Deficiency of vitamin B1 leads to

• A. Beriberi
• B. Night blindness
• C. Rickets
• D. Scurvy

Vitamin B1, also known as thiamine, is essential for energy metabolism and nerve function. A deficiency in this vitamin primarily leads to a condition known as:

Beriberi

Beriberi can manifest in two forms: wet and dry. Wet beriberi affects the cardiovascular system, while dry beriberi impacts the nervous system. Symptoms may include weakness, nerve damage, and heart problems.

Other Conditions Explained

• Night Blindness: This condition is associated with a deficiency in vitamin A, not B1.
• Rickets: Caused by a lack of vitamin D, calcium, or phosphate, leading to weak bones.
• Scurvy: Results from insufficient vitamin C, leading to symptoms like bleeding gums and fatigue.

In summary, the correct answer to the question is A. Beriberi, as it is directly linked to a deficiency of vitamin B1.
