When you’re constipated, your body is not able to get rid of waste (carbon dioxide, water, and other, possibly harmful, substances) like it needs to. Having it every once in a while is common, but if you’re dealing with symptoms for more than 2-3 months, your constipation is chronic. And that raises your chance of having complications:
The veins around your rectum and anus swell. These swollen veins are called hemoroids or piles.
Anal Fissures :
Passing hard stools or straining to pass stools can tear the tissue around your anus. These tears are anal fissures. They cause itching, pain, and bleeding.
When you can’t get stool out of your body, it can start to stick together in your intestines. The hardened mass gets stuck and causes a blockage. The squeezing your colon normally uses to push stool out of your body can’t move it because it’s too large and hard.
It can cause pain and vomiting. You may even have to go to the emergency room for treatment. Children and older adults are more likely to have fecal impaction.
