CoolSculpting is not recommended to treat on or around a hernia. A hernia occurs when part of an internal structure bulges through a weakened area of the body cavity. Hernias are caused by a combination of structural weakness (both hereditary or secondary) and increased pressure (such as heavy lifting, straining, etc.) A hiatal hernia occurs when part of the of the stomach bulges into the chest cavity through the hiatus, also known as the diaphragm opening. Treatment may cause increased pressure in the abdomen area, causing new hernia formation or exacerbate pre-existing hernia, which may require surgical repair. Therefore, CoolSculpting is not recommended.
