Erythematous Mucosa In The Antrum: 7 Day Treatment

Erythematous Mucosa in the Antrum

Erythematous mucosa in the antrum is called gastritis. The mucosa is a membrane that covers the interior of your stomach and intestines. Redness is referred to as erythematous. The inner lining of your digestive tract will be red if you have erythematous mucosa.

It’s important to note that erythematous mucosa is not a disease. It’s a sign of inflammation caused by an underlying disease or irritation, which has increased blood flow to the mucosa and turned it red.

Doctors use the term erythematous mucosa to describe what they see when they use a lighted scope inserted into your mouth or rectum to examine your digestive tract(This process is known as endoscopy). The disorder it causes is determined by which part of your digestive tract is affected:

Erythematous mucosa in the antrum(stomach) is termed Gastritis

Erythematous mucosa in the colon is termed Colitis

Erythematous mucosa in the rectum is termed Proctitis

Symptoms of Erythematous mucosa in the antrum(Gastritis)

Gastritis usually affects the entire stomach, but it may also affect only the antrum or lower portion of the stomach. Gastritis may be acute (short-term) or chronic (long-term).

Acute Gastritis

  • After eating, you can experience mild pain or a strong discomfort in the upper left side of your abdomen,
  • Nausea and vomiting,
  • Lack of appetite.
  • Heartburn, also known as indigestion, is a burning, dull pain.
  • You can vomit blood if the irritation is serious enough to cause an ulcer.
  • Acute gastritis, on the other hand, can often go unnoticed.

Chronic Gastritis

The majority of people with chronic gastritis still have no symptoms. However, B-12 deficiency can cause anemia because your stomach no longer secretes the molecule required to absorb B-12. If you’re anemic, you may feel exhausted, dizzy, and pale.

Diagnosis of Erythematous mucosa in the stomach(antrum)

Your doctor will review your personal and family medical history, conduct a comprehensive physical examination, and may prescribe one or more of the following tests to diagnose gastritis:

Endoscopy of the antrum

To examine the stomach lining, an endoscope, a thin tube with a tiny camera, is inserted through your mouth and down into your stomach. The doctor will look for signs of inflammation and can conduct a biopsy, which is a procedure that involves removing a small sample of tissue and sending it to a lab for examination.

Treatment of Gastritis (Erythematous mucosa in the antrum)

Several prescription and over-the-counter drugs that suppress stomach acid are available. Reduced stomach acid aids in the healing of inflammation. Your doctor can recommend or prescribe the following medications:

  • Antacids: These neutralize the acidity of the stomach and helps to reduce the pain fast.
  • PPI(proton pump inhibitors): These stops the production of HCl in the stomach. Despite OTC drugs they have certain side effects. So it’s better to use them under the doctor’s supervision and take supplementary calcium and Vit-D to avoid bone weakness.

Gastritis Summary

The mucosa is a mucus-based protective lining that lines the inside of your stomach. This lining protects your stomach from the powerful stomach acid that aids digestion. The mucosa gets inflamed when something hurts or weakens this protective coating, resulting in gastritis. The most common cause of gastritis is a form of bacteria called Helicobacter pylori (H. pylori).
