Who discovered diabetes?

Diabetes was first described in Ancient Egypt in 1500 BC. The Egyptians called the disease "sweet urine", because they noticed that people with diabetes had urine that tasted sweet. Around 100 AD, the Greek physician Aretaeus of Cappadocia described diabetes in more detail, and he gave the disease its current name. In the 17th century, the English physician Thomas Willis further described diabetes, and he divided it into two types: diabetes mellitus (which is characterized by high blood sugar levels) and diabetes insipidus (which is characterized by low blood sugar levels).
