People get hemorrhoids when they apply too much pressure to the veins in the anal area.
This pressure occurs due to several situations.
These include standing or sitting for prolonged periods, constipation or straining to pass stools during a bowel movement, excessive diarrhea, from heavy lifting or even pregnancy and childbirth.
Both internal or external hemorrhoids may bleed.
If you have bleeding hemorrhoids you may see bright red blood in your stools, on your toilet paper or in the toilet basin.
If your hemorrhoids have been bleeding for a long time you should consult a doctor immediately.
Always seek the care of a doctor if you notice large amounts of rectal bleeding along with dizziness or faintness.
In order to stop the flow of blood to the hemorrhoid and prevent bleeding you need to avoid straining when you are on the toilet.
  Straining puts unnecessary pressure on the sensitive blood vessels in your rectal area.
The increased pressure causes them to bulge and sometimes bleed.
Sitting or standing for a long periods may cause bleeding because when you sit or stand for too long you are building up pressure.
The more pressure, the more chance you will bleed.
If you normally sit a lot try to get up and walk around every 15 minutes or so.
If you are on your feet all day find a few minutes to sit down and put your feet up.
When you have bleeding hemorrhoids there are a few things you can do to stop the bleeding.
One is to wipe yourself with clean wet toilet paper.
Wetting the paper makes it softer and less abrasive.
Better yet, wipe yourself with pre-moistened wipes that you can buy at the pharmacy.
Pre-moistened wipes that contain witch hazel are great for bleeding hemorrhoids because the witch hazel stops the bleeding right away.
A warm bath will also help with the bleeding.
Sitting in warm water helps enlarge blood vessels.
This allows the flow of blood to move out of the hemorrhoid causing it to shrink.
Other natural treatments include creams, ointments & suppositories.
