We aimed to investigate the clinical features, precipitating factors, bowel habits, bothersome symptoms and treatment strategies of individuals in China with self-reported constipation.

An internet-based survey was conducted in China. The participants had self-reported chronic constipation (≥1 symptoms including straining, hard stools, time-consuming defecation, sensations of incomplete evacuation and anorectal blockage, using manual assistance, and fewer than three defecations per week, for over 6 months). Data on their sex, age and occupation, precipitating factors, bowel habit, main symptoms and treatment options were collected.

Overall, 6318 participants fulfilled the inclusion criteria for chronic constipation. More women (54.6%, n = 3450) than men reported constipation. The most common age group for constipation was 31 to 40 years (40.0%, n = 2520) and the most common occupation was office workers (43.6%, n = 2754). Disordered eating routines, consuming spicy food, and failure to defecate in time were the most common factors associated with constipation. Overall, 76.0% (n = 4804) participants did not defecate in the morning; 56.2% (n = 3548) spent 6 to 15 minutes in defecating. The most prevalent symptom was straining (39.4%, n = 2489). For preferred treatment options, 81.7% (n = 5160) selected changes in their lifestyle and diet, 51.1% (n = 3229) selected using traditional Chinese medicine, and 25.2% (n = 1590) selected using laxatives.

Constipation rates were higher in women, people aged 31 to 40 years old, and those working in offices. Having eating disorders, eating spicy food and withholding stools were the most common precipitating factors. Straining was the most prevalent symptom. Lifestyle changes were the most common action taken for managing constipation.
