, vegetables, fibre) often produces measurable symptom reduction over 2–3 months.

🧠

Mood and central sensitisation

Chronic pain conditions involve central sensitisation — the nervous system becomes more sensitive to pain signals over time. Mood, stress, and anxiety directly amplify this sensitisation. Tracking mood alongside pain can reveal whether psychological state is independently influencing pain perception on a given day.

💪

Exercise as a pain management tool

Gentle exercise reduces prostaglandin-driven inflammation and releases endorphins that raise the pain threshold. But intense exercise during a flare often backfires. Tracking exercise type and intensity alongside next-day pain scores helps identify your optimal exercise protocol for different cycle phases.

💊

Hormonal treatment response

If you're on hormonal treatment (the pill, Mirena IUD, Orilissa), tracking pain and symptoms over time helps objectively assess how well your treatment is working — and whether additional lifestyle factors are amplifying or reducing symptoms beyond what treatment alone achieves.

What to log every day
when you have endometriosis

These five data points, tracked consistently across 2–3 menstrual cycles, give tr8ck's AI enough signal to find meaningful patterns in your endometriosis symptoms.

🌙

Cycle dates and symptoms — the anchor point

Log your period start and end dates in tr8ck's cycle module. This allows the AI to phase all other data relative to your cycle — revealing whether pain, sleep, mood, and energy follow a cyclical pattern. Without cycle anchoring, patterns in your other data are much harder to interpret. See also our cycle syncing guide.

🩺

Pain rating — daily, with location note

Rate your pain 0–10 each day using tr8ck's mood/symptom module. If possible, note location (pelvic, lower back, digestive). Consistent daily rating — even on zero-pain days — is essential for the AI to detect the cycle-phase correlation and identify which other factors modify your pain on a given day. The zero-pain days are as informative as the high-pain days.

😴

Sleep quality — pain and sleep are bidirectionally linked

Track sleep quality nightly in tr8ck's sleep module. The AI can determine whether poor sleep independently predicts worse next-day pain scores — separate from cycle phase effects. For many people with endometriosis, sleep quality is the most modifiable factor influencing day-to-day symptom severity.

💪

Exercise — type and intensity on pain days matters

Log every session: type (yoga, walking, swimming, running, strength), duration, and intensity. The AI can identify whether gentle exercise on moderate-pain days improves next-day pain versus resting, and whether intense exercise during certain cycle phases predicts worse pain the following day. Many people discover a personal exercise protocol that significantly reduces chronic endometriosis pain.

🥗

Nutrition — anti-inflammatory pattern over time

Track nutrition quality daily. An anti-inflammatory pattern (more omega-3s, vegetables, fibre; less processed food and red meat) requires weeks of consistency to show symptom benefits. tr8ck's AI can correlate sustained periods of high nutrition quality scores with reduced symptom severity across cycles — showing you whether dietary changes are making a real long-term difference.

What tr8ck reveals across
your endometriosis data

After 2–3 tracked cycles, tr8ck's AI surfaces patterns that are specific to your body — not general endo statistics.

📅

"Your pain scores cluster predictably in cycle days 25–3"

By phasing your daily pain ratings against your cycle data, tr8ck can identify your personal high-risk window — which may be different from the typical pattern. Knowing this lets you plan ahead: lighter exercise, better sleep prioritisation, and anti-inflammatory eating in the days before your predictable flare window.

😴

"Sleep under 6.5 hours predicts 2 points higher pain score next day"

When tr8ck detects that sleep quality independently predicts next-day pain severity — separate from cycle phase — it gives you a direct, actionable lever. Improving sleep during high-risk cycle phases may be one of the most impactful things you can do to reduce endometriosis pain burden.

🧘

"Yoga and walking correlate with lower pain 24 hours later"

tr8ck may detect that gentle movement — specifically yoga or walking — on moderate-pain days is associated with improved next-day pain scores compared to rest days. This kind of granular exercise-pain correlation requires tracking exercise type specifically, not just "did I exercise today."

Common questions

Endometriosis tracking FAQ

Honest, evidence-based answers about tracking endometriosis symptoms with lifestyle data.

How to track endometriosis symptoms?

Log cycle dates, daily pain ratings, sleep quality, mood, exercise type and intensity, and nutrition quality in tr8ck. Over 2–3 cycles, tr8ck identifies whether pain clusters at specific cycle phases and whether lifestyle factors like sleep or exercise type affect next-day pain. See also our chronic pain tracker. Last updated: April 2026

Does exercise help endometriosis?

Gentle movement (yoga, walking, swimming) reduces inflammation and releases endorphins that raise the pain threshold. Intense exercise during acute flares often worsens pain. Tracking exercise type against next-day pain in tr8ck reveals your personal threshold — see the exercise module. Last updated: April 2026

What diet reduces endometriosis symptoms?

An anti-inflammatory dietary pattern — more omega-3s, vegetables, and fibre; less processed food and red meat — consistently shows symptom benefit in research. Benefits typically appear after 2–3 months of consistent change. tr8ck's nutrition quality module tracks this pattern alongside symptom ratings. Last updated: April 2026

How does the menstrual cycle affect endometriosis pain?

Pain is typically worst during menstruation (days 1–3) and rises in the late luteal phase as oestrogen increases. Tracking cycle dates alongside pain ratings in tr8ck's cycle module across 2–3 cycles maps your personal pattern, which may differ from the textbook description. Last updated: April 2026

What is the best app for endometriosis tracking?

For dedicated symptom logging, Phendo is purpose-built for endometriosis research. tr8ck's value is connecting symptoms to lifestyle factors — sleep, exercise, nutrition — across cycles. Many people use both. See also our PCOS tracker if you have both conditions. Last updated: April 2026
