not finished

________ (GERD) is a chronic digestive disorder that occurs when stomach acid or bile flows back into the esophagus, causing irritation and inflammation.

Gastroesophageal reflux disease

________ also stimulates the release of HCl by activating the parietal cells directly.

Acetylcholine

________ is a natural agent that forms a protective layer over the stomach lining.

Bismuth subsalicylate

________ proton pump inhibitors can be used to reduce gastric acid levels.

Antacids and

________ can cause side effects such as headache, dizziness, and diarrhea.

H2RA drugs

________ of gastric acid can lead to acid reflux and ulcers.

Excessive production

________ is a synthetic prostaglandin E1 analog.

Misoprostol

________ are used to eradicate H. pylori infection, while discontinuing NSAIDs is necessary to prevent further damage to the stomach lining.

Antibiotics

It is effective in reducing the ________- induced gastric ulcers by up to 70 %.

risk of NSAID

________ (H2RA) drugs are a class of medications that are used to treat gastrointestinal conditions such as gastroesophageal reflux disease (GERD), peptic ulcers, and gastritis.

Histamine2 Receptor Antagonist

They work by blocking ________ in the stomach, which reduces the production of stomach acid.

histamine receptors

________: Abnormal contractions of the esophagus can cause food and stomach acid to reflux into the esophagus.

Esophageal Motility Disorders

________ are erosions in the lining of the stomach or duodenum.

Peptic ulcers

________ is the most common cause of peptic ulcers.

Helicobacter pylori infection

________ (LES) Dysfunction: The LES is a ring of muscle that acts as a valve between the esophagus and stomach.

Lower Esophageal Sphincter

________ can also occur if the ulcer blocks the passage of food through the digestive tract.

Obstruction

________ are commonly used to relieve pain and inflammation but can cause damage to the stomach lining when used excessively or for prolonged periods.

NSAIDs

________ stimulates the release of histamine, which in turn activates the proton pump on the parietal cells, leading to the production of HCl.

Gastrin

________: Certain foods and drinks, such as fatty or spicy foods, alcohol, and caffeine, can trigger acid reflux.

Dietary Factors

________ is also used to reduce the production of stomach acid and promote healing of the ulcers.

Acid suppression therapy

________ work by inhibiting the proton pump in the parietal cells of the stomach, which reduces the production of gastric acid.

PPIs

________ is a bacterium that infects the stomach and small intestine, leading to inflammation and erosion of the stomach lining.

H pylori

________: Excess body weight can increase pressure on the stomach, causing acid reflux.

Obesity

________ Histamine- 2 Receptor Antagonist.

H2RA stands for

________ is a complex disorder that involves multiple factors, including LES dysfunction, hiatal hernia, delayed gastric emptying, esophageal motility disorders, obesity, dietary factors, and smoking.

GERD

________ is a viscous substance that protects the mucosal lining of the gastrointestinal tract.

Mucus

________ (PPIs) are a class of drugs that are commonly used to treat gastroesophageal reflux disease (GERD) and other acid- related disorders.

Proton pump inhibitors

________ is a natural substance that is produced by the body and helps to stimulate the production of stomach acid.

Histamine

________ is produced by the parietal cells in the stomach lining through a complex mechanism.

Gastric acid

The drugs inhibit the production of ________, which are essential for protecting the stomach lining from acid damage.

prostaglandins

________ by blocking histamine receptors in the stomach, which reduces the production of stomach acid.

H2RA drugs works

________ are medications that neutralize stomach acid, which helps to relieve symptoms of heartburn, indigestion, and acid reflux.

Antacids

________ are available in different strengths and dosages, and can be purchased over- the- counter or by prescription.

H2RA drugs

________ are characterized by erosions or open sores in the lining of the stomach or duodenum.

Peptic ulcers

________ irreversibly bind to the H+ /K+ ATPase enzyme, which is responsible for the final step in the production of gastric acid.

PPIs

________ is a synthetic agent that stimulates the production of mucus.
