I have really huge legs. Do you think I have lipedema? (Photo)

big legs doesnt mean lipedema but It can.  loose skin and disproportionate fat needs liposuction and/or skin tighteing and skin removal.  please see an expert this is a very specific procedure that needs very specific work (see link).
You need a formal evaluation by an expert in body shaping and contouring to determine what is best.  Traditional liposuction awake and smart liposuction are old methods and do very poorly for tightening skin or significant skin tightening or contouring.  Small problem areas can be improved slightly by these methods.  The best in body contouring not only removes fat with energy devices like VASER ultrasound but also internally heat the skin with radio-frequency devices such as J PLASMA/RENUVION, InMode BodyTite, ThermiRF to heat the under surface of the skin and tighten it at the same time as fat removal. These combinations are called 4D HIDEF VASER contouring and can only be done by a well . trained body contouring specialist. At the same time fat should be harvested, PRP and stem cells added and injected into muscles or indentations/cellulite to get body shaping and contouring.  This is known as a Brazilian butt lift when you inject the fat to the buttock for contouring and lifting, but fat can also be used in areas such as the chest/breast, arms/shoulders, calves and face.  Cellulite should also be treated with cellfina, sculptra, subcision and/or fillers such as bellafill, renuva synthetic fat, or sculptra.  If skin is very loose before surgery then it will need to be removed such as lower abdominal skin (tummy tuck/abdominoplasty), breast skin (breast lift), arm skin (brachioplasty).  Overall you need a full assessment, but simple liposuction alone will not tighten skin and needs a combination of various methods -- fat removal, skin tightening, defining, fat grafting, skin removal -- to get the best in body contouring and body sculpting.  Dr. Emer.

Lipedema is fibrotic Subcutaneous Adipose Tissue disease. It has a characteristic history that includes bilateral pain and leg swelling. It needs to be diagnosed with a careful physical exam and exclusion of other causes. No one can properly diagnose lipedema from just the photos. It is controversial whether lipedema can be diagnosed without symptoms, but I believe it can be. It is certainly possible that you have lipedema but I or any expert can not properly know without a full evaluation. Treatment of lipedema should be comprehensive and include an anti-inflammatory diet and compression. Lipedema Reduction Surgery is effective at reducing pain, and tenderness and improving mobility for women with lipedema. Lipedema Reduction Surgery can also improve body shape, but that is a secondary goal. Wishing you the best of health

Based on your pictures I don’t believe you have lymphedema. If you do it it’s a very mild version.This is a poorly understood condition. There is no test, understanding of underlying ideology or treatment other than Liposuction.Lower extremity liposuction is tricky and prone to come toward irregularities unless done with someone very talented and on someone who has tight skin.Skin laxity and cellulite ate both made worse by Liposuction.Best, Mats Hagstrom MD

A consultation with a board certified plastic surgeon is encouraged. This may be corrected using high defintion VASER liposuction. The Gold Standard for superior liposuction results requires use of the advanced technology of ultrasound assisted VASER liposuction. As an official trainer of VASER liposuction, I perform full body liposuction cases every week. VASER liposuction has been the only modality that has consistently resulted in outstanding liposuction outcomes. VASER liposuction ensures a smooth contour regardless of degree of excess fat by virtue of being able to remove any and all remaining fat comprehensively and uniformly. If skin redundancy is observed, Renuvion technology can be simultaneously applied to tighten your skin to optimize your overall contour outcome. A Skype or FaceTime consultation with a VASER specialist will help you get an accurate recommendation and pricing.
