REASONS FOR MONSPLASTY
In the pubic area, a tendency to have more fat can be something you are born with, also known as congenital. Some individuals can be of average weight or even underweight and have a prominent mons pubis in this area due to a genetic disposition for targeted fat collection.
A bigger mons pubis may come with weight gain, too. Finding an obese woman or man who does not store excess fat in the pubic area is rare. Also, the skin in the pubic area can become lax and start to sag.
Suppose you have had surgery, such as Abdominoplasty or Liposuction, to flatten your abdomen. You may start noticing your pubic fat even though the pubic area has not seen any physical change. Flattening the abdomen could make the region of the pubic appear to stick out more.
After liposuction, the pubic area may temporarily appear larger because gravity pulls swelling downward from the abdomen towards the mons pubis.
