It may develop due to infection or irritation as well. Further, there are numerous bodily areas where fistulas might develop. They can appear anywhere, such as between the vagina and the rectum or between the gut and the epidermis.

Diet is a crucial component in fistula treatment. An appropriate and nutritious diet can treat fistula in its early stages. The size and sincerity of the diet would depend on the type and location of the fistula.

1. Pulses:  


Include moong dal, chickpeas, masoor dal, and soybean in the fistula patient’s diet. Pulses are high in fiber and protein. Hence, it aids in maintaining a healthy digestive system. In addition, the high fiber content keeps you full for a very long time.

2. Coconuts: 

Coconuts are fiber-rich and thicken the stool to promote regular bowel movements. On the other hand, coconut meat is rich in medium-chain fatty acids (MCFAs), a form of saturated fat that the body can digest far more quickly than animal fats, protecting the health of the digestive system.

3. Leafy vegetables: 

Leafy Vegetables

Kale, lettuce, cabbage, spinach, and bok choy can be a great addition to a fistula diet. Leafy veggies are an excellent source of vitamins, minerals, and other essential nutrients. In addition, they aid in easy digestion and elimination, making you feel fuller for a more extended period.

4. Brown rice: 

Brown Rice

Brown rice has an unpolished outer layer that maintains its high fiber content. As a result, it curbs the chances of constipation. In addition, it promotes a smoother bowel movement, which benefits people suffering from anal fistula.

5. Fish:  


Sea fishes such as salmon, mackerel, and tuna, are good sources of omega-3 fatty acids (EPA and DOHA). Omega-3 fatty acids must be a part of the fistula diet. These fatty acids are essential for maintaining normal intestinal function. For example, they may help to lubricate the gastrointestinal system and keep the regular flow of feces.

6. Cereals: 


Broken wheat, quinoa, brown rice, ragi, and oatmeal are the main grains in the fistula diet. Cereals contain a lot of fiber. Hence, it helps the body to operate at its optimal. It promotes healthy digestion and eases the passage of stools, lessening strain and discomfort.

7. Fruits: 


Fruits with a high fiber content include pears, apples, avocados, and bananas. It reduces the likelihood of anal fistula flare-ups, pain, and inflammation. A variety of fruits should be a part of your regular diet

8. Yogurt and skim milk: 

Yogurt and skim milk

These are healthy dairy options for fistula patients. Yogurt is beneficial because it contains “probiotics,” or good bacteria. It helps to restore a healthy balance of germs in your digestive tract. As a result, it encourages better digestion, resulting in a smoother bowel movement with less discomfort or irritability.

Foods to avoid in Fistula

Foods To Avoid in Fistula

A digestive disorder like a fistula can cause symptoms like indigestion, constipation, bloating, diarrhea, or more severe consequences. Therefore, your physician will always advise you to adjust your diet if you have gastrointestinal conditions or diseases like fistula. 

People suffering from fistula should strictly avoid the foods that induce the diseases. It’s critical to consume nutrients that hasten the healing of fistulas. Avoiding food that can worsen your condition is even more crucial. Following is a list of food to avoid for fistula patients:

Foods in packages: 

It is best to either avoid or consume pre-packaged foods like frozen food and chips in moderation. They hardly have any nutritional value, which is destroyed while freezing.


 Stool passage might become more challenging due to dehydration. Liquor has a significant dehydrating effect on the body. Alcohol consumption in excess might be problematic for those suffering from fistulas.

Spicy foods: 

Indian cuisine frequently uses hot, difficult-to-digest pastes and curries. Try eating simple, non-spicy homemade meals that can be prepared appropriately. Also, if you have an anal fistula, you shouldn’t eat anything spicy that makes your stomach uncomfortable.

Savory foods: 

Constipation can make excretion difficult. Savory food makes you feel bloated. It can irritate your stomach and lead to irritable bowel syndrome.

Dairy products:

 Since they are more challenging to digest due to their high-fat content, it may result in stomach problems. Avoid double-fat milk, cheese, and other heavy milk and cream products.

Fast food:

 Without a doubt, fast food or junk food has a mouth-watering flavor. Fistula patients should stay away from street food vendors. The food might be delicious, but it may be low in nutritional value. Fast food or junk food contains all-purpose flour or “maida”. It should be limited until fistula symptoms subside.

Fried food: 

Avoid fried food if you have an anal fistula. It has a low nutritional value. In addition, it is unhealthy and difficult to digest.

Red meat: 

The fact is that red meat is hard to digest. Due to its shallow fiber content, digestion requires much effort from the stomach. Also, it does not add bulk to the stool. Therefore, avoid a surplus of red meat fried in oil and spices.

Caffeinated drinks: 

Although strong beverages like black coffee or heavy milk tea are undoubtedly delicious, avoid them while recovering from fistula.


Most fistulas occur due to abscess, trauma, surgery, or an infection. Pain, fever, and itching are the most prominent symptoms of fistula. Besides surgery and medications such as antibiotics and immunosuppressants, the diet plays a vital role in healing the fistula. In addition, eat your meals on schedule. Stay away from large meals. Drink enough water. You can fight fistula to live a healthy life with timely intervention, surgery, medications, and a nutritional diet.
