Aging
Thyroid imbalance
Vitamin deficiencies (especially biotin or iron)

Iron-deficiency anemia
Heart disease
Autoimmune conditions

7️⃣ Horizontal Ridges (Beau’s Lines)
Deep ridges across the nail may appear after:
Severe illness
High fever
Major stress
Uncontrolled diabetes

🚨 When to See a Doctor
You should consult a healthcare professional if:
The change is sudden and unexplained
It affects multiple nails
It comes with fatigue, weight loss, or pain
The nail separates from the nail bed
🌿 Important Reminder
Nail changes don’t always mean something serious. Many are caused by aging, cosmetic products, or minor injuries.
But your body often gives subtle clues before bigger symptoms appear.
Pay attention — without panic.
