Hypothyroidism: What to watch for and what helps

Feeling tired, cold, or gaining weight without a clear reason? Those are common signs of an underactive thyroid (hypothyroidism). This page collects clear, practical articles about symptoms, testing, medication dosing, and small lifestyle changes that actually help people feel better.

Common symptoms and tests

Hypothyroidism shows up differently for everyone. Look for persistent fatigue, feeling cold, slow thinking, dry skin, hair loss, constipation, and unexplained weight gain. Women may notice heavier periods. If these sound familiar, ask your doctor for a TSH test. TSH is the first test doctors use; a high TSH usually means your thyroid is underactive. Free T4 and sometimes free T3 help confirm the picture.

Timing matters: if you just changed thyroid meds, most clinicians wait 6–8 weeks before rechecking TSH. That window lets the body reach a steady state so the lab result reflects the new dose. Pregnant people and those with heart disease often need more frequent checks.

Treatment basics and medication tips

Most people take levothyroxine (brands include Synthroid and generic levothyroxine). Take it on an empty stomach—30 to 60 minutes before breakfast or at bedtime at least 3 hours after your last meal. Why? Food, calcium, iron, and some supplements lower how well your body absorbs the pill.

Common mistakes: taking thyroid medicine with calcium supplements or coffee, switching brands without telling your provider, and skipping follow-up labs. If you notice new symptoms after a dose change—racing heart, sweating, or anxiety—tell your doctor. Those can be signs of overtreatment.

Dose changes aren’t guesswork. Doctors adjust doses based on TSH, symptoms, weight, age, and other meds. For many adults, small changes are made and labs rechecked after 6–8 weeks. Older adults or people with heart disease might start at lower doses and increase slowly.

Beyond pills: simple habits help. Keep a consistent routine for taking your medicine. Keep a list of all your drugs and supplements so your pharmacist can flag interactions. If you’re pregnant, planning pregnancy, or breastfeeding, mention your thyroid—requirements often change.
