Should patients with chronic pancreatitis follow a low-sugar diet?

In general, whether patients with chronic pancreatitis need a low-sugar diet depends on their blood glucose levels. Patients without abnormal blood glucose do not require a strict low-sugar diet; controlling total caloric intake is sufficient. However, those with elevated blood glucose or diabetes should adhere to a low-sugar diet. The details are as follows:

If pancreatic function is only mildly impaired in patients with chronic pancreatitis and insulin secretion remains unaffected, with blood glucose levels within the normal range, there is no need for strict sugar restriction in daily diet. It is sufficient to maintain a balanced diet, avoid excessive consumption of high-sugar snacks and desserts to prevent exceeding total calorie needs, which could lead to obesity and increased pancreatic burden. Natural sources of sugar such as fruits and whole grains can be consumed in moderation.

When chronic pancreatitis recurs over a long period, damaging the pancreatic islet cells and leading to insufficient insulin secretion, resulting in elevated blood glucose or even progression to diabetes, a strict low-sugar diet is necessary. Intake of refined sugars and sugar-sweetened beverages should be reduced to avoid significant blood glucose fluctuations. Additionally, foods with a low glycemic index—such as whole grains, legumes, and leafy vegetables—should be chosen to help stabilize blood glucose levels.

Dietary management for patients with chronic pancreatitis should primarily focus on being low-fat and easily digestible, with regular meal times and avoidance of overeating. Combined with moderate physical activity, this approach helps maintain pancreatic health and metabolic stability.
