Overview

Gastroparesis is a condition in which the stomach empties more slowly than normal, even though there is no physical blockage. This happens when the stomach muscles or the nerves that control them do not function properly, causing food to remain in the stomach longer than it should. Symptoms can vary in severity, but with appropriate dietary adjustments, lifestyle changes, and medical therapy, many patients are able to achieve meaningful symptom control.

What Is Gastroparesis?

Gastroparesis is a condition in which the stomach is unable to move food into the small intestine normally, even though there is no mechanical blockage. The muscles of the stomach are weakened or do not work properly, causing food to stay in the stomach longer than it should.

Common Symptoms of Gastroparesis

• Feeling full soon after starting a meal or for a long time after eating
• Nausea and vomiting, especially of undigested food
• Bloating and excessive belching
• Upper abdominal pain
• Heartburn or acid reflux
• Poor appetite and weight loss
• Changes in blood sugar levels (especially in people with diabetes)

If you have severe pain, vomiting blood, or signs of dehydration, seek medical attention promptly.

What Causes Gastroparesis?

• Diabetes, especially when blood sugar is poorly controlled
• Surgery near the stomach or vagus nerve (the nerve that controls stomach muscles may become damaged and not function properly)
• Viral illnesses that can cause damage to the vagus nerve
• Medications that slow gastric motility (such as some pain or antidepressant medications)
• Neurologic or autoimmune conditions
• Many cases have no identifiable cause (idiopathic)

How Is Gastroparesis Diagnosed?

Common tests may include:

• Gastric emptying study (measures how quickly food leaves the stomach)
• Motility studies
• Imaging to check for blockages or other causes

Treatment Options for Gastroparesis

While there is no single cure for gastroparesis, symptoms can often be effectively managed with a thoughtful combination of dietary adjustments, lifestyle changes, and medical therapy.

Simple changes can make a meaningful difference in day-to-day symptoms:

• Eat smaller, more frequent meals rather than large portions
• Choose low-fat, low-fiber foods, as fat and fiber slow stomach emptying
• Opt for soft, blended, or puréed foods if solid foods are difficult to tolerate
• Remain upright after eating; light activity, such as a gentle walk, may help digestion
• Drink fluids between meals, rather than with large meals

These strategies can help reduce symptoms such as nausea, bloating, early fullness, and discomfort, and are often tailored to each individual’s tolerance and lifestyle. Your doctor may also recommend medications to help the stomach muscles contract, reduce nausea and vomiting, and improve blood sugar control if diabetes is a factor.

In more severe cases of gastroparesis, additional treatments may be considered. These can include implantable devices designed to help stimulate stomach muscles, minimally invasive procedures aimed at improving stomach emptying, or feeding support when needed. These options are reserved for select situations and are carefully tailored to each patient’s needs.

Gastroparesis is a chronic but manageable condition. With careful evaluation and an individualized treatment plan, many people are able to reduce symptoms, maintain nutrition, and improve quality of life over time.
