The condition and the treatment(s)
In diabetes the amount of glucose (sugar) in the blood is too high, which can lead to serious health problems. Insulin is a hormone made by the body to control the level of sugar in the blood. Type 2 diabetes occurs when the body can't make enough insulin, or when it can't use the insulin it produces properly.
Empagliflozin works by blocking re-absorption of blood sugar by the kidneys, increasing the amount of sugar removed from the body in the urine. This reduces the amount of sugar in the blood.
