Hangnails/agnails can have various causes, ranging in severity from 'worrying' to 'needs attention'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose hangnails/agnails, we could:
|Increased Folic Acid Need||30%||Unlikely|
|Protein Deficiency||2%||Ruled out|
|Vitamin C Need||1%||Ruled out|
Do you suffer from hangnails/agnails (torn skin around the fingernails or toenails)? If there is a physical cause such as biting, picking, cutting or regular exposure to water/soaps/chemicals then select that response.
Possible responses:→ No / don't know
→ Yes, from a known physical cause
→ Occasionally - A few times a year
→ Regularly - A few times a month
→ Frequently - I usually/always have them
Because nails are found at the extremities, they are the last to receive oxygen and nutrients carried in the blood. Therefore, they often show signs of deficiencies sooner than other tissues.
