Age — constipation is more common in older adults2. Gender — constipation occurs more frequently in women3. Low intake of fiber in the diet can cause constipation — Insoluble fiber cannot be digested by the body and adds bulk to the stools. This eases the passage of fecal material through the digestive tract. Soluble fiber retains water making stools softer.4. Low intake of fluids (dehydration) will lead to hard stools and difficulty to pass them.5. Less physical activity — people who exercise daily are less likely to have constipation.
Other risk factors for constipation include conditions such as:1. Diabetes mellitus2. Thyroid disorders (like hypothyroidism)3. Pregnancy4. Low levels of potassium (hypokalemia) or high levels of calcium in blood (hypercalcemia)5. Insufficient production of pituitary hormones6. Tumor of the adrenal gland7.

CT scan or MRI of the colon (large intestine) to check the length and width of the colon or any lesion that may cause obstruction.3. Barium enema study is an imaging study that uses x-rays along with an enema (containing barium) to detect abnormalities inside the colon. The contrast solution containing barium is injected into the rectum. Barium enema produces better images as compared to other imaging studies.4. Colonic transit time may be measured to evaluate the time taken by food to travel through the colon.5.
