E10.01: Type 1 diabetes mellitus With coma 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.

Your diabetes is currently very out of control. Diabetes can get very out of control if you need more insulin than usual. This is the case with infections or serious illnesses, for example. The diabetes can also get very out of control if the elevated blood sugar is not treated adequately. Diabetes is deemed to be very out of control when the blood sugar content is either very high or far too low at a certain point in time.

Due to the high sugar level in your blood, the water balance and mineral balance in your body have changed. We need a certain amount of water in our body if the individual cells are to work properly. The mineral balance in the blood and cells also has to be within a certain range for the body to be able to function. A high blood sugar level results in having to urinate very often. This causes the body to lose a lot of water and minerals via the urine. Certain processes in the body are then unable to function properly.

If the diabetes has got very out of control, there can be a variety of symptoms. You may be very thirsty. You may also feel dizzy. You may feel nauseous or need to vomit. You may also pass out. The person is then very ill.
