Why does flatulence smell particularly foul in cases of constipation?

Foul-smelling flatulence accompanied by constipation may be related to poor dietary habits and slowed intestinal motility. Regular consumption of spicy or irritating foods, coupled with insufficient intake of dietary fiber-rich foods, can reduce intestinal water content, leading to constipation. Frequent consumption of foods such as sweet potatoes and taro may increase intestinal gas production, thereby exacerbating symptoms. Additionally, lack of regular physical exercise and infrequent abdominal massage can further slow gastrointestinal motility, worsening associated discomfort.
