Thank you for your question about telling if you need a thigh lift, in regards to your particular situation. I would suggest you lose as much weight as you possibly can. If you plan on losing more weight, lose the weight, and then once the weight has stabilized then, consider thigh surgery; it is possible that when you have reached your weight loss goal, the areas of excess fat on your thighs will be gone. If your inner thigh's excess skin and fat are still there once you reach your weight loss goal, you may consider a thighplasty. Depending on the condition of your inner thigh, this may require thigh liposuction or incision of excess thigh skin and fat if you need an excision of excess thigh skin and fat. This will require a crescent or mini thigh lift, thigh reduction, or thighpalsty. If it is more extreme, you may need an incision from the groin or half way to the knee,. This is called a modified thigh lift or a full thigh plasty, respectfully. I would lose the weight and wait for your weight to stabilize. Once you are at a stable weight that you are comfortable with, then, I would reevaluate the thighs. I hope this helps to answer your question regarding how to tell if you need a thigh lift.
