The etiological notion of diseases and the methodology of treatment varies among different systems of medicine. However, the mode of disease diagnosis (Nosological diagnosis) is common for all systems. It's an undeniable fact that the close association between disease diagnosis and remedial diagnosis prevailed in Modern medicine might not be observed in other holistic systems, however, diagnosis is featuring its own importance even yet in other systems. The mode of treatment may be either holistic treatment, specific treatment, symptomatic treatment and general life support to the patient. Modern medicine gives more importance to the specific treatment, whereas, systems like Ayurveda, Homoeopathy, Siddha, Unani, Chinese medicine, Naturopathy etc. give more importance to the holistic idea of treatment, i. e. remedy section by considering the physical, mental and emotional characters and life situation of the sick individual.

However, in these systems also, disease diagnosis is equally important, because, under certain situations, the functioning of the affected organ or the device of your body needs to be backed up. The individual also may require some specific form of support, for that the organ remedies are to be deployed. Apart from that, disease diagnosis is very important to planning the disease control measures, prognosis, special precautions, to understand living threatening situations, prevention of spreading of disease to others. Diagnosis is extremely essential for statistics, research and also to fulfill the academic interests. Most importantly, due to some medico-legal reasons, the doctor should know the detailed health status of his patient. Due to all or any these reasons, disease diagnosis is a must, irrespective of the device of treatment directed at the patient.

Disease diagnosis and remedial diagnosis can be considered as the 2 sides of exactly the same coin, hence, both are experiencing equal importance. Disease diagnosis is performed by correlating the signs and symptoms of the patients (clinical features) with the information given by the bystanders and the lab investigation reports. On certain situations, there might be some difficulty in making a diagnosis, because, numerous diseases are having almost similar clinical features. Moreover, rarely occurring diseases or a recently emerged disease may possibly not be identified easily, especially by a general practitioner. Under such circumstances, a specialist's opinion might be needed. Very rarely, a group of doctors are involved in the process of diagnosis.

It's not possible to call each and every disease we run into in our everyday practice. As per the International Classification of Diseases (ICD-10), a significant percentage of diseases can't be named. In such cases, a diagnosis is possible regardless of having several health related symptoms in the patient. Since the individual is suffering, he must be treated symptomatically. Some symptoms or conditions are wrongly understood as diseases by the laymen. Like, clinical manifestations like jaundice, fever, vomiting, headache, malaise etc are not diseases; but clinical manifestations of some diseases. The naming of diseases is completed on several basis. All the diseases are named after the person who invented that particular disease (Buerger's disease, Alzheimer's disease, Weil's disease), some diseases on the foundation of area where in actuality the disease is common or identified for the very first time (African sleeping sickness, Madhura foot, Japanese encephalitis), on the cornerstone of some peculiarity of the outward symptoms (Chikungunya), or on the foundation of the organism responsible for the infection (Falsiparum malaria, Amoebic dysentery, Bacillary dysentery), or on the foundation of the affected organ (Myocarditis, Nephritis, Appendicitis), on the cornerstone of cause(Alcoholic hepatitis, Wool-sorter's disease), on the basis old (Juvenile rheumatoid arthritis, Senile dementia), on the foundation of pathology(Mixed connective tissue disease, Mucopolyscaccharidosis)etc.

If a small grouping of specific signs and symptoms are within a person, it is called syndrome (Edward syndrome, Down syndrome, Laurence-moon syndrome). Nowadays, we hardly locate patient having an individual disease, whereas most of patients are receiving a listing of diseases such as for instance cardiovascular disease, diabetes, idiopathic hypertension, acid peptic disease, senile dementia, degenerative joint disease etc. Many diseases are classified under certain band of disorders. Like: Degenerative joint disorders, Inflammatory bowel disorders, Psychosomatic diseases, Life-style disorders etc. Here, each group includes several diseases, but are grouped together due to some common features such as pathological or etiological features.

Each time a person comes to the physician for initially, immediate disease diagnosis may possibly not be possible because of various reasons. However, thinking about the presenting clinical features and history distributed by the patient, the doctor can come to a provisional disease diagnosis. After doing the laboratory investigations, the final diagnosis is completed by correlating the clinical findings with investigation reports. However the treatment is not kept in pending till the last diagnosis, especially in the event of life threatening diseases such as for example diphtheria, wherein the procedure has to be started immediately when the disease is suspected, because, if we watch for the lab reports to come, the individual may be critical. Some recent laboratory tests help in early diagnosis, but unavailability of sophisticated labs doing such tests is a major deficiency faced by many countries.

The development of science and technology has made a revolution in medical science. Now the concept of disease diagnosis done only on the basis of clinical examination is outdated. It's now underneath the custody of some sophisticated machines and laboratory techniques, a few out of them pose more risk to the health. But, the noteworthy point is, under all lab reports, a disclaimer is written as "correlate with clinical findings", which emphasizes the significance of case taking and clinical examination done by the doctor. In this era, wherein doctor-patient relationship is disrupted, we encounter many patients saying that the doctor has abruptly prescribed the medicine or referred for lab test without asking much questions and doing any sort of clinical examination.

The recent studies conducted at Mc Master university on the illness diagnosis is remarkable. They discovered that the name of the condition creates more panic on the list of patients. For instance, a person having sour eructation might not feel bad when a doctor says he has acidity, on another hand, he might get embarrassed if the doctor tells him he has Gastro-esophageal reflex disease, that will be the medical terminology for recurrent burning eructations. A similar thing happens in all of the cancer patients; once the illness is diagnosed as cancer, the patients mental and emotional status starts deteriorating. But, the physician cant hide the illness from the in-patient due to many medical and legal issues. The better alternative is always to secretly tell the diagnosis to the bystanders of the patient.

For a precise disease diagnosis, the cooperation from the patient and his family unit members is very essential. Each and every problem felt by the patient must certanly be told to the doctor. Some silly matter for the patient might be a vital point for a diagnosis and treatment. Similarly, apparent symptoms of long duration may be ignored by some patients. Purposeful hiding of symptoms could be dangerous. Some patients don't tell the physician about the procedure he had taken previously. Frequent change of doctor (doctor shopping) also can cause difficulties. During consultation, patients habits, life situations, characters, food and bowel habits, relationship with others etc must certanly be told. The reports of previous treatment and investigations must be told, that might save the time necessary for a diagnosis. Hence always request a discharge summary while getting discharged from any hospitals. While consulting a health care provider, always take one person who knows about the patient. The individual can also make a note of his symptoms before opting for a consultation, so he will not forget to inform his symptoms completely. In this busy life, there is a tendency that rather than patient likely to the doctor, he sends somebody to a doctor for a "consultation ".Also there is a rise of men and women preferring over-the-counter purchase of drugs with no prescription.

When a patient dies or becomes serious through the span of treatment, the next thing is always to file a suit against a doctor or by attacking the doctors and hospitals, consequently of a mental outbreak and a preconceived idea that it absolutely was because of medical negligence. Nowadays this is a common story in all of the news papers. By promoting the doctor-patient relation ship (which is deteriorating nowadays), and also by going back again to the "outdated" family doctor concept, we could solve most of the health related issues.
