It's important to note that dermatological signs alone may not be sufficient to diagnose nutritional deficiencies accurately. Many of these symptoms can also be caused by other medical conditions. If you suspect you have a nutritional deficiency or notice any persistent skin issues, it's essential to consult your GP or a healthcare professional for proper evaluation and diagnosis. They can conduct tests to identify the underlying cause and provide appropriate treatment and dietary recommendations.
