Causes of vitamin deficiency

Older age is a time of life when health and wellness become a crucial priority. One of the most common challenges faced by seniors is vitamin deficiency, which can have a significant impact on their quality of life.

In this session, we will explore the underlying causes of this vitamin deficit in the elderly and how to address this problem to promote healthy and active aging.

Changes in nutrient absorption

As we age, our digestive system undergoes significant changes. The body's ability to absorb nutrients, including vitamins, decreases over time.

This is due to a decrease in the production of stomach acid and the efficiency of digestive enzymes. As a result, older people may have difficulty absorbing essential vitamins from food.

Inadequate diet

One of the most common causes of vitamin deficiency in the elderly is an inadequate diet. Some older people may have insufficient intake of vitamin-rich foods due to factors such as loss of appetite, difficulty chewing or swallowing food, or simply a lack of awareness of the changing nutritional needs at this stage of life.

Drug interactions

Older people often take a variety of medications to manage chronic medical conditions. Some of these medications may interfere with the absorption or metabolism of certain vitamins.

For example, proton pump inhibitors, common for treating acid reflux, may reduce the absorption of vitamin B12. It is important for healthcare professionals to be aware of these interactions and provide guidance on how to compensate for possible vitamin deficiencies.

Decreased sun exposure

Vitamin D, essential for bone health and the immune system, is synthesized in the skin through sun exposure. However, older people often spend less time outdoors, which can lead to vitamin D deficiency. This deficiency can be exacerbated in people with reduced mobility who spend most of their time indoors.

Mobility and food access problems

Older people who have mobility difficulties or who live in areas with limited access to fresh food may face difficulties in maintaining a balanced diet. Lack of access to vitamin-rich foods, such as fresh fruits and vegetables, may contribute to vitamin deficits in this population.

Socioeconomic factors

Socioeconomic factors, such as lack of financial resources or social isolation, may also influence the ability of older people to obtain adequate nutrition. The costs of nutritious foods, vitamin supplements, and medical care can be a significant barrier for those with limited incomes.

Strategies for Addressing Vitamin Deficiencies in Older Adults

Addressing vitamin deficiencies in the elderly requires a multidimensional approach. Health care professionals play a crucial role in assessing individual nutritional needs, identifying drug-drug interactions, and providing guidance on dietary changes.

In addition, it is essential to educate the elderly and their caregivers about the importance of a balanced diet and appropriate supplementation when necessary.
