Causes of GERD

Let us understand what GERD means before running to the main topic, GERD causes. When you experience occasional acid reflux, it is very common. It occurs when you overeat, lye down just after eating or only eats particular foods.

If you experience recurrent acid reflux, which is well diagnosed to be GERD, it includes other causes along with risk factors and has an association with more serious complications.

Gastroesophageal reflux disease can easily affect people of all ages irrespective of the gender, and sometimes the causal of GERD is very difficult to know.5

Gerd causes

However, the cause related to gastroesophageal reflux disease (GERD) is not single. It mainly occurs when the gastric content dominates the esophageal defenses. This is followed by an injury to the tissues. You can easily observe GERD in 56-75% of individuals without any esophageal damage.

GERD mainly occurs when the LES barrier (Lower Esophageal Sphincter) weakens. The presence of occasional reflux presence is very common. It is normally without infrequent heartburn, in people who don’t have GERD. It is not necessary that people with histal hernia will have GERD and vice versa.

A hiatal hernia can be among GERD causes


Hiatal hernia is a medical condition. In this condition, the opening present in the diaphragm makes the top portion of the stomach to move up into the chest. This in result, the pressure in the esophageal sphincter lowers down and hence the risk of GERD increases.

When both the Lower Esophageal Sphincter and the diaphragm are connected well and functioning in good condition, reflux can even occur. After taking large meals the LES may relax which leads to the stomach’s upper part distention. Under this scenario, there is not enough pressure left at the LES to prevent the reflux. In some individuals, the LES becomes quite weak so it cannot put exertion to prevent the reflux. The amount of injury to the esophagus and the degree of severity of the GERD disorder directly depends on the following: –

  • Frequency of the reflux
  • Total stay time of the refluxed liquid in the esophagus
  • The amount of hydrochloric acid present.

When the sphincter muscles present in the bottom of the esophagus becomes weak or opens up when there is no requirement of it. This condition gives rise to GERD.

The following people are under the risk of having GERD: -

  • People who are overweight and have an excess weight which is due to the increased pressure exerted on the abdomen.
  • Pregnant woman, as they gain weight and hence exert pressure.
  • If you consume medications which come under the category of calcium channel blockers, asthma, sedatives, antihistamines along with anti-depressants.
  • If you are a chain-smoker and is in regular contact with smoke or second-hand smoke.
