One of the major problems that both the developed and under-developed countries are facing is the difficulties of treating illhealth
people. There is shortage of medical expertise in various hospitals, most of these countries are spending affluence of their
resources to meet this challenge but still they are unable to meet the demands of providing good medical services for their people.
It has become of great concern to find a lasting solution to the problem of traditional method of medical diagnostic which is
characterized by inaccuracy and imprecision. Many researchers have developed several algorithms and technologies (including
Fuzzy Logic, Genetic Algorithms and even Artificial Neural Network) to ensure accuracy and precision in the field of medicine
which are branches of Artificial Intelligence. This paper covers the development of a medical diagnostic system using fuzzy
logic; so as to enhance the accuracy and precision of medical diagnosis. The proposed medical diagnostic system was developed
using Visual Prolog Programming language. The proposed system proffers solution to the enormous responsibilities of the
diagnostic process carried out by medical personnel using fuzzy logic. More advance medical diagnosis system can be designed
to help in the area like drugs prescription, registering of patients as well as keeping of patients’ details and records in the medical
sector
