Feeling tired, cold, or struggling with weight despite eating right? Your thyroid could be involved. Thyroid problems are common and treatable if you know what to check and what steps to take next. This page collects clear, practical advice so you can get smarter about symptoms, tests, meds, and safe lifestyle moves.
First step: get tested. Ask your doctor for TSH and free T4; if results are unclear, request free T3 and thyroid peroxidase (TPO) antibodies. TSH is the best starting point — high TSH usually points to underactive thyroid (hypothyroidism), low TSH suggests overactive thyroid (hyperthyroidism). Testing helps guide medication choices and how often you need follow-up.
Levothyroxine (brand name Synthroid) is the standard treatment for hypothyroidism. Take it first thing in the morning on an empty stomach and wait 30–60 minutes before eating or taking calcium or iron — those block absorption. If you still feel unwell on levothyroxine, talk to your doctor about dose checks, timing, or trying combination therapy (T4 plus T3) or desiccated thyroid. Our article "Natural Alternatives to Synthroid" reviews options clinicians discuss in 2025 and what to ask your endocrinologist.
For hyperthyroidism, treatment ranges from antithyroid drugs to radioactive iodine or surgery, depending on severity and your goals. Each option has trade-offs, so weigh symptom relief, long-term risks, and fertility or pregnancy plans with your provider.
Your diet won't cure thyroid disease, but a few nutrients help the gland work properly. Iodine, selenium, iron, and vitamin D play roles—check levels before supplementing. Avoid taking thyroid pills with calcium, iron, soy, or high-fiber meals. If you smoke or use certain herbal supplements, mention that to your doctor; they can interfere with tests and treatments.
Sleep, stress control, and consistent exercise help symptoms like fatigue and weight changes. Small, steady changes in diet and routine beat extreme detoxes. Keep a symptom log to spot patterns and to share with your clinician at visits.
When to push for specialist care: new or worsening symptoms, pregnancy plans, abnormal antibody tests, or when routine treatment doesn't fix how you feel. If labs are oddly discordant with symptoms, ask for a referral to an endocrinologist — they can run nuanced tests and tailor therapy better than a one-size-fits-all approach.
Use this page as a starting point. Read in-depth pieces on our site for medication guides, alternatives, and safe ways to buy prescriptions. If you’re adjusting treatment, get labs 6–12 weeks after a dose change and keep notes on energy, mood, weight, and temperature sensitivity. Small, measured steps move the needle more than guesswork.
Quick checklist: get TSH and free T4, record symptoms for two weeks, take levothyroxine on an empty stomach, avoid supplements at dosing time, talk to your doctor about antibodies and pregnancy planning, consider an endocrinology referral if symptoms persist despite normal labs.
Keep copies of your lab results and share them at every visit. Stay proactive. Always
