After bariatric surgery, you're likely well aware that with a decreased stomach size, your ability to consume as much food as before is significantly reduced.
The obvious benefit, and likely the reason for your decision to undergo the procedure, is substantial weight loss. However, it's essential to also consider what you may lose with decreased food consumption, including key nutrients like vitamin B12. This is especially important given the changes in your stomach's size and function, particularly if part of it has been removed.
B12 is a critical vitamin for maintaining nerve and blood cell health, and it helps prevent a specific form of anemia that can leave people feeling tired and weak. In today’s blog, we’ll explore why monitoring your B12 intake is especially crucial for bariatric patients.
Why is B12 Intake So Important?
B12 deficiency is relatively common in patients after bariatric surgery. According to Laparoscopic.md, patients who undergo gastric bypass surgery bypass the portion of the stomach that produces intrinsic factor. This also occurs, though to a lesser extent, in patients who have the gastric sleeve procedure.
Intrinsic factor is a protein secreted by the stomach that binds with B12, allowing it to be absorbed after it passes through the mucus membranes in the mouth during eating. Since the portion of your stomach that produces this secretion is no longer stimulated after surgery, your body will absorb far less B12, putting you at risk of deficiency (Laparoscopic.md).
Side Effects of B12 Deficiency
One of the most common side effects of B12 deficiency is anemia, a blood disorder. According to WebMD, symptoms of anemia include fatigue, loss of energy, an unusually rapid heartbeat, shortness of breath, headaches during exercise, difficulty concentrating, dizziness, pale skin, leg cramps, and insomnia (WebMD).
B12 deficiency can also impair the immune system. B12 plays a role in the production of white blood cells, which are crucial for defending the body against infection and illness. Following surgery, when your body is more susceptible to illness and infection, it's vital to ensure your immune system is functioning properly (NIH).
How to Maintain Proper B12 Levels
To manage your B12 levels effectively, consider these strategies:
1. Eat B12-Rich Foods
Certain foods are naturally high in B12, such as seafood like trout, tuna, sardines, salmon, scallops, and clams. Beef, especially organ meats like liver and kidneys, are also excellent sources. Additionally, fortified yeast, milk, and cereals can provide a significant amount of B12 (Harvard Health).
2. Take a Quality B12 Supplement
In addition to consuming B12-rich foods, it’s important to take a reliable B12 supplement, especially after bariatric surgery. Vita4Life!
