My Hematologist has written a report to my doctor noting that I have developed mild Pancytopenia and have already started on B12 injections last month.

American Academy of Neurology: People with inflammatory bowel disease may also be at risk for developing nerve damage and other neurological problems, according to research that will be presented at the American Academy of Neurology’s 59th Annual Meeting in Boston, April 28 - May 5, 2007. Inflammatory bowel disease includes digestive disorders such as ulcerative colitis and Crohn’s disease that cause swelling and/or bleeding in the intestines. For the study, researchers compared 103 people with Crohn’s disease and ulcerative colitis to 51 people with other digestive disorders, such as irritable bowel syndrome, gastritis and chronic heartburn. The researchers found that those with inflammatory bowel disease were about four times more likely to develop neuromuscular conditions, including carpal tunnel syndrome and small fiber neuropathy, which causes pain and lack of feeling in the feet. Those with bowel disease were also more than six times more likely to also have a disorder called sensorimotor polyneuropathy, a nerve disease that can cause weakness, pain, and numbness. These diseases were more common in women with bowel disease than men. “Inflammatory bowel disease patients commonly suffer from several other medical conditions, like B12 deficiency and glucose intolerance. These nerve conditions we have reported are often not diagnosed by their primary care physicians,” said lead study author Francisco De Assis Gondim, MD, MSc, PhD, Professor of the Federal University of Ceará in Ceará, Brazil, and a member of the American Academy of Neurology. “People with inflammatory bowel disease who develop new symptoms, such as pain or numbness in the feet, should see a doctor.”

[@MariaReyes-jp4lb]

Exactly, to bad they don’t test here in the states until they’ve caused lots of damage and making tons of $ off of people and insurances. It’s a cheap test and cheap treatment. Unfortunately they recommend we treat our animals for them at least twice a year but not humans even when we are around them on a daily basis. Not including all the other places we can be exposed to them such as restaurants, unwashed fruit ect.. it just doesn’t make sense to me. Thankful we are able to get the treatment for them from a local place that was willing to get us some. One time treatment. One pill then one more 6 weeks later to treat eggs that may have not been rid of. They recommend doing this at least two times a year to be safe.

[@MedicosisPerfectionalis]

There is no such thing as hyperchromatic or hyperchromic anemia...It’s self-contradictory!

[@xDomglmao]

Why would it be self-contradictory? You could have less RBCs (anemia) but the ones present could be very pigmented (I don't know any condition but logically it's possible).

Hello 👋 thank you very very much for your efforts 🌷🌷 But i have two questions one is amylase for carbs digestion ? But u said it help to dissociate B12 from protein ? Is this mean amylase has two functions ??? The other question is normal flora in our intestine also synthesized B12 true ! ? If the person is strict vegan B12 not become zero ?? And don’t reach to severe state ?? Can you clarify this to me ?? And again thank you 😊

[@MedicosisPerfectionalis]

Answer to: Q1: yes, amylase has more than one function. Q2: just because it’s in your gut, doesn’t necessarily mean that you will absorb it in sufficient amounts (i.e. the concept of bioavailability). Instead of looking into theories, look into the statistical scientific studies of patients with B12 deficiency, a huge percentage of them are strict vegans. Hope it helps! Good luck!
