Hypoglycemia
Hipoglucemia
Also: Azúcar baja en sangre (regional variant)
What it means
Hypoglycemia means low glucose. It happens when the level of glucose in your blood drops below what is healthy for you: for many people with diabetes this means a level lower than 70 mg/dL, and for people who don't have diabetes it is typically lower than 55 mg/dL. It is common in people who have type 1 diabetes or who have type 2 diabetes and take insulin or other diabetes medicines. Symptoms tend to come on quickly and may include shaking, sweating, nervousness or anxiety, irritability or confusion, dizziness and hunger. Severe hypoglycemia can cause serious complications, including passing out, coma, or even death. If signs of low blood sugar do not improve after a snack that has sugar, MedlinePlus says to call 911 or the local emergency number.

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.»
