People with diabetes often experience a complication called autonomic neuropathy, which may cause constipation. Intestinal nerve damage (gastroparesis) can inhibit the regularity of your digestive system. However, it may not be diabetes. It could be your diet or medications.
Narcotic analgesics, such as Tylenol with codeine or Darvon, can be constipating.
Some people become constipated while taking antidepressants or blood pressure
medications. Diet and exercise also play a role in digestive health. Try to
add more fiber to your meals, and make sure you’re getting enough water
and physical activity. Talk to both your doctor and your dietitian about constipation.
