Lifestyle Diseases Dataset – Preventable & Lifestyle-Related Conditions
Lifestyle Diseases Dataset
The Lifestyle Diseases Dataset is a structured medical database containing a comprehensive list of health conditions influenced by lifestyle factors such as diet, physical activity, smoking, alcohol use, and stress.
Lifestyle diseases—also known as non-communicable diseases (NCDs)—are among the leading causes of death worldwide. Conditions such as obesity, type 2 diabetes, cardiovascular diseases, and certain cancers are strongly linked to lifestyle behaviours.
This dataset provides organised information about these conditions, helping researchers, developers, and healthcare professionals analyse risk factors, prevention strategies, and treatment approaches.
Each record includes detailed clinical and lifestyle-related information such as disease descriptions, affected systems, common symptoms, severity levels, and contributing lifestyle risk factors.
The dataset has been cleaned and structured for easy integration into spreadsheets, databases, and analytics tools.
It is ideal for public health researchers, wellness app developers, educators, and data scientists working on prevention-focused health solutions.
