Gastroparesis (delayed stomach emptying) is a disease state caused by partial paralysis of the stomach. The BMCC serves as an integrated gastroparesis treatment and resource center, and we offer a full array of diagnostic and therapeutic options.

Do I Have Gastroparesis?

Gastroparesis is manifested by symptoms such as nausea, vomiting, bloating, feeling full quickly after starting a meal, severe heartburn, and loss of appetite leading to weight loss. Diagnostic testing such as endoscopy (EGD), cat scans (CT) or a swallow study (UGI) may suggest gastroparesis and eliminate other possible causes for your symptoms. The diagnosis will then be confirmed using a nuclear medicine gastric emptying study.

There is currently no cure, but treatment for gastroparesis can be very effective*.

What Causes Gastroparesis?

The number one cause for gastroparesis is diabetes. Diabetes causes nerve damage to the stomach. Over time, this leads to paralysis and dysfunction. However, gastroparesis can be caused by a variety of other factors as well.

Post-Surgical Causes:

Non-Surgical Causes:

However, often gastroparesis is idiopathic. This means that no clear causation may be apparent even after thorough investigation.

What Are My Treatment Options For Gastroparesis?

Symptoms can often be controlled using a variety of methods. Often these gastroparesis treatment methods are most effective in combination*.

First line therapies:

When first-line non-surgical gastroparesis treatments are unable to successfully control symptoms, surgical interventions may be needed to treat refractory gastroparesis*:
