Alcoholism after gastric bypass: Is it in your mind or gut?

My latest piece for Scienceline explores the mysterious link between gastric bypass surgery and alcoholism. Scientists think it’s undeniable that patients are developing alcoholism at higher rates after gastric bypass surgery. But they still don’t know why. Some reigning theories suggest patients may be transferring food addictions to other substances, the surgery may alter alcohol metabolism in patients’ guts or that a gastric bypass may even trigger changes in the central nervous system, affecting how patients process dopamine, a neurotransmitter that modulates our brain’s reward circuit and plays a large role in addiction. I’m pretty happy with how this piece turned out and hope you enjoy reading it!
