Diagnosis and Treatment
Overview of Diagnosis and Treatment
- Diagnosis is the identification of the nature of an illness or other problem by examination of the symptoms.
- A variety of techniques, including physical examination, medical history taking, laboratory tests, and imaging, are used in diagnosis.
- Treatment includes the procedures performed to cure disease, halt the progression or slow the pace of disease, relieve symptoms or mitigate suffering.
Physical Examination and History Taking
- A physical examination involves a healthcare provider observing a patient for any signs of disease.
- In a thorough physical examination, the doctor uses their senses of sight, hearing, touch, and sometimes smell (e.g., in infection and metabolic disorders).
- Medical history taking is a conversation in which the doctor asks the patient questions about their symptoms, previous conditions and treatments, lifestyle habits and other relevant factors.
Laboratory Tests and Imaging
- Laboratory tests involve the examination of body fluids (like blood or urine) or tissues.
- These tests can help to identify infection, genetic disorders, biochemical imbalances and other underlying conditions.
- Medical imaging uses techniques such as X-rays, MRIs, and ultrasounds to create visual representations of the inside of the body for clinical analysis and medical intervention.
Treatment of Diseases
- Cure is the complete eradication of a disease from the body. Not every disease can be cured.
- Treatment may also aim to slow or halt progression of a disease if a cure is not possible.
- Treatment can also relieve symptoms, such as the administration of painkillers to relieve pain.
Pharmaceutical and Surgical Treatment
- Pharmaceutical treatment involves the use of medication to treat disease. Medicines can have a wide range of effects, from curing a condition to relieving symptoms or slowing disease progression.
- Surgery is a medical procedure that involves the physical alteration of body tissues in order to treat disease. It can be used to remove tumours, repair damage, or address abnormalities.
Chronic and Terminal Illnesses
- Chronic illnesses are long-term health conditions that may not have a cure. Treatments for these conditions often aim to manage symptoms and improve life quality.
- Terminal illnesses are progressive illnesses that have no cure and will likely lead to the patient’s death. Treatment aims to provide comfort and pain relief.
Mental Health Diagnosis and Treatment
- Mental health disorders are diagnosed based on patterns in thoughts, behaviours, and feelings. These could be through psychological assessments or medical history.
- Treatments for mental health disorders can include psychotherapy, medication and social intervention. The specific method often depends on the type of disorder and its severity.
