Poor people with diabetes are significantly more likely to go to the hospital for dangerously low blood sugar at the end of the month when food budgets are tight than at the beginning of the month, a new study has found. Researchers found no increase in such hospitalizations among higher-income people for the condition known as hypoglycemia, suggesting that poverty and exhausted food budgets may be a reason for the increased health risk. Hypoglycemia occurs when people with diabetes have not had enough to eat, but continue taking medications for the disease. To control diabetes, patients need to keep their blood sugar within a narrow band.
