Does gaining fat make your nose bulbous?

Hello,Gaining fat does affect many areas of your body, but your nose is not one of them. A bulbous tip is usually from genetics. Hope this helps, Deepak Dugar, MDScarless Rhinoplasty ExpertBeverly Hills, CA 90210

Thank you for the question! The simple answer is no, gaining weight or losing weight would not affect the shape or size of your nose. The size and shape of your nose is determined by bone and cartilage. Rhinoplasty works by reshaping or repositioning your cartilage to make your nose less bulbous. 
An in-person exam with a board-certified plastic surgeon is the best way to assess your needs and obtain expert medical advice. Best of luck!
