Hoarding is a condition where individuals obsessively collect personal items or trash due to a perceived need to keep them. There are 5 stages of hoarding, with progressive stages being more severe than the previous. The least severe stage involves light clutter and few indicators, while the most severe stage involves fire hazards, no electricity or running water, and accumulated human and animal feces. Hoarding can have emotional, physical, financial, and legal consequences for the hoarder and those around them. Proper understanding and intervention can help individuals suffering from hoarding.
