Gastroparesis is a chronic digestive disorder in which the stomach is unable to empty food normally. Instead of moving food efficiently into the small intestine, the stomach muscles become weak or uncoordinated, causing delayed gastric emptying. This leads to nausea, bloating, vomiting, abdominal pain, and poor nutrition — often severely impacting quality of life.
Gastroparesis affects thousands of people in the United States and is frequently misdiagnosed as acid reflux, IBS, or anxiety before the correct diagnosis is made.
What Causes Gastroparesis?
Gastroparesis occurs when the nerves or muscles of the stomach are damaged. The most common causes include:
· Diabetes (especially long-standing or poorly controlled)
· Prior stomach or esophageal surgery
· Vagus nerve injury
· Autoimmune disorders
· Neurologic diseases (Parkinson’s, MS)
· Medications (opioids, GLP-1 medications, antidepressants)
· Idiopathic gastroparesis (no identifiable cause — very common)
Common Gastroparesis Symptoms
Patients with gastroparesis often experience:
· Chronic nausea
· Vomiting of undigested food
· Feeling full after only a few bites
· Severe bloating
· Upper abdominal pain
· Acid reflux
· Weight loss or malnutrition
· Blood sugar instability (in diabetics)
These symptoms may come and go or worsen over time.
How Gastroparesis Is Diagnosed
The gold-standard test is a gastric emptying study, which measures how long food remains in the stomach. Other tests may include:
· Upper endoscopy
· CT scan
· SmartPill motility capsule
· Barium studies
Medical Treatment for Gastroparesis
Initial treatment focuses on improving stomach emptying and reducing symptoms.
Medications
· Metoclopramide (Reglan)
· Erythromycin
· Domperidone
· Anti-nausea medications
Unfortunately, medications often lose effectiveness over time or cause side effects.
Gastroparesis Diet
Dietary modification is one of the most important parts of treatment.
Patients are advised to eat:
· Small frequent meals
· Soft or liquid foods
· Low-fat foods
· Low-fiber foods
Avoid:
· Fatty meals
· Raw vegetables
· Fibrous fruits
· Carbonated drinks
Protein shakes, soups, and blended foods are often better tolerated.
Advanced Surgical & Endoscopic Treatments
When diet and medications fail, advanced procedures can dramatically improve symptoms.
G-POEM (Gastric Peroral Endoscopic Myotomy)
G-POEM is a minimally invasive endoscopic procedure that treats the underlying cause of gastroparesis — a tight pylorus (the valve at the bottom of the stomach).
How G-POEM Works:
Using an endoscope passed through the mouth:
· The pyloric muscle is carefully cut
· This allows food to empty normally into the intestine
· No external incisions
· Same-day or overnight stay
Benefits of G-POEM:
· No abdominal surgery
· High success rate (70–80%)
· Rapid symptom improvement
· Little to no scarring
· Short recovery time
G-POEM has become the preferred treatment worldwide for severe gastroparesis.
Gastric Stimulator (Gastric Pacemaker)
A gastric neurostimulator is a surgically implanted device that sends electrical pulses to the stomach to reduce nausea and vomiting.
Who Benefits:
· Patients with severe vomiting
· Those who failed medications
· Diabetic or idiopathic gastroparesis
While the stimulator does not improve stomach emptying, it often dramatically reduces nausea and vomiting.
Which Treatment Is Right for You?
| Treatment | Best For |
| Diet & meds | Mild to moderate disease |
| G-POEM | Severe gastroparesis with delayed emptying |
| Gastric Stimulator | Severe nausea & vomiting |
| Combination therapy | Advanced cases |
Many patients benefit from both G-POEM and a stimulator depending on their disease pattern.
There Is Hope for Gastroparesis
For years, patients were told “there is nothing that can be done.” That is no longer true.
Modern endoscopic procedures like G-POEM and advanced surgical therapies have revolutionized gastroparesis treatment. Patients who were once dependent on feeding tubes and IV nutrition are now returning to normal eating and normal lives.
When Should You See a Specialist?
You should see a motility or surgical specialist if:
· You are vomiting frequently
· You have lost weight
· Medications no longer work
· You cannot tolerate food
· You have diabetes with bloating and nausea
Early treatment leads to better outcomes.
Conclusion
Gastroparesis does not have to control your life. Advanced treatments like G-POEM and gastric stimulation have restored normal eating, weight, and quality of life for thousands of patients.
If you are struggling with chronic nausea, vomiting, bloating, early fullness, or weight loss, seeking care from experienced Gastroparesis Doctors near Atlanta can help determine which treatment—or combination—will give you the best long-term relief.
