What Causes B12 Deficiency?
Vitamin B12 is an essential nutrient that helps to keep the body functioning properly.
It is found in a variety of foods, including meat, fish, dairy products, and some fortified foods. Unfortunately, some people may not get enough vitamin B12 from their diet, leading to a deficiency.
Diet is the most common cause of B12 deficiency. People who do not regularly eat foods that are rich in vitamin B12, such as meat, fish, and dairy products, may not get enough of the nutrient. Vegans and vegetarians are particularly at risk for B12 deficiency, as these diets do not include any animal products. Additionally, people who follow a restrictive diet, such as those with anorexia or bulimia, may also be at risk for B12 deficiency.
In addition to diet, there are several other factors that can contribute to B12 deficiency. Certain medications, such as antacids and proton pump inhibitors, can interfere with the body’s ability to absorb vitamin B12. Gastrointestinal conditions, such as Crohn’s disease and celiac disease, can also lead to B12 deficiency. Finally, older adults may be at an increased risk for B12 deficiency due to a decrease in stomach acid production, which is necessary for the absorption of B12.
If left untreated, B12 deficiency can lead to a variety of health problems, including anemia, nerve damage, and cognitive decline. Therefore, it is important to be aware of the potential causes of B12 deficiency and to take steps to ensure that you are getting enough of the nutrient. Eating a balanced diet that includes animal products, such as meat, fish, and dairy, is the best way to ensure that you are getting enough vitamin B12. Additionally, if you are taking medications that may interfere with B12 absorption, talk to your doctor about other options. Finally, if you have a gastrointestinal condition, be sure to talk to your doctor about how to manage it and get enough B12.
