6. Feeling full after eating very little

If you usually feel full too soon or after eating less than usual, get checked by your health care provider. You might have this feeling, known as early satiety, along with nausea, vomiting, bloating or weight loss. If so, be sure to tell your health care provider about these symptoms as well.

Possible causes of early satiety include gastroesophageal reflux disease, commonly known as GERD, and peptic ulcers. In some cases, a more serious problem — such as stomach cancer — could be a factor.
