There are several causes of hyperammonemia, including:

• Genetic Disorders: Certain inherited conditions, such as urea cycle disorders, can impair the body’s ability to process ammonia.
• Liver Disease: Conditions like cirrhosis or hepatitis can hinder the liver’s function, resulting in ammonia buildup.
• Medications: Some drugs can interfere with ammonia metabolism, leading to elevated levels.
• Infections: Severe infections can increase protein breakdown, causing more ammonia to be produced.

Symptoms of Hyperammonemia

The symptoms of hyperammonemia can vary in severity and may include:

• Confusion or altered mental status
• Fatigue and lethargy
• Vomiting
• Seizures
• Coma in severe cases

If you or someone you know is experiencing these symptoms, it is crucial to seek medical attention promptly. Early diagnosis and treatment can significantly improve outcomes.

Ornithine Transcarbamylase Deficiency Explained

Ornithine transcarbamylase (OTC) deficiency is a specific type of urea cycle disorder that leads to hyperammonemia.
