Our fingernails always give us some clues about our overall health.
Many things can appear in the nails that can signify systemic or skin problems.
Take notice to anything on or around your fingernails or toenails that suddenly appears different. Anything that doesn’t look normal should be addressed.
Fingernails and toenails are closely related to hair. Just as your hair may fall out after a disease or being under stress, your nails can also show symptoms. Most often, stress can cause appearing lines from side to side on your nails.
2. Moles or melanoma
Dermatologists often hear complains about the nail color. Discolorations generally appear in lines from cuticle to tip, and they can be benign moles or cancerous melanomas.
Consult a dermatologist if the skin under the nail plate gets brown coloring. The concern gets bigger if the coloring affects only a single finger instead of all. Brown lines appearing into the cuticle could be a sign of melanoma. Those lines that stop at or before the cuticle are likely caused by moles.
Arthritis may cause small cysts that grow near or on the cuticles. These small cysts are benign and best addressed by a hand surgeon.
This skin condition can also impact fingernails and toenails. Consult your dermatologist if you have yellow-red discoloring on your nails. These are some other symptoms that can indicate psoriasis:
- Cuts or pits on the nail plate.
- Lines across the nail.
- Thickening of the skin under the nail, which can remove the nail from the nail bed. It usually starts at the tip of the nail and follows toward the cuticle.
- Distinct white spots on the nails.
- Black lines from tip to cuticle are potential symptoms of psoriasis.
- The areas near the cuticle are usually pale, but when they turn red, it could could be caused by congested capillaries, another possible sign of psoriasis.
5. Kidney disease
There are several nail changes that can indicate acute or chronic kidney disease.
- Beau’s lines:These side-to-side lines can be a symptom of acute kidney disease.
- Rough nails with ridges can occur in the presence of kidney disease. Also, these nails are frequently spoon-shaped and concave, pointing to iron-deficiency anemia.
- Dissimilar white lines and spots on nails can point to chronic kidney disease, just like in psoriasis cases.
6. Darier disease
This is a rare genetic disorder that occurs mostly in adolescence. It turns up in the fingernails and toenails as broad, white or reddish lines from cuticle to tip. A V-shaped line near the fingertip can also point to this condition.
Take care for your nails by staying hydrated and consuming a well-balanced diet. Vitamin B and zinc are nutrients that greatly strengthen your nails, so make sure you consume plenty of it.
In many cases, nails changes can be normal and don’t indicate to any undiagnosed health changes. However, the best way is to consult your dermatologist if you think there is something wrong.
