There are 3 solutions:
1: Wide excision surgery removing the infected sweat glands once and for all
I asked 1 of the private dermatologists who specialises in HS and he said this alone had a 90% cure rate and it's permanent!
2: Get an allergy test
If you're allergic to any of the foods, eliminate them from your diet. (If you aren't allergic to anything then this may not be the problem). Most people think nightshades are the problem but that isn't true for everyone, it's only true for that individual. You may be allergic to gluten, dairy etc and it could be just certain foods, so it's crucial to get an allergy test done to know for sure.
3: Laser hair removal where the hidradenitis occurs
This alone wouldn't work though I heard since the root of the problem here are the infected sweat glands, so you'd have to remove them 1st and then get laser hair done in the end.
Combine these 3 solutions and you might permanently be free of hidradenitis.
Here's a list of faq's from 1 of the plastic surgeon's website who specialises in HS
FAQ:
1. Is HS contagious?
The disease is not contagious.
2. Is HS affected by diet?
Some suffering from HS have said a change in diet helps, and many have tried the Paleo diet. However, restricting certain foods may affect people in different ways. Keeping a food diary to learn what works for you might be the best way to determine certain foods trigger an outbreak or worsening of symptoms.
3. How do you treat patients with multiple areas affected by HS?
We often stage treatment allowing one affected area to be surgically addressed and after a period of 8-12 weeks, address the other areas.
4. Does HS run in families?
In most cases, the cause of Hidradenitis Suppurativa is unknown. The condition probably results from a combination of genetic and environmental factors.
5. What percentages of patients are cured by surgery?
Wide excision with reconstruction of the affected areas affords the highest chance of cure, with our patients experiencing 90% cure.
6. When is surgery an appropriate treatment?
The decision to operate on those with HS depends on the condition of the affected areas. If there is an acute infection, the first step will be to address the infection with antibiotics as well as a first stage drainage. As the infection clears, a more definitive treatment will be necessary. In order to properly treat the HS in those areas, a wide excision needs to be performed to remove the disease bearing tissue followed by reconstruction using plastic surgery reconstructive techniques.
7. Do overweight individuals with HS get better once they lose weight?
When overweight patients who have HS lose weight, they seem to have fewer flare-ups. Losing excess body weight can make a difference.
8. Why does HS smell?
The odor comes from local infection of the apocrine glands. The odor is more pronounced when there is a flare.
9. Is there a prescription medicine used to treat HS?
There are many medications on the market that patients have used. The only group of medications I use in my patients is antibiotics in the setting of an infection. This is given to help treat the infection prior to definitive surgical treatment of the disease.
10. Will shaving make my HS worse?
This is a myth and not been shown to be an aggravating factor for HS.
Hope this helps cheers
