I found once I got my blood sugar under control (hypoglycemic), my excessive sweating (at times, mainly when under stress) went away. I notice it now if I am under stress and my blood sugar is low.

Maxim Sensitive extra effective anti-perspirant wipes. 30 wipes per package. Only buy 1 package at a time, because last package I bought lasted 7 months, and there is an expiration date. Buy at http://www.maxim.com. I think the only way to get these is to order on the internet.

This is what worked extremely well for me. This worked far better for me than Certain Dri. I only have to use one of these wipes every 6 or 7 days to almost stop sweating.
A drawback is they tell you to apply it only at bedtime.

Hyperhidrosis is caused due to malfunctioning of the sympathetic nervous system or disorders of the sweat glands.

Excessive Sweating has four major types:

Palmar Excessive Sweating (sweaty palms) is a condition marked by excessive perspiration of the palms beyond physiological necessity.

Axillary Excessive Sweating (sweaty underarms) involves extreme dripping sweat in the armpits with constant odour that is usually resistant to all deodorants.

Facial Excessive Sweating (facial sweating) is stimulated by slight increasing in temperature and humidity.

Plantar Excessive Sweating (sweaty feet) usually occurs in conjunction with hand excessive sweating as a result of an overactive sympathetic nervous system.

Fortunately, excessive sweating can be controlled by an effective surgical treatment known as Endoscopic Thoracic Sympathectomy (ETS). ControlExcessiveSweating specialise in ETS, which is a proven surgical technique that disrupts the sympathetic chain and reduces or eliminates excessive sweating

Excessive sweating effects many people around the world but treatments cost lots of money. But you yourself could minimise the problem.

To do this try going to your doctors and getting prescribed deodorant or even try deodorants specially for your condition such as mitchum, they may be more expensive but better in the long run.

Also wear the correct clothing loose cotton clothing is the best as it allows your skin to breath.
