Deficiencies in vitamin C can lead to which of the following conditions?

Vitamin C deficiency leads to the condition known as scurvy, which is characterized by symptoms such as fatigue, weakness, swollen and bleeding gums, and joint pain. The body requires vitamin C for the synthesis of collagen, an essential protein in connective tissues, skin, and cartilage. Without adequate vitamin C, collagen formation is impaired, leading to the breakdown of these tissues and resulting in the symptoms associated with scurvy.

The other conditions listed are linked to different nutrient deficiencies. For instance, rickets is caused by a deficiency in vitamin D, calcium, or phosphate, leading to weakened bones and skeletal deformities. Beriberi is associated with a lack of thiamine (vitamin B1), affecting the cardiovascular and nervous systems. Pellagra is a result of niacin (vitamin B3) deficiency and is characterized by symptoms such as dermatitis, diarrhea, and dementia. Each of these conditions corresponds to a specific nutrient deficiency, which highlights the unique role vitamin C plays in maintaining overall health.
