Internet addiction disorder, also known as problematic internet use or compulsive internet use, refers to excessive and compulsive use of the internet that disrupts daily life and causes significant distress. It is characterized by spending excessive time online, neglecting personal responsibilities, and experiencing withdrawal symptoms when unable to access the internet.

They may experience social isolation, decreased productivity, and negative effects on their mental and physical health. Common activities that contribute to internet addiction include gaming, social media, online shopping, and pornography.
