Propionic acidemia is a rare genetic disorder that affects the body’s ability to break down certain amino acids and fatty acids. This condition causes the build-up of propionic acid in the blood and tissues, leading to a range of symptoms that can be life-threatening if left untreated.
One of the most noticeable symptoms of propionic acidemia is a strong, distinct odor that is often describd as resembling rotten fish or sour milk. This smell is caused by the build-up of propionic acid in the body, which can be released through the breath and skin.
For individuals with propionic acidemia, this odor can be pervasive and difficult to mask, even with frequent bathing and the use of deodorants and perfumes. The smell can be particularly strong in young children, who may not be able to communicate their discomfort or understand why others are avoiding them.
While the smell associated with propionic acidemia can be distressing, it is important to recognize that it is a symptom of a serious underlying medical condition. Individuals with propionic acidemia require ongoing medical management, including dietary restrictions and medication, to prevent the accumulation of propionic acid and other harmful substances in the body.
If you or someone you know is experiencing an unusual odor that cannot be explained by hygiene or environmental factors, it is important to seek medical attention. While propionic acidemia is rare, early diagnosis and treatment can be life-saving for individuals with this condition.

Early diagnosis and treatment are crucial for individuals with this condition, and medical management is necessary to prevent serious health complications.
What Does Propionic Acidemia Smell Like?
Propionic acidemia is a rare metabolic disorder that can cause a distinctive odor. The smell is often described as similar to that of sour milk, rotten eggs, or sweaty feet. This odor is caused by the accumulation of propionic acid in the body, which is a byproduct of the breakdown of certain amino acids and fats. The odor can be present in sweat, urine, and breath, and is often most noticeable durig times of illness, stress, or fasting. It is important to note that not all individuals with propionic acidemia will have a noticeable odor, and the severity of the odor can vary depending on the individual and the specific metabolic profile.
What Are The Symptoms Of Propionic Acidemia?
Propionic acidemia is a rare genetic disorder that affects the body’s ability to break down certain amino acids and fats. The symptoms of propionic acidemia may vary in severity, but they usually appear within the first few days or weeks of life.
Here are the most common symptoms of propionic acidemia that you should look for:
– Poor feeding
– Vomiting
– Loss of appetite
– Weak muscle tone (hypotonia)
– Lack of energy (lethargy)
These initial symptoms can progress to more seious medical problems, such as:
– Dehydration
– Breathing difficulties
– Low blood sugar (hypoglycemia)
– High levels of ammonia in the blood (hyperammonemia)
– Metabolic acidosis
– Heart abnormalities
– Seizures
– Coma
– Possibly death
If you suspect that your child may have propionic acidemia, it is important to seek medical attention immediately. Early diagnosis and treatment can help prevent serious complications and improve the long-term outlook for your child.
What Are The Two Forms Of Propionic Acidemia?
The two most commonly used terms for describing the condition are propionic acidemia and propionyl-CoA carboxylase deficiency. The former refers to the accumulation of propionic acid in the body due to the inability to break it down properly, while the latter denotes a genetic defect in the enzyme propionyl-CoA carboxylase, which is responsible for breaking down propionyl-CoA into methylmalonyl-CoA. Ketotic hyperglycinemia was an older term used to describe the condition before the underlying genetic cause was identified. the two forms of propionic acidemia are propionic acidemia and propionyl-CoA carboxylase deficiency.
Why Does Propionic Acidemia Cause Hyperammonemia?
Propionic acidemia causes hyperammonemia due to a dysfunction in the Krebs cycle. In normal conditions, the Krebs cycle is responsible for generating energy and producing glutamine precursors that are important for ammonia detoxification. However, in individuals with propionic acidemia, the Krebs cycle is disrupted, leading to a decrease in citric acid production and an increase in methylcitric acid. This, in turn, reduces the availability of glutamine precursors, leading to an inability to adequately detoxify ammonia. The accumulation of ammonia in the bloodstream can lead to hyperammonemia, which can have serious neurological consequences if left untreated.
Conclusion
Propionic acidemia is a rare genetic disorder that can cause a distinctive smell often described as similar to rotten fish. The smell is caused by the accumulation of propionic acid in the body due to the inability to break down certan amino acids and fats. This smell can be challenging to mask with traditional hygiene products, and it can be distressing for individuals with the condition and their families. Early diagnosis and management of propionic acidemia are crucial to prevent serious medical complications. If you or someone you know experiences symptoms such as poor feeding, vomiting, loss of appetite, hypotonia, and lethargy, it is essential to seek medical attention promptly.
