Study Notes
Causes of Vitamin and Mineral Deficiency
- Poor diet: Lack of essential nutrients in the diet, such as a diet that is high in processed foods and low in fruits and vegetables
- Malabsorption: Body's inability to absorb nutrients from food, often due to gastrointestinal disorders or surgical removal of parts of the digestive system
- Increased demand: Increased need for certain nutrients during periods of growth, pregnancy, or lactation
- Medications: Certain medications, such as antacids, that can interfere with nutrient absorption
- Chronic diseases: Certain chronic diseases, such as celiac disease or Crohn's disease, that can lead to malabsorption
Vitamin Deficiencies
- Vitamin A deficiency: Can cause night blindness, dry skin, and impaired immune function
- Vitamin B12 deficiency: Can cause fatigue, weakness, and neurological symptoms
- Vitamin D deficiency: Can cause bone weakness, osteoporosis, and increased risk of fractures
- Vitamin E deficiency: Rare, but can cause impaired nerve function and muscle weakness
- Vitamin K deficiency: Can cause bleeding disorders and impaired bone health
Mineral Deficiencies
- Iron deficiency: Can cause anemia, fatigue, and weakness
- Zinc deficiency: Can cause impaired growth, wound healing, and immune function
- Calcium deficiency: Can cause bone weakness, osteoporosis, and increased risk of fractures
- Magnesium deficiency: Can cause muscle cramps, weakness, and heart rhythm disturbances
- Potassium deficiency: Can cause muscle weakness, fatigue, and heart rhythm disturbances
At-Risk Populations
- Pregnant or breastfeeding women: Increased demand for certain nutrients
- Vegetarians and vegans: Risk of vitamin B12 deficiency
- Older adults: Decreased ability to absorb nutrients
- People with chronic diseases: Increased risk of malabsorption
- People taking certain medications: Increased risk of nutrient deficiency
Diagnosis and Treatment
- Blood tests: Used to diagnose vitamin and mineral deficiencies
- Dietary changes: Increasing consumption of nutrient-rich foods
- Supplements: Taking vitamin or mineral supplements to address deficiencies
- Medical treatment: Addressing underlying medical conditions that contribute to deficiencies
