My pubic area and penis is swollen after lipo. Why did this happen?

This is not uncommon at all. Swelling of the general region after lower abdominal surgery is fairly common and will resolve with time.

Swelling is essentially edema or excess water in tissues as a simplified explanation. Gravity makes water run down hill, in your case and others that would be in the genitalia region. No worries, it will resolve. 

this is very common and more common in hi definition procedures that do not use drainage tubes.  I suggest speaking to your phsyciain or reviewing your post operative instructions if you are concerned. Best, Dr. Emer.

Thank you for your question and I am sorry to hear about your swelling.  Often as a result of the fluid placed in the abdomen to safely perform liposuction the surrounding tissues will become swollen.  In addition, as you become more active with walking after surgery gravity will have a tendency of pulling this extra fluid downward, causing swelling of your pubic region and penis.  I would speak to your surgeon about care for the area, but using a compression garment, as well as time, will improve the issue.  

No matter what type of lipo is done, when it is performed on the lower abdomen and under local anesthesia, which I assume you had, this can be normal. 
The anesthetic fluid runs out through your lower incision but unfortunately some of the fluid can bypass the incision and  continue "south" and end up swelling your pubic area, penis and testicles. 
Usually, as you describe, it is pain free but somewhat frightening at first. Your body will absorb this excess fluid in time, usually a matter of days. 
Again, as long as there is no pain, redness or warmth in these tissues, it is normal. If these other signs appear, call your surgeon immediately. 
Also make sure that your garment is not too constrictive where your penis and testicles exit. This could significantly delay the resolution of this swelling.
Gentle massage, ie. lymphatic massage can help, also when lying down, elevate your pelvis with a pillow. 

Thank you for your question.  Swelling in the groin area after liposuction to the abdomen is normal.  Gravity pulls the swelling down and also if there is bruising it will pull the bruising down as well.  Keep your garment on which will help with the swelling. 

Hello dear, thanks for your question and provided information. It is normal to have swollen areas after a liposuction, you will be swollen because of the thighten of the faja during a month or more, do not worry, that will go away soon

This is very common following lower abdominal liposuction because of the gravity effect on swelling fluids going downward. This resolves in most cases over the course of 2 weeks. But why have you NOT seen your operative surgeon or even called him/her to obtain more detailed postop instructions and understanding of the operation you had? Tickle Lipo is just a marketing name for NOTHING new in liposuction... BTW
