How does medication impact nutrition in older adults?

Medications can significantly impact nutrition in older adults by causing side effects that interfere with appetite and nutrient absorption. This is particularly important to consider in gerontology, where polypharmacy—taking multiple medications—is common. Some medications may lead to gastrointestinal side effects such as nausea, vomiting, or diarrhea, which can decrease appetite and restrict a person's ability to consume adequate nutrition. Additionally, certain drugs can affect the way nutrients are absorbed in the body. For instance, some medications can bind to nutrients in the gastrointestinal tract, making them less available for absorption. This can lead to deficiencies in essential vitamins and minerals, further complicating the nutritional status of older adults. Understanding the relationship between medication and nutrition is crucial for healthcare providers to manage the health and dietary needs of this population effectively.
