Flashcards

What is a hiatal hernia?

A condition where a portion of the stomach protrudes through the esophageal hiatus (an opening in the diaphragm) into the chest cavity.

What causes a hiatal hernia?

The primary cause of a hiatal hernia is weakening of the diaphragm muscle at the site of the esophageal hiatus.

What factors can worsen hiatal hernias?

Factors like pregnancy, obesity, chronic coughing, and heavy lifting increase abdominal pressure and can worsen hiatal hernias.

What is a sliding hiatal hernia? (Type 1)

The most common type of hiatal hernia, where the gastroesophageal junction and a portion of the stomach slide up into the chest cavity.

What is a paraesophageal hiatal hernia (Type 2)?

This type of hiatal hernia involves the herniation of the greater curvature of the stomach through a secondary opening in the diaphragm. The gastroesophageal junction remains in its normal position.

What is a mixed hiatal hernia (Type 3)?

A combination of a sliding and paraesophageal hiatal hernia. Part of the stomach herniates next to the esophagus, while the gastroesophageal junction moves above the diaphragm

Is hiatal hernia contagious?

Hiatal hernia is not contagious. It is caused by anatomical or structural changes in the diaphragm and can be present at birth (congenital).

What are some consequences of a hiatal hernia?

The lower esophageal sphincter (LES) loses its ability to close properly, which can lead to gastroesophageal reflux disease (GERD).

Obesity and Hiatal Hernia

Excess weight in the abdomen puts pressure on the stomach, pushing it through the opening in the diaphragm.

Heavy Lifting and Hiatal Hernia

Activities like lifting heavy objects increase pressure in the belly, straining the diaphragm and potentially causing a hernia.

Chronic Coughing and Hiatal Hernia

Persistent coughing strains the diaphragm, making it more likely to weaken and allow the stomach to move upwards.

Age and Hiatal Hernia

The diaphragm weakens over time, making it easier for the stomach to protrude through the opening.

Congenital Defects and Hiatal Hernia

Some people are born with a larger-than-normal opening in the diaphragm, making them more vulnerable to a hiatal hernia.

Genetics and Hiatal Hernia

Having a family history of hiatal hernia increases the chance of developing the condition, although it's not directly inherited.

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.
