A hiatal hernia or hiatus hernia is a condition when a part of your stomach squeezes up into the chest area through the diaphragm. The diaphragm is a large flat muscle separating the abdomen cavity and chest area. This muscle helps us breathing. In anyone have hiatal hernia his/her stomach will be pushed up to the diaphragm.
Why hiatal hernia happens?
The exact cause of hernia is not known. Most the time weakness of the diaphragm is blamable. How the diaphragm gets weaken? Diaphragm get weaker with age. It is developed in older ages, mostly after 50 years. Around 60 percent of the people get affected by hiatus hernia within age 60 years.
Types of hiatal hernia
There are three types of hiatus hernia:
- Sliding hernia (Type-1 hernia).
- Para esophageal herian (PEH) or rolling hernia (Type-2 hernia).
- Mix Hiatal hernia (Combined sliding and rolling) or (Type-3 hernia).
Also another type of hernia is declared in some taxonomy named type-4 hiatal hernia.
Type-1 hernia is most common. Most of the cases of hiatus hernia around 80% is type-1. It occurs when the esophagus and the stomach junction protrude up through the hitus opening in the diaphragm in the chest area. In some cases the herniated portion can slide back into and out of the chest.
In case of type-2 hernia or rolling hernia the stomach bulges into the chest out of the weakest part of the diaphragm. The esophagus and the stomach junction stays down within the abdomen and the fundus (upper part of the stomach) bugles up. Also in this case the hernia remains in one place and sitting next to the food tube (esophagus). It does not move in or out when patient swallow.
Symptoms of hiatal hernia
In most of the cases the hiatus hernia shows no specific symptoms. It gets treated with other disease. In case of hernia your stomach acid got the chance of flowing back to the esophagus. So most of the time it shows gastroesophageal reflux disease (GERD) symptoms. This is in case of large hernia. If your hernia is small, it will remain potential. That will show no symptoms. So symptoms of hiatus hernia will be like the following:
- Heartburn or chest pain.
- Sore throat.
- Difficulty swallowing (dysphagia).
