Which disease can vitamin B12 deficiency be attributed to?
Diabetes
Obesity
Alcoholism
Hypertension
The Correct Answer is C
Vitamin B12 is a water-soluble vitamin that is involved in the production of red blood cells, DNA synthesis, and nerve function. Vitamin B12 deficiency can cause anemia, neurological problems, and cognitive impairment. Vitamin B12 deficiency can be attributed to alcoholism because alcohol interferes with the absorption and metabolism of vitamin B12 in the stomach and liver. Alcohol also damages the lining of the intestines, where vitamin B12 is absorbed from food sources.
