How common is hair loss after bariatric surgery?

Bariatric surgery: Loss of hair is common

I've seen dozens and dozens of patients these past few months experiencing hair loss after bariatric surgery. This hair loss is mostly of the telogen effluvium kind and a large proportion of the hairs are expected to grow back. A proportion of people don't quite regain the same density as they once had -  a phenomenon whereby hair shedding episodes are said to accelerate the development of androgenetic alopecia. 


How common is hair shedding after bariatric surgery?

I enjoyed reading a new study from Brazil which showed that quality of life is enhanced greatly following the weight loss from bariatric surgery. In the study, hair loss was common following the surgery and occurred in nearly 70 % of those that have surgery.
