The honeymoon phase is a term used in Type 1 Diabetes. It refers to the phase after the diagnosis of Diabetes, wherein the remaining beta cells in the pancreas produce sufficient Insulin for the body. Thus, during this phase there will usually be no diabetes symptoms. But as time goes by, more cells will be killed by the body’s immune system, and the production of sufficient amounts of insulin will cease. Following that, diabetes symptoms may start manifesting. The honeymoon phase can last from up to three months to one year.
