Hiatus hernia is a condition usually diagnosed in later stages due to the lack of symptoms and the initial symptoms very assembling to other digestive diseases. Hiatal hernia is most common in persons of 55 years and more but can theoretically occur at any age. It is caused by a weakening of the diaphragm hiatus (esophageal opening) allowing the upper part of he stomach to turn up into the chest cavity. This condition is known as hiatus hernia and is responsible for the occurrence of gastric reflux.
The late diagnose is caused by the absence of symptoms in the early stages; when the patient begins to accuse pains in the esophageal part of the abdomen, the condition is usually in an advanced stage. There are more pathological forms of hiatus hernia according to the apparition cause. During sliding hiatus hernia, the esophageal lower sphincter gets weaker and allows the upper stomach part to slide upwards through the diaphragmatic opening. This form is the most easy to indulge and the body usually heals it by itself.
One more complex form of hiatus hernia is the rolling or fixed one that occurs when the part of the stomach connecting with the esophagus gets inflamed and causes the protrusion of the upper gastric segment through the diaphragmatic opening. Severe symptoms and complications are related to this hiatus hernia type.
Along the most commonly encountered causes of hiatus hernia is the age of the patient, knowing that an age of 55 and above can directly lead to the occurrence of the condition. Also an increased pressure while coughing or an abnormal sitting position can trigger hiatus hernia as well as a genetically inherited weakness of the diaphragm and esophagus. Obesity and heavy weight lifting will also cause the occurrence of a hiatus hernia. Some particular foods are held responsible for hiatus hernia; such products are chocolate, spearmint and cigarettes. Hiatus hernia has proven to have a hereditary component as well.
The most frequent symptoms of the hiatus hernia, when they occur, are heartburns, chest pains as well as pains in the esophageal area and frequent attacks. Some persons with this type of hernia also suffer from gastro esophageal reflux might experience sudden vomiting and nausea. A loss of consciousness may occur due to a decreased blood supply to the stomach or a high pressure exercised on the heart. A feeling of incapacity of swallowing food may be present in hiatus hernia.
Symptoms Of Hiatus Hernia
According to scientific studies, the diaphragmatic opening where the esophagus connects to the stomach, acts as an additional sphincter and together with the lower esophagus sphincter prevents the stomach content from backing up into the esophagus. When a hiatus hernia occurs, the sphincter function is weakened and the gastro esophageal reflux disease manifests itself.
The gastro esophageal reflux is in fact manifested by retention of the acid gastric contents of the stomach in the superior part of the stomach making the reflux into the esophagus possible. When the actual hiatus hernia is present and acid contents get into the esophageal tube, permanent lesions of the esophageal mucosa appear leading to major symptoms of heartburn, chest pain and a persistent sensitivity to food. Hiatal hernia sufferers experience high grade heartburns after heavy meals and are forced to eat more often and smaller quantities in order to prevent the gastro esophageal reflux.
According to a clinical classification, there are two major types of hiatus hernia:
In case of a sliding hiatal hernia both gastro esophageal junction and upper part of the stomach get into the chest cavity due to the weakened muscular hiatuses, meaning the lower esophageal sphincter and the diaphragmatic hiatus.
The junction connecting the esophagus to the stomach can remain permanently into the chest cavity or only slide up during the food or liquid swallowing process. The actual explanation is the functional changes that take place during swallowing when the esophagus shortens due to its contraction and pulls on the stomach's upper part.
When the swallowing is completed, the gastro esophageal junction falls back down into the abdomen. The sliding type occupies about 90% of all cases of hiatus hernia.
The second type is the Para esophageal hernia and occurs when the gastro esophageal junction remains in its normal physiological position but the upper part of the stomach slides back into the chest cavity beside the esophagus. In this case, the hiatus hernia remains permanently inside the chest and can lead to major and dangerous complications. The most frequent complications of the Para esophageal hernia are incarceration and strangulation.
Incarceration is the numb and squeeze of the hernia. Strangulation is the evolution complication of an untreated hernia incarceration. The blood supply is interrupted and the tissues involved begin to die. In this case, immediate surgical intervention is necessary.
