Axillary hyperhidrosis laser surgery


Hello, I underwent laser lipolysis surgery for the treatment of axillary osmidrosis six months ago, but I still notice a slight odor.
How long does it typically take for the odor to completely disappear? Thank you!

Hello: Actually, surgery for body odor may not completely eliminate the smell, but rather reduce its severity.
I recommend using over-the-counter antiperspirants, which should help manage the body odor effectively.
Additionally, body odor tends to diminish with age, so it may not be a concern for you in a few years.
Wishing you all the best.

When it comes to laser treatment for underarm odor, particularly in the context of treating conditions like axillary hyperhidrosis (excessive sweating) or bromhidrosis (unpleasant body odor), it's important to understand both the procedure and the expected outcomes.

Laser treatments, such as laser lipolysis or laser sweat gland ablation, are designed to target the sweat glands in the underarm area. These procedures can significantly reduce the number of active sweat glands, which in turn can help decrease the amount of sweat produced and, consequently, the odor associated with it. However, it is essential to note that while many patients experience a significant reduction in odor and sweating after the procedure, complete elimination of odor may not always be guaranteed.

In your case, having undergone the procedure six months ago and still noticing some residual odor, there are several factors to consider:
1. Healing Time: After laser treatment, the body needs time to heal and adjust. While many patients notice improvements within weeks, it can take several months for the full effects to manifest. The healing process can vary significantly from person to person based on individual physiology, the extent of the procedure, and adherence to post-operative care instructions.

2. Residual Sweat Glands: It's possible that not all sweat glands were completely targeted during the procedure. Some individuals may have a higher density of sweat glands, which can lead to persistent odor even after treatment. Additionally, if the remaining glands are still active, they may continue to produce sweat, which can contribute to odor.

3. Hygiene and Lifestyle Factors: Personal hygiene plays a crucial role in managing body odor. Factors such as diet, stress levels, and overall health can influence how your body produces sweat and odor. For instance, certain foods, medications, or hormonal changes can exacerbate sweating and odor.

4. Follow-Up Treatments: If you are still experiencing odor after six months, it may be beneficial to consult with your healthcare provider or the specialist who performed the procedure. They can assess your situation and determine whether additional treatments or interventions are necessary. This could include further laser treatments, alternative procedures, or even non-invasive options like Botox injections, which can temporarily block the nerves that trigger sweating.

5. Expectations: It is essential to have realistic expectations regarding the outcomes of laser treatments. While many patients do achieve significant improvements, complete eradication of odor may not be feasible for everyone. Continuous follow-up and open communication with your healthcare provider can help manage expectations and explore additional options if necessary.

In summary, while laser treatment for underarm odor can be effective, individual results can vary. If you are still experiencing odor after six months, it is advisable to discuss your concerns with your healthcare provider. They can provide personalized recommendations based on your specific situation and help you explore further treatment options if needed.
