I'm new here,and supposed to have gastric bypass in March. I have been having so much depression and anxiety about this. I worry about not being able to eat foods I like, but have read on here from you guys that tastes change ,so that makes me feel better. I also worry about the hair loss, and is there anything I can take to help with that? any supplements maybe? Also, I worry about having sagging skin after weight loss, especially on the already lower abdominal fat/skin that is already hanging. What do people do?
Hi horizon & welcome. You have lots of valid concerns, I'm glad you found us.
Are you seeing a therapist about the depression/anxiety you're feeling? Finding a way to turn that into hope and excitement will make all the difference. Even introducing meditation and affirmations into your daily routine can work wonders. Try focusing on all the positive changes that you're looking forward to once you feel healthier, have more energy and yes... look amazing.
For most of us, there is hair loss between months 3-6 but if you're like me, it stops after a few months & starts growing back. I was fortunate that I have a lot of hair so I was the only one who noticed the thinning. Even my hairdresser didn't, she only noticed when she noticed a ton of regrowth coming in.
Sagging skin... sigh, unfortunately with significant weight loss, it goes with the territory.

The severity depends on your age, how long you've been obese, how much weight you loose, sun exposure, genetics and a multitude of other things. Unfortunately, it's a gamble. But please don't let this deter you! It's far better to get healthy and feel good. You can deal with the skin later if you need to. If it's causing medical issues (such as rashes, limited mobility, etc.) talk to your doctor about it right away. Make it a medically-documented problem & who knows, perhaps insurance would pay for some removal down the road. If not, perhaps you can look into financing body reconstruction down the road.
Good luck in your journey and keep asking questions, we're here to help anyone we can.
