Energy Sinks
Periods of profound depletion where ordinary activities feel overwhelming, energy reserves empty rapidly, and rest doesn't restore the way it once did.

Phase impact
Energy sinks tied to late luteal phase or external factors; shorter duration, more predictable, more responsive to rest than perimenopausal sinks
Sinks appear as counterpoint to swells; dramatic due to contrast but often shorter and less frequent than later phases
More frequent, intense, and unpredictable sinks; may last weeks; significantly impact function; unpredictability creates stress
Persistent, profound sinks as hormones decline consistently; near-constant sink becomes predominant experience for many
Dramatic fluctuations decrease; energy depletion continues but becomes more stable; adjustment to lower baseline ongoing
Energy improves and stabilizes; sinks when they occur more related to external factors than hormonal fluctuation; overall function improves
Hormonally-driven sinks absent; energy stable; aging-related factors may create fatigue requiring ongoing adaptation
Typical vs. concerning
Typical energy sinks involve significant but fluctuating fatigue related to hormonal transition, with some pattern or periodicity, eventual improvement or stabilization, and ability to maintain basic function even if reduced. They're physically uncomfortable but not accompanied by severe pain or alarming symptoms. Concerning presentations include unrelenting exhaustion for months without variation, progressive worsening, complete inability to function or care for self, suicidal thoughts, post-exertional malaise lasting days, accompanying physical symptoms (unexplained weight loss, fever, severe pain, neurological changes), or abnormal lab results suggesting serious medical conditions. The key distinction: typical sinks are hormonally-driven, fluctuate over time, and allow survival-mode functioning, while concerning patterns are unrelenting, progressive, or accompanied by symptoms suggesting serious underlying disease.
When it makes sense to get medical input
Consult a clinician for profound exhaustion lasting weeks without improvement, significant functional impairment affecting work or self-care, complete exercise intolerance, unrefreshing sleep despite adequate duration, heavy bleeding potentially causing anemia, depression or suicidal thoughts, persistent symptoms despite lifestyle interventions, uncertainty about whether this is normal perimenopause, desire to explore medical interventions like hormone therapy, symptoms affecting relationships or employment, age under 40 with perimenopausal symptoms, or energy depletion with concerning accompanying symptoms (unexplained weight changes, persistent pain, neurological symptoms, fever). Bring tracking data and request appropriate testing including complete blood count, metabolic panel, thyroid panel, iron studies, vitamin D and B12 levels. Advocate for thorough evaluation—profound fatigue warrants medical attention, not dismissal as normal aging.
