Tag: Phrynoderma

Vitamin A deficiency is a significant cause of preventable blindness in children worldwide, but it also has profound effects on the skin, causing a condition known as keratinization. This abnormal hardening of epithelial tissues leads to dry, rough, and scaly skin, a condition known as follicular hyperkeratosis or phrynoderma. Understanding the link between nutrition and this skin issue is crucial for prevention and treatment.

According to extensive medical research, significant nutritional deficiencies, particularly concerning vitamins essential for epithelial tissue health, are strongly linked to skin abnormalities. Answering the question, **which vitamin deficiency causes hyperkeratosis?**, is key to understanding the profound connection between diet and dermatological conditions.

According to the World Health Organization, vitamin A deficiency is a significant public health problem affecting more than half of all countries. While most people associate this deficiency with eye-related issues like night blindness and xerophthalmia, the effects extend far beyond vision, causing various extra ocular manifestations of vitamin A deficiency that impact skin, immunity, and overall development.
