Symptoms of gastroparesis can vary from person to person, ranging from mild or severe. Some people may have most or even all of the symptoms of gastroparesis, while others may have just a few.
The most common symptoms of gastroparesis include:
- Nausea
- Vomiting of undigested food (may even be many hours after a meal)
- Feeling full after only eating a few bites
Other symptoms of gastroparesis include:
- Heartburn
- Abdominal bloating
- Abdominal pain
- Erratic blood glucose levels
- Lack of appetite
People with severe cases can sometimes experience unintentional weight loss. This can be due to a poor absorption of food, which can lead to nutritional deficiencies.
Gastroparesis-related vomiting usually occurs after meals; however, with severe gastroparesis, vomiting may occur without eating due simply to the accumulation of secretions in the stomach.
