Functional medicine is an up-and-coming approach of diagnosis and treatment where physicians delve deeper into the root cause of disorders rather than treating them superficially. Treatments are tailored to every patient’s unique needs by scientifically analysing nutrient deficiencies, hormonal imbalances and unrelatable symptoms. Functional medicine has been maximally efficient in difficult to treat conditions like auto-immune disorders, persistent gut disorders, hormonal variations, and metabolic disorders. The ease with which it can be integrated into almost every treatment plan and its patient-centric way of dealing makes it an indispensable tool in holistic healthcare.
