Overview

Gastroesophageal reflux disease (GERD) is a long-term digestive problem in which stomach acid or contents flow back into the esophagus. Acid reflux occurs when stomach acid flows back up into the esophagus, irritating the lining and causing symptoms that don't go away. It is normal to have reflux from time to time, but GERD is diagnosed when symptoms happen often or cause problems. People of all ages can develop this condition, and it is often linked to their lifestyle. If acid exposure is not treated, it can hurt the lining of the esophagus over time and cause ulcers. Managing symptoms early on helps keep them under control and stops them from getting worse.

Symptoms
Heartburn, a burning sensation in the chest, is the most common symptom of GERD. It may get worse after meals or when you lie down. Other signs include vomiting sour fluid, trouble swallowing, a chronic cough, hoarseness, and a feeling of a lump in the throat. Some people experience chest pain or bloating, especially after eating a large meal.

Causes
When the lower esophageal sphincter, a muscle that prevents stomach contents from flowing back up, weakens or relaxes too much, it can cause GERD. Being overweight, eating too much, eating fatty or spicy foods, drinking too much caffeine, smoking, and drinking alcohol are all risk factors. Pregnancy, some medications, and a hiatal hernia can also make reflux happen more often.

Diagnosis
Symptoms and how well a treatment works are often used to make a diagnosis. Doctors might suggest an endoscopy to look for inflammation or damage to the lining of the esophagus. In cases that are hard to treat or last a long time, doctors may order additional tests, such as pH monitoring or esophageal motility studies.

Treatment
Medications and lifestyle changes are part of treatment. It is advised to avoid trigger foods, eat smaller meals, keep your weight in check, and not lie down right after eating. Doctors often prescribe drugs that reduce stomach acid or improve digestive function. In severe or resistant cases, surgical procedures to strengthen the lower oesophageal sphincter may be considered.

With the right care, GERD usually has a good outlook. Many people can control their symptoms by making lifestyle changes and taking medication. If you don't treat your GERD, it could get worse, so it's important to keep up with your treatment and follow up regularly.
