I'm going to be sleeved on August 25th and I've already been on the pre op diet for about a week and a half. My doctors pre-op diet consists of four hmr 70 Protein shakes and 1 small meal which adds up to about 1020 calories.

I have PCOS and before being on birth control, I was a hormonal nightmare. It was downright frightening because I would go through heavy swings of depression and anger. But I worked with my OBGYN and it's gotten better. I haven't really had any trouble since.

Until today.

I found myself yelling and crying and angry with my boyfriend who stayed very calm and who had done absolutely NOTHING wrong. However I didn't realize he had done nothing wrong until after hanging up the phone and sitting on the steps for a while. I had never yelled at him like that. I felt like I had just shot Bambi.

He was great about it and joked that now he was prepared for what I'd be like if I ever got pregnant. Haha

But, it brought up some major concerns for me. Has anyone else going themselves going through major mood swings? Could it be because I'm not eating as much? Ever since I was younger, I'd get mood swings when I was super hungry because of the hormones and insulin resistance.

My biggest question is, could this get worse post op? I know that my stomach will be smaller so I won't be as hungry. But I'm seriously concerned that during the liquids phase I will turn into a crazy hormonal tornado simply because of the lack of calories. Or, Heaven forbid, that it might last past that.

If anyone has any thoughts, I'd super appreciate it! I'm ready to live a happier and healthier life. But I'd rather not bite my loved ones heads off in the process.

Absolutely. The entire 4 weeks post op while I was on a liquid diet, my husband probly wanted to move out. He also stayed pretty calm while I lit into him everyday. Basically cuz he could eat food and I couldn't. Pissed me off. While he wasn't eating junk (he's an Atkins follower), he could actually chew his food and I was jealous.

Lack of food and hormones regulate our moods. Plus I take an antidepressant, which I'm sure has a little to do with my moods.

Good luck with ur pre op diet. Ur one of the lucky ones who actually gets to eat food, once a day. I was a really lucky one. Had NO pre op diet except 24 hrs of Clear Liquids before surgery.
