Am I losing to much?

I need some advice. I had gs done on July 30 2015, and by aug. 7 2015 I had already lost 20 lbs. Should I be concerned about losing do much weight so quickly?

I lost a lot of weight in the first and second week. It's slowed down for the 3rd and 4th. I talked to my dietician about it and she wasn't concerned.

Most people here would be thrilled. Your main concern should be getting your fluids and getting as much protein in as you can. The fluids are even more important because it is easy to get dehydrated at this stage. You must have a follow up appointment soon, so if you are still concerned ask. You may have just lost a lot of water weight. I lost 11 pounds in 7 days and then went into a 3 1/2 week stall. If you are not feeling well in some other way, then I would call, but if you are getting fluids and protein in and generally feeling good, I would rejoice!

That was the problem. I couldn't keep the shakes down. It felt like I couldn't get enough water in. I finally figured out that if I drink 4oz of shakes at a time I was able to. Ty for advice

I agree with NYMOM if you are feeling good. Enjoy the large loss!! I would love it! You didn't say how much you have to lose. Sometimes the more you have to lose will also aid in losing a lot fast in the beginning. Enjoy the large loss. You will find times you think your never going to drop another pound. :)

I have felt week a couple times like I wanted to fall.

Weakness is likely not lack of food, but dehydration. Before surgery, many people only drink while they eat, and if they aren't eating, they aren't drinking either.

Your profile says your BMI is 56.8 (not sure if that's accurate)?  I say it's completely normal.  I lost 25 lbs my first month and I "only" had 100 to lose.

Yes bmi is correct. My normal weight is 146. I started at 378 and now weigh 331. Goal weight I have no idea. Realistically I would say 199, but hoping got more. Doctor did not give me a goal weight.

You should be thankful. As long as you are getting in your protein and fluids, you are good. You need to take advantage of the first year to lose as much as you can. My starting BMI was 53 and I lost 29 pounds the first month. By 6 months you should expect to lose around 50% of your excess weight and by then is starts to slow down.
