Hypothyroidism Basics
Hypothyroidism basics cover slow metabolism from low thyroid output—fatigue, cold sensitivity, and brain fog need clinician labs and treatment, not harder training alone.
Hypothyroidism basics: an underactive thyroid slows metabolism—fatigue, cold intolerance, constipation, dry skin, and brain fog are common. Causes include Hashimoto's, prior treatment, iodine imbalance, and some medications.
Treatment is clinician-led, often levothyroxine, plus sleep and sane training load—not extreme deficits.
Common questions
-
Can hypothyroidism cause weight gain without overeating?
Yes—fluid, slower metabolism, and lower spontaneous activity can shift weight. Fix the thyroid with medical care; crash dieting usually backfires on energy and training.
