Hormonal / Endocrine
Cold Intolerance
Feeling unusually cold or unable to warm up — a hallmark symptom of hypothyroidism, low metabolic rate, iron deficiency anemia, or extreme caloric restriction.
Hair Loss
Shedding more hair than normal (>100 hairs/day) or visible thinning — caused by hormonal shifts, nutritional deficiencies, excessive stress, or medication side effects. Different mechanisms require different approaches.
Low Libido
Reduced sexual desire or interest — a common complaint with significant quality-of-life impact. Frequently driven by hormonal imbalances (low testosterone or estrogen), chronic stress, poor sleep, and nutritional deficiencies.
Menstrual Irregularities
Changes in menstrual cycle — skipped periods, irregular timing, heavier/lighter flow, or mid-cycle spotting. Often a stress signal from the body when energy availability is too low or hormonal balance is disrupted.
Night Sweats
Episodes of excessive sweating during sleep — soaking sheets or clothing — that may signal hormonal changes, infection, medication effects, or autonomic dysregulation.
Weight Gain (Unexplained)
Gaining body weight without changes in diet or exercise — often driven by hormonal imbalances (thyroid, insulin, cortisol), medication side effects, fluid retention, or muscle gain masking fat loss.
