Study Notes

Hiatal Hernia

A hiatal hernia is a condition where part of the stomach protrudes through the esophageal hiatus (an opening in the diaphragm) into the thoracic cavity.

Causes

Weakening of the diaphragm: This is the primary cause, as the esophageal hiatus weakens, allowing abdominal organs to herniate into the chest cavity.
Increased abdominal pressure: Factors like pregnancy, obesity, chronic coughing, and heavy lifting can force the stomach through the weakened area.

Pathophysiology

Sliding Hiatal Hernia (Type 1): The most common type, where the gastroesophageal junction and a portion of the stomach slide up into the thoracic cavity due to increased abdominal pressure and a weakened esophageal hiatus. This can lead to gastroesophageal reflux disease (GERD).
Paraesophageal Hiatal Hernia (Type 2): Less common but potentially more serious, involving part of the stomach herniating through a secondary opening in the diaphragm, while the gastroesophageal junction remains in its normal position. This can lead to gastric strangulation if the blood supply is cut off.
Mixed Hiatal Hernia (Type 3): A combination of sliding and paraesophageal hernias, where part of the stomach herniates next to the esophagus, and the gastroesophageal junction moves above the diaphragm.

Transmission

Hiatal hernia is a non-communicable condition caused by anatomical or structural changes in the diaphragm.
It can sometimes be congenital (present at birth) in some cases.

Risk Factors (Modifiable)

Obesity: Excess abdominal fat increases pressure, pushing the stomach upward.
Heavy Lifting/Straining: Activities that increase abdominal pressure.
Chronic Coughing: Conditions like COPD or chronic bronchitis.
Smoking: Weakens the diaphragm and affects connective tissue.
Pregnancy: Increased intra-abdominal pressure.

Risk Factors (Non-Modifiable)

Age: Risk increases with age as the diaphragm weakens.
Congenital Defects: Some individuals are born with larger-than-normal esophageal hiatus.
Genetics: Family history of hiatal hernias increases likelihood.
