Gastroparesis
A condition in which the stomach empties too slowly even though there is no blockage. Food lingers, causing nausea, vomiting, feeling full very quickly, bloating and upper-abdominal discomfort. Diabetes is a common cause, and it is managed with diet, medication to aid emptying, and blood-sugar control.
What it is
Gastroparesis means partial paralysis of the stomach — the muscular contractions that normally grind food and push it into the small intestine are weakened or poorly coordinated, so the stomach empties too slowly, despite there being no physical obstruction. Food sits in the stomach longer than it should, which causes nausea, vomiting (sometimes of food eaten hours earlier), feeling full after only a few bites (early satiety), bloating, and upper-abdominal discomfort. Because emptying is unpredictable, it can make blood-sugar control difficult in people with diabetes, and it can lead to poor nutrition and weight loss. The commonest identifiable cause is long-standing diabetes, which can damage the nerves controlling the stomach; other causes include previous stomach or oesophageal surgery, certain neurological conditions, and some medications that slow the gut, while in many people no cause is found (idiopathic). It is diagnosed after excluding a blockage, usually with a gastric emptying study that measures how quickly a labelled meal leaves the stomach. Management combines dietary changes (smaller, lower-fat, lower-fibre meals), medications that stimulate stomach emptying or control nausea, and, in people with diabetes, tighter blood-sugar control.
Key lab markers
- No blood test diagnoses it — diagnosis is by a gastric emptying study after excluding obstruction.
- HbA1c and glucose — important, as diabetes is a common cause and gastroparesis worsens sugar control.
- Blood count and nutritional markers — to assess the impact of poor intake.
- Endoscopy — often done first to rule out a physical blockage.
Symptoms
- Nausea and vomiting, sometimes of undigested food
- Feeling full after only a small amount of food (early satiety)
- Bloating and upper-abdominal discomfort
- Heartburn or reflux
- Loss of appetite and weight loss
- Erratic blood-sugar levels in people with diabetes

When to discuss with a doctor
Gastroparesis should be considered when nausea, vomiting, early satiety and bloating are persistent, particularly in someone with long-standing diabetes or after upper-gut surgery. See a doctor if these symptoms are ongoing, and seek prompt care if you cannot keep food or fluids down, are losing weight, show signs of dehydration, or (with diabetes) have blood sugars that have become very hard to control. Diagnosis first rules out a blockage, then confirms slow emptying with a gastric emptying study. Management focuses on diet, medications to help emptying and settle nausea, and — for people with diabetes — improving blood-sugar control, which can itself help the stomach. Mediora.AI can show glucose and HbA1c alongside your symptom pattern to highlight the diabetes link that so often underlies gastroparesis; the diagnosis and treatment belong with your doctor.
