Gastroparesis can cause several complications, such as:

  • Severe dehydration. Ongoing vomiting can cause dehydration.
  • Malnutrition. Poor appetite can mean you don't take in enough calories, or you may be unable absorb enough nutrients due to vomiting.
  • Undigested food that hardens and remains in your stomach. Undigested food in your stomach can harden into a solid mass called a bezoar. Bezoars can cause nausea and vomiting and may be life-threatening if they prevent food from passing into your small intestine.
  • Blood sugar fluctuations. Although gastroparesis doesn't cause diabetes, inconsistent passage of food into the small bowel can cause erratic changes in blood sugar levels, which make diabetes worse. In turn, poor control of blood sugar levels makes gastroparesis worse.
  • Decreased quality of life. Acute flare-up of symptoms can make it difficult to work.
