Vitamin deficiency (avitaminosis)

Medical records that document your confirmed diagnosis of a vitamin deficiency are the foundation of any rating. For the 10% level, records showing decreased appetite, weight loss, abdominal discomfort, weakness, difficulty concentrating, or irritability support the criteria. For 20%, clinical notes or lab findings confirming stomatitis, achlorhydria, or diarrhea are relevant.

For the 40% level, exam findings or treatment records documenting all three — stomatitis, diarrhea, and symmetrical dermatitis — at the same time help show that threshold is met. For 60%, records that also reflect mental symptoms and reduced bodily vigor are relevant. For 100%, documentation of marked mental changes, moist dermatitis, inability to hold down adequate nourishment, severe exhaustion, and cachexia — often found in hospitalization or specialist records — directly addresses those criteria.

Your own statements, and statements from people who know you, describing how symptoms such as weakness, digestive problems, or skin conditions affect your daily activities and ability to work can also help show the level of severity you experience.
