Hypothyroidism
Hypothyroidism means the thyroid gland is not making enough thyroid hormone. That hormone sets the pace of much of the body, so when levels run low things slow down. Common signs include tiredness, feeling cold, weight gain, dry skin, constipation, low mood and slower thinking. They build gradually, which is why many people put them down to stress or ageing before a blood test points to the thyroid. It is more common in women and tends to appear in middle age, though it can start at any time.

How hypothyroidism is treated
Treatment replaces the hormone the thyroid is no longer making. The standard option is levothyroxine, a synthetic form of the main thyroid hormone, taken once a day. Some people who do not feel fully well on it alone also use liothyronine, a faster-acting hormone. Doses are matched to your blood results and reviewed over time, so taking the tablet at the same time each day, usually on an empty stomach, helps keep levels steady. You can see the full range on our thyroid health page. Iodine intake matters too, and parts of inland Southeast and South Asia still see iodine-related thyroid problems, so a balanced diet supports treatment rather than replacing it.
