question for those who have had top surgery, do you have to be a certain weight for top surgery ? im a bit chubby and concerned they might not do it for me, im 5"1 and about 189 pounds

I haven't had my top surgery but I believe it depends on the surgeon.  I also have this concern myself (being 5'4 and 250 pounds).  I think the best thing to do is ask your surgeon during the consultation how may your surgery be affected by your weightand what would be the best thing to do about it .  A bigger guy made a Youtube discussing his consultation with the same surgeon I choose and he asked those questions and what stuck out to the guy the most was the possibility of increased healing time and a greater chance if getting an infection.  Another the the guy said (in a message to me) was that if a patient is over 300 pounds then that could be a problem with the anesthesia.  The guy still went for it anyway and he happy with his results so I say just check with your surgeon about this.

Surgery isn't just a doctor cutting on you. It's putting your body under incredible stress. The only reason people don't go into serious shock during surgery and after while healing is because you're being taken care of by medical professionals. There's a reason there are some surgeries that require hospital stays. They have to make sure your not going to shut down and die.

That said, the healthier you are, the easier it is on your body to go through something so traumatic. Even if you're 100 pounds overweight, if you have a super healthy diet and cut out processed sugars (soda) and abstain from drinking and smoking a month or two before and after the surgery, you're setting yourself up to do much better with recovery than a person who's only 50 pounds overweight and doesn't eat healthy and drinks/smokes.
