Identification

• A physical checkup of the anus and the rectum helps in detecting hemorrhoids. If the results of the physical exam prove to be inconclusive, a light might be used to check the regions for abnormal swellings.
  
  

Sclerotherapy

• Sclerotherapy involves injecting chemicals into a vein to promote withering and drying up of the hemorrhoid tissues.
  
  

Time Frame

• Sclerotherapy sessions are generally held three to four times a week for nearly a month, with each session lasting 30 to 45 minutes.
  
  

Effects

• Blood clotting, infections and inflammation are possible complications of sclerotherapy when used to treat hemorrhoids.
  
  

Prevention/Solution

• A diet rich in fibers and drinking eight to 10 glasses of water a day are recommended by the Mayo Clinic to regulate bowel movements and prevent hemorrhoids.
