Adolescent with untreatable 'fish odor syndrome' shares poignant reality of the disorder
Navigating life with 'fish odor syndrome': Teen's poignant revelation sheds light on the challenges of living with this rare, untreatable condition.
A teen just tried to live like a normal kid, then reality hit him in the nose. He posted on Reddit with a blunt title, “I have a condition that makes me smell really bad (TMAU) ama,” and honestly, the way he describes it sounds exhausting, not dramatic.
For over three and a half years, trimethylaminuria, also called “fish odor syndrome,” has made his body produce a smell he cannot fully control. It gets tied to everyday stuff, like what he eats, because the compound his body struggles with comes from digestion of foods like fish, eggs, and certain legumes. And when your condition is tied to something people notice instantly, social life stops feeling simple, fast.
His AMA turns out to be more than a confession, it is a peek into how “untreatable” can feel when you are the one living it.

Teenager's Battle with Fish Odor Syndrome
A teenager recently shared his life-altering diagnosis, highlighting the immense challenges he encounters daily due to trimethylaminuria, also known as "fish odor syndrome." This condition, although unfamiliar to many, significantly impacts individuals, influencing their social interactions, relationships, and dietary decisions. Coping with a chronic illness like trimethylaminuria requires immense strength and resilience, shaping one's life in ways that are often overlooked by those who do not experience it firsthand.
He did not ease into it, the teen opened his r/AMA post with the plain truth that TMAU makes him smell “really bad,” and that sets the tone immediately.
Teen with TMAU Shares Struggle on Reddit AMA
The teenager took to Reddit, specifically the r/AMA (Ask Me Anything) forum, to share his experiences and answer questions about his life with this condition. In his post, he candidly described his struggle, stating, “I have a condition that makes me smell really bad (TMAU) ama.” He elaborated that he has been living with this condition for over three years, stating, “I've had this condition making me smell noticeably really bad (and I mean really bad) for the last 3 and a half years.
Ask me anything.” Trimethylaminuria is characterized by an inability to break down trimethylamine, a compound that is produced during the digestion of certain foods, particularly those rich in choline, such as fish, eggs, and certain legumes.
The condition can arise from genetic factors, but it can also be secondary to other health issues or dietary choices, making it difficult to diagnose and understand. The teenager’s experience highlights the significant impact that trimethylaminuria has on daily life.
While there is currently no cure for the condition, individuals are often advised to make dietary adjustments, manage stress levels, and sometimes use medications to alleviate symptoms, which can include foul-smelling body odor, breath, and urine. For this young man, living with a severe case of secondary trimethylaminuria has proven to be particularly challenging.
When asked about the effects of his condition on his relationships, he shared that he has found it difficult to maintain social connections.” This illustrates the constant mental burden that individuals with chronic conditions often carry, as they must navigate their health while trying to lead a normal life.
He further elaborated on the emotional toll of living with trimethylaminuria, noting, “On the day to day... I don’t have a lot of support and honestly, with this disease, after a while, your focus goes entirely to just not having people react badly to you so it doesn’t bother me as much as it used to.” This statement underscores the isolation that can accompany chronic illness, as individuals may feel misunderstood or unsupported by those around them.

Once he explained it has been going on for three and a half years, the whole situation stopped being a mystery and started sounding like a daily battle.

Teen's Journey to Diagnosis: Trimethylaminuria Discovery
The teenager also recounted his journey to diagnosis, revealing that he first noticed an unusual odor when he was around 14 years old. Initially attributing it to poor hygiene, he sought medical advice and was eventually diagnosed with trimethylaminuria.
He described the odor as reminiscent of “fish or poop,” a stark and distressing realization for any young person. His desire for greater awareness of the condition reflects a broader issue faced by many individuals with rare diseases: the need for increased public understanding and empathy.
The moment he tied the odor to digestion and foods like fish, eggs, and legumes, it became clear why even meals could feel like a minefield.
The implications of living with trimethylaminuria extend beyond personal discomfort; they can affect educational and professional opportunities as well. The teenager mentioned that there was a period when his condition, compounded by other health issues, made it challenging for him to attend work and school.
However, he expressed determination to overcome these obstacles, stating, “I’m back at it now.” This resilience is a testament to the strength that many individuals with chronic illnesses must cultivate in order to navigate their daily lives. Moreover, the social stigma associated with conditions like trimethylaminuria can lead to feelings of shame and embarrassment.
The teenager's experience illustrates how societal perceptions can exacerbate the challenges faced by those with rare metabolic disorders. Many people may not understand the nature of the condition, leading to misconceptions and potentially negative reactions from peers and even family members.
This lack of understanding can create a barrier to open communication and support, further isolating those affected. In addition to the personal struggles shared by the teenager, it is essential to consider the broader context of trimethylaminuria and similar conditions.
Challenges in Diagnosing Metabolic Disorders
Research indicates that metabolic disorders can often go undiagnosed or misdiagnosed, leading to prolonged suffering for individuals. The rarity of such conditions means that healthcare providers may not always be familiar with them, resulting in a lack of appropriate treatment options and support.
Furthermore, the psychological impact of living with a chronic condition cannot be overstated. Many individuals experience anxiety, depression, and a diminished quality of life as they grapple with the realities of their health.
And when he mentioned that there is currently no cure, you can feel how that changes everything from school days to family hangouts.

It highlights the need for healthcare systems to address not only the physical aspects of these conditions but also the emotional and psychological challenges that accompany them.
