A vitamin B12
deficiency is fairly common and easily treatable. Without prompt treatment, however, it can lead to serious problems, including permanent nerve damage. Some of the possible signs of a vitamin B12
deficiency include weight loss and loss of appetite, poor memory, weakness, and constipation
. People who are at an increased risk for developing such deficiencies include elderly adults, strict vegetarians, and people who have had surgery to remove parts of the digestive tract.
