Bond funds typically own a number of individual bonds of varying maturities, so the impact of any single bondâs performance is lessened if that issuer should fail to pay interest or principal.

1 Medications such as metformin, exenatide and a class of drugs called the thiazolidinediones can help improve insulin resistance. 2  These are approved in the treatment of type 2 diabetes but not for the treatment of insulin resistance alone.
Metformin attaches to the surfaces of cells and increases their ability to take in glucose. The drug also reduces glucose production in the liver. Metformin is the only drug that should be considered for use in insulin resistance or pre-diabetes to prevent diabetes onset, the American Diabetes Association suggests.
