Diabetes insipidus
Diabetes insipidus is a rare condition where you produce a large amount of urine and often feel thirsty.
Needing to frequently pass large amounts of urine and feeling thirsty are the two main symptoms of diabetes insipidus.
Diabetes insipidus is caused by problems with a chemical called antidiuretic hormone (ADH), which is also known as vasopressin.
See your GP if you have the symptoms of diabetes insipidus. They'll ask about your symptoms and carry out a number of tests.
Treatments for diabetes insipidus aim to reduce the amount of urine your body produces.
Diabetes insipidus can sometimes cause complications, particularly if it's undiagnosed or poorly controlled.
