Chronic idiopathic constipation (CIC) is a form of long-term constipation without an identifiable medical cause. It's also called functional constipation and is coded in the ICD-10 system as K59.01.
CIC is diagnosed through patient history, symptom evaluation, and exclusion of other causes. Your gastroenterologist may order tests such as a colon transit study, anorectal manometry, or a colonoscopy to rule out structural or neurological disorders.
The ICD-10 code for chronic idiopathic constipation is K59.01. This code is used in medical records and insurance documentation to classify your condition.
Common symptoms include fewer than three bowel movements per week, hard or lumpy stools, straining during bowel movements, a sensation of incomplete evacuation, bloating, gas, and abdominal discomfort.
The exact cause is often unknown. Contributing factors may include a low-fiber diet, inadequate fluid intake, sedentary lifestyle, habitual stool withholding, and certain medications (e.g., opioids or some antidepressants).
Treatment typically begins with lifestyle changes: increasing dietary fiber, drinking 6-8 cups of water daily, and regular physical activity. Over-the-counter remedies like psyllium or stool softeners can help, and prescription drugs (linaclotide, lubiprostone, prucalopride) may be recommended if needed.
For patients who don't respond to basic measures, pelvic floor therapy and biofeedback can improve muscle coordination. Specialized tests (colon transit studies, anorectal function tests) guide further treatment plans.
Yes. Many patients benefit from natural approaches such as fiber-rich foods (fruits, vegetables, whole grains), adequate hydration, and daily walking. These form the foundation of long-term management.
Some individuals notice relief within a week of starting changes, while others may require several weeks or months of combined lifestyle and medical therapies. Your gastroenterologist will monitor progress and adjust your plan as needed.
If you've tried dietary modifications and over-the-counter remedies for four weeks without relief, or if you experience alarming symptoms such as rectal bleeding, unexplained weight loss, severe abdominal pain, or a sudden change in bowel habits, you should consult a gastroenterologist promptly.
