UC and Pregnancy: Eating Well to Gain the Right Amount of Weight

WebMD Feature

Getting the right balance of nutrients is always important when you have ulcerative colitis. But when you're pregnant and have UC, getting a well-balanced diet is absolutely essential to ensure that your baby has enough nutrition to grow and thrive.

Gastrointestinal woes can be an everyday occurrence in people with ulcerative colitis. This painful form of inflammatory bowel disease (IBD), which causes inflammation and sores on the intestinal lining, can really take a toll on diet.

When people are in pain, they don't want to eat, so their nutrition suffers, explains Susan L. Mikolaitis, RD, LDN, clinical research dietitian in the department of gastroenterology and nutrition at Rush University in Chicago.

Here are some ways to boost your nutrition during pregnancy, and even before you get pregnant.

Ulcerative Colitis and Pregnancy Nutrition

When in doubt about what to eat, follow the government's MyPyramid for Pregnancy. This balanced diet includes the nutrients you need during pregnancy:

  • Fortified breads and cereals
  • Vegetables (such as carrots, sweet potatoes, spinach, cooked greens, squash, tomatoes, and sweet red peppers)
  • Fruits (such as cantaloupe, honeydew melon, mangoes, prunes, bananas, apricots, oranges, grapefruit, and avocado)
  • Dairy (low-fat or fat-free milk and yogurt), if not lactose intolerant
  • Meat and beans (cooked beans and peas, nuts and seeds, lean meat and chicken)
  • Fish

Of course, that may be easier said than done. Morning sickness alone could make you swear off many of the foods on the list. And for many women with ulcerative colitis, some of the healthiest foods also may be symptom triggers.

Adjust your diet according to how you feel, but be careful not to avoid the nutritious foods you really need. Instead, get creative to get them in:

Grains. Some people with ulcerative colitis have trouble eating cereals, rice, and breads. Yet these whole grains are important because they are fortified with folic acid, a nutrient that helps prevent spina bifida and other neural tube birth defects.

If whole grains seem to trigger your ulcerative colitis symptoms, you might try quinoa and amaranth. They may be less likely to trigger your UC symptoms.

Fruits and vegetables.  If they bother you, try fruit or vegetable juice instead. Just make sure it's 100% juice, with no added sugar.

"Sugar is not a good thing for patients with IBD," Mikolaitis tells WebMD. Bacteria seem to be partial to disaccharides, a kind of sugar that includes table sugar. "And we think bacteria play a big role in the flare-ups of the disease," she says.

Drink pasteurized juice so you don't get E. coli or another food-borne illness, which may be dangerous for your baby.

Fish. Your doctor may have recommended that you eat more fish because it is high in omega-3 fatty acids. Omega-3s are thought to reduce inflammation, which can be beneficial for an inflammatory disease like ulcerative colitis.

But you need to make sure you don't eat fish that are high in mercury during pregnancy. Stick to low-mercury fish such as salmon, canned light tuna, pollock, catfish, and shrimp. Avoid high-mercury varieties such as king mackerel, tilefish, shark, swordfish, and albacore ("white") tuna.

Finally, make sure you are drinking enough water. Having active ulcerative colitis during pregnancy could mean more diarrhea. This can lead to dehydration if you don’t replace the fluid you lose.
