Can Doctor Fish Really Help Treat Psoriasis Effectively? - Dermatology

I heard that doctor fish can help with psoriasis?


My dad has been suffering from psoriasis all over his body, and the treatments at the hospital haven't shown any improvement.
Instead, the medications have caused side effects that affect other organs.
I once saw on television that Turkey offers a treatment method involving "doctor fish" in the water, which eat the dead skin from patients and help alleviate their condition.
Is this true?

Hello, Suya: I personally have many reservations regarding this treatment method (doctor fish).
I recommend following the medical practices announced by the Department of Health for treatment.
Thank you for using "Taiwan e-Hospital," which cares about your health.

The concept of using "Doctor Fish," specifically the Garra rufa fish, for treating psoriasis has gained popularity in recent years, particularly due to its unique behavior of nibbling on dead skin. This practice, often referred to as fish therapy or ichthyotherapy, is primarily seen in spa settings where individuals with skin conditions, including psoriasis, immerse themselves in tanks filled with these fish. The fish feed on the dead skin cells, which can provide a temporary exfoliating effect and may lead to a reduction in the appearance of scales.

However, while this treatment might seem appealing and can provide some immediate relief, it is essential to approach it with caution. The clinical evidence supporting the effectiveness of Doctor Fish in treating psoriasis is limited. Most studies conducted on this subject are anecdotal or lack rigorous scientific methodology. The primary benefit observed is the mechanical removal of dead skin, which can lead to a temporary improvement in the skin's appearance. However, this does not address the underlying causes of psoriasis, which is a chronic autoimmune condition characterized by rapid skin cell turnover and inflammation.

Psoriasis is a complex disease influenced by genetic, environmental, and immunological factors. Traditional treatments often include topical therapies, phototherapy, and systemic medications that target the immune system. These treatments aim to reduce inflammation, slow down skin cell production, and alleviate symptoms. While some patients may experience side effects from medications, it is crucial to consult a healthcare professional to find a suitable treatment plan tailored to individual needs.

In the case of your father, if conventional treatments have not yielded satisfactory results and have led to adverse effects, it may be worthwhile to explore alternative therapies under the guidance of a dermatologist. Options such as biologic therapies, which target specific pathways in the immune response, have shown promise for many patients with moderate to severe psoriasis. These treatments can be more effective and have a different side effect profile compared to traditional systemic medications.

Moreover, lifestyle modifications, including stress management, dietary changes, and maintaining a healthy weight, can also play a significant role in managing psoriasis. Some patients find that certain dietary adjustments, such as reducing inflammation-promoting foods, can help improve their skin condition.

In conclusion, while Doctor Fish may provide a novel and enjoyable experience, it should not be relied upon as a primary treatment for psoriasis. The best course of action is to consult with a healthcare provider who can offer evidence-based treatments and support. It is essential to address psoriasis comprehensively, considering both medical and lifestyle factors to achieve the best possible outcomes for your father's condition.
