E23.2: Diabetes insipidus

You have too little of a specific messenger substance (hormone) in your blood. For this reason, you have to urinate very frequently.

Messenger substances affect many processes in the body. A particular messenger substance is affecting the concentration of dissolved sodium in the blood and urine. This messenger substance is called adiuretin. In your case, too little of the messenger substance adiuretin is being created. This happens for instance with various diseases in the brain. In very rare cases, the disease is congenital.

If you have too little of this messenger substance in your blood, then you have to urinate frequently. As a result, there may be insufficient fluid in your body. If there is too little fluid in your body, you may be extremely thirsty.

This disease has nothing to do with diabetes. With diabetes, the blood sugar is too high. This is known as diabetes mellitus.
