Causes of Vitamin B12 Deficiency | In-Depth Overview including Medications, Diseases & Fish Tapeworm

Lesson on Vitamin B12 Deficiency Causes, including dietary intake issues, medication use, gastrointestinal disease (ex. crohn’s disease, celiac disease), GI infections, pancreatic disease and autoimmune conditions (ex. pernicious anemia). Vitamin B12 (cobalamin) is essential in our diet as we are not able to synthesize it ourselves, and it is necessary for healthy red blood cell production, DNA synthesis and central nervous system functioning. Vitamin b12 deficiency can be due to a variety of causes within 2 major categories: reduced dietary intake and compromised absorption. Compromised absorption entails a wide variety of causes including certain medications, and issues within the gastrointestinal tract.

In this lesson, we discuss a detailed overview of causes of Vitamin b12 deficiency, including discussing pernicious anemia, crohn’s disease, celiac disease and We also discuss the physiology of normal B12 metabolism and absorption and discuss where in this physiological pathway many disease states interfere with B12 absorption.

Thank you so much for sharing this important informations & also for your precious time.. 🙏

So eating too quickly, not chewing sufficiently, should inhibit, reduce, the amount of saliva taking the one way trip down with the B12 containing food. Logic would dictate that we are off to a bad start for B12 absorption. Thoughts people?

[josephde-zordi]

Good overview, good list of causes of deficiency, the fish tape worm is scarey

[Ad-zknz]

I had all the symptoms of vitamin B12 deficiency except fatigue, all after 18 years of veganism.
I started eating eggs, raw yogurt Kefir, some goat cheese... and soon I will try some chicken. I don't eat this because I want to, but because I have to..

[cornypinkuni]

For me it was genetic. Changed my life.

[dmariewalker]

Lab work back, I’m on the low end of Vitamin B12 deficiency I was told to take an over the counter B12, I’m getting copy of lab work Wednesday.

[Kekes]

I have chrons disease diagnosed in 2008 and had my first b12 shot today. I always feel tired, foggy brain and low energy. Let’s see if it makes a change 🙌🏾

[kdegregorio]

FYI -- very important for future clinicians to understand:


Celiac disease is an autoimmune disease not a GI disease!


thank you!

[mermaid]

Why don’t you talk about the genetic issues with Transcobalamin?

[jackiesicilian]

Can low saliva cause a problem with absorption of b12?

[georgetucker]

Thanks the explanation of how B12 is absorbed. Just found out I have B12 Deficiency. Dr. will start B12 injections.

[Darvelicia]

Hello JJ medicine, you say anything can cause B12 methabolisme and absortion disruption. Also if you have diarea for 4 years with blothing belly? Please dont mind misspelling of words English is not my first language I speek fluently but grammar sucks.

[stephenleighton]

can anyone explain or give clarity on the following ... does any change to typical Purine & Pyrimidine, folate, B6 or B12 pathways during pre or early post natal periods result in heritable genetics that could be passed from that baby should they procreate in later life?

[Prosperity_]

Suggest a good supplement for b13 and b6 combined.

Hello I need help please! I am having issues nerve pain stabbing random pains/muscle spasms. I took spectracell micronutrient test and I am deficient in all these vitamins. I have been targeting these foods highest in these vitamins but I still have this pain all over my body. What should I do? I went to neurologist plus gastro only showed inflammation in digestion system and removed non cancerous tumors. Bloods test came back normal except for liver enzymes alt and creatin kinase slightly elevated. Nerve pains didn’t occur until 1 week after Vacine(Moderna) not sure if any of this related since I had digestion issues prior but this time endoscopy shows inflammation throughout intestines.

[shrutigupta]

Can use of ppis for like 10 days cause b12 deficiney ?

[sajidkhanmahmood]

Amazing i think my mother is suffering from issues of b12 deficiency she has all the symptoms which i dont think i need to go into suffice to say she has had ulcers and also has T2 diabetes so she is taking omeprozole and metformin for the last 5 years. She is in a pretty bad way always tired and in pain with pins and needles in her feet and legs plus always exhausted. The doctors have never suggested anything re B12 deficency and i have been researching myself and after videos like this have come to the decision i should try her with some b12 supplements. My worry is because of her low stomach acid because of ppi use will B12 capsules even work and if so which type of B12 and at which dosage. I hope someone can help me with this i am very worried for her.

[momoary]

Sometimes when I eat meat it feels like I am not digesting it properly. I am suffering slot from either B12 or B6. I feeling very bad. Tired, bloated, dry skin, esp scalp, esp. I feel like there is something above my navel. I feel thirsty, I lost glow on my face and much more..

[timothyburchett]

How about excessive coffee consumption or alcohol consumption? Will that create a deficiency?
