Piles can give a feeling of pressure around your bottom. If you are a sufferer of piles also called haemorrhoids you may be prone to a feeling of pressure around the bottom, almost as if you feel like you want to open your bowels called tenesmus. This can be very uncomfortable and inconvenient, as you will most likely be constantly wondering where the toilet is when you are out and about. The pressure in your bum comes from your rectum. The rectum is the last few inches of your large intestine where the intestine straightens vertically and flows to your anus. There are other conditions that might give you the same feeling, such as constipation, which can be treated with over the counter remedies.
Many Americans have difficulty moving their bowels. Many things contribute to this problem, including diet and activity level. Other causes are unknown. The large bowel consists of the colon 5 feet long and the rectum 8 inches long. Many times the rectum is referred to as the opening where stool emerges, but that is actually the anus.
