Always tired? When to have your thyroid checked
Published · 3 min read · Endocrinology

The most common reasons for constant tiredness are poor sleep, stress and anaemia. But in women, especially after childbirth and after 40, an underactive thyroid (hypothyroidism) is a frequent cause too.
Signs to look out for
- Tiredness that doesn’t go away after a night’s sleep.
- Feeling cold when everyone else is warm.
- Putting on weight for no clear reason.
- Hair loss and dry skin.
- Constipation.
- Changes in your periods.
Which test
The first step is a TSH test: it costs 12 ₼ and the result is ready the next day. If TSH is out of range, the endocrinologist orders free T4 and antibodies and, if needed, a thyroid ultrasound.
Treatment for hypothyroidism is usually one tablet a day, with the dose adjusted to your TSH every 6–8 weeks. If you are planning a pregnancy, it is especially worth checking your TSH beforehand.
