Prediabetes
Prediabetes
What it means
Prediabetes means that your blood glucose, or blood sugar, levels are higher than normal but not high enough to be called diabetes. The National Cancer Institute (NCI) dictionary describes it as a common condition in which glucose levels in the blood are higher than normal but not high enough to be diagnosed as type 2 diabetes. MedlinePlus explains that prediabetes usually happens when the body has a problem with insulin, a hormone that helps glucose get into the cells for energy. People with prediabetes are more likely to develop type 2 diabetes, heart disease, and stroke. Most people don't know they have prediabetes because usually there are no symptoms. Blood tests can diagnose it; the most common ones are the fasting plasma glucose (FPG) test and the A1C test.
Prediabetes in Spanish
- Spanish term

- Gender and article
- feminine: la prediabetes
- Pronunciation
- preh-dyah-BEH-tehs
Prediabetes is written the same way in Spanish and English. MedlinePlus en español defines it with the sentence Prediabetes significa que los niveles de glucosa o azúcar en la sangre son más altos de lo normal pero no lo suficientemente altos como para ser diabetes. The word is feminine: MedlinePlus en español asks ¿Qué es la prediabetes?, and the Spanish page of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) begins its definition with La prediabetes significa. The National Cancer Institute's Spanish dictionary adds four other names at the end of its entry: diabetes asintomática, diabetes latente, diabetes química and diabetes subclínica.
Vocabulary on the same pages: resistencia a la insulina (insulin resistance), azúcar en la sangre (blood sugar), prueba de glucosa plasmática en ayunas (fasting plasma glucose test), prueba de A1c (A1C test) and cambios en el estilo de vida (lifestyle changes). The two sources name the disease differently: MedlinePlus en español writes diabetes tipo 2, and the National Cancer Institute dictionary writes diabetes de tipo 2.

Your right to an interpreter in the United States
If English is not your primary language and you have difficulty communicating in English, you may need an interpreter or a translated document when you visit a doctor or dentist, go to the emergency room or pick up a prescription. The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.
You can ask when you make the appointment or at the front desk: "I need an interpreter, please." «Necesito un intérprete, por favor.»
