According to Mayo Clinic, gastroparesis is a condition in which the muscles inside of the stomach do not function normally. Patients with gastroparesis may have issues with digestion and absorption of nutrients.
In a normal digestive system, food enters the stomach and is propelled forward throughout the digestive tract due to strong muscular contractions. However, in patients with gastroparesis, the walls of the stomach cannot contract normally and push food into the small intestine, according to Mayo Clinic. These patients may have difficulty emptying their stomach properly and can experience nausea, vomiting and extreme blood sugar fluctuations. There is no cure for the condition, but medications and dietary changes help to improve symptoms.
