Constipation means a condition in which there is difficulty in emptying the bowels, usually associated with hardened faeces.
Constipation is a common digestive issue in which bowel movements are infrequent or difficult to pass.
It's considered a symptom of various health issues, rather than a disease in and of itself. "Normal" bowel habits differ between people. Some people may pass stool three times a day, while others may only have a bowel movement three times a week.
You're considered constipated if you have fewer than three bowel movements in a week. After this point, your stool may harden and become difficult or even painful to pass.

Symptoms of chronic constipation
• Passing fewer than three stools a week
• Having lumpy or hard stools
• Straining to have bowel movements
• Feeling as though there's a blockage in your rectum that prevents bowel movements
• Feeling as though you can't completely empty the stool from your rectum
• Needing help to empty your rectum, such as using your hands to press on your abdomen and using a finger to remove stool from your rectum

• unhealthy and irregular eating habits, or eating very small portions
• not visiting the toilet when the pressure arises
• leading a sedentary lifestyle
