good thing you are taking the first step. it appears to be heriditary with your family history. I would :

change your diet to healthy foods (no breads, fried foods or junk foods)

drink more water before any meals.

eat more green vegetables and fruits..no iceberg lettuce or salad dressings

start walking more, exercise and look into surgery as well like the LapBand ,  Liposuction or Gastric Bypass remember just getting the surgery does not fulfill everything. you will need to change your lifestyle to becoming healthy overall.  ( eating the right foods, not starving yourself; just eat right and be more active, (walk, bike, hike, etc....you don't have to be a gym rat each day)
