E10.51: Type 1 diabetes mellitus With peripheral circulatory complications Uncontrolled

You have diabetes. This is also known as diabetes mellitus.

The sugar from food or from sweet drinks is absorbed via the intestine. The sugar gets into the blood there. As a result, the sugar level in the blood rises after eating. The pancreas produces the messenger substance insulin. The pancreas is located in the upper abdomen. Insulin ensures that the sugar from the blood is absorbed into the cells. After eating, especially, the pancreas releases insulin into the blood. As a result, the sugar level in the blood then drops back.

Insulin is produced by specific tissue in the pancreas. Your immune system has produced antibodies to combat this tissue. Over time, these antibodies destroy the tissue. As a result, the pancreas is gradually able to produce less and less insulin. If there is too little insulin in the blood, the cells can no longer absorb the sugar from the blood properly. The sugar content in the blood may then be persistently too high. This is called Type 1 diabetes mellitus.

With diabetes, the sugar level in the blood is usually too high. If the diabetes is treated with insulin or other medications, however, the sugar level can also drop sharply.

Your diabetes is currently out of control. Diabetes is deemed to be out of control when the blood sugar content is either very high or far too low at a certain point in time. But it may also be that the blood sugar content is repeatedly too high over a longer period of time.

The high sugar level has damaged your blood vessels. Fats and calcium can be deposited in the wall of damaged blood vessels. The deposits can constrict the blood vessels. When blood vessels get constricted, circulatory problems can occur. For example, wounds may consequently not heal as well. This may also impair the blood supply to individual organs. So the diabetes can increase the risk of heart attack or stroke. Then the blood supply to areas of the heart or brain is impaired. The kidneys, eyes or skin may also be affected by the circulatory disorders.

Additional indicator

On medical documents, the ICD code is often appended by letters that indicate the diagnostic certainty or the affected side of the body.

  • G: Confirmed diagnosis
  • V: Tentative diagnosis
  • Z: Condition after
  • A: Excluded diagnosis
  • L: Left
  • R: Right
