E13: Other specified diabetes mellitus

Other specified diabetes mellitus refers to a group of conditions characterized by a high level of sugar, or glucose, in the blood over a prolonged period. Unlike Type 1 and Type 2 diabetes, this group of conditions constitutes less common variations of diabetes resulting from specific causes. These can include genetic defects affecting the function of the pancreas, which produces insulin or endocrine disorders where other glands interfere with insulin production. The common symptoms across these variations include frequent urination, increased thirst, excessive hunger, blurred vision, and fatigue. Over time, a continuously high blood sugar level can lead to severe complications affecting vital organs and systems in your body, including the heart, blood vessels, nerves, eyes, and kidneys. If left uncontrolled, it can even lead to stroke, heart disease, and kidney failure.
