One in eight women will develop a thyroid disorder in her lifetime. If you feel tired, cold, or suddenly gaining weight, the thyroid might be the cause. This short guide helps you spot common signs, understand tests, and know treatment options.
The thyroid is a small gland in your neck that controls metabolism by making hormones called T4 and T3. TSH from the pituitary tells the thyroid to work harder or slow down. When production is too low you get hypothyroidism; when it's too high you get hyperthyroidism.
Common hypothyroid symptoms include fatigue, weight gain, cold sensitivity, dry skin, hair loss, and slowed thinking. Hyperthyroid symptoms often show as rapid heartbeat, weight loss, heat sensitivity, anxiety, tremor, and trouble sleeping. Symptoms overlap with other conditions, so testing matters.
If you suspect a problem, start with a TSH blood test. A high TSH usually means underactive thyroid; a low TSH suggests overactive. Doctors may also check free T4 and free T3. For autoimmune causes they order thyroid peroxidase (TPO) or TSH receptor antibodies.
The most common cause of hypothyroidism is Hashimoto's thyroiditis, an autoimmune condition that slowly damages the gland. Graves' disease is the main autoimmune cause of hyperthyroidism and can cause eye symptoms and rapid heart rates.
Treatment is straightforward in many cases. Hypothyroidism is usually treated with levothyroxine, a synthetic T4 pill taken once daily. The dose is adjusted by tracking TSH and symptoms. Hyperthyroidism treatments include antithyroid medications, radioactive iodine, or sometimes surgery, depending on age, cause, and severity.
Take levothyroxine on an empty stomach, 30 to 60 minutes before breakfast, and avoid calcium or iron supplements within four hours. Many drugs and supplements change thyroid labs, so tell your doctor about every medicine you take.
Your lab report matters. Look for TSH first, then free T4 and maybe free T3. If antibodies are checked, TPO or TRAb will guide diagnosis. Keep copies of lab dates and doses so trends are clear.
Diet won't cure thyroid disease, but certain nutrients matter. Iodine is essential but too much can cause problems; most people get enough from food. Selenium may help autoimmune thyroid disorders in some studies, but talk to your doctor before starting supplements. Aim for a balanced diet, regular sleep, and stress control—these help symptoms and energy.
If you're pregnant or planning pregnancy, check thyroid function early. Untreated hypothyroidism can affect fetal brain development. Pregnant women often need a higher levothyroxine dose and closer monitoring.
See a healthcare provider if you have persistent symptoms or irregular periods, fertility issues, swollen neck, or unexplained weight change. A primary care doctor or endocrinologist can run tests and make a treatment plan.
Use this guide to ask better questions at your appointment and keep copies of your thyroid tests; tracking results over time makes management easier.
