Health literacy involves the information that people need to be able to make good decisions about health. There are two parts:

• Personal health literacy is about how well a person can find and understand the health information and services that they need. It is also about using the information and services to make good health decisions.
• Organizational health literacy is about to how well organizations help people find the health information and services that they need. It also includes helping them use that information to make good health decisions.

Many different factors can affect a person's health literacy, including their:

• Knowledge of medical words
• Understanding of how the health care system works
• Ability to communicate with health care providers
• Ability to find health information, which may require computer skills
• Reading, writing, and number skills
• Personal factors, such as age, income, education, language abilities, and culture
• Physical or mental limitations

Many of the same people who are at risk for limited health literacy also have health disparities. Health disparities are health differences between different groups of people. These groups may be based on age, race, gender, or other factors.

Health literacy is important because it can affect your ability to:

• Make good decisions about your health
• Get the medical care you need. This includes preventative care, which is care to prevent disease.
• Take your medicines correctly
• Manage a disease, especially a chronic disease
• Lead a healthy lifestyle

One thing that you can do is to make sure that you communicate well with your health care providers. If you don't understand something a provider tells you, ask them to explain it to you so that you understand. You can also ask the provider to write down their instructions.
