FAQs
What do hypothyroidism nails look like?
Hypothyroidism nails are often brittle, thin, and prone to splitting. They may show white vertical ridges, horizontal grooves, or lift from the nail bed.
Can nail changes be an early sign of hypothyroidism?
Yes, nail changes like brittleness or ridges can appear before other symptoms such as fatigue or weight gain, making them an early clue.
What causes nails to lift in hypothyroidism?
Nail lifting (onycholysis) happens due to reduced keratin production and poor circulation, both linked to low thyroid hormone levels.
How long does it take for nails to improve after thyroid treatment?
Nails usually start improving within 3–6 months of stable thyroid hormone levels, but full recovery may take longer.
Are there other skin signs with hypothyroidism?
Yes, dry skin, facial puffiness, and thinning hair or eyebrows often accompany nail changes in hypothyroidism.
