Does eating sweet potatoes worsen diarrhea?

Diarrhea is commonly referred to as "having loose bowels." Generally, patients experiencing an acute episode of diarrhea should avoid eating sweet potatoes, as this may worsen the diarrhea and hinder recovery. If symptoms are severe, patients are advised to follow medical advice and take prescribed medications for treatment.

Sweet potato, commonly known as yam or kudzu, is a herbaceous plant grown annually, with its underground part being tuberous roots in round or oval shapes. Sweet potatoes contain various nutrients such as protein, calcium, potassium, vitamins A, C, and E, dietary fiber, and starch. In traditional Chinese medicine, sweet potato is considered sweet in taste and neutral in nature, and is believed to tonify the spleen, improve blood circulation, boost energy, promote fluid production, and help relieve constipation.

In general, patients suffering from diarrhea should not eat sweet potatoes. This is because sweet potatoes contain high levels of dietary fiber and starch, both of which are difficult to digest. Patients with diarrhea often have weakened gastrointestinal function, and consuming sweet potatoes increases the digestive burden, potentially leading to more frequent bowel movements and causing gastrointestinal discomfort such as abdominal pain and bloating. As this is detrimental to recovery, it is not recommended. For patients with severe diarrhea, medications such as loperamide hydrochloride capsules or racecadotril granules may be used under medical supervision.

Diarrhea may also result from other conditions such as viral enteritis, Crohn's disease, or ulcerative colitis. Patients should undergo diagnostic tests like X-rays and stool examinations to determine the underlying cause and receive appropriate treatment as directed by a physician. In daily life, patients should maintain a healthy diet—preferring light, balanced meals and regular eating habits—and engage in moderate physical activity to enhance gastrointestinal function.
