What is Gastritis?

Gastritis is considered to be a set of conditions that cause inflammation of the stomach lining, whose main causes are bacterial infection by Helicobacter pylori, excessive intake of medications, and abuse of alcohol, tobacco, and coffee.

It is possible that this condition appears suddenly, which is considered acute gastritis, or it can appear progressively, being chronic gastritis.

If not diagnosed and treated promptly, gastritis can cause stomach ulcers and be a risk factor for developing stomach cancer. However, in most cases it does not usually cause serious problems and is reversed with the appropriate treatment. 


Although sometimes it does not have clear symptoms, the most common symptoms are:

  • Sourness and heartburn.
  • Tightness in the upper abdomen accompanied by a feeling of being full after eating even a small amount food.
  •  Nausea and vomiting.

If you experience any of these symptoms for more than seven consecutive days, see your doctor. 

Potential risks:

  • Helicobacter pylori infection: this bacteria is present in a high percentage of people and its high incidence is considered to be due to genetic factors and eating habits or addictions to tobacco or alcohol. 
  • Anxiety and stress: they are considered factors that can cause acute gastritis that, if left untreated, can become chronic. 
  • Medication abuse: excessive intake of painkillers can damage the stomach lining, leaving it at the mercy of stomach acids involved in digestion. 
  • Alcoholism and smoking: abuse of these substances damages the stomach lining. 
  • Autoimmune diseases and others: patients with type 1 diabetes and Hashimotos disease are prone to gastritis, as are those with parasitosis, AIDS and Crohns disease.
  • Seniors: people in this stage of life are at greater risk of suffering from it due to the natural weakening of the stomach lining .

Diagnosis and treatment

After analyzing your symptoms and clinical history, your doctor will order a series of tests to confirm the diagnosis and rule out other conditions that could contribute to your discomfort.

The most common tests include:

  • Blood, stool, or breath test to check for Helicobacter pylori infection. 
  • Endoscopy to observe the digestive tract and take a tissue biopsy to analyze in the laboratory. 
  • Abdominal X-rays.

The treatment to be followed is established according to the direct cause of gastritis, but usually includes the following:

  • Antibiotics: if the cause is Helicobacter pylori infection, you will be prescribed several antibiotics since it is usually a bacteria resistant to various drugs. 
  • Antacids: they block acid production, helping damaged tissue to heal. 
  • Immediate-acting antacids: they quickly alkalinize stomach acid, relieving discomfort, but do not attack the direct cause.
