https://betterlifegenie.com/Hypothyroidismzn
Hypothyroidism means your thyroid gland (butterfly-shaped, front of neck) makes too little T4/T3 hormone, so every cell slows down. Auto-immune destruction (Hashimoto’s) causes ~95 % of adult cases in iodine-sufficient countries; other triggers include surgical removal, radiation, iodine deficiency, or certain drugs (lithium, amiodarone). The result: fatigue, weight gain, cold intolerance, dry skin, constipation, slowed heart rate, depressed mood, and “brain fog.” Because symptoms creep in gradually, >50 % of sufferers remain undiagnosed; a simple TSH blood test (plus free T4) is the screening gate—TSH >4.0 mIU/L usually confirms primary Hypothyroidism
