In hypothyroidism, which nail change is commonly observed?

• A. Thick, brittle nails
• B. Long, strong nails
• C. Soft nails
• D. No nail changes

Answer: (A)

In hypothyroidism, reduced thyroid hormone slows many bodily processes, including nail growth and the integrity of the nail plate. The result is nails that are dry, brittle, and prone to cracking or breaking, often with slower growth. This combination—dryness and brittleness—tavors the description of thick, brittle nails, which is a common nail finding in hypothyroid patients.

Long, strong nails would imply robust growth and resilience, which isn’t typical when thyroid function is low. Soft nails aren’t the usual pattern here, since hypothyroidism tends to make nails brittle rather than soft. No nail changes would overlook a well-recognized manifestation of the condition.
