Thyroid problems can sneak up slowly. You might blame tiredness, weight changes, or mood swings on stress — but the thyroid could be the real cause. Get clear on what to watch for, how doctors test for it, and simple steps that help you manage treatment and supplements safely.
Hypothyroidism (underactive thyroid) often shows as fatigue, weight gain, cold sensitivity, dry skin, constipation, and slower thinking. Hair thinning and heavier periods are common too. Hyperthyroidism (overactive thyroid) tends to bring fast heartbeat, anxiety, heat intolerance, weight loss despite eating more, tremor, and loose stools. If a close look at your daily life matches several of these, ask your doctor about thyroid testing.
Tests to request include TSH, free T4, and sometimes free T3. If autoimmune disease is suspected, doctors check anti-TPO antibodies. An ultrasound helps when lumps or swelling appear. Don’t expect a single visit to settle everything: labs and symptoms together guide the next steps.
If you need replacement therapy, levothyroxine is the usual choice. Take it on an empty stomach, ideally 30 to 60 minutes before breakfast, or at bedtime at least four hours after your last meal. Calcium, iron, antacids, and soy can block absorption, so separate these by at least four hours. Your doctor will recheck TSH about six to eight weeks after any dose change.
For hyperthyroidism, treatments range from short-term medicines like methimazole or propylthiouracil, to radioactive iodine or surgery in some cases. Beta-blockers often help with symptoms like fast heart rate and tremor while other treatments take effect. Pregnancy changes the options, so talk to an OB-GYN and endocrinologist if you are pregnant or planning pregnancy.
About supplements: iodine helps only if you are iodine-deficient. Too much iodine can make autoimmune thyroid problems worse. Selenium shows modest benefit in some trials for autoimmune thyroiditis, but talk to your doctor before starting it. Avoid natural desiccated thyroid without medical supervision; doses vary and labs must be watched closely.
Keep a simple routine: track symptoms, keep a single list of all medications and supplements, and get labs done at the same lab when possible for consistent results. If your energy or weight changes suddenly, don’t wait — call your provider. Thyroid care is often straightforward once you find the right dose and follow up.
