Hair Loss After Gastric Bypass Surgery

Question Below Submitted By:  

Mary Ann (a patient from Delaware)

My gastric bypass surgery was March 25, and I’ve been noticing when I comb or brush my hair, it comes out. While my hair does not come out “in clumps”, more comes out than usual.

I’m drinking my required protein shakes per day, preferring that over eating hot food, having to buy so many different things, and just plain not liking to cook.

As for food, when I cook my husbands meals, sometimes I’ll eat a small amount of meat (fish, poultry, beef), maybe a very small amount of mashed potatoes or sweet potatoes, and lately have been craving vegetables, so I’ve been eating non-starchy veggies.

I’m taking the Vitamins as prescribed. The only thing I haven’t taken is my Thyroid Med, so need to check with my PCP about that.

I’ve read that Vinegar is good for thinning hair. It doesn’t look noticeable and there are no bald spots.

Could it even possibly be just that time (every certain number of years) that hair is shed?

I am 60 years old. Also, could pre-natal vitamins help (or hurt)?

Thanks for any and all responses.

Mary Ann

Hi Mary Ann,

Congrats on starting your weight loss journey this year! Losing some hair after bariatric surgery occurs in about 50% of patients. Losing weight rapidly even without bariatric surgery can lead to some hair loss.

So, no worries, it should come back with time...usually, after your weight loss slows or stops.

In the meantime, just make sure you are getting the optimum amount of protein in per day, usually 80 grams.

Taking hair and nail vitamins, or using Biotin shampoo helps for some patients.

Good Luck,
Troy LaMar MD

What hair I have is terrible

by: Marcy

I don't even get my hair cut anymore. I had a gastric bypass in 2012. I used to have very long thick curly hair but now it is thin, fine and very short. I take all the recommended supplements but I still look like a cancer patient.
