Gastritis occurs when the lining of the stomach becomes inflamed after it’s been damaged. It’s a common condition with a wide range of causes. For most people, gastritis is not unplayful and improves cursorily if treated. But if not, it can end for years .

Symptoms of gastritis

many people with gastritis caused by a bacterial infection do not have any symptoms. In other cases, gastritis can cause :

Reading: Gastritis

  • indigestion
  • gnawing or burning stomach pain
  • feeling and being sick
  • feeling full after eating

If the digest lining has been worn away ( erosive gastritis ) and exposed to stomach acerb, symptoms may include pain, bleed or a digest ulcer. The symptoms of gastritis may come on suddenly and sternly ( acute gastritis ) or last a long time ( chronic gastritis ) .

When to see a GP

If you have indigestion and stomach pain, you can try treating this yourself with changes to your diet and life style, or with medicines you can get from a pharmacy, such as antacids. See a GP if :

  • you have indigestion symptoms lasting a week or longer, or it’s causing you severe pain or discomfort
  • you think it’s brought on by medicine you have been prescribed
  • you’re vomiting blood or have blood in your poo (your poo may appear black)

Stomach hurt and abdominal pain are not always a sign of gastritis. The pain could be caused by a wide-eyed range of other things, from trapped wind to excitable intestine syndrome ( IBS ) .

Diagnosing gastritis

A GP may recommend 1 or more of the pursuit tests :

  • a stool test – to check for infection or bleeding from the stomach
  • a breath test for Helicobacter pylori (H. pylori) infection – this involves drinking a glass of clear, tasteless liquid that contains radioactive carbon and blowing into a bag
  • an endoscopy – a flexible tube (endoscope) is passed down your throat and into your oesophagus and stomach to look for signs of inflammation
  • a barium swallow – you’re given some barium solution, which shows up clearly on X-rays as it passes through your digestive system

Possible causes of gastritis

Gastritis is normally caused by 1 of the follow :

  • an H. pylori bacterial infection
  • excessive use of cocaine or alcohol
  • smoking
  • regularly taking aspirin, ibuprofen or other painkillers classed as non-steroidal anti-inflammatory drugs (NSAIDs)
  • a stressful event – such as a bad injury or critical illness, or major surgery
  • less commonly, an autoimmune reaction – when the immune system mistakenly attacks the body’s own cells and tissues (in this case, the stomach lining)

H. pylori gastritis

many people become septic with H. pylori bacteria and do not realise it. These stomach infections are park and do not normally cause symptoms. But an H. pylorus infection can sometimes cause recurring bouts of indigestion, as the bacteria can cause inflammation of the abdomen line.

This screen of gastritis is more common in older historic period groups and is normally the cause of chronic ( persistent ) non-erosive cases. An H. pylorus stomach contagion is normally lifelong, unless it ‘s treated with eradication therapy .

Treating gastritis

treatment aims to reduce the sum of acid in the stomach to relieve symptoms, allowing the stomach lining to heal and to tackle any implicit in induce. You may be able to treat gastritis yourself, depending on the cause .

Easing symptoms

  • antacids – these over-the-counter medicines neutralise the acid in your stomach, which can provide rapid pain relief
  • histamine 2 (H2) blockers – these medicines decrease acid production and are available to buy from your pharmacist and on prescription
  • proton pump inhibitors (PPIs), such as omeprazole – these medicines decrease acid production even more effectively than H2 blockers

Some low-dose PPIs can be bought from your pharmacist without a prescription. You ‘ll need a prescription drug from a GP for stronger doses .

Treating H. pylori infection

If an H. pylorus infection is the cause of your gastritis, you ‘ll need to take a course of antibiotics alongside a proton pump inhibitor .

Things you can do to ease gastritis

If you think the cause of your gastritis is repeated function of NSAID painkillers, try switching to a unlike analgesic that ‘s not in the NSAID class, such as paracetamol. You may want to talk to a GP about this.

besides study :

  • eating smaller, more frequent meals
  • avoiding foods that can irritate the stomach, such as spicy, acidic or fried foods
  • avoiding or cutting down on alcohol
  • quitting smoking if you smoke
  • managing stress

Possible complications of gastritis

gastritis that lasts for a long fourth dimension can increase your risk of develop :

  • a stomach ulcer
  • polyps (small growths) in your stomach
  • tumours in your stomach, which may or may not be cancerous

Gastritis or gastroenteritis?

  • Gastroenteritis is inflammation (irritation) of the stomach and bowel, caused by an infection.
  • Gastritis is inflammation of the stomach lining specifically, and not always caused by infection.
