Brittle Nails Are One Of Many Thyroid Symptoms
When the thyroid is underactive, the body slows down due to a decrease in thyroid hormones. This causes slow growing, and brittle nails.
Talk to your doctor
The thyroid also controls sweating and less sweat is produced when it is underactive. A natural moisturizer, when sweat is lacking, nails are far more likely to become dry.
If you are experiencing brittle nails, it may be indicative of thyroid symptoms or hypothyroidism. Consult with your doctor and arrange a thyroid test as soon as possible.
