Final answer:
Tom is at risk of constipation due to a low-fiber diet, inadequate hydration, physical inactivity, certain medications, and possible medical conditions. Increasing fiber intake, staying hydrated, and being physically active can help reduce this risk.
Step-by-step explanation:
Several factors place Tom at risk of constipation, which can be attributed to both lifestyle choices and physiological issues. A lack of fiber in the diet is a significant risk factor as fiber helps to bulk up stools and promotes regular bowel movements. Additionally, inadequate hydration can lead to harder stools that are difficult to pass. Physical inactivity also contributes to a sluggish digestive system, potentially resulting in constipation. Certain medications, such as opioid pain relievers, and medical conditions like hypothyroidism or irritable bowel syndrome, can also increase the risk of constipation. Addressing these factors through dietary changes, increased physical activity, and appropriate medical management can help alleviate the issue.
