Beware of Overdiagnosis!

Just consider one fact from India - almost 50% of the cases of thyroid diseases, breast cancer, high BP, prostate cancer & TB are due to Overdiagnosis. These cases don't need any treatment as they will never lead to problems over entire remaining lifespan of the individual.

However, unfortunately, these cases are also treated like those who need immediate treatment like hospitalisation, medicines, insurance, expenses etc. Leading to lifelong misery.

Right diagnosis helps you in getting correct treatment & frees you from suffering. Underdiagnosis continues your suffering due to the disease. Overdiagnosis creates unnecessary suffering as you go through treatment that is not at all necessary.

Overdiagnosis in medicine refers to the identification of a condition that would not have caused symptoms or harm during a person’s lifetime if left undetected. In the Indian context, overdiagnosis is Influenced by factors such as widespread screening programs, increased availability of advanced diagnostic tools, cultural attitudes toward medical testing, economic incentives in healthcare, and a lack of standardized guidelines tailored to India’s diverse population. While comprehensive, India-specific data on overdiagnosis is limited, the phenomenon can be inferred from global trends, local healthcare practices, and the biological variability prevalent in the country (e.g., genetic diversity, dietary habits, and environmental factors). Below is a list of 100 examples of potential medical overdiagnosis in India, categorized by condition or diagnostic practice, with explanations grounded in the Indian healthcare landscape.

 Overdiagnosis can lead to unnecessary treatments, psychological distress, financial burdens, and medical complications, particularly in a resource-constrained and diverse country like India. The consequences are tailored to the Indian context, considering factors such as healthcare access, socioeconomic disparities, and cultural attitudes toward medical interventions.

Broader Implications in India

The consequences of overdiagnosis in India are amplified by limited healthcare resources, out-of-pocket expenses (often >60% of costs), and variable access to follow-up care. Unnecessary treatments strain families financially, increase antimicrobial resistance (e.g., in TB or typhoid cases), and overburden public health systems. Psychologically, patients may face stigma (e.g., TB, mental health) or lifelong fear of “disease.”
