I have always had horrible allergies, both seasonal and household.

The allergies are likely connected to several things that have gone awry in the body.  I would first consider multiple causes, primarily gut health.  It is amazing when the gut barrier breaks down the blood stream gets exposed to allergens in the gut, you can really create a lot of allergies, both to food and otherwise in the body. So by increasing gut health by first doing a nice healthy detoxification program with your anti-aging physician's assistance, there is also a wonderful book called Clean by Dr. Alejandro Junger, which describes a fantastic three week detox program, this may be sufficient to help cure your allergies. The bioidentical hormones can be helpful in just obtaining optimal health.  People do feel better.  I think it would depend on your other health issues whether it would stop your allergies or not because you would really have to treat the whole body and get everything in the best working order possible then the allergies usually decrease, but I do recommend:

1. Detoxification.
2. Improving gut health using supplementation such as probiotics, glutamine, etc., depending on your particular needs to help improve the integrity of the gut lining and then also the bioidentical hormone replacement to help balance any hormone deficiencies you may have.  
3. I would also look at your cortisol levels and treat that as necessary as well.
