1. Pale or White Nails
May be linked to anemia, liver problems, or nutritional deficiencies.
Healthy nails usually have a soft pink tone from blood flow underneath.
If accompanied by fatigue, dizziness, or shortness of breath, seek medical advice.
2. Yellow Nails
Often caused by fungal infections, especially if nails become thick or brittle.
Persistent yellowing may also be connected to respiratory conditions, thyroid disease, or diabetes.
If color doesn’t improve with basic care, consult a doctor.
3. Blue or Purple Tint
Can indicate low oxygen levels in the blood.
Sometimes associated with heart or lung conditions.
If paired with shortness of breath, chest discomfort, or fatigue, seek prompt medical attention.
