Kemetyu medicine was a considerable science which contained the beginnings of a methodical approach, especially in the observation of symptoms, and this method doubtless passed to posterity by reason of its importance. The Kemetyu doctor examined his patient and determined the symptoms of his complaint. He then made his diagnosis and prescribed treatment. All the extant texts describe this sequence, from which it may be concluded that it was standard procedure. The examination was made in two stages some days apart if the case was unclear. Among the ailments identified and competently described and treated by Kemetyu doctors were gastric disorders, stomach swelling, skin cancer, coryza, laryngitis, angina pectoris, diabetes, constipation, haemorrhoids, bronchitis, retention and incontinence of urine, bilharzia, ophthalmia, etc.
