Vitamin deficiencies, even mild ones, are widespread in older adults, especially among frail or institutionalised seniors. Persistent tiredness despite sufficient rest and cracked lips rank among the most common symptoms. But what causes vitamin deficiencies?
Causes of Vitamin Deficiency in Older Adults
Poor Dietary Intake
Seniors often consume fewer calories from reduced appetite, activity levels, or fixed incomes limiting food purchases. This leads to inadequate intake of vitamins like B6, B12, and D, especially if fresh fruits, vegetables, or fortified foods are skipped.
Absorption Challenges
Ageing reduces stomach acid and digestive enzymes, impairing absorption of B12 and calcium. Thinner skin limits vitamin D synthesis from sunlight, while gut changes hinder calcium uptake.
Medication Effects
Many seniors take drugs that interfere with nutrient absorption, such as those inactivating pyridoxine or blocking B12. Prolonged use of anti-seizure meds or others heightens deficiency risks.
Lifestyle Factors
Alcoholism, smoking, or limited mobility reduce nutrient access and increase requirements. Cognitive issues like forgetfulness also contribute to inconsistent eating.
Addressing vitamin deficiency in seniors starts with awareness of these common causes. Recognising these factors empowers better choices, from nutrient-rich foods to regularly consulting healthcare providers.
