Understanding Vitamin D Deficiency Diseases

This question asks to identify the disease resulting from a lack of Vitamin D.

Role of Vitamin D

• Vitamin D is essential for calcium absorption, which is crucial for strong bones and teeth.
• It also plays a role in immune function and overall health.

Diseases from Vitamin Deficiency

A deficiency in specific vitamins leads to distinct health conditions:

• Vitamin D Deficiency: Primarily causes Rickets in children, characterized by soft, weak, and deformed bones. In adults, it can lead to osteomalacia (bone softening).
• Vitamin A Deficiency: Leads to Night blindness, difficulty seeing in low light conditions, and can progress to total blindness.
• Vitamin C Deficiency: Causes Scurvy, marked by fatigue, gum disease, skin bruising, and poor wound healing.
• Vitamin B1 (Thiamine) Deficiency: Results in Beriberi, affecting the nervous system (wet beriberi) or cardiovascular system (dry beriberi).

Identifying Rickets

Based on the functions and deficiency effects of these vitamins:

• Rickets is directly linked to insufficient Vitamin D.
• Night blindness is linked to Vitamin A.
• Scurvy is linked to Vitamin C.
• Beriberi is linked to Vitamin B1.

Therefore, Rickets is the disease caused by Vitamin D deficiency among the given options.
