Clinical Information

In chronic constipation, the colon absorbs too much water from the stool, resulting in dry, hard stools that are difficult to pass. This can lead to discomfort, bloating, and abdominal pain. Chronic constipation may be due to various factors, including diet, lifestyle, medications, and underlying medical conditions.


The causes of chronic constipation can vary from person to person, but common factors include inadequate fiber intake, dehydration, lack of physical activity, certain medications (such as opioids), and medical conditions like irritable bowel syndrome (IBS) or thyroid disorders.


Some common symptoms of chronic constipation include infrequent bowel movements, straining during bowel movements, feeling of incomplete evacuation, abdominal discomfort or bloating, and hard or lumpy stools. If left untreated, chronic constipation can lead to complications such as hemorrhoids, anal fissures, or fecal impaction.


Diagnosing chronic constipation involves a thorough medical history, physical examination, and possibly diagnostic tests like blood tests, imaging studies (such as a colonoscopy), or tests to evaluate colonic transit time. Your healthcare provider will also consider your symptoms and bowel habits to determine the underlying cause of your constipation.


Treatment for chronic constipation often involves lifestyle modifications, such as increasing fiber intake, staying hydrated, exercising regularly, and establishing a regular bowel routine. In some cases, medications like laxatives or stool softeners may be prescribed to help alleviate symptoms. Severe cases of chronic constipation may require more intensive interventions, such as biofeedback therapy or surgery.


Chronic constipation is a common digestive disorder that can significantly impact quality of life. By understanding the causes, symptoms, diagnosis, and treatment options for this condition, individuals can effectively manage their symptoms and improve their overall gastrointestinal health.
