An Albanian man’s pain grew so unbearable, he said, he pulled out his own tooth as he languished for months in a New Mexico immigration detention center. A Honduran mother of two said she was hospitalized for a heart problem after she was denied blood pressure medications while held in Florida. A Venezuelan man said his leg grew purple and swollen from flesh-eating bacteria when staffers at a Vermont facility did not bring him to a scheduled doctor appointment.

Hundreds of detainees across at least 33 states allege in federal suits that immigration detention facilities are failing to provide adequate medical care, an investigation by KFF Health News and The Associated Press found. Detainees say they didn’t get medications on time — or at all — for conditions including high blood pressure, diabetes, depression, epilepsy, Parkinson’s, and HIV. Requests for help went unanswered for weeks. Blood sugars rose. Infections festered. Cancers remained untreated. Detainees collapsed and had seizures.

U.S. jails and immigration detention centers have long struggled to meet the medical needs of the people in their charge. But the system is sagging under an influx of detentions since President Donald Trump returned to office: More than 75,000 immigrants were being detained by U.S. Immigration and Customs Enforcement as of mid-January, up from around 40,000 a year earlier.
