Vitamin B12 Deficiency – Symptoms, Causes, Diagnosis, Treatment & Prevention | Cobalamin Deficiency

Vitamin B12 Deficiency – Symptoms, Causes, Diagnosis, Treatment & Prevention | Cobalamin Deficiency Vitamin B12 is essential for nerve function, DNA synthesis, and red blood cell production, with deficiency potentially leading to severe health issues. Common causes of B12 deficiency include a lack of dietary B12 (especially in vegetarians and vegans), malabsorption disorders (like Crohn’s disease or celiac disease), pernicious anemia, age-related absorption decline, certain medications, and alcoholism. Symptoms range from fatigue, anemia, and neurological issues to mouth ulcers and, in rare cases, vision impairment. Diagnosis typically involves blood tests and specific indicators like methylmalonic acid or homocysteine levels. Treatment varies from dietary adjustments and oral supplements to injections or nasal sprays for severe cases. Prevention strategies include a balanced diet with B12-rich foods, supplements for at-risk groups, moderating alcohol intake, and regular screenings for susceptible individuals. #vitaminb12deficiency #vitaminb12deficiencysymptoms #vitaminb12deficiencycauses #vitaminb12deficiencytreatment #vitaminb12 #cobalamindeficiency #cobalamin Join this channel to get access to perks:    / @learnmedicineasap   --------------------------------------------------------------------------------------------------------------------------------------------- Subscribe for more medical and health content:    / @learnmedicineasap   Check out our other helpful playlists Obstetrics and Gynecology    • Obstetrics and Gynecology   General Surgery Lessons    • General Surgery Lessons   Internal Medicine    • Internal Medicine   Child Health and Pediatrics    • Child Health and Pediatrics   Pharmacology Lecture Videos    • Pharmacology Lecture Videos   Anaesthesiology | Anesthesiology    • Anaesthesiology | Anesthesiology   Medical Parasitology    • Medical Parasitology   Infectious Diseases    • Infectious Diseases   Pathology    • Pathology   Microbiology    • Microbiology   Anatomy    • Anatomy   Ear Nose and Throat - ENT    • Ear Nose and Throat - ENT   Oral Health | Oral Hygiene | Dental Health    • Oral Health | Oral Hygiene | Dental H...   Ophthalmology | Eye Infections | Eye Diseases    • Ophthalmology | Eye Infections | Eye ...   Oncology    • Oncology   Sexually Transmitted Disease (STD) | Sexual Wellness & Health - Sexual Infection | STI    • Sexually Transmitted Disease (STD) | ...   Women's Health    • Women's Health   Men's Health    • Men's Health   Vitamins, Minerals and their Deficiencies | Vitamin Deficiencies | Mineral Deficiencies    • Vitamins, Minerals and their Deficien...   Clinical Skills | Clinical Techniques    • Clinical Skills | Clinical Techniques   Pharmacology Mnemonics    • Pharmacology Mnemonics   Internal Medicine Mnemonics    • Internal Medicine Mnemonics
