Deficiency Diseases and Disorders

Scurvy is caused by deficiency of vitamin C (ascorbic acid). Vitamin C is essential for collagen synthesis in the body. Vitamin A deficiency causes night blindness, Vitamin B deficiency causes beriberi/pellagra, and Vitamin D deficiency causes rickets.

Vitamin B1 is chemically known as thiamine. Beriberi is indeed caused by thiamine (vitamin B1) deficiency. L-ascorbic acid is vitamin C, cobalamin is vitamin B12. This is a basic biochemistry/nutrition question testing vitamin names and their deficiency diseases.

Vitamin D deficiency causes rickets, a condition where bones become soft and weak, especially in growing children. Colour blindness is genetic, wickets is a cricket term unrelated to nutrition, and nausea is a symptom not a deficiency syndrome.

Vitamin B12 deficiency causes megaloblastic anemia, where the body produces abnormally large red blood cells that can't function properly. Paralysis is not a direct result, spoon shaped nails indicate iron deficiency, and malaria is an infectious disease.

Vitamin A deficiency causes night blindness (difficulty seeing in low light conditions) and can lead to complete blindness if untreated. Colour blindness is a genetic condition, short sightedness is a refractive error, and myophia is not a recognized medical term.

Niacin (Vitamin B3) deficiency causes Pellagra, a disease characterized by diarrhea, dementia, and dermatitis. Rickets is caused by Vitamin D deficiency, while blindness can result from Vitamin A deficiency. Niacin is essential for energy metabolism and DNA repair.

Iron deficiency causes Anemia, a condition where the body lacks sufficient healthy red blood cells to carry adequate oxygen. Pneumonia, Malaria, and Dengue are infectious diseases not caused by nutritional deficiencies. Iron is crucial for hemoglobin production.

Vitamin C deficiency causes Scurvy, characterized by bleeding gums, joint pain, and fatigue. Oliguria is reduced urine output, Hepatitis is liver inflammation, and Rickets is caused by Vitamin D deficiency. Vitamin C is essential for collagen synthesis.

Arthritis primarily affects the joints, which are the connections where bones meet. It causes inflammation, pain, and stiffness in these areas. The condition specifically targets joint tissues, not bones, lungs, or brain directly.

Cheilosis, characterized by cracks and inflammation at the corners of the mouth (angular stomatitis), is a classic sign of Vitamin B2 (riboflavin) deficiency. This condition is one of the most common manifestations of B-complex vitamin deficiencies.

Scurvy is caused by Vitamin C (ascorbic acid) deficiency. Without adequate Vitamin C, the body cannot synthesize collagen properly, leading to bleeding gums, poor wound healing, and characteristic skin lesions. This was historically common among sailors on long voyages.

Rickets is caused by Vitamin D deficiency, which leads to impaired calcium and phosphorus absorption. Without adequate Vitamin D, bones cannot mineralize properly, causing soft and deformed bones, particularly in growing children. The condition can be prevented with adequate sunlight exposure.
