Diet for Ulcerative Colitis and Hyperglycemia


My husband was diagnosed with ulcerative colitis in March of this year and has been taking Asacol and steroids.
As a result, he was found to have high blood sugar in July.
In August, due to disease exacerbation, he started on the immunosuppressant Imura, and yesterday his liver function tests showed elevated levels.
During this period, he was hospitalized for 17 days in April and May, and for 35 days in August and September.
I would like to know what dietary considerations he should be aware of.
What can he eat, and what should be avoided? Thank you.

Hello! Regarding ulcerative colitis, it is important to follow a light diet.
If you are still experiencing diarrhea, you may consider supplementing with glutamine to prevent intestinal villous atrophy and to increase protein intake, especially when liver enzyme levels are elevated, as high protein is needed to repair liver tissue.
Commercial glutamine formulations include Abbott's Ensure and other nutritional products.
Additionally, intravenous glutamine can be considered if oral intake is inadequate.

It is essential to manage high blood sugar levels first and avoid simple sugars in your diet, such as sweets and refined foods.
Pay attention to regular meal timing and portion control.
Besides avoiding overly processed, greasy, and salty foods, there are no specific dietary restrictions; the key is to control portion sizes.
I recommend consulting a dietitian at your hospital for personalized dietary advice tailored to your needs.
For your intestinal issues, please consult your primary physician or, if necessary, seek help from an endocrinologist to manage your blood sugar levels.
Wishing you good health.
This response is from Dietitian Tsai Hsiu-Wen at Nantou Hospital, Department of Health.

Managing ulcerative colitis (UC) alongside high blood sugar can be quite challenging, especially given the complexities of both conditions and the medications involved. Your husband’s situation, with the use of Asacol, steroids, and Imura, along with fluctuating liver function, requires careful dietary planning to help manage symptoms and maintain overall health.


Dietary Guidelines for Ulcerative Colitis
1. Focus on a Low-Fiber Diet During Flare-Ups: When experiencing a flare-up, it is often recommended to consume a low-fiber diet to reduce bowel movements and irritation. This includes avoiding whole grains, nuts, seeds, and raw fruits and vegetables. Instead, opt for well-cooked vegetables, white rice, and refined grains.

2. Stay Hydrated: Diarrhea can lead to dehydration, so it’s crucial to drink plenty of fluids. Water is the best choice, but electrolyte solutions can also be beneficial if diarrhea is severe.

3. Protein Intake: Since your husband is on steroids, which can lead to muscle loss, it’s important to ensure adequate protein intake. Lean meats, fish, eggs, and dairy products are good sources. If he has difficulty with solid foods, protein shakes or smoothies can be a good alternative.

4. Avoid Trigger Foods: Common irritants include spicy foods, caffeine, alcohol, and high-fat foods. It’s essential to monitor which foods exacerbate symptoms and avoid them.

5. Consider Probiotics: Some studies suggest that probiotics may help in managing UC symptoms. Foods like yogurt or supplements can be beneficial, but it’s best to consult with a healthcare provider before starting any new supplement.


Dietary Guidelines for High Blood Sugar
1. Limit Simple Carbohydrates: Foods high in sugar, such as sweets, sugary drinks, and white bread, can spike blood sugar levels. Instead, focus on complex carbohydrates that are digested more slowly, such as whole grains (if tolerated), legumes, and non-starchy vegetables.

2. Regular Meal Timing: Eating at regular intervals can help maintain stable blood sugar levels. Small, balanced meals that include protein, healthy fats, and fiber can help manage blood sugar spikes.

3. Healthy Fats: Incorporate sources of healthy fats, such as avocados, nuts, seeds, and olive oil. These can help improve satiety and may have a positive effect on blood sugar levels.

4. Monitor Portion Sizes: Keeping an eye on portion sizes is crucial for managing both UC and blood sugar levels. Using smaller plates and measuring servings can help control intake.

5. Consult a Dietitian: Given the complexity of managing both UC and high blood sugar, working with a registered dietitian who specializes in gastrointestinal disorders and diabetes can provide personalized dietary recommendations.


Additional Considerations
- Liver Function: Since liver function tests are elevated, it’s important to avoid alcohol and limit foods high in saturated fats. A diet rich in fruits, vegetables, and whole grains can support liver health.

- Medication Interactions: Be aware of how certain foods may interact with medications. For example, some foods can affect the absorption of certain medications, so it’s important to discuss any dietary changes with the healthcare provider.

- Regular Monitoring: Regularly check blood sugar levels and keep a food diary to identify any correlations between diet and symptoms. This can help in making informed dietary choices.

In conclusion, managing ulcerative colitis and high blood sugar requires a balanced approach that considers both conditions. A focus on low-fiber, nutrient-dense foods, regular meal timing, and careful monitoring of blood sugar levels can help in achieving better health outcomes. Always consult with healthcare professionals for tailored advice and to ensure that dietary changes align with medical treatment plans.
