Vitamin B absorption, particularly 𝐵 12 𝐵 1 2 , is blocked by long-term use of acid-reducing medications (PPIs, H2 blockers), metformin, and heavy alcohol consumption. It is also hindered by digestive disorders like Celiac disease, Crohn’s disease, pernicious anemia, gastric bypass surgery, or eating low-nutrient diets.
What Causes Vitamin B Deficiency? Here's a roundup of 4 of the top causes of vitamin B deficiency: a non-balanced diet, excessive alcohol consumption, various medications (such as proton-pump inhibitors, or PPIs), and gut malabsorption conditions.
An increase of one unit in vitamin B12 was associated with a 1.04% decrease in hemorrhoid occurrence. Conclusion: This study suggests that evaluating homocysteine, copper, folate, and vitamin B12 levels may be valuable in patients with or at risk of hemorrhoidal disease.
Lifestyle habits: Drinking too much alcohol can make it harder for your body to absorb vitamin B12. For men this is more than two drinks in a day. For women, it's more than one drink in a day. Medicines: Taking certain medicines can make it harder for your body to absorb vitamin B12 over time.
Dietary sources
One of the primary ways to boost Vitamin B12 absorption is to ensure you are getting an adequate amount of this vitamin in your diet. Vitamin B12 is naturally found in animal-based foods like meat, fish, dairy products, and eggs.
B12 deficiency can trigger specific food cravings, most notably for meat, fish, or eggs, as the body seeks animal-based sources to replenish the vitamin, especially in those on vegetarian/vegan diets or older adults. While cravings for sugary or salty foods can also signal general B-vitamin issues, the distinct urge for protein-rich animal products is a key indicator, but professional testing is crucial for confirmation.
Two common types of GERD medicines have been linked to vitamin B-12 deficiency:
The worst symptoms of B12 deficiency involve severe neurological damage, including severe memory loss, confusion, dementia, psychosis, hallucinations, balance problems, trouble walking, and irreversible nerve damage (neuropathy), alongside serious mental health issues like severe depression or irritability, with physical signs including extreme fatigue, pale skin, and a sore, smooth tongue. These severe cognitive and neurological issues are the most concerning because they can become permanent if left untreated.
Gastroesophageal reflux disease (GERD) and its manifestation as reflux esophagitis (RE) involves mucosal inflammation and autonomic dysfunction. Vitamin D3 deficiency is increasingly implicated in gastrointestinal inflammation and immune imbalance.
Additionally, supplementing vitamin C can support the formation and maintenance of healthy blood vessels, which is very good for hemorrhoid patients. Moreover, vitamin E has anti-inflammatory effects, effectively healing damaged tissues and reducing hemorrhoid clusters.
Neurological changes
Vitamin B12 deficiency due to lack of intrinsic factor causes a type of anemia called pernicious anemia. Among older people, absorption may be inadequate because stomach acidity is decreased. Decreased stomach acidity reduces the body's ability to remove vitamin B12 from the protein in meat.
Even though the B-group vitamins are found in many foods, they are water soluble and are generally quite delicate. They are easily destroyed, particularly by alcohol and cooking.
People need vitamin B-12 for the brain to work well. If not treated, vitamin B-12 deficiency can lead to issues with the nerves, brain or spinal cord. These might include lasting tingling in the hands and feet or trouble with balance.
Cutaneous manifestations associated with vitamin B12 deficiency are skin hyperpigmentation, vitiligo, angular stomatitis, and hair changes. A diagnosis of vitamin B12 deficiency is often overlooked in its early stages because these signs are not specific to vitamin B12 deficiency alone.
One of the reasons for vertigo, which patients describe as a 'feeling of turning', is a lack of vitamins. Yeditepe University Hospitals Otolaryngology and Head and Neck Surgery Specialists, who drew attention to the latest research, said "Iron deficiency anemia, vitamin B12 and D deficiency cause vertigo".
Dry, itchy skin is often a sign of a vitamin D deficiency. As vitamin D is created through skin exposure to the sun and cholesterol in the skin, in the winter months, when sunlight exposure is less, people often experience dry, itchy skin attributing it to the cold weather.
Vitamin B12 itself is vital for energy production, red blood cell formation, and nerve function. Typically, B12 cocktails include a mix of B12 injections or supplements, coconut water, citrus fruits, and other natural ingredients known to aid in weight management.
Conditions affecting the stomach
Some stomach conditions or stomach operations can prevent the absorption of enough vitamin B12. For example, a gastrectomy, a surgical procedure where part of your stomach is removed, increases your risk of developing a vitamin B12 deficiency.
Symptoms such as pins and needles, disturbed vision, a sore and red tongue, mouth ulcers, muscle weakness and problems with balancing and walking, psychological problems such as depression and confusion, problems with memory, understanding and judgement could also be related to B12 deficiency.
Organ meats and shellfish are the richest dietary sources, with a 3-ounce (85 g) serving of cooked clams providing approximately 84.1 µg, while beef liver contains about 70.7 µg. Fatty fish, such as trout and salmon, supply 5.4 µg and 4.8 µg per 3-ounce serving, respectively.
