Gastroparesis: Signals From Your Stomach

At first, it was easy to dismiss.

A few bites into dinner and you already felt full. Then came the bloating. Some days brought nausea. Other days, a meal seemed to sit heavily in your stomach for hours. Eventually, you started eating less without meaning to. Maybe your clothes fit differently or the number on the scale began dropping.

You knew something wasn’t right, but putting a name to it was another matter.

For people living with gastroparesis, that uncertainty can be part of the journey. Now is as good a time as ever to talk about a digestive condition that can turn something as ordinary as eating into a daily challenge. Based on how people describe living with gastroparesis, we wanted to let you know that we understand the struggle–and the toll it can take on you.

Gastroparesis, also called delayed gastric emptying, occurs when the stomach empties food too slowly even though there is no physical blockage preventing food from moving forward. Symptoms can include nausea, vomiting, abdominal pain, bloating, poor appetite and feeling full shortly after beginning a meal.

Understanding those symptoms is often the first step toward finally getting answers.

When “I’m Just Not Hungry” Becomes Something More

Imagine that the symptoms continue.

You begin planning meals around how your stomach might react. A normal-sized dinner suddenly feels impossible. You find yourself saying, “I’m full,” after only a few bites. Perhaps you experience nausea after eating or occasionally vomit food that seems barely digested.

These are among the common gastroparesis symptoms, but symptoms alone cannot confirm the condition. Gastroparesis can resemble other digestive disorders, which is why a proper evaluation matters.

A gastroenterologist may begin with your medical history, symptoms, current medications and a physical exam. Testing may be needed to rule out an obstruction or another explanation for your symptoms.

One important question then needs to be answered: How quickly is food actually leaving your stomach?

According to the American College of Gastroenterology, scintigraphic gastric emptying of a solid meal over at least three hours is recommended for diagnosing gastroparesis. Four-hour gastric emptying studies are commonly used. A gastric emptying breath test may also be used in some patients.

Getting a Diagnosis Leads to Another Question: What Causes Gastroparesis?

Once you finally have a name for what you have been experiencing, the next question is often, “Why did this happen?”

There isn’t always a simple answer.

Diabetes is the most common known underlying cause of gastroparesis. Over time, diabetes can damage nerves, including the vagus nerve, which helps control the muscles involved in moving food from the stomach into the small intestine.

Damage to the vagus nerve following surgery involving the stomach, esophagus or small intestine can also contribute to gastroparesis. Other associated conditions include hypothyroidism, certain autoimmune diseases and neurological disorders such as Parkinson’s disease and multiple sclerosis. Post-viral cases may occur as well.

In many people, however, doctors cannot identify a specific underlying cause. This is known as idiopathic gastroparesis.

Medications are another important part of the conversation. Opioid pain medications and certain other drugs can slow gastric emptying, mimic gastroparesis symptoms or make existing gastroparesis worse. Your gastroenterologist should know about all prescription medications, over-the-counter medications and supplements you take.

Learning to Eat Differently, Not Simply Less

After diagnosis, the story shifts from “What’s wrong?” to “How do I live with this?”

For many people, one of the biggest adjustments involves food.

A gastroparesis diet isn’t simply about cutting calories or avoiding everything you enjoy. The goal is to make it easier for the stomach to process food while helping you get enough calories, nutrients and fluids.

The National Institute of Diabetes and Digestive and Kidney Diseases recommends that people with gastroparesis may benefit from five or six smaller meals rather than two or three large meals. Foods lower in fat and fiber are often easier to tolerate. Soft, well-cooked foods may also be recommended.

During periods when symptoms are more severe, liquids or foods that have been blended into small particles may be easier to manage.

What Are the Worst Foods for Gastroparesis?

Picture your plate differently than you did before your diagnosis.

A large salad might sound healthy, but its high fiber content could be difficult for a stomach that empties slowly. Fried or high-fat foods may also take longer to leave the stomach. Foods that are difficult to chew thoroughly can create additional challenges.

That’s why people with gastroparesis are commonly advised to limit foods and beverages high in fat or fiber, carbonated beverages and alcohol. Individual tolerance varies, however. A food that causes significant symptoms for one person may be better tolerated by another.

The goal isn’t to create an unnecessarily restrictive diet. It’s to find a way of eating that reduces symptoms while protecting your nutrition.

Working with a registered dietitian can be particularly helpful when weight loss or inadequate nutrition becomes a concern.

Does Gastroparesis Ever Go Away?

By this point in the journey, this may be the question you most want answered.

For many patients, gastroparesis is a chronic condition rather than one with a one-time fix. Treatment instead focuses on addressing an underlying cause when possible, improving stomach emptying, reducing symptoms and preventing problems such as dehydration, malnutrition and excessive weight loss.

If diabetes is contributing to gastroparesis, managing blood glucose is an important part of treatment because high blood glucose can further delay stomach emptying.

Depending on the patient, treatment may also involve medications that improve stomach muscle contractions or help control nausea and vomiting. The American College of Gastroenterology notes that a small-particle diet and certain medications may be considered as part of treatment. People with severe gastroparesis who cannot maintain adequate nutrition may require additional nutritional support or other interventions.

In terms of managing the conditions, what matters is how you develop an individualized treatment plan with your doctor. Once you’re evaluated, they will generally want to understand  the cause of  delayed emptying, how severe the symptoms are and how well you respond to treatment.

Moving From Questions to a Plan

Living with gastroparesis can mean changing the way you think about meals, symptoms and even social occasions built around food. But having a diagnosis can also replace some of the uncertainty with a plan.

If you’ve been dealing with unexplained nausea, vomiting, early fullness, bloating, abdominal discomfort or unintended weight loss, don’t assume you simply have to live with it.

By talking about gastroparesis, let it be a reminder to pay attention when your digestive system keeps telling you something isn’t right.

The gastroenterology specialists at Gastroenterology of the Rockies can evaluate persistent digestive symptoms and help determine whether gastroparesis or another GI condition could be responsible. Learn more about gastroparesis or request an appointment to discuss your symptoms.
