What Is Gastritis?
Gastritis is inflammation or irritation of the stomach lining that can occur suddenly or develop over time. Symptoms often include a burning sensation, discomfort, or nausea. If left untreated, gastritis may lead to ulcers or bleeding. The general ICD-10 code for this condition is K29.7.
Common Causes and Risk Factors
Infection with Helicobacter pylori bacteria
Regular use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin or ibuprofen
Heavy or chronic alcohol consumption
Ongoing physical or emotional stress and severe illness
Autoimmune disorders attacking stomach cells
Tobacco smoking
Signs and Symptoms
Burning pain or discomfort in the upper abdomen
Nausea or episodes of vomiting
Bloating or feeling full after small meals
Loss of appetite
Heartburn or general indigestion
Pain radiating to the mid-back in some cases
How Dr. Scott Diagnoses This Condition?
Dr. Scott uses a step-by-step approach:
Medical History and Exam
He reviews your epigastric pain-its onset, duration and triggers-along with symptoms like nausea or bloating. He'll ask about NSAID use, alcohol intake, stress levels and other risk factors, then perform a focused abdominal exam to check for tenderness or signs of complications.
Blood Tests
We order a complete blood count to look for anemia, check inflammatory markers and, when indicated, screen for H. pylori antibodies or other infectious causes.
Imaging Studies
Upper endoscopy (EGD): Provides direct visualization of the stomach lining and allows biopsy to confirm inflammation, ulcers or H. pylori.
Abdominal ultrasound: Used selectively to rule out gallbladder disease or other abdominal sources of pain.
Advanced Testing (if needed)
For persistent or unclear cases, we may perform a urea breath test or stool antigen test to confirm H. pylori, and review biopsy specimens to exclude rare conditions or malignancy.

Frequently Asked Questions
How long does gastritis last?
Mild cases often improve in a few days. Long-term or chronic gastritis may take weeks or months to fully resolve with treatment. Dr. Scott will tailor a plan to your needs.
What is the ICD-10 code for gastritis?
The general code for gastritis is K29.7, although specific subtypes (acute, chronic, with bleeding) have their own detailed codes.
Can gastritis cause back pain?
Yes. In some patients, the discomfort or burning in the upper abdomen can radiate to the middle of the back.
What foods should I eat?
Choose bland, easy-to-digest options like lean chicken, fish, rice, bananas, oatmeal, and yogurt. Avoid spicy, fried, acidic, or highly seasoned foods.
When should I see a doctor?
If you experience persistent abdominal pain, frequent vomiting, black or tarry stools, or unexplained weight loss, schedule an appointment with Dr. Scott promptly.
Is an endoscopy always needed?
No. Many mild cases can be diagnosed with history, bloodwork, and non-invasive tests. Endoscopy is reserved for severe, bleeding, or non-responsive cases.
Is gastritis contagious?
The inflammation itself isn't contagious, but H. pylori infection (a common cause) can spread through close contact or contaminated food and water.
