They work closely with our gastroenterologists and surgeons to provide consultations and second opinions on biopsies.

Nutritional Support for IBD

We understand the importance of nutrition in managing IBD. We offer all patients the opportunity to consult with an IBD registered dietitian to discuss personalized nutrition. Patients are encouraged to work with an IBD dietitian to:

  • Improve nutritional status and overall well-being
  • Identify and correct any nutritional deficiencies
  • Explore how dietary changes can help manage IBD symptoms
Mental Health Support for IBD

Living alongside an IBD diagnosis can come with a myriad of challenges impacting patients’ daily lives and their mental wellness. Numerous studies have shown that patients with ulcerative colitis or Crohn’s disease are more vulnerable to experiencing symptoms of psychological distress such as anxiety, depression, and medical trauma among others. The mental well-being of IBD patients is especially important to address as stress and mood can have an impact on disease course through potentially triggering disease flares or contributing to behaviors that are barriers to overall wellness. At the Crohn’s and Colitis Center, we offer both single and ongoing consultations with a dedicated inflammatory bowel disease psychologist to address these concerns .

What to Expect When Meeting With the IBD Psychologist

The first session with the IBD psychologist involves completing an assessment during which the psychologist will ask questions about the patient’s experience with IBD, their mood, and other aspects of their life and wellness to get a full picture of the patient’s needs and their unique circumstances. The psychologist then collaborates with the patient on their goals to create a plan for individual therapy. The psychologist offers evidenced-based practices including cognitive behavioral therapy, acceptance and commitment therapy, mindfulness-based stress reduction strategies, and gut-directed clinical hypnosis.

Collaboration with Other Medical Specialists

Patients with Crohn’s disease or ulcerative colitis often need input from various medical specialists like dermatologists, rheumatologists, hepatologists, and infectious disease experts. We work closely with physicians in these specialties to ensure early referral, prompt evaluation, and a comprehensive treatment plan.

We also collaborate closely with high-risk obstetrics/maternal-fetal-medicine (MFM) specialists to co-manage all aspects of pregnancy in patients with IBD. This includes pre-conception counseling, monitoring during pregnancy, and development of care plan for childbirth and postnatal care.

Clinical Pharmacist Consultation

Our clinical pharmacist, specializing in IBD, is an integral part of the Crohn’s and Colitis Center, working closely with all providers and team members. They provide patients with a wide variety of medication-related support, including:

  • One-on-one medication counseling sessions
  • High-risk drug monitoring lab review
  • Vaccination review
  • Pregnancy and lactation questions
  • Drug-drug interactions review
  • Medication access concerns
Infusion Services

We offer infusion services at our main Crohn’s and Colitis locations in Boston, Waltham, and Danvers, for patients needing fluids or medications delivered directly into their bloodstream. Our infusion services are available Monday through Friday from 7:30 a.m. to 4:45 p.m.

Innovative Programs for IBD
  • Ileoanal Pouch: Patients who undergo an ileoanal pouch procedure, commonly known as a “J pouch,” may experience issues such as pouch inflammation, poor function, strictures, and Crohn’s disease of the pouch. Our team of gastroenterologists, surgeons, and radiologists work closely to accurately diagnose pouch-related symptoms and develop the right treatment plan.
  • Older Adults with IBD: Treating older adults with IBD can be complex and involve specific risks, especially when managing multiple conditions like cancer, heart disease, and diabetes. Our team of doctors specializing in geriatric IBD understand these unique challenges and focus on safe, effective treatment to help patients regain their strength and independence.
  • PSC and IBD: Patients with primary sclerosing cholangitis (PSC) are at a higher risk of certain diseases like colorectal and biliary cancer. Our team of IBD gastroenterologists, hepatologists, radiologists, and interventional endoscopists work together to meet every patient’s unique needs. This collaboration also helps patients with other liver diseases related to IBD.
  • Inpatient Care: We provide specialized inpatient care for patients with IBD, ensuring that each patient is overseen by one of our expert gastroenterologists. We also offer transfer opportunities for patients hospitalized at other institutions who require advanced care due to complex needs.
  • Women’s Reproductive Health: In collaboration with the Mass General Department of Obstetrics and Gynecology, our center offers a multidisciplinary approach to high-risk obstetrical care for women with IBD. We provide pre-conception counseling, close monitoring during pregnancy, help with childbirth planning, and postpartum care. Our surgeons are trained in minimally invasive gynecological surgery and have expertise in managing complex issues like rectovaginal fistulas and urogynecological complications related to IBD.
  • Telehealth Services: Our physicians offer telehealth consultations through video platforms, subject to insurance approval. These consultations are available for one-time second opinions or ongoing care.
