Can you please list effective and available hemorrhoids treatment?

Depends. Diet and fluids is the first choice, then numerous topical agents, rubber banding of internal hemorrhoids and surgical removal of hemorrhoids by numerous means including scalpel, laser, stapling, sclerosis. Please avoid the advertised hemorrhoid clinics in general as they are really rip-offs on both you and the insurance companies. See a colorectal surgeon!
Variable. It depends on size and location of the hemorrhoids. Internal banding in the office for smaller internal hemorrhoids. Surgical options are hemorrhoid removal or hemorrhoid stapling procedures for larger hemorrhoids that may be both internal and external hemorrhoids.
