You can learn a lot about a person by their fingernails, especially when it comes to health. Anomalies such as changes in shape and color can indicate medical conditions such as psoriasis, heart disease, and even cancer. But keep in mind that brittle or discolored nails are not typically a cause for alarm since they can come from injuries, dampness, poor nutrition, or age.
“For the general population, nail health is most often an indicator of poor nutritional intake or poor digestion,” explains Dr. Sara Norris, a naturopathic doctor based in Los Angeles. “Brittle, weak, and peeling nails are the most common concerns I see in my practice and these symptoms are more often the result of a poor diet than of systemic disease.”
So don’t panic if your nails resemble these descriptions. But if the issue doesn’t resolve on its own or if it accompanies other symptoms (like fatigue, weakness, swelling, heart palpitations, weight loss, etc.) speak to a medical practitioner.
Beau’s lines
Beau’s lines are deep grooved lines that run from side to side on the fingernail or the toenail.They may look like indentations or ridges in the nail plate. May be caused by a lack of Zinc / Calcium.
“Deep lines or grooves across your fingernails are known as Beau’s lines,” says Dr. Bhavini Shah of Lloyds Pharmacy Online Doctor. These lines appear when nail growth has briefly slowed or stopped. “This temporary disturbance of nail growth is usually caused by severe illness or infection. Some people developed Beau’s lines after they had COVID-19, for example.” In severe cases, the nail can stop growing long enough to form a full gap, which is medically known as onychomadesis. This can occur after major stresses like chemotherapy, injuries, and high fevers.
