Another change is fat buildup on the back of the shoulders and neck (sometimes called a "buffalo hump"). Fat on the back of the neck doesn't raise the risk of heart disease but can cause headaches and sometimes problems with breathing and sleeping.
Fat gain can make breasts bigger, which can cause back pain. Women seem more likely than men to experience greater fat gain in the breasts and the abdomen.
Fat accumulation also can make the face appear fuller.
