Which condition is referred to by the abbreviation "DM"?

The abbreviation "DM" commonly refers to Diabetes Mellitus, a chronic condition that affects the way the body processes blood sugar (glucose). In this condition, either the body does not produce enough insulin or the cells become resistant to insulin, leading to elevated blood glucose levels. Understanding Diabetes Mellitus is vital for health professionals as it requires careful management to prevent complications such as heart disease, kidney damage, and nerve damage.

The other options represent terms that are less commonly associated with the abbreviation "DM." For instance, Degenerative Muscle could refer to muscle degeneration conditions but is not widely recognized by the abbreviation DM. Similarly, Doctor's Management and Delayed Maturation do not refer to established or commonly used medical terms associated with "DM." Thus, the clear and well-accepted definition is that "DM" stands for Diabetes Mellitus, making it the correct choice in this context.
