Vitamin B1 deficiency causes which disease?

Vitamin B1 deficiency causes which disease?

• A. Pellagra
• B. Beriberi
• C. Rickets
• D. Scurvy

Answer: (B)

Thiamin (vitamin B1) is essential for energy metabolism and nerve function. When it’s deficient, beriberi can develop. There are two main forms: dry beriberi, which causes weakness and peripheral neuropathy with muscle wasting, and wet beriberi, which features cardiovascular problems like edema and heart failure. In severe cases, impaired carbohydrate metabolism can lead to lactic acidosis and more systemic symptoms. Other vitamin deficiencies cause different diseases: pellagra from niacin deficiency presents with dermatitis, diarrhea, and dementia; rickets from vitamin D deficiency affects bone mineralization; scurvy from vitamin C deficiency leads to gum disease and poor wound healing.
