Signs of an underactive thyroid (hypothyroidism)
- Tiredness and low energy
- Weight gain, feeling cold, constipation
- Dry skin, thinning hair, low mood
- Heavier or irregular periods
Signs of an overactive thyroid (hyperthyroidism)
- Weight loss without trying
- Fast or pounding heartbeat, shaky hands
- Feeling anxious, irritable or too hot
- Trouble sleeping
These symptoms are common and can have many causes. A simple blood test tells us whether your thyroid is involved.
How we help
- Blood tests: a TSH test, and further thyroid tests when needed, to find out exactly what's going on.
- Treatment: for an underactive thyroid, a daily thyroid hormone tablet, with the dose adjusted to suit you.
- Regular monitoring: a repeat blood test 6 to 8 weeks after starting or changing your dose, then usually once a year once you're stable.
- Checking for other causes: tiredness and weight changes can also come from anemia, vitamin D or B12 deficiency, diabetes or sleep apnea, and we check for these too.
- Referral when needed: to a thyroid specialist (endocrinologist) for an overactive thyroid, thyroid lumps or other complex problems, and for an ultrasound when needed.
Taking thyroid medicine the right way
Take it at the same time every day, usually first thing in the morning on an empty stomach with water, at least 30 to 60 minutes before breakfast. Calcium, iron and some antacids can block it, so take those at a different time. If you're pregnant or planning a pregnancy, tell us right away, because your dose may need to change.
Frequently asked questions
Will I need thyroid medicine for life?
Most people with an underactive thyroid need treatment long-term, but it's usually one small tablet a day, and most people feel well once the dose is right.
Can thyroid problems cause weight gain?
An underactive thyroid can cause some weight gain and make losing weight harder. Once it's treated, many people find their weight easier to manage. If you're also working on your weight, see our weight loss care.
