Pernicious Anemia

I used to be a vegetarian, actually closer to vegan, before I found out I had Pernicious Anemia (PA). I still cook ovo/pesco-vegetarian from time to time. Lately, I've been eating a lot of lean meats, like chicken and turkey. They are good for you. But today, I noticed that I feel extra-fatigued and was craving a hamburger. Craving red meat isn't normal for me. So, that's when I knew the PA was kicking in.
Instead of my vegetable soup for lunch, I had a roast beef hoagie at WaWa. I felt a bit better. But I didn't have red meat for dinner and I am craving it again. I take a liquid B12 supplement, but I've missed a few days because of the holidays - I have to get back on track! Usually the mix of meat and supplements are enough, but I've been missing both.
Basically, PA is an autoimmune disease that prevents vitamin B12 from being properly absorbed by the body. It is not just a B12 deficiency. Many people with PA have some type of digestive issue - like gastroparesis, gerd, colitis, gastritis, ulcerative colitis, crohn's, and celiac. People with IBS only are usually not affected by this problem. Basically, what happens is that because of these conditions, the body can't digest B12 properly (malabsorption) because they are lacking the cells to do so. Also, some medicines used to treat stomach conditions can cause a problem, such as nexium and prilosec for gerd.
B12 is a water-soluable vitamin. It's not something the body makes or stores for long periods of time. It needs to be replenished. B12 is found is large amounts in red meat and liver. It is also found in eggs, but eggs also contain a compound that stops B12 digestion. Other B12 rich foods include clams, trout, salmon, and diary products.
There are many signs of B12 deficiency - fatigue, weakness, constipation, loss of appetite, soreness, confusion, and depression. Because these symptoms are not specific and can be related to many illnesses, it is hard to diagnose. Most of the time, people find out they have it when checking for other medical issues. I found out when I was in the hospital for cysts on my liver and kidneys. It showed in my bloodwork. I was given constant injections to build my levels back up. Blood tests can show PC, but they are not always correct. A person with PC can have normal or even high levels of B12 and will still have PC.
The National Institutes of Health have a really good webpage on B12 and PC -
