Numerous health conditions can cause early satiety, including peptic ulcers, tumors, gastroesophageal reflux disease, a problem with the nervous system and an obstruction. If the constant fullness lasts for several days or weeks and does not go away, a proper medical examination is needed to determine the exact cause of the problem. If a doctor suspects early satiety as the cause of the patient's stomach fullness, they will likely perform a series of tests including a complete blood count, stool testing, X-rays and an upper endoscopy.
If the patient has early satiety, the doctor may advise strict adherence to a liquid diet. It can also be beneficial to consume smaller and more frequent meals rather than trying to consume normal-sized meals. Eating a high-fat diet can cause early satiety to worsen, so patients are recommended to watch what they eat and try to consume less fat. Keeping a diet log may also be a helpful tool for patients to give to their doctor.Learn more about Health
