E10-E14: Diabetes mellitus

E12: Malnutrition-related diabetes mellitus

Malnutrition-related diabetes mellitus, classified under the E12 code in the ICD-10 WHO 2016 classification, is a group of conditions that concern the body's inability to regulate the sugar level in the blood due to prolonged malnutrition. These conditions occur when the body doesn't make enough insulin, or can't use it properly, due to deficiencies in nutrients caused by a poor diet over a long period of time. Typical symptoms include frequent urination, excessive thirst, and unexplained weight loss. As the disease progresses, if not well managed, it can lead to complications affecting various organs and systems including the heart, kidneys, nerves, and eyes. It's key to know that although malnutrition is the main cause, lifestyle and genetic factors can also play a role in the development of these conditions.
