The problem of excess sweating can be because of multiple reasons like hormone problem, other medications, some associated internal disease, anxiety or it can also be constitutional. Also need to know which part of the body is involved. There are certain tablets and lotions that can give improvement in this problem of excessive sweating. For a longer duration of relief you can also get botox injections over the area so that it decreases the sweat secretion for upto 6 months just by a single sitting of injection. Please get the condition properly assessed and evaluated before starting treatment. You can consult with me online for more information. Hope this is helpful.
