What to Do During a Crohn’s Flare-Up

A Crohn’s flare-up is an acute period where chronic inflammation of the digestive tract worsens symptoms. This heightened inflammatory activity causes intense discomfort, frequent bowel movements, and systemic fatigue, temporarily disrupting daily life. This guide provides immediate, practical steps for managing this sudden escalation of the condition. The focus is on recognizing severity, adjusting diet, seeking comfort, and managing pharmaceutical interventions during this challenging period.

Recognizing Severity and Seeking Help

A sudden worsening of symptoms requires assessing whether home management is appropriate or if immediate medical attention is necessary. Red flags indicating a severe situation requiring immediate contact with a healthcare provider include a high fever exceeding 100.4°F (38°C) and persistent, severe abdominal pain not alleviated by standard measures.

Uncontrollable vomiting or the inability to keep down fluids signals a need for urgent medical communication. Significant rectal bleeding, especially passing large amounts of bright blood or clots, indicates a serious complication. Dehydration is a serious concern, often indicated by reduced urination, extreme thirst, or dizziness upon standing.

Before calling your gastroenterologist, organize specific details regarding your current condition. Communicate the duration and intensity of your symptoms, and the frequency of bowel movements or vomiting. An established action plan, developed with your care team during remission, streamlines communication and ensures timely guidance.

Nutritional Strategies During a Flare

During an acute flare, the inflamed digestive tract struggles to process complex foods, making temporary dietary adjustments a primary strategy for reducing irritation. The goal is to minimize the volume and fiber content of stool by adopting a low-residue diet. This approach involves choosing foods that are easily digested and leave minimal undigested material in the colon.

Focus your intake on easily tolerated foods:

  • Refined grains, such as white rice, white pasta, and white bread, which are low in fiber.
  • Well-cooked, skinless, and seedless vegetables, like peeled potatoes and soft carrots, can often be tolerated.
  • Lean, tender proteins, such as baked chicken breast, fish, and eggs, provide necessary nutrients without high-fat content.

If symptoms are particularly severe, your doctor may suggest temporarily transitioning to a full liquid diet or utilizing elemental or semi-elemental formulas. These specialized liquid nutrition sources require minimal digestion, allowing the bowel to rest while still providing essential caloric and nutrient support. Dairy products should generally be avoided if lactose intolerance is suspected, as the inflamed gut may produce less lactase enzyme, exacerbating diarrhea.

Strictly avoid foods known to worsen flare symptoms and bowel irritation. This includes high-fat foods, spicy items, and foods containing whole nuts, seeds, or popcorn. Raw vegetables and fruits with skins or seeds should also be temporarily eliminated, as their high-fiber content increases stool bulk and frequency, further irritating the inflamed lining.

Managing Symptoms and Discomfort

Managing the physical discomfort and secondary effects of the flare is important for overall well-being during this acute phase. Physical and mental rest is necessary, as the body expends significant energy fighting inflammation and dealing with frequent bowel movements. Reduced activity and adequate sleep are needed. Stress reduction techniques, such as deep breathing exercises or gentle meditation, can help mitigate the gut-brain axis response, which often amplifies pain perception.

Hydration is a continuous concern due to fluid loss from diarrhea or vomiting. Standard water may not be enough to replace lost electrolytes, making oral rehydration solutions (ORS) highly recommended. These solutions contain the precise balance of sodium, potassium, and glucose needed for efficient absorption. Take frequent, small sips throughout the day to prevent stomach upset, avoiding large volumes at once.

For abdominal cramping and pain, non-pharmaceutical comfort measures can provide relief. Applying a heating pad or a warm water bottle to the abdomen helps relax intestinal muscles, temporarily easing spasms. Taking a warm bath can also offer generalized muscle relaxation and soothe discomfort associated with inflammation.

Frequent trips to the bathroom can lead to perianal skin irritation. To prevent this painful complication, use soft wipes instead of dry toilet paper and apply a protective barrier cream. Products containing zinc oxide or petroleum jelly create a shield against moisture and digestive enzymes, promoting healing and preventing further damage.

Handling Prescribed and OTC Medications

Managing medications during a flare requires strict adherence to your established treatment plan and careful consideration of over-the-counter (OTC) options. Continue taking maintenance medications, such as immunomodulators or biologics, unless your gastroenterologist instructs you to pause them. These therapies are designed to control chronic inflammation, and abruptly stopping them can potentially worsen the flare.

Flares are often treated with a short course of corticosteroids, such as prednisone or budesonide, which work rapidly to reduce acute inflammation. If your doctor prescribes this rescue medication, follow the dosing schedule exactly and understand the tapering process. Sudden cessation can cause adverse effects or a rapid return of symptoms, so never adjust the dose or duration of steroids without medical guidance.

Avoid Nonsteroidal Anti-inflammatory Drugs (NSAIDs), including ibuprofen and naproxen. NSAIDs can irritate the lining of the gastrointestinal tract and may trigger or exacerbate intestinal inflammation. Acetaminophen (paracetamol) is generally considered a safer alternative for managing fever or mild pain, though consultation with a doctor is still recommended.

Using anti-diarrheal medications, such as loperamide, requires caution during a Crohn’s flare. While they slow stool passage, they can potentially increase the risk of toxic megacolon or cause a dangerous bowel obstruction in an inflamed intestine. These should only be taken under the direct supervision and instruction of your healthcare provider who can assess the specific risks based on your current condition.
