What are some consequences of limited health literacy?

• A. Less likely to protect health, more likely to have poorly controlled chronic conditions, and higher rates of hospital readmission.
• B. More likely to achieve optimal health.
• C. No impact on health outcomes.
• D. Lower healthcare costs.

Answer: (A)

Understanding health information and how to act on it is essential for staying healthy. When health literacy is limited, people often struggle with reading and understanding medical instructions, medication labels, dosage schedules, and when to seek care. This makes it harder to protect health and properly manage ongoing conditions.

Because self-management of chronic diseases like diabetes, high blood pressure, or asthma relies on following treatment plans, poor comprehension leads to less effective control of these conditions. When chronic illnesses aren’t well managed, symptoms worsen, complications arise, and the likelihood of hospital visits increases. That pattern of inadequate disease control and more frequent hospital readmissions is exactly what is observed with limited health literacy, and it typically translates into higher overall healthcare costs due to more acute care needs and frequent utilization of services.

So, the answer highlights the real-world consequences: reduced ability to protect health, poorer control of chronic diseases, and higher readmission rates. The other options conflict with evidence showing that limited health literacy generally worsens health outcomes, can increase costs, and does not lead to better health or no impact.
